# edgeX v1

Markdown version of https://l2beat.com/layer2s/projects/edgex

## Summary

**Warning:** This project is archived and no longer maintained.

**Warning:** The edgeX v1 StarkPerpetual contract was frozen on 14th August 2026. It can no longer process trades, deposits or state updates. Remaining funds can only be recovered via the escape hatch.

**Warning:** Critical contracts can be upgraded by an EOA which could result in the loss of all funds.

**Warning:** Why is the project listed in others? The data availability committee threshold is too low. Consequence: projects with a low DAC threshold rely on the honesty of few entities to safely attest data availability on Ethereum. These entities can collude with the proposer to finalize an unavailable state, which can cause loss of funds.

## Risk summary

**Warning:** 1 address has unverified source code (CRITICAL).

- StarkPerpetual: 0xfAaE2946e846133af314d1Df13684c89fA7d83DD

### Funds can be stolen if

1. a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL),
2. the source code of unverified contracts contains malicious code (CRITICAL).

### Funds can be lost if

3. the external data becomes unavailable (CRITICAL),
4. the user is unable to find the counterparty for the force trade.

### Users can be censored if

5. the committee restricts their access to the external data,
6. the operator refuses to include their transactions. However, there exists a mechanism to independently exit the system.

### MEV can be extracted if

7. the operator exploits their centralized position and frontruns user transactions.

## Risk analysis

**Warning:** 1 address has unverified source code (CRITICAL).

- StarkPerpetual: 0xfAaE2946e846133af314d1Df13684c89fA7d83DD

**Warning:** Critical contracts can be upgraded by an EOA which could result in the loss of all funds.

### Sequencer failure

Force via L1 (7d delay; sentiment: good)

Users can force the sequencer to include a trade or a withdrawal transaction by submitting a request through L1. If the sequencer censors or is down for 7d, users can use the exit hatch to withdraw their funds. Users are required to find a counterparty for the trade by out of system means.

### State validation

Validity proofs (ST) (No execution delay; sentiment: good)

STARKs are zero knowledge proofs that ensure state correctness.

### Data availability

External (DAC) (sentiment: bad)

Proof construction relies fully on data that is NOT published onchain. There exists a Data Availability Committee (DAC) with a threshold of 2/6 that is tasked with protecting and supplying the data.

### Exit window

None (sentiment: bad)

There is no window for users to exit in case of an unwanted upgrade since contracts are instantly upgradable.

### Proposer failure

Use escape hatch (sentiment: good)

Users are able to trustlessly exit by submitting a Merkle proof of funds. Positions will be closed using the average price from the last batch state update.

## Data availability

Set of parties responsible for signing and attesting to the availability of data.

### Risk analysis

#### Economic security

None (sentiment: bad)

There are no onchain assets at risk of being slashed in case of a data withholding attack, and the committee members are not publicly known.

#### Fraud detection

None (sentiment: bad)

There is no fraud detection mechanism in place. A data withholding attack can only be detected by nodes downloading the full data from the DA layer.

#### Committee security

2/6 (sentiment: bad)

The committee does not meet basic security standards, either due to insufficient size, lack of member diversity, or poorly defined threshold parameters. The system lacks an effective DA bridge and it is reliant on the assumption of an honest sequencer, creating significant risks to data integrity and availability.

#### Upgradeability

Immutable (sentiment: bad)

The bridge smart contract is immutable and cannot be updated. The bridge committee security is low and cannot be improved.

#### Relayer failure

Self propose (sentiment: good)

Anyone can relay data availability commitments to the DA bridge. In case of current relayer failure, users can collect attestations from committee members and propose new data availability commitments to the DA bridge.

### Technology

#### Architecture
![starkex architecture](https://l2beat.com/images/da-layer-technology/starkex/architecture.png#center)

The Starkware application utilizes a data availability solution that relies on a Committee Service to ensure data persistence. This architecture comprises the following components:

- **Availability Gateway**: The primary interface provided by the operator for committee members to access new batch information and submit signed availability claims.
- **Data Availability Committee (DAC)**: A group of nodes responsible for storing state data associated with each Merkle root and attesting to data availability by signing claims.
- **Data Batches**: Collections of transactions processed in batches that update the state of accounts, resulting in a new Merkle root representing the updated state.

Committee members run services that interact with the Availability Gateway to obtain information about new batches and submit their signed availability claims. Each batch includes a unique batch_id, a reference to a previous batch, and a list of account updates.
Committee members combine this information with data from the reference batch to compute the new state and verify the Merkle root.

When the operator produces a new batch, it must be signed by a minimum number of committee members—as defined by the application's configuration—for it to be accepted onchain.
This includes all members designated as mandatory signers. If the operator attempts to submit a batch without the required signatures, it will be rejected, thereby ensuring that data remains available and consistent.

Committee members are expected to maintain a database that stores the data associated with each batch, making use of storage solutions with a replication factor of at least 2.

#### DA Bridge Architecture
![starkex bridge architecture](https://l2beat.com/images/da-bridge-technology/starkex/architectureL2.png#center)

The DA commitments are posted to the destination chain, using the Committee Verifier contract as a DA bridge.
The DA commitment consists of a data hash of the transaction batch the Committee has signed off on and a concatenation of ec-signatures by signatories.

The Committee Verifier contract verifies the signatures and the data hash and if the required threshold of Committee members has signed off on the data, the hash is stored as a registeredFact in the StarkEx contract.
In a separate transaction, the operator calls the updateState() function on the StarkEx contract to update the state.
Before the state update is accepted, the StarkEx contract verifies the transaction public inputs by calling the isValid() function, which verifies the hash derived from state update inputs matches the hash stored by the Committee Verifier contract.

**Risks**

- Funds can be lost if a malicious committee signs a data availability attestation for an unavailable transaction batch.

## State validation

### Validity proofs

Each update to the system state must be accompanied by a ZK proof that ensures that the new state was derived by correctly applying a series of valid user transactions to the previous state. These proofs are then verified on Ethereum by a smart contract. The system state is represented using Merkle roots.

##### Verification steps

These steps reproduce the current 1,166-felt SHARP outer bootloader on Linux.

Dependencies: Git, Bazelisk configured to use Bazel 7.4.1, JDK 21, GMP development headers, Python 3, and Foundry `cast`.

1. Check out the exact public source revision:

```bash
git clone https://github.com/starkware-libs/cairo-lang.git
cd cairo-lang
git checkout 56407b69f3f19f69302a8623baa8c5f71f967eed
```

The Cairo compiler version at this revision is `0.15.0a0`. The entrypoint is `src/starkware/cairo/bootloaders/bootloader/bootloader.cairo`.

2. Build the official proof-mode target:

```bash
USE_BAZEL_VERSION=7.4.1 bazelisk build \
  //src/starkware/cairo/bootloaders/bootloader:bootloader_program
```

The destination for the compiled program will be printed by the build script, the instruction array will be in the `"data"` json field in hex format. The target uses `--proof_mode --debug_info_with_source`.

3. Check that the compiled instruction array is identical to the one pinned by the immutable Ethereum contract at `0x24105e6697AdD9B4B1BDE04079a91BDFCCa24A47`, which could be fetched by calling:

```bash
cast call 0x24105e6697AdD9B4B1BDE04079a91BDFCCa24A47 \
  'getCompiledProgram()(uint256[1166])' \
  --rpc-url "$ETHEREUM_RPC_URL" \
  --json > /tmp/sharp_outer_bootloader_onchain.json
```

##### Verification steps

This value is not a hash of a single program. It is a Pedersen hash chain committing to the ordered 30-entry `supported_cairo_verifier_program_hashes` list from [supported_program_hashes.json](https://github.com/starkware-libs/cairo-lang/blob/cf9bf972bede402a125e8638bb258e77563ae933/src/starkware/cairo/bootloaders/bootloader/supported_program_hashes.json) at cairo-lang `cf9bf972bede402a125e8638bb258e77563ae933` (v0.14.3). The list contains the program hashes of all Cairo verifier programs that the SHARP bootloader accepts for recursive proof verification:

- 21 entries are Stone Cairo verifiers built from the same cairo-lang commit: 7 layouts (`dex`, `recursive`, `small`, `starknet`, `starknet_with_keccak`, `dynamic`, `recursive_with_poseidon`), each hashed with the pedersen (entries 1-7), poseidon (11-17) and blake (21-27) program hash function.
- 9 entries are Stwo Cairo verifiers built from [stwo-cairo](https://github.com/starkware-libs/stwo-cairo/tree/sharp-7.4.RC3) at tag `sharp-7.4.RC3` (commit `9b93cc39c87838cee3132ee1f8237590700f0689`): 3 feature builds (`poseidon252_verifier` with poseidon output packing, `qm31_opcode` with poseidon output packing, `qm31_opcode` with blake output packing), each hashed with pedersen (entries 8-10), poseidon (18-20) and blake (28-30).

1. Reproduce the 21 Stone verifier hashes following [these steps](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/stone_verifier_steps.md).
2. Reproduce the 9 Stwo verifier hashes following [these steps](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/stwo_verifier_steps.md). You will need [this stwo_features.patch](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/stwo_features.patch) and [this hash_stwo_verifiers.py helper script](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/hash_stwo_verifiers.py).
3. From the cairo-lang checkout, using a python 3.9 environment with `scripts/requirements.txt` installed, compute the commitment to the now-verified list:

```
PYTHONPATH=src python -c "
import json
from starkware.cairo.common.hash_state import
    compute_hash_on_elements
doc = json.load(open('src/starkware/cairo/
    bootloaders/bootloader/supported_program_hashes.json'))
print(compute_hash_on_elements([int(h, 16)
    for h in doc['supported_cairo_verifier_program_hashes']]))
"
```

The output should be the program hash.

EdgeX v1 StarkEx deployment stops operating and freezes due to a forced withdrawal on L1 not being processed for 7 days.
Observable trading activity stopped even before this, so it's a planned sunset of StarkEx deployment as a part of migration to EDGE L3 on arbitrum.

### [2026-07-13 10:31 UTC](https://l2beat.com/layer2s/projects/edgex?update=cb9e7864) (2 changes)

Added a DAC member and increased DAC min signatures required to 2.

### [2026-07-08 09:11 UTC](https://l2beat.com/layer2s/projects/edgex?update=b1fb5752) (1 change)

Updated global configuration hash that commits to a set of offchain configs. Global configuration contains perp dex parameters and asset info for each synthetic asset: https://docs.starkware.co/starkex/perpetual/on-chain-configuration-perpetual-trading.html#global_configuration.

### [2026-07-06 10:18 UTC](https://l2beat.com/layer2s/projects/edgex?update=b2fea368) (9 changes)

Upgraded PerpetualTokensAndRamping facet of Stark diamond to an unverified contract. The diamond changed to not finalized, so probably there will be further upgrades.

## Operator

### The system has a centralized operator

The operator is the only entity that can propose blocks. A live and trustworthy operator is vital to the health of the system. Typically, the Operator is the hot wallet of the StarkEx service submitting state updates for which proofs have been already submitted and verified.

**Risks**

- MEV can be extracted if the operator exploits their centralized position and frontruns user transactions.

**References**

- [Operator - StarkEx documentation](https://docs.starkware.co/starkex/perpetual/shared/contract-management.html#operator_perpetual)

### Users can force exit the system

Force exit allows the users to escape censorship by withdrawing their funds. The system allows users to force the withdrawal of funds by submitting a request directly to the contract onchain. The request must be served within 7d. If this does not happen, the system will halt regular operation and permit trustless withdrawal of funds. Perpetual positions can also be force closed before withdrawing, however this requires the user to find the counterparty for the trade themselves.

**Risks**

- Users can be censored if the operator refuses to include their transactions. However, there exists a mechanism to independently exit the system.
- Funds can be lost if the user is unable to find the counterparty for the force trade.

- [Forced Trade - StarkEx documentation](https://docs.starkware.co/starkex/perpetual/forced-actions-escape-hatch-perpetual.html#forcedtrade)

## Withdrawals

### Regular exit

The user initiates the withdrawal by submitting a regular transaction on this chain. When the block containing that transaction is settled the funds become available for withdrawal on L1. ZK proofs are required to settle blocks. Finally the user submits an L1 transaction to claim the funds.

**References**

- [Withdrawal - StarkEx documentation](https://docs.starkware.co/starkex/perpetual/withdrawal-perpetual.html)

### Forced exit

If the user experiences censorship from the operator with regular exit they can submit their withdrawal requests directly on L1. The system is then obliged to service this request. Once the force operation is submitted and if the request is serviced, the operation follows the flow of a regular exit.

**References**

- [Forced Operations - StarkEx documentation](https://docs.starkware.co/starkex/perpetual/shared/README-forced-operations.html)
- [Forced Withdrawal - StarkEx documentation](https://docs.starkware.co/starkex/perpetual/perpetual-trading-forced-withdrawal-and-forced-trade.html#forced_withdrawal)
- [Forced Trade - StarkEx documentation](https://docs.starkware.co/starkex/perpetual/perpetual-trading-forced-withdrawal-and-forced-trade.html#forced_trade)

### Emergency exit

If the enough time deadline passes and the forced exit is still ignored the user can put the system into a frozen state, disallowing further state updates. In that case everybody can withdraw by submitting a merkle proof of their funds with their L1 transaction.

  - SHARPVerifierCallProxy [via: - acting directly with 8d delay]
- Can interact with SHARPVerifierCallProxy
  - Administer the CallProxy's `GOVERNANCE_ADMIN` and role-admin hierarchy. This AccessControl role is separate from the outer proxy governor that schedules implementation upgrades
  - Grant and revoke application roles, including the `APP_GOVERNOR` role that controls caller-specific fallback routes
  - Route fallback calls from specific callers to a still-active registry in the default verifier's reference chain. This principally determines which verifier and bootloader configuration processes their proof submissions; the proxy's explicit `isValid` entry point always queries the default target

Permissionless commitment calculator and registry used by the Solidity STARK verifiers. Anyone may submit a public-memory page and interaction elements; the contract computes its hash and cumulative product and registers the fact key committing to them, which the CPU verifier must bind to the proof. It is part of the proof verifier, not an application-level program registry. A malicious or nonconforming implementation can break public-memory soundness; binding to a different honest registry generally causes a liveness failure instead.

Upgradeable call router through which Starknet and other applications access SHARP fact registries. It uses `call`, not `delegatecall`, so facts and immutable verifier configuration remain at each target registry. The explicit `isValid` entry point always queries the default target. Other calls handled by the fallback, principally proof submissions, can be routed per caller to a still-active registry in the default target's reference chain. The default target can be replaced by SHARP Multisig after 8d.
- Roles:
  - **admin**: SHARP Multisig
  - **appGovernor**: SHARP Multisig
  - **appRoleAdmin**: SHARP Multisig
  - **governanceAdmin**: SHARP Multisig

Can be upgraded by: SHARP Multisig with 8d delay

Permissionless commitment calculator and registry used by the Solidity STARK verifiers. Anyone may submit a public-memory page and interaction elements; the contract computes its hash and cumulative product and registers the fact key committing to them, which the CPU verifier must bind to the proof. It is part of the proof verifier, not an application-level program registry. A malicious or nonconforming implementation can break public-memory soundness; binding to a different honest registry generally causes a liveness failure instead.

Immutable GPS statement verifier shared by Starknet and other StarkWare systems. It verifies a STARK proof of the exact Cairo bootloader stored onchain, forces the bootloader configuration into public memory, and registers a fact for every bootloader task. A fact is also considered valid when it exists in the time-limited reference fact registry.

Implementation used in: [Paradex](https://l2beat.com/layer2s/projects/paradex#SHARPVerifier_2026_13_3), [Starknet](https://l2beat.com/layer2s/projects/starknet#SHARPVerifier_2026_13_3)

##### Verification steps

These steps reproduce the current 1,166-felt SHARP outer bootloader on Linux.

Dependencies: Git, Bazelisk configured to use Bazel 7.4.1, JDK 21, GMP development headers, Python 3, and Foundry `cast`.

1. Check out the exact public source revision:

```bash
git clone https://github.com/starkware-libs/cairo-lang.git
cd cairo-lang
git checkout 56407b69f3f19f69302a8623baa8c5f71f967eed
```

The Cairo compiler version at this revision is `0.15.0a0`. The entrypoint is `src/starkware/cairo/bootloaders/bootloader/bootloader.cairo`.

2. Build the official proof-mode target:

```bash
USE_BAZEL_VERSION=7.4.1 bazelisk build \
  //src/starkware/cairo/bootloaders/bootloader:bootloader_program
```

The destination for the compiled program will be printed by the build script, the instruction array will be in the `"data"` json field in hex format. The target uses `--proof_mode --debug_info_with_source`.

3. Check that the compiled instruction array is identical to the one pinned by the immutable Ethereum contract at `0x24105e6697AdD9B4B1BDE04079a91BDFCCa24A47`, which could be fetched by calling:

```bash
cast call 0x24105e6697AdD9B4B1BDE04079a91BDFCCa24A47 \
  'getCompiledProgram()(uint256[1166])' \
  --rpc-url "$ETHEREUM_RPC_URL" \
  --json > /tmp/sharp_outer_bootloader_onchain.json
```

##### Verification steps

The steps below are supposed to be run on linux OS. They could also be run on macOS, but several tweaks need to be made: update from `lru-dict==1.1.8` to `lru-dict==1.3.0` in `scripts/requirements.txt` and update `python_interpreter` in `bazel_utils/python/stub.sh` to the correct location.

1. Install [bazel](https://bazel.build) version 7.4.1 and `gmp` library using [brew](https://brew.sh):
```
brew install bazelisk
USE_BAZEL_VERSION=7.4.1 bazelisk version
brew install gmp  # or sudo apt-get install libgmp-dev
```

2. On linux, install JDK if you don't have it: `sudo apt install openjdk-21-jre`.

3. Check out the correct commit of <https://github.com/starkware-libs/cairo-lang/tree/master> repo:

##### Verification steps

This value is not a hash of a single program. It is a Pedersen hash chain committing to the ordered 30-entry `supported_cairo_verifier_program_hashes` list from [supported_program_hashes.json](https://github.com/starkware-libs/cairo-lang/blob/cf9bf972bede402a125e8638bb258e77563ae933/src/starkware/cairo/bootloaders/bootloader/supported_program_hashes.json) at cairo-lang `cf9bf972bede402a125e8638bb258e77563ae933` (v0.14.3). The list contains the program hashes of all Cairo verifier programs that the SHARP bootloader accepts for recursive proof verification:

- 21 entries are Stone Cairo verifiers built from the same cairo-lang commit: 7 layouts (`dex`, `recursive`, `small`, `starknet`, `starknet_with_keccak`, `dynamic`, `recursive_with_poseidon`), each hashed with the pedersen (entries 1-7), poseidon (11-17) and blake (21-27) program hash function.
- 9 entries are Stwo Cairo verifiers built from [stwo-cairo](https://github.com/starkware-libs/stwo-cairo/tree/sharp-7.4.RC3) at tag `sharp-7.4.RC3` (commit `9b93cc39c87838cee3132ee1f8237590700f0689`): 3 feature builds (`poseidon252_verifier` with poseidon output packing, `qm31_opcode` with poseidon output packing, `qm31_opcode` with blake output packing), each hashed with pedersen (entries 8-10), poseidon (18-20) and blake (28-30).

1. Reproduce the 21 Stone verifier hashes following [these steps](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/stone_verifier_steps.md).
2. Reproduce the 9 Stwo verifier hashes following [these steps](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/stwo_verifier_steps.md). You will need [this stwo_features.patch](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/stwo_features.patch) and [this hash_stwo_verifiers.py helper script](https://l2beat.com/files/starkware_proghash_artifacts/cf9bf972bede402a125e8638bb258e77563ae933/hash_stwo_verifiers.py).
3. From the cairo-lang checkout, using a python 3.9 environment with `scripts/requirements.txt` installed, compute the commitment to the now-verified list:

```
PYTHONPATH=src python -c "
import json
from starkware.cairo.common.hash_state import
    compute_hash_on_elements
doc = json.load(open('src/starkware/cairo/
    bootloaders/bootloader/supported_program_hashes.json'))
print(compute_hash_on_elements([int(h, 16)
    for h in doc['supported_cairo_verifier_program_hashes']]))
"
```

The output should be the program hash.
