    Risk summary

    Principle of operation

    Symbiosis uses a MPC relayer network to facilitate cross-chain transfers. An AMM on BOBA BNB is used to perform swaps.

    Transfers are externally verified

    Requests are watched by a relayer network that, utilizing MPC, signs off swaps and token minting.

    • Users can be censored if MPC nodes decide to censor certain transactions (CRITICAL).

    • Funds can be stolen if MPC nodes decide to maliciously takeover them or there is an external exploit which will result in signing malicious transaction (CRITICAL).

    • Funds can be lost if MPC nodes lose their private keys (CRITICAL).

    Destination tokens

    Received tokens can be wrapped tokens or native tokens depending on the destination network.

    • Funds can be lost if destination token contract is maliciously upgraded or not securely implemented (CRITICAL).


    The system uses the following set of permissioned addresses:

    Multisig 0x5112…106a

    This multisig can upgrade the BridgeV2 and Portal contracts.
