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

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).
