Bridge (bridge_) endpoints in Frietor Chains

bridge_generateExitProof

Returns the proof for a given exit event. Used by users that want to exit the Frietor chain and withdraw tokens to Ethereum Sepolia (for Saar Testnet) and Ethereum Mainnet (for Mainnet).

Parameters

• exitID - ID of the exit event submitted by L2StateSender contract when the user wants to exit the L2 contract.

Returns

Object - A proof object containing:

Array of hashes - representing the proof of membership of a given exit event on some checkpoint. Map- containing a leaf index of given exit event in the Merkle tree, Exit event and block number in which checkpoint that contains a given exit event was submitted to the rootchain.

bridge_getStateSyncProof

Returns the proof for a given state sync event. Used by users (Relayer) when they want to execute a state change on the childchain (for example, depositing funds from L1 to L2).

Parameters

• stateSyncID - ID of the state sync event submitted by StateSender contract when the user wants to execute a state change on the Frietor Chain.

Returns

Object - A proof object containing:

• Array of hashes - representing the proof of membership of a given state sync event on some checkpoint.
• Map- containing a leaf index of given state sync event in the Merkle tree, State sync event and block number in which checkpoint that contains a given state sync event was submitted to the rootchain.
