submitProofOfAddressOwnership

function submitProofOfAddressOwnership(struct Summa.AddressOwnershipProof[] _addressOwnershipProofs) public

Submit an optimistic proof of multiple address ownership for the Custodian. The proof is subject to an off-chain verification as it's not feasible to verify the signatures of non-EVM chains in an Ethereum smart contract.

Parameters

Name	Type	Description
_addressOwnershipProofs	struct Summa.AddressOwnershipProof[]	The list of address ownership proofs

submitCommitment

function submitCommitment(uint256 mstRoot, uint256[] rootBalances, struct Summa.Cryptocurrency[] cryptocurrencies, uint256 timestamp) public

Submit liabilities commitment for the Custodian

Parameters

Name	Type	Description
mstRoot	uint256	Merkle sum tree root of the Custodian's liabilities
rootBalances	uint256[]	The total sums of the liabilities included into the Merkle sum tree
cryptocurrencies	struct Summa.Cryptocurrency[]	The cryptocurrencies included into the Merkle sum tree
timestamp	uint256	The timestamp at which the Custodian took the snapshot of its assets and liabilities

verifyInclusionProof

function verifyInclusionProof(bytes proof, uint256[] publicInputs, uint256 timestamp) public view returns (bool)

Verify the proof of user inclusion into the liabilities MST

Parameters

Name	Type	Description
proof	bytes	ZK proof
publicInputs	uint256[]	proof public inputs
timestamp	uint256	The timestamp at which the Custodian took the snapshot of its assets and liabilities to generate this proof
