function confirmAttestation(AttestationData calldata attestationData_, bytes calldata sig_) external;

minBalance¶

function minBalance() external view returns (uint256);

minWindow¶

function minWindow() external view returns (uint256);

maxWindow¶

function maxWindow() external view returns (uint256);

getAccountAttestationDataKeys¶

function getAccountAttestationDataKeys(string calldata iban_, string calldata currency_) external view returns (bytes32[] memory);

getAccountLastAttestationData¶

function getAccountLastAttestationData(string calldata iban_, string calldata currency_) external view returns (AttestationData memory);

getAccountLastAttestationDataKey¶

function getAccountLastAttestationDataKey(string calldata iban_, string calldata currency_) external view returns (bytes32);

getAttestationData¶

function getAttestationData(bytes32 attestationDataKey_) external view returns (AttestationData memory);

getTokenAddress¶

function getTokenAddress(string memory iban_, string memory currency_) external view returns (address);

getAttestationDataHash¶

function getAttestationDataHash(AttestationData calldata attestationData_) external view returns (bytes32);

getAccountAttestationKey¶

function getAccountAttestationKey(string calldata currency_, string calldata iban_) external pure returns (bytes32);

Events¶

NestorFundDepositAttestationTokenUpdated¶
