Interface Standards

This page is a collection of methods that a resolver MAY implement

Usage	Interface ID
Read Ethereum Address	addr(bytes32 node) view returns (address)
Read Multicoin Address	addr(bytes32 node, uint coinType) view returns (byte memory)
Read Content Hash	contenthash(bytes32 node) view returns (bytes memory)
Read Text Record	text(bytes32 node, string key) view returns (string memory)
Read Contract ABI	ABI(bytes32 node, uint256 contentTypes) view returns (uint256, bytes memory)
Read Public Key	pubkey(bytes32 node) view returns (bytes32 x, bytes32 y)
Read Name (for reverse records)	name(bytes32 node) view returns (string memory)
Write Ethereum Adress	setAddr(bytes32 node, address addr)
Set Multicoin Address	setAddr(bytes32 node, uint coinType, bytes calldata a)
Write Content Hash	setContenthash(bytes32 node, bytes calldata hash)
Write Text Record	setText(bytes32 node, string calldata key, string calldata value)
Write Contract ABI	setABI(bytes32 node, uint256 contentType, bytes calldata data)
Write Public Key	setPubkey(bytes32 node, bytes32 x, bytes32 y)
Write Name (for reverse records)	setName(bytes32 node, string calldata name)
Batch Read/Write	multicall(bytes[] calldata data) view returns (bytes[] memory results)

Check Interface Support

function supportsInterface(bytes4 interfaceID) external pure returns (bool)

Read Ethereum Address

Function

addr(bytes32 node) view returns (address)

Interface ID is 0x3b3b57de

ENSIP-1 / EIP-137

Outputs

Ethereum address or the zero address if no address is set.

Read Multicoin Address

Function

addr(bytes32 node, uint coinType) view returns (byte memory)

Interface ID is 0xf1cb7e06

ENSIP-9 / [EIP-2304](https://eips.ethereum.org/EIPS/eip-2304)

Outputs

Cryptocurrency address in its native binary format. For example, the Bitcoin address `1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa` base58check decodes to the 21 bytes `0062e907b15cbf27d5425399ebf6f0fb50ebb88f18` then scriptPubkey encodes to 25 bytes `76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac` whereas the BNB address `bnb1grpf0955h0ykzq3ar5nmum7y6gdfl6lxfn46h2` Bech32 decodes to the binary representation `40c2979694bbc961023d1d27be6fc4d21a9febe6`. A zero-length string ("") will be returned if the specified coin type is not set.

Read Content Hash

Function

contenthash(bytes32 node) view returns (bytes memory)

Interface ID is 0xbc1c58d1

ENSIP-7 / EIP-1577

Read Text Record

Function

text(bytes32 node, string key) view returns (string memory)

Interface ID is 0x59d1d43c

ENSIP-5 / EIP-634

Outputs

The value of the text record associated with key, or the empty string if no such record exists.

Read Contract ABI

Function

ABI(bytes32 node, uint256 contentTypes) view returns (uint256, bytes memory)

Interface ID is 0x2203ab56

ENSIP-4 / EIP-205

Outputs

ABI returns a two-tuple of the content type ID and the ABI data. If no data of the appropriate content type ID was found, 0 is returned for the content type ID, and the ABI data will be the empty string.

Read Public Key

Function

pubkey(bytes32 node) view returns (bytes32 x, bytes32 y)

Interface ID is 0xc8690233

ENSIP- / EIP-619

Outputs

The ECDSA SECP256k1 public key for node, as a 2-tuple (x, y). If no public key is set, (0, 0) is returned.
