React API

For react hooks we recomend using the wagmi cli with the etherscan plugin and react plugin to automatically generate react hooks around AttestationStation.

Use createKey and createValue to convert your raw keys and values into bytes that can be used in AttestationStation contract calls

Use parseString, parseBool, parseAddress and parseNumber to convert values returned by AttestationStation to their correct data type.

For convenience we also export the hooks here:

• useAttestationStationAttestation - Reads attestations with useContractRead
• useAttestationStationVersion - Reads attestation version
• useAttestationStationAttest - Wraps useContractWrite with AttestationStation abi calling attest
• usePrepareAttestationStationAttest - Wraps usePrepare with AttestationStation abi calling attest
• useAttestationStationAttestationCreatedEvent - Wraps useContractEvents for Created events

Also some more hooks exported by the cli but these are likely the only ones you need.
