The typescript sdk provides a clean [wagmi](https://wagmi.sh/) based interface for reading and writing to the attestation station
### See [sdk docs]() for usage instructions
### See [sdk docs](https://github.com/ethereum-optimism/optimism/blob/develop/packages/atst/docs/sdk.md) for usage instructions
## atst cli
The cli provides a convenient cli for interacting with the attestation station contract
TODO put a gif here of using it
## React instructions
## React API
For react hooks we recomend using the [wagmi cli](https://wagmi.sh/cli/getting-started) with the [etherscan plugin](https://wagmi.sh/cli/plugins/etherscan) and [react plugin](https://wagmi.sh/cli/plugins/react) to automatically generate react hooks around the attestation station. See [example/react](http://todo.todo.todo) for an example.

Use `parseAttestationBytes` and `stringifyAttestationBytes` to parse and stringify attestations before passing them into wagmi hooks.
Use `createKey` and `createValue` to convert your raw keys and values into bytes that can be used in the attestation station contract calls
Use `parseString`, `parseBool`, `parseAddress` and `parseNumber` to convert values returned by attestation station 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 attestation station abi calling attest
`usePrepareAttestationStationAttest` - Wraps usePrepare with attestation station 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.

### parseAttestationBytes
### Parsing bytes
Parses raw bytes from the attestation station based on the type.
These utilities for parsing bytes are provided:
Note: `readAttestation` and `readAttestations` already parse the bytes so this is only necessary if reading attestations directly from chain instead of through this sdkA
`parseAddress`
`parseNumber`
`parseBool`
`parseString`
Note: `readAttestation` and `readAttestations` already parse the bytes so this is only necessary if reading attestations directly from chain instead of through this utility
Set key, about, creator, or value to `null` to not include that filter
## Tutorial
For a tutorial on using the attestation station in general, see out tutorial as well as other Optimism related tutorials in our [optimism-tutorial](https://github.com/ethereum-optimism/optimism-tutorial/tree/main/ecosystem/attestation-station#key-values) repo
