@eth-optimism/contracts-ts

Contracts TS


ABI and Address constants + generated code from @eth-optimism/contracts-bedrock/ for use in TypeScript.

Much of this package is generated. See CODE_GEN.md for instructions on how to generate.

#### @eth-optimism/contracts-ts

The main entrypoint exports constants related to contracts bedrock as const. As const allows it to be used in TypeScript with stronger typing than importing JSON.

- Exports contract abis.
- Exports contract addresses

``typescript
import {
l2OutputOracleProxyABI,
l2OutputOracleAddresses,
} from '@eth-optimism/contracts-ts'

console.log(l2OutputOracleAddresses[10], abi)
`

Addresses are also exported as an object for convenience.

`typescript
import { addresses } from '@eth-optimism/contracts-ts'

console.log(addresses.l2OutputOracle[10])
`

#### @eth-optimism/contracts-ts/react

- All React hooks @eth-optimism/contracts-ts/react

`typescript
import { useAddressManagerAddress } from '@eth-optimism/contracts-ts/react'

const component = () => {
const { data, error, loading } = useAddressManagerAddress()
if (loading) {
return

`typescript
import { readSystemConfig } from '@eth-optimism/contracts-ts/actions'
console.log(await readSystemConfig())
``
