Contracts TS

codecov

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

console.log(l2OutputOracleAddresses[10], abi)

Addresses are also exported as an object for convenience.

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

console.log(addresses.l2OutputOracle[10])

@eth-optimism/contracts-ts/react

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

const component = () => {
  const { data, error, loading } = useAddressManagerAddress()
  if (loading) {
    return <div>Loading</div>
  }
  if (err) {
    return <div>Error</div>
  }
  return <div>{data}</div>
}

@eth-optimism/contracts-ts/actions

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