Testing on Optimistic Test Networks
You can find the chainid and supporting information for OP Goerli, our test network, using these endpoints. To obtain ETH and tokens (both ERC-20 and NFT) from faucets, see here.
This page shows some additional testing utilities that you might find useful.
# ERC-20 tokens
We have several ERC-20 testing token contracts.
This token is an implementation of ERC-20, with the addition of faucet, a function that mints for the caller 1000 tokens to facilitate testing.
Additionally, both OP Mainnet and OP Goerli have WETH at address 0x4200000000000000000000000000000000000006 (opens new window).

# The bridge
The OUTb token is supported by the bridge on Goerli.
See this tutorial (opens new window) to see how to use it.
# ERC-721 tokens
We have an ERC-721 token on OP Goerli at address 0x38abA480f2bA7A17bC01EE5E1AD64fCedd93EfE7 (opens new window).
It is the OpenZeppelin ERC-721 token contract with the addition of faucet.
Just call the faucet function to get as many NFT tokens as you need.
