Benchmarks for implementations of the ERC20 standard.
Note: When comparing, keep in mind that Solmate and Maple implements ERC-2612 permit so it's more fairt to compare them against OpenZeppelin Permit and not the raw OpenZeppelin implementation.
- deploy: How much gas to deploy the contract as is?
- transfer (toOwner): How much gas to transfer tokens to an account that already owns more than 0 tokens?
- transfer (toNonOwner): How much gas to transfer tokens to an account that owns 0 tokens?
- transferFrom (toOwner): How much gas for an operator to transfer tokens from one account to another that already owns more than 0 tokens?
- transferFrom (toNonOwner): How much gas for an operator to transfer tokens from one account to another that owns 0 tokens?
- approve: How much gas to approve an account to spend x amount of tokens?
- totalSupply: How much gas to check the total supply of tokens?
- balanceOf: How much gas to check the balance of an account?
- allowance: How much gas to check how many tokens an operator can spend on behalf of another account?
