SpellzCode — ERC-20 token approval check on Base
https://agent-data-tools.revmesh2074.workers.dev/base-allowanceOverview
Check how much of a wallet's ERC-20 token a spender contract is approved to move on Base: the raw and formatted allowance, the token symbol and decimals, and whether the approval is unlimited. Use before a swap or deposit to see if an approve transaction is needed, and to audit a wallet for risky unlimited approvals.
