- Paste the address and ABIEnter the contract address and paste the ABI (a JSON array). The page lists every method with an input for each argument. A wrong ABI leaves you with an empty method list.
- Read methods: results right awayMethods marked view or pure need no signature — one click and you have the result. Balances, config values and owner checks all live here.
- Write methods: confirm one at a timeWrites are simulated locally first, then you confirm in your wallet. A bad argument or an unmet condition fails during simulation, before any gas is spent.
- Loop calls (optional)Need to fire the same call many times with the same arguments — flipping a switch over and over, say? Paste a local private key and loop it: 1 to 50 calls, up to 60 seconds apart. The key is used in browser memory only and is never uploaded.
Careful · The ABI decides everything
This tool does not guess a contract's methods: anything missing from the ABI cannot be called, and a wrong argument type fails at encoding. If you don't have the ABI, copy the verified one from a block explorer.
