Reckon

On Monad, a transaction is charged its full declared gas limit even when it reverts. I burned real MON finding that out the hard way. So I built Reckon: it checks every transaction before you sign, refuses the ones that would fail before your wallet even opens, flags risky approvals instead of blindly signing them, and scans your wallet's real history so you can revoke what you forgot about. Everything in the demo is a real Monad testnet transaction. Nothing is mocked. I learned that Monad's gas model punishes failure far harder than Ethereum's, and that no wallet warns you before it happens.
