SCOUT
checking service…
Pre-sign transaction check · Live on OKX.AI

Every wallet check runs after you sign. Scout runs before.

Scout simulates the exact transaction sitting in your wallet — against live chain state — and tells you in plain English what it actually does. Before you approve it.

01Live demo · real engine, real mainnet state

Pick a transaction. Scout simulates it for real.

This page calls the same engine the paid API runs — nothing here is mocked.

Pick a scenario above. The verdict you'll see is computed live.
02Why this doesn't exist anywhere else

Every other tool scans what already exists. Scout checks what you're about to do.

Wallets are drained at the moment you sign — and nothing checks the transaction itself. Scout inspects the pending calldata: the exact bytes your wallet is about to authorize.

01

Give Scout the transaction

chainId, from, to, value, calldata — exactly what your wallet shows before you sign.

02

It executes it — for real

Simulated against live chain state: balance changes, approvals granted, reverts. Observed, not guessed.

03

One plain-English verdict

SAFE / CAUTION / DANGER, with a headline a non-technical person understands.

Never signs · holds no keys Stateless · nothing persisted Private · calldata never leaves for third-party scanners Honest · reports simulated vs decoded mode
