Context
Use before signing an unfamiliar transaction, or to understand one after the fact.
Prompt
Explain this transaction in plain language, then assess its risk.

TRANSACTION
Chain + hash: [DATA]
Decoded calls / method: [DATA]
Contracts touched: [DATA]
Token movements: [DATA]
Approvals granted: [DATA]

Output:
1. What this transaction did, in two sentences a non-developer understands.
2. Every permission it granted, and whether each is bounded or unlimited and time-limited or permanent.
3. Residual risk after the transaction (standing approvals, delegated authority, position exposure).
4. Anything unusual: unexpected contracts, hidden transfers, non-obvious recipients.
5. Concrete cleanup actions, if any (revoke, reduce allowance, move funds).

If the decoded data is insufficient to be certain, say so explicitly.
Example Output
It swapped 5,000 USDC for TOKEN through an aggregator router, routed via two pools. Permissions: an unlimited, permanent USDC allowance to the router. Residual risk: that allowance stays open indefinitely and remains exploitable if the router is upgraded maliciously. Unusual: none. Cleanup: reduce the allowance to zero now that the swap is complete.

What output should I expect?

It swapped 5,000 USDC for TOKEN through an aggregator router, routed via two pools. Permissions: an unlimited, permanent USDC allowance to the router. Residual risk: that allowance stays open indefinitely and remains exploitable if the router is upgraded maliciously. Unusual: none. Cleanup: reduce t.

The vocabulary this page depends on.

  • Smart Contract

    A smart contract is code deployed to a blockchain that executes deterministically when called, holding balances and enforcing rules without an operator.

  • Gas Fee

    A gas fee is the network payment for computation and storage in a transaction, priced by demand rather than by trade size.

  • Token Approval

    A token approval grants a contract permission to move your tokens — persistent, often unlimited, and the most common source of avoidable losses.

  • Bridge

    A bridge moves value between blockchains by locking or burning on one side and issuing a representation on the other.

Related use cases

How people apply it, and what came out.

  • Monitor Wallet Transactions

    Alerting on the user's own wallet activity caught an unauthorised approval attempt and forced an approval cleanup that removed 14 standing allowances.

  • Automate Repetitive Web3 Actions

    Automating reward claims and gas top-ups with session keys and spend caps saved about 5 hours per month with no unbounded authority.

Comparisons & alternatives

Pick between the options.

  • Rabby vs OKX Web3 Wallet

    Rabby is the safety-focused EVM wallet with pre-transaction simulation; OKX Web3 Wallet trades some of that depth for multi-chain breadth and built-in trading.

  • Hot Wallet vs Cold Wallet

    Hot wallets trade convenience for exposure; cold wallets trade friction for a signing key that never touches an internet-connected device.

  • Smart Money vs Technical Analysis

    Smart money tracking reads who is positioning; technical analysis reads how price behaves. They answer different questions and fail differently.

  • Web2 Apps vs Web3 Apps

    Web2 apps authenticate with accounts and store state on private servers; Web3 apps authenticate with a wallet signature and keep state on a public chain.
