# Review a transaction

WalletChan uses one decision structure across dapps, WalletConnect, Send,
staking, swaps, permission revocation, replacements, and privacy operations.

## Read from top to bottom

1. **Requester and action**: exact site or WalletChan feature, plain-language
   action, contract or recipient.
2. **Estimated changes**: likely tokens/NFTs sent or received and changed
   approvals.
3. **Request context**: signer, network, warnings, and route-specific details.
4. **Advanced**: decoded/raw calldata, nonce, gas internals, hashes, and
   technical metadata.
5. **Commitment**: pinned signer, fee decision, Reject, and Confirm.

## Request queue

When several prompts exist, use next/previous and the counter. **Reject all**
applies to the displayed queue scope. Back or closing the surface does not
reject a request; requests have no automatic age timeout.

## Signer and chain pinning

The account and chain shown are part of the request. Switching the wallet
elsewhere cannot redirect it to another signer. A signer mismatch causes
rejection rather than an invisible substitution.

## Simulation and warnings

WalletChan may show loading, successful estimated changes, likely revert,
unavailable simulation, malformed calldata, risky approval, suspicious origin,
or balance/fee warnings. A likely revert is blocked by default and requires a
separate acknowledgement before deliberate continuation, if continuation is
allowed.

## Account differences

| Account | Final action |
| --- | --- |
| Private key | Local sign-once and broadcast |
| Seed phrase | Local derived-key sign-once and broadcast |
| Ledger | Hardware review and approval; mutable controls lock while waiting |
| View-only | Reject-only unless exact developer impersonation RPC is enabled |
| Safe | Create/approve/execute a Safe proposal instead of EOA signing |
| Bankr | Remote signing/submission; Bankr manages gas |

## Reject if unsure

WalletChan cannot undo a confirmed onchain transaction. Reject and verify the
site, recipient, amount, chain, asset changes, approval limits, and fee before
trying again.
