Agent Wallet ↗
plaintext-wallet · self-hosted

Before you sign,
know what you're signing.

Check a real wallet's approvals, or try a sample scenario — either way, get a plain-language explanation of what each permission actually does.

3 free checks a day $0.03 explain a signature $0.04 wallet check

For agents and developers: the verdicts come from presign-guard (the same checks and a signed receipt); PlainText adds the explanation in plain language. If you only need the verdict and reason codes, call presign-guard directly: GET /v1/approvals?chain=base&address=… ($0.02) or POST /v1/check ($0.01).

Wallet address
No wallet connected. You only need one to pay; the free checks work without.

3 free checks a day, no wallet needed.
