What happened in
this transaction?

Every payment and trade on Solana is public, but written in code. Paste one in and Docent tells you what happened, in plain English.

A signature is a transaction's ID. Find one in your wallet's activity or on explorer.solana.com.

New: check a transaction before you sign it

When an app asks your wallet to sign something, paste that transaction here first. Docent does a dry run and tells you what it would do, and warns you if it looks like a scam.
