Solana transaction signature validator
Paste a base58 transaction signature (tx ID) to check whether it's well-formed before pasting it into a dApp or block explorer. Validation runs entirely in your browser — no RPC call, no data sent to a server.
Paste a Solana transaction signature above.
What gets checked?
- Base58 encoding — Solana signatures use base58 (no 0, O, I, or l).
- 64-byte signature — decodes to an Ed25519 signature (not a 32-byte pubkey).
- Length — valid signatures are typically 87–88 characters.
This does not confirm the transaction succeeded on-chain — only that the string is correctly formatted. Use the transaction lookup or a block explorer to verify confirmation and amount.
Signature vs address
| Type | Bytes | Typical length | Use |
|---|---|---|---|
| Wallet / program address | 32 | 32–44 chars | Send SOL here |
| Transaction signature | 64 | 87–88 chars | Look up a confirmed tx |
Confused? Try the address validator for wallet IDs.
