Bitcoin PSBT Signing Tool

How to Use This Tool ▼
This signing tool works with TLB_Pocket_Minter, a Telegram bot for minting BRC-20 tokens and managing Bitcoin transactions.
Steps
1. Upload the JSON file from the bot, or paste PSBT directly (hex or base64).
2. Connect your UniSat wallet (extension or mobile app).
3. Review transaction details, sign, and broadcast.
For Airdrops: Sign with the source address (holds the BRC-20 inscriptions), not your minting address.

PSBTs are chain-agnostic; choose the mempool/chain you signed for.

🔍 Decode any PSBT

Paste a PSBT (hex or base64) to decode and inspect: inputs, outputs, scripts, opcodes, sighash, BIP32 paths, and more. Fully client-side — no data sent to any server.

✍ BIP-322 Message Signing

Sign any message with your connected wallet. Output is a BIP-322 simple signature (base64), usable for verification by any BIP-322-compatible verifier.
