CAT20 Minter
1. Introduction
The CAT20 Minter is a specialized tool for minting CAT20 tokens on the Bitcoin network, specifically designed to integrate with the Fractal Bitcoin (FB) ecosystem. Built to support secure, decentralized token minting, this utility simplifies the complexities involved in the CAT20 protocol and offers a clean interface for users to mint directly from their Taproot-compatible wallets.
2. Key Features
✨ Non-Custodial Design
The CAT20 Minter is fully non-custodial. Users retain full control over their funds at all times. The platform merely constructs the minting transaction; signing and broadcasting happen via the user's own wallet.
✅ Taproot Compatibility
To ensure proper execution on the Bitcoin network, all wallets and receiver addresses must be Taproot-based:
Wallet Address Format: Must begin with
bc1qorbc1pReceiver Address Format: Must begin with
bc1p(Taproot)
🚀 Quick Minting Flow
Connect your Taproot-compatible wallet
Enter your Taproot receiver address (bc1p)
Input the number of mints (up to 25 per batch)
Click Mint
Sign the transaction when prompted by your wallet
Monitor status in the History section
3. Fee Structure
While DotSwap does not charge a platform fee, standard Bitcoin network fees apply. On average, minting costs are approximately 10% of the token's face value. Fees are determined dynamically based on current network conditions.
4. Common Questions
🤔 Why is my minting transaction pending or not visible?
Minting requires scanning available minter UTXOs and constructing transactions under precise conditions. Delays may occur if:
UTXOs are temporarily unavailable
Network congestion is high
Your batch size is near the maximum
Please allow a few minutes for the transaction to finalize.
💸 Is my $FB / wallet safe?
Yes. All minting operations are initiated and signed by the user. The tool does not store or access private keys or user funds.
❓ Is minting guaranteed to succeed?
Due to the nature of the Bitcoin network and CAT20 protocol constraints, 100% success cannot be guaranteed. The tool makes best-effort attempts to complete mints and is continuously being improved for higher success rates and better UX.
5. Conclusion
The CAT20 Minter by DotSwap is a foundational utility for the emerging CAT20 token standard on Bitcoin. Designed for reliability, accessibility, and full self-custody, it enables anyone to engage with CAT20 assets safely and efficiently.
Connect. Mint. Track. Scale. Welcome to the next layer of Bitcoin-native tokenization.
