How to mint BRC-20 tokens on UniSat? (Inscribe Guide)

Minting BRC-20 Tokens via UniSat Wallet

1. Ensure you have the UniSat Wallet extension installed on Chrome or Edge. Visit unisat.io and download the official wallet. Do not use third-party clones or unofficial versions.

2. Create a new wallet or import an existing one using your 12-word recovery phrase. Store this phrase offline in a secure location — UniSat does not store private keys.

3. Fund your wallet with enough Bitcoin (BTC) to cover inscription fees. BRC-20 minting requires on-chain transaction fees, which fluctuate depending on network congestion.

4. Navigate to the “Inscribe” tab inside the UniSat Wallet interface. Select “BRC-20” from the available inscription types.

5. Enter the token name, ticker symbol, maximum supply, and decimal places. These fields are immutable once inscribed. Double-check spelling and formatting before submission.

Preparing the JSON Data for BRC-20 Deployment

1. BRC-20 tokens rely on JSON-based op_return payloads embedded in Bitcoin transactions. UniSat auto-generates valid JSON when you input parameters correctly.

2. The JSON must conform to the BRC-20 specification: it includes “p”, “op”, “tick”, “max”, and “dec” keys. Example: {“p”:”brc-20″,”op”:”deploy”,”tick”:”ordi”,”max”:”21000000″,”dec”:”18″}.

3. UniSat validates syntax before allowing inscription. If validation fails, the interface displays a red error message indicating which field violates format rules.

4. Avoid special characters in tickers. Only lowercase alphanumeric strings of length 3–6 are accepted by most indexers and explorers.

5. Decimal precision cannot exceed 18. Setting decimals to zero means the token is non-divisible — each unit represents one whole token.

Submitting and Confirming the Inscription Transaction

1. After entering all required fields, click “Next”. UniSat calculates the estimated fee based on current mempool conditions and displays it in BTC.

2. Review the final summary: ticker, supply, decimals, fee amount, and total BTC required. Any discrepancy here may lead to failed inscription or incorrect token behavior.

3. Confirm the transaction inside the wallet. You will be prompted to sign using your private key. This step occurs locally — no data leaves your browser.

4. Once signed, the transaction broadcasts to the Bitcoin network. It appears as a standard BTC transfer with an OP_RETURN output containing the BRC-20 deployment script.

5. Wait for at least one confirmation. Indexers like ordinals.com and unisat.io scan blocks to detect and parse BRC-20 inscriptions. Token metadata becomes visible only after indexing completes.

Verifying Token Deployment on Block Explorers

1. Copy the transaction ID (TXID) shown after broadcast. Paste it into unisat.io/tx/ or ordinals.com/tx/ to view raw inscription data.

2. Look for the inscription output labeled “text/plain” or “application/json”. Clicking it reveals the full BRC-20 deploy payload.

3. Check that the “tick” matches your intended ticker and that “max” reflects the exact supply you specified. Mismatches indicate input errors during creation.

4. Use the UniSat token explorer (unisat.io/brc20) to search for your ticker. If indexed, it shows total supply, holders, transfers, and recent inscriptions tied to that token.

5. A successful deployment does not guarantee liquidity or exchange listings. It only confirms the token exists as a valid BRC-20 inscription on Bitcoin’s blockchain.

Frequently Asked Questions

Q: Can I mint the same BRC-20 ticker twice?A: No. Once a ticker is deployed, any subsequent deployment attempt with identical “tick” value will fail. Indexers treat duplicate ticks as invalid and ignore them.

Q: Why does my newly minted token not appear in the UniSat token list immediately?A: Indexing takes time. Blocks must be fully confirmed and parsed by UniSat’s backend. Delays range from minutes to several hours depending on indexer load and block height.

Q: Is there a way to edit the max supply or decimals after deployment?A: No. BRC-20 is intentionally immutable. The deploy operation writes fixed parameters to the chain. There is no upgrade or governance mechanism built into the standard.

Q: What happens if I send BTC to the wrong address during inscription?A: Transactions are irreversible. If funds go to an incorrect address — including mistyped receiving addresses or accidental sends — recovery is impossible without external cooperation from the recipient.
