Mint

1) Default BOLT11 mint (policy outputs)

const newProofs = await wallet.ops
	.mintBolt11(100, quote) // quote: string | MintQuoteBolt11Response
	.run();
Copy

2) Two-step BOLT11 mint with prepare()

const preview = await wallet.ops.mintBolt11(100, quote).asDeterministic(0).prepare();

// Persist `preview` if you want to retry safely later.
const newProofs = await wallet.completeMint(preview);
Copy

• prepare() builds the exact mint payload without calling the mint yet.
• run() is equivalent to const preview = await prepare(); await wallet.completeMint(preview).

3) Deterministic mint with keyset + callback

const newProofs = await wallet.ops
	.mintBolt11(250, quote)
	.asDeterministic(0, [128, 64]) // counter=0 => auto-reserve, split must include denoms
	.keyset('0123456')
	.onCountersReserved((info) => console.log(info))
	.run();
Copy

4) Locked BOLT11 quote signing

// Create a locked mint quote
const pubkey = '02...'; // Your public key
const quote = await wallet.createLockedMintQuote(64, pubkey);

// Sign and mint
const newProofs = await wallet.ops
	.mintBolt11(50, quote)
	.privkey('user-secret-key') // sign locked mint quote
	.run();
Copy

5) Two-step BOLT12 mint

const quote12 = await wallet.createMintQuoteBolt12(pubkeyHex, { amount: 64 });
// pay the BOLT12 offer, then refresh the quote...
const updatedQuote = await wallet.checkMintQuoteBolt12(quote12.quote);
const availableAmount = updatedQuote.amount_paid.subtract(updatedQuote.amount_issued);

const preview = await wallet.ops
	.mintBolt12(availableAmount, updatedQuote)
	.privkey(privkeyHex)
	.asRandom([32, 16, 16])
	.prepare();

const newProofs = await wallet.completeMint(preview);
Copy

• BOLT12 always requires the full quote object and .privkey(...).
• For custom payment methods (e.g., BACS, SWIFT), use the generic wallet methods directly: wallet.createMintQuote(method, ...), wallet.checkMintQuote(method, ...), wallet.mintProofs(method, ...), or the two-step wallet.prepareMint(method, ...) / wallet.completeMint(...). See Mint Token – Custom Methods for examples.
