Minting Cashu Token

The process of swapping sats for Cashu token is called "minting". To mint with Coco you prepare a mint operation, specifying a mintUrl and an amount in sats.

Before minting, ensure the mint is added and trusted (see Adding a Mint):

// Add and trust the mint first
await coco.mint.addMint('https://minturl.com', { trusted: true });

// Create a mint operation (this also creates the remote quote)
const pendingMint = await coco.ops.mint.prepare({
  mintUrl: 'https://minturl.com',
  amount: 21,
  method: 'bolt11',
  methodData: {},
});

The returned pending mint operation has a request field containing the BOLT11 payment request that needs to be paid before minting can happen. When Watchers and Processors are activated (they are by default) Coco will automatically check whether the quote has been paid and redeem it automatically. You can also execute the pending operation yourself after payment.

const pendingMint = await coco.ops.mint.prepare({
  mintUrl: 'https://minturl.com',
  amount: 21,
  method: 'bolt11',
  methodData: {},
});

console.log('pay this: ', pendingMint.request);
console.log('this is the quote id: ', pendingMint.quoteId);

coco.on('mint-op:finalized', (payload) => {
  if (payload.operationId === pendingMint.id) {
    console.log('This was paid!!');
  }
});
