+# Melting Proofs
+
+**Melting** is the reverse of [minting](minting.md). It involves paying [Proofs](https://github.com/cashubtc/nuts/blob/main/00.md#proof) back to the mint to settle an external Lightning invoice. This process consists of three steps:
+
+1. Request a melt quote for the invoice.
+2. Submit the required Proofs (including a fee reserve, if applicable).
+3. Confirm whether the invoice was paid and collect any change.
+
+:::warning
+Mints only refund overpaid fees. To ensure your inputs match the required amount, use `CashuWallet.send()` beforehand to swap Proofs as needed.
+:::
+
+```ts
+const quote = await wallet.createMeltQuote(mintQuote.request);
+const fee = quote.fee_reserve;
+
+const {keep, send} = await wallet.send(10, proofs});
+
+const response = await wallet.meltProofs(quote, send);
+```
+
+## Fee Reserve and Change
+
+Mints may include a fee reserve to cover anticipated Lightning fees. The `cashu-ts` library automatically appends [blank outputs](https://github.com/cashubtc/nuts/blob/main/08.md) to the melt request and mints new Proofs if change is returned.
+
+## Options
+
+`meltProofs` accepts a range of options to control the shape of the minted Proofs. Check out the [API Reference](https://github.com/cashubtc/cashu-ts/blob/main/src/CashuWallet.ts) for more information

 # Minting Proofs
 
-**Minting** is the operation of making a Lightning payment to the mint to receive some [Proofs](https://github.com/cashubtc/nuts/blob/main/00.md#proof) in return.
