# Mint HEAT

> Burn XFG to mint HEAT via mintHeatV10 and Hearth TWAP pricing.

Minting HEAT is **step 1** of the deposit architecture. Step 2 (optional) is locking HEAT as a CD.

## Prerequisites

* Synced `fuegod` (or testnet daemon)
* Wallet with spendable **XFG**
* Hearth pool available for pricing (TWAP / spot)

## Wallet path

Use the wallet mint path (`mintHeatV10`), **not** `createDeposit` with a normal CD term for minting.

`createDeposit(term = HEAT_TERM)` is the burn/mint term marker (`0xFFFFFFFF`). Term-locked CDs use **real epoch/block terms** and require **already-minted HEAT**.

### Conceptual flow

```
Wallet: mintHeatV10(xfg_amount)
    → burns XFG
    → prices HEAT from Hearth TWAP
    → credits HEAT commitment outputs to your wallet
```

CLI / TUI surfaces expose this as **Burn2Mint** / **HEAT mint** (names vary by tool). Prefer the wallet method that calls `mintHeatV10` rather than legacy `cold` commands.

## Pricing

| Source       | Role                                            |
| ------------ | ----------------------------------------------- |
| Hearth TWAP  | Preferred mint rate (XFG per HEAT, fixed-point) |
| Hearth spot  | Fallback if TWAP unavailable                    |
| Legacy 10M:1 | **Display/legacy only** — not mint pricing      |

## After minting

1. Confirm HEAT balance in the wallet.
2. Optionally open a [HEAT CD](/features/commitment-deposits/creating-deposits).
3. Or trade on [Hearth](/features/hearth/how-hearth-works).

## Deprecated paths (do not use as primary docs)

* STARK-only “burn on Fuego → claim HEAT on Ethereum” as the **only** mint story
* COLD / Ember\_Heat forever-deposits
* Treating `convertXfgToHeat()` as mint

Historical burn notes may live under deprecated folders; they are **not** the default product path.

## RPC / metrics

Nodes may expose HEAT metrics (e.g. `/heat_metrics`) for supply and pool-related stats. Exact RPC names depend on your build — prefer wallet mint methods over raw crafting unless you are a protocol developer.
