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

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

​
After minting

  1. Confirm HEAT balance in the wallet.
  2. Optionally open a HEAT CD.
  3. Or trade on Hearth.

​
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.
