HEAT Certificates of Deposit (CDs)

CDs lock HEAT, not XFG. You must mint HEAT first (mintHeatV10), then open a term-locked HEAT CD.
CD yield is variable and not guaranteed. Interest depends on protocol fee volume (swapXFG atomic swaps and Hearth trades). Low activity periods can mean very low or zero yield.
Lock-up risk. Your HEAT is inaccessible until the maturity height. You cannot withdraw early. Liquidity before maturity requires transferring the CD, typically at a negotiated discount. Interest rate risk. You lock a term, not a fixed APY. If fee volume falls after you lock, you earn less than expected. Consensus risk. CD rules are enforced by Fuego consensus. A consensus bug could affect deposits. Rules are open source — review them before locking significant amounts. Wrong model. There is no current product path that locks XFG as a CD. COLD / Ember_Heat / “XFG deposit” models are removed.

​
swapXFG (atomic swaps)

Counterparty stall. If the counterparty goes offline mid-swap, wait for the timelock, then refund. Funds are delayed, not forfeited, if you follow the refund path. Timelock duration. Depends on the counterparty chain and daemon config. Check your pair’s docs before large swaps. No on-protocol price protection. You and the counterparty agree amount/rate off-chain (or via offers). Market moves between agreement and completion do not auto-adjust the deal. Fee. Completed XFG-side swaps charge 1%, routed 69% CD yield / 11% Bonus Vault / 20% Treasury (CryptoNoteConfig.h).

​
Hearth liquidity

Hearth is the on-chain XFG/HEAT market. Protocol trade fee is 1% (HEARTH_FEE_BPS = 100), 100% → CD yield accumulator in consensus code. LPs earn the swap spread, not the fee.
Providing Hearth liquidity carries impermanent loss risk. If the XFG/HEAT pool price moves sharply while you are an LP, you may withdraw less value than you deposited, even after LP fee income.
Impermanent loss. Inherent to AMM-style inventory. Large adverse moves can dominate spread income. Do not treat the old “0.3% LP fee” figure as Hearth’s protocol trade fee — that number is not HEARTH_FEE_BPS. Consensus risk. Pool mechanics are on-chain. Review How Hearth works before large LP deposits.

​
HEAT mint (burn XFG)

Minting HEAT burns XFG permanently. Burned XFG is not withdrawable as XFG. There is no recovery of the burned principal.
Permanent reduction of XFG. You exchange XFG for HEAT at Hearth TWAP pricing via mintHeatV10. HEAT value and future CD yield are not a guaranteed recovery of burned XFG market value. Wallet backup. Keep seed + wallet file backups before minting and before opening CDs. Deposit secrets and keys live in the wallet. Historical note (not the primary path). Older STARK / off-chain claim flows and COLDAO-era language are deprecated product narrative. Do not treat “generate a STARK proof to claim HEAT elsewhere” as the current default mint path.

​
General

No reversals. Confirmed sends, mints, CD ops, Hearth trades, and swaps are irreversible. Privacy is probabilistic. Ring signatures and commitments provide strong privacy, not absolute anonymity under all behavioral analysis.

Known issue — block-serving RPC hang

Every daemon binary tested — including the month-old Jul-10 daemon on port 18180, while idle and fully synced — hangs on queryblockslite.bin, queryblocks.bin, and getblocks.bin. This blocks live sync/send end-to-end testing only. All protocol verification is performed against the C++ production code directly (unit and integration harnesses), not live RPC.
