Fuego is a privacy-first CryptoNote chain (ring signatures, stealth addresses) with a native financial layer: burn XFG to mint HEAT, lock HEAT in Certificates of Deposit for real yield, trade XFG/HEAT on Hearth, and move value across chains with swapXFG atomic swaps.

​
Product path (current)

You cannot lock raw XFG as a CD. COLD deposits, Ember_Heat, and “XFG deposits” are removed. See How CDs work and Mint HEAT.

​
What you can do

Mint HEAT

Burn XFG to mint HEAT at Hearth pool TWAP pricing (mintHeatV10).

HEAT CDs

Term-lock HEAT and earn yield funded by protocol fees.

Hearth

On-chain XFG/HEAT market (AMM + orderbook hybrid).

swapXFG

Cross-chain atomic swaps — no custodian, no CEX.

​
Core properties

Privacy by default. Ring signatures hide senders. Commitment deposits hide principal and interest. No one can read your CD size from the chain alone. Two assets, one bank. XFG is base-layer private money. HEAT is the flatcoin (purchasing-power oriented; peg reference HEAT_PEG_USD = 1.58). CDs are always HEAT. No counterparty for CDs and swaps. CD rules and swap atomicity are consensus / cryptography, not a custodian. Transferable and compoundable. Mature or transferred CDs can roll over so principal + interest re-locks as a new HEAT CD.

​
Fee structure (from live constants)

Source: src/CryptoNoteConfig.h. These are separate mechanisms. Atomic-swap fees are not the same stream as Hearth LP fees. DIGM (if enabled elsewhere) uses its own fee constants and is not core Fuego onboarding.

Dual-asset model
