A commitment deposit (CD) locks HEAT for a fixed term and earns interest funded by protocol fees (atomic swaps + Hearth CD share) — not by printing tokens.

​
Prerequisite: mint HEAT first

There is no XFG CD path. COLD / Ember_Heat / “lock XFG” flows are deprecated and removed. See Mint HEAT.

​
CD vs staking vs bank CD

Do not call this “staking.”

​
How interest is funded

Yield plumbing is fed by the only two protocol fee streams: Also from atomic swaps: 11% Bonus Vault, 20% Treasury — not paid as base CD pro-rata yield. Mint premium is 0 bps (goes nowhere) and the 0.1% CD creation fee is a donation to @fuegoxfg — neither is protocol revenue.

​
On-chain representation

Creating a CD produces a TransactionOutputCommitment with a real term (block/epoch length), not HEAT_TERM (mint marker). At maturity you spend with a commitment spend that can claim interest validated against fee-pool accounting.
