Creating a HEAT CD

Prerequisites

Synced daemon
Wallet with HEAT balance (mint first — Mint HEAT)
Enough balance for the CD amount + network fee

Critical rule

Action	Asset	Term
Mint HEAT	Burn XFG	`HEAT_TERM` / `mintHeatV10`
Open CD	Lock HEAT	Real term (6–72 epochs on mainnet)

createDeposit with a normal term is for HEAT CDs. Do not use legacy cold / COLD commands as the product path.

Create a CD

Exact CLI names depend on wallet build. Conceptual:

# After HEAT is in the wallet:
deposit <heat_amount> <term_epochs>

Term bounds (mainnet): 6–72 epochs (CD_MIN_EPOCHS … CD_MAX_EPOCHS). Testnet allows shorter minimums for testing. Example pattern — lock HEAT for the minimum term:

deposit 10 6

Confirm the wallet reports a HEAT CD (not a burn/mint and not COLD).

What happens on-chain

Output: TransactionOutputCommitment for HEAT
Amount hidden under commitment
Maturity height = creation height + term blocks
Deposit secret stored in your wallet file — back it up

Verify

Use wallet list/info commands for deposits (avoid relying on deprecated list_cold / cold_info naming in older docs — if still present in a binary, they may be legacy aliases). RPC: see Deposits API.

Estimate yield

curl -X POST http://127.0.0.1:28080/estimate_cd_yield \
  -H 'Content-Type: application/json' \
  -d '{"amount": 100000000, "creation_height": 0}'

Amounts are in atomic units where 1 coin = 10,000,000 atomic (COIN = 1e7), not 1e9.

Testnet

Testnet epochs are 10 blocks. Use testnet to practice mint → CD → maturity → withdraw before mainnet.
