Seed phrase
Your 25-word seed phrase is the only way to recover your wallet if you lose your wallet file. Anyone who obtains your seed phrase has full control of your funds.
Write your seed phrase on paper. Store it in a physically secure location. Make a second copy and store it separately from the first. Never photograph it. Never type it into any device connected to the internet.
Wallet file
The wallet file (.keys) is AES-encrypted with your password. A strong, unique password protects against an attacker who obtains the file.
Back up your wallet file to:
- An encrypted external drive
- Offline cold storage
Re-backup after every significant transaction, HEAT mint, or HEAT CD creation — the wallet file holds keys and deposit secrets required to spend or mature CDs.
RPC port
The daemon RPC port has no authentication. Restrict it to localhost:
If you need remote RPC access, use an SSH tunnel:
Then connect locally to 127.0.0.1:28080.
Verify addresses before sending
Fuego transactions are irreversible. Before sending any amount:
- Verify the recipient address is exactly 98 characters long
- Verify it starts with lowercase
f
- For large amounts, send a small test amount first and verify receipt
If sending to an alias, resolve it first with /get_alias and verify the returned address matches your expectation.
Deposit secrets (HEAT CDs)
When you create a HEAT commitment deposit, your wallet stores a deposit secret. That secret is required to:
- Withdraw the CD at maturity (principal + interest)
- Transfer the CD before maturity
Historical off-chain STARK-claim workflows for burns are deprecated. HEAT minting uses the on-chain mintHeatV10 path.
Your wallet file contains these secrets. If you lose the wallet file and cannot restore from seed, those CDs can become inaccessible. Back up your wallet file after every HEAT mint and CD creation.
