Deposit sufficient amount of BTC (sBTC for testnet) to help process transactions. An operator is required to stake 1 BTC as a security deposit before processing transactions (the 1 BTC is time-locked and self-custody, kept under operator's address). If an operator is found acting maliciously (e.g. attempting to steal funds), the deposit will be slashed as a penalty. The deposit can be unstaked when the operator chooses to exit. Here's how to deposit and stake:

  1. Deposit Funds

Click the + button next to Total Balance to deposit funds. Wait for around ten minutes for the deposit to be received. To successfully complete the staking, you need at least stake_amount + dust + gas BTC.

Currently for beta testnet, stake_amount is 1 sBTC, so deposit at least 1.00001 sBTC to the address. Since subsequent work requires 12 sBTC, we recommend an operator to deposit at least 13.00001 sBTC initially.

Note: Fiamma Operator is running on Bitcoin Signet during testnet. Please deposit sBTC to continue.

  1. Stake Funds

When the operator's main address has sufficient BTC, click the "Start operator" button. If you haven't staked funds before, an interface will pop up with the Stake button. Click the button to stake 1 BTC and wait for the transaction to be processed:
