We automatically check the permissions to confirm the key can't withdraw.
Choose a lending style and the bot follows that pace for you.
Steady
Lower rate, but your money rarely sits idle
Balanced
Mixes rate and idle time — good for beginners
Bold
Waits for higher rates; money may sit idle sometimes
See how much interest the bot earned for you, every day.
Interest compounds automatically at 01:30 UTC and keeps growing.
IBRR
Finds the Best Rate, Automatically
Checks the market rate board every 60 seconds. Finds the highest rate that fills fast, and gets there first.
GRID
Splits Your Money Into 3 Parts
60% lends right away at the best rate. 30% waits for small spikes. 10% waits for big spikes.
COMPOUND
Yesterday's Interest Earns Interest Today
At 1:30 AM UTC daily, the bot instantly relends your interest along with your principal.
Read + Funding Only
Only reads data and lends — it can never withdraw or trade.
AES-256-GCM Encryption
Your key is encrypted and only unlocked when the bot runs.
IP Whitelist
Only our fixed IP can use your key.
2-Step Verification
Required for every login, to keep your account safe.
Do I need to allow withdraw or trading?
No. We only need Read and Funding permissions. Keys with withdraw or trading access are rejected — your money can never be moved.
What's the minimum amount to start?
Bitfinex requires at least $150 per lend. We recommend $500 or more so the 3-part grid has room to work.
Which currencies are supported?
USD, USDT, BTC, and ETH. Each one runs its own strategy independently.
Can I customize the lending period?
Bitfinex allows 2 to 120 days. We default to 2 days for flexibility — Pro Mode lets you customize each layer.
How does auto-compounding work?
At 1:30 AM UTC daily, once interest settles, the bot instantly relends your principal plus the new interest.
Can I cancel anytime?
Yes. Your bot keeps running until the current period ends. Your Bitfinex account and funds are never affected.
