Put your USDT
to work.
Connect your own Bitfinex funding API key. We run our portfolio strategy — diversified across short/mid/long/x-long, smart per-period floor, and rate-spike GRAB mode. Your principal stays in your Bitfinex account. We can't touch it.
Three steps, five minutes
No code to write, nothing to run outside Bitfinex.
1 · Sign in with Google
No password to remember, no card on file. One-tap Google sign-in.
2 · Paste a Bitfinex API key
Create a funding-only key (no withdraw permission). We Fernet-encrypt it at rest and only decrypt during a worker tick.
3 · Pick a preset, bot runs
Aggressive / Balanced / Safe — three backtested defaults, switch any time. The bot evaluates every 60 seconds.
Historical backtest
Two years of real Bitfinex funding candles (Apr 2024 → Apr 2026), conservative fill model.
Backtest uses a conservative fill model (a fill counts only when the hourly candle low ≥ our offer rate within 24h). Live results typically run slightly higher. Past performance does not guarantee future results.
Portfolio strategy on autopilot
Stop chasing single high-rate offers. Multi-bucket diversification keeps you out of long-term locks at low rates.
4-bucket spread
Short (2d) / Mid (7d) / Long (30d) / X-long (120d) auto-filled to your target ratios so no single fill freezes your wallet.
Per-period floor
Each period has its own floor: short 4% / mid 6% / long 9% / x-long 12%. When the market cools, the bot pauses instead of locking funds at bad rates.
GRAB rate spikes
When market rate spikes to 20% / 30% / 60% APR, GRAB mode commits all capital to the longest period. Backtests show these add 5pp+ to APY.
Lending happens inside your Bitfinex account
This isn't a custodial platform. We only execute API actions you authorize.
Funds
All USDT and interest accrue directly in your Bitfinex account. We can't withdraw, transfer, or receive any funds.
API key
Create the key with funding read+write only — do NOT enable withdraw. We auto-verify and reject any key with withdraw permission.

Can you touch my funds?
No. We only call the Bitfinex funding API you authorized; the API key has funding read+write only, no withdraw permission. All USDT and accrued interest stay in your Bitfinex account.
Why Bitfinex and not Binance / OKX?
Bitfinex Funding has the deepest liquidity, the highest rate volatility, and the most open API. The same strategy on Binance/OKX either can't deploy or yields a fraction of Bitfinex's returns.
Can the bot really hit 8–10% APY?
The backtest uses a conservative fill model; live tends to run slightly higher. But annual rate environments shift — USDT funding APR ranged 5–15% over the last 2 years. Run the 7-day trial and watch your own wallet's numbers before committing.
Do you take a cut of the interest?
Zero. We never take a percentage of your earnings. Only the 30 USDT / year subscription (or free if you signed up to Bitfinex via our referral). Our incentive is fully aligned with you.
What if Yieldsforge shuts down?
Your money stays in your Bitfinex account regardless of us. Even if we vanish tomorrow, your existing credits run to maturity and principal+interest land in your Bitfinex wallet, untouched.
Can I stop any time?
Yes. Delete your account in settings, or simply revoke the API key in Bitfinex. Already-lent credits run to natural maturity and return to your account.
Which currencies do you support?
Today: USDT (fUST) + USD (fUSD). USDC and other funding pairs are on the roadmap.
I don't know Bitfinex Funding well — can I still use this?
Yieldsforge handles every strategic decision. You just need USDT in your Bitfinex Funding wallet, an API key, and a chosen preset. We have a step-by-step API key tutorial.
