Put your USDT
to work.
Connect your own funding-only API key. We run our portfolio strategy — diversified across short/mid/long/x-long, smart per-period floor, and rate-spike GRAB mode. Integrates with the public funding-market rates. Your principal stays in your own exchange account. We can't touch it.
Three steps, five minutes
No code to write, nothing to run outside your exchange account.
1 · Sign in with Google
No password to remember, no card on file. One-tap Google sign-in.
2 · Paste a funding-only 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.
5.5-year walk-forward backtest
58 OOS windows of 90 days each, rolling forward across 2020-11 → 2026-04 with realistic fill model (transient-spike filter, prepayment hazard, depth gating). Values below are 70% of the walk-forward median for marketing-conservative consistency.
Above values are 70% of backtest medians (2026 data + 5.5y walk-forward). Raw medians: 17.8%–32.9% depending on symbol/regime, net of the platform's 15% fee. **Backtest is based on 2020-11 → 2026-04 historical data and does NOT guarantee future returns**; market regime shifts and rate ranges change, and live results may run higher or lower. Recommend the 7-day free trial to see your wallet's actual numbers before committing.
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, tuned per symbol: fUSD balanced 6/8/12/15% (catches frequent fUSD spikes), fUST balanced 4/5/7/9% (matched to fUST's lower volatility regime). When the market cools, the bot pauses instead of locking funds at bad rates.
GRAB rate spikes
When market rate sustainably climbs to 15% / 20% / 30% APR, the bot deploys part of the reserve (10-30%) proportionally. Transient sub-minute spikes that the 60s tick can't realistically catch are filtered out.
Lending happens inside your own exchange account
This isn't a custodial platform. We only execute API actions you authorize.
Funds
All USDT and interest accrue directly in your own exchange 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.
Simple, transparent pricing
Two plans. Switch any time. No lock-in, no commitment.

Can you touch my funds?
No. We only call the funding API you authorized; the API key has funding read+write only, no withdraw permission. All USDT and accrued interest stay in your own exchange account.
Why Bitfinex Funding and not Binance / OKX?
That platform's funding market 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 the returns.
Can the bot really hit 12–14% APY?
The hero 12-14% is 70% of the 5.5-year walk-forward median for marketing conservatism. The raw walk-forward median is 17.8-19.4% net (after the 15% platform fee, across 58 OOS windows). But annual rate environments shift — USDT funding APR ranged 4-25% over the last 5.5 years, and we do NOT guarantee future returns. Run the 7-day trial first to watch your own wallet's actual numbers.
Do you take a cut of the interest?
Zero. We never take a percentage of your earnings. Just a 60 USDT / year subscription, or 30 USDT / year forever if you signed up to the exchange via our refcode (plus members-only events). Our incentive is fully aligned with you.
What if Yieldsforge shuts down?
Your money stays in your own exchange account regardless of us. Even if we vanish tomorrow, your existing credits run to maturity and principal+interest land in your wallet, untouched.
Can I stop any time?
Yes. Delete your account in settings, or simply revoke the API key in your exchange dashboard. 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 the funding market well — can I still use this?
Yieldsforge handles every strategic decision. You just need USDT in your funding wallet, an API key, and a chosen preset. We have a step-by-step API key tutorial.
