Lending on Bitfinex used to require a $99/mo bot and a leap of faith. Both can go.
Bitfinex Pro is gone.
Bitfinex retired Margin Funding Pro. The dashboard whales relied on for the last seven years no longer exists. We rebuilt it, better.
Percentage fees get heavy.
On $500K deployed at an illustrative 10% APR, a 5% earnings cut is about $2,500/year. Stratum uses flat pricing, so more upside stays with you.
Reports should trace back to Bitfinex.
Stratum builds earnings reports from Bitfinex funding ledger events, so credits, fees, currencies, and exports are easier to reconcile.
Eleven strategies, backtested.
From a lazy "place all at FRR" baseline to volatility-aware adaptive spreads and rate-forecasting lockers. Every strategy backtests against real historical funding data — modeled, not a guarantee.
Simple FRR
Place all capital at FRR. The lazy baseline.
Rate Spread
Tiered offers above and below FRR. Captures the spread.
Maturity Ladder
Spread loans across 2/7/14/30-day buckets.
Adaptive Spread
Volatility-aware spread that widens when the rate gets choppy.
Yield Curve
Lend where the funding term structure pays most.
Adaptive Carry
Locks long when the rate is high in its own recent range; stays liquid when low.
The edge is strategy selection, not bookkeeping.
Correct exports matter, but they are table stakes. Stratum's engine watches rate regimes, tenor curves, fill behavior, and idle capital, then decides when to stay liquid, ladder out, or lock a longer term.
Backtests replay real Bitfinex funding history with fee drag and fill modeling, so you can compare custom algorithms before they touch live offers. Modeled results are for strategy comparison, not return promises.
Flat fees. Never a cut of earnings.

We never touch your money.
Stratum connects to Bitfinex via API keys that you create with withdraw permissions disabled. Our service can read your balances and place funding offers. It cannot move your funds anywhere.
Risks we don't mitigate, and won't pretend to: Bitfinex insolvency, stablecoin depeg, strategies losing principal during black swans. Read the risk page before you start.
