Manual FRR vs automated · 12-month model

Does automation beat
lazy FRR lending?

Slide your capital and pick an algorithm. We model 12 months of compounding for a Stratum strategy against manual FRR lending — modeled on three years of history, not a guarantee.

Manual line = Simple FRR (lend at the Flash Return Rate); Stratum line = the selected algorithm — both from the same 3-year backtest engine (1,095 days, same fills and fees), compounded monthly. Modeled, not guaranteed. For reference, the current public FRR for USD is 13.59% gross APR right now (Bitfinex snapshot · Jul 10, 2026, 11:05 PM UTC) — one live moment, not the backtest average.

Modeled, not guaranteed. Both curves are projections from a 3-year backtest (1,095 days, hourly Bitfinex candles, tenors 2/7/14/30/60/120d, snapshot 2026-05-29). Stratum is non-custodial and does not remove Bitfinex platform, counterparty, or stablecoin risk. Past performance does not predict future APR. Not financial advice.

Calculator & backtest FAQ

Is this a real backtest or just a rate guess?

Real backtest. Every strategy percentage comes from the Stratum backtest engine run over three years of hourly Bitfinex funding candles (1,095 days), with a per-tenor rate curve, order-fill modeling, early returns, and the 15% platform fee — using the same algorithm defaults the live app uses.

What is the “manual FRR lending” line?

It is the Simple FRR strategy — lend at the market Flash Return Rate and leave it — run through the exact same backtest, window, and fees as every other algorithm. That is the lazy-lending baseline. The small “current FRR” figure in the footnote is just today's live rate for context, not the backtest average. The “Edge vs FRR” tile is how many percentage points the selected algorithm's modeled APR sits above this Simple FRR baseline.

What does “utilization” mean?

The share of your capital that is actually lent out and earning over the backtest — the “is my money working” number. It can sit below 100% because some algorithms rest capital and wait for richer rates, or hold a reserve between loans. A high modeled APR with low utilization means the return came from a smaller slice of your balance.

Is the big percentage daily or yearly?

Yearly. The headline is annualized modeled APR, compounded monthly across the 12 months shown in the chart.

Why are BTC and ETH APR so much lower than USD and USDT?

Those are the real backtested rates per currency. Margin-borrow demand for stablecoins (USD, USDT) is large and steady, so funding pays well; demand to borrow BTC and ETH is far smaller and more episodic, so their funding rates — and modeled APR — are much lower, often near zero. Switch the currency and every number on the page recomputes for that funding book.

Does Stratum guarantee this APR?

No. Funding rates, fills, early returns, fees, platform risk, and liquidity all change. Backtests compare algorithms under historical conditions; they do not guarantee future returns. Not financial advice.
