In each cycle, most advertised “yield” emissions, transient basis/funding trades, or leverage‑amplified carry that disappears when incentives or market structure shift. By contrast, real BTC yield is BTC‑denominated cash flow sourced from ongoing transaction activity, net of financing and control costs.
@yieldbasis introduces a new AMM design to generate sustainable BTC yields in the range of 9%–60%, while eliminating impermanent loss. Its mission is to unlock on-chain BTC liquidity by turning BTC into a productive asset.
Unlike traditional AMMs, where impermanent loss often outweighs trading fees, making spot BTC the better choice unless heavy incentives are offered.
YieldBasis restructures LP exposure so BTC can earn yield efficiently without relying on subsidies.
Yield Basis (YB) targets that standard via an AMM that:
Ii) linearizes LP exposure to track BTC price linearly via compounding leverage, where exposure adjusts automatically with price, thereby reducing impermanent loss. If BTC rises, your exposure increases (holding more BTC), If BTC falls, your exposure decreases (you’re holding less).
(ii) budgets rebalancing with a dedicated stream funded by 50% of pool fees plus the protocol’s borrow cost, so liquidity can be kept near the peak even through price drifts.
Formally, the operating identity is: APR ≈ 2×(pool fees) − (borrow rate + re‑leverage loss); scalability therefore requires that arbitrage/user flow keeps gross fees above the combined financing and repositioning costs.
Empirically, the team’s backtests report an average ~20% BTC APR over 2019–2024 (with regime spikes, e.g., ~60% in 2021), consistent with periods when CEX↔DEX price dislocations and retail flow were abundant. These results are model‑based and path‑dependent; realized outcomes will vary with volatility, market depth, and routing share, and are sensitive to tail scenarios (e.g., sharp BTC drawdowns triggering unwind, or a crvUSD peg disturbance hitting both legs simultaneously, even with circuit breakers).
The remainder of this article evaluates:
(1) why BTC yield remains scarce despite headline APRs (denomination, capacity, and persistence constraints),
(2) what is differentiated in YB’s mechanism (IL mitigation via compounding leverage plus a funded rebalance budget),
(3) the underwriting checklist (stress behavior, budget sufficiency, venue depth/router share, wrapper and stablecoin risk, governance incentives), and
(4) conditions for infrastructure‑scale adoption if live data confirm backtests across multiple volatility regimes.
Why BTC yield is still mostly a mirage
The BTC yield market today fragments into six “original” sources:
quant trading
DEX LP
Lending
staking (via Babylon)
collateral mining
plus LSTs and Pendle‑style yield tokenization.
In practice, much of the headline APR is paid in altcoins or requires leverage to matter.
Here is an article by@ruiixyz that details how each type of yield sources. https://x.com/ruiixyz/status/1904637841608409095
She summarizes it crisply:
BTC lending is ~0.02–0.5% APR;
DEX LP can print 6–60% but is capped by IL;
collateral/TvL mining and LST stacks skew to altcoin‑denominated rewards and liquidity risk.
The BTC Yield Landscape diagram shows the structural opportunity:
~2M BTC sits in CeFi
~245k BTC in DeFi, with wrapped flavors spread across Ethereum and L2s.
Whoever builds the deepest, IL‑tolerant BTC↔stable venue on‑chain will intermediate CEX↔DEX flow and unlock real basis yield at scale.
Most yields you see are (a) paid in something other than BTC, (b) capacity‑limited, or (c) borrowed from the future via emissions.
The result: big APR screenshots, thin persistent cash flow. A quick mental model we use on the investing side is five tests, denomination, provenance, persistence, capacity, and concentration. Most BTC “yields” fail at least two.
Where the mirage comes from
Denomination mismatch. You deposit BTC but get rewarded in an altcoin (or points). If the reward asset sells off, your “APR” evaporates even if operations don’t change. The BTC Yield Sources table highlights that staking, collateral mining, LSTs, and Pendle flows are largely altcoin‑denominated rather than true BTC income.
Basis trades with cliff‑edge risk. Quant/basis strategies can be real yield, but they’re zero‑sum, infra‑heavy, and shrink as more capital crowds in. The write‑up notes market‑neutral targets (e.g., ~4–8% BTC APR) but with meaningful execution and stop‑loss risk; only scarce, elite teams can consistently print above that.
Impermanent loss (IL) hiding in plain sight. DEX LP fees look juicy (6–60%), but IL usually overwhelms fees over a full cycle; simply holding BTC often outperforms. Hence only ~3% of wrapped BTC sits in DEX LPs today, supply is constrained because LPs learn this the hard way.
Borrow‑to‑farm math. BTC lending rates are low (~0.02–0.5% APR), so most “looping” plays require leverage or cross‑asset risk to matter. That’s not free carry; it’s a convex bet that can unwind quickly.
Reflexive emissions. LST stacks and yield tokenization platforms amplify returns by layering alt incentives (including their own token), which cuts both ways: it works…until it doesn’t. Pendle participation itself is sensitive to $PENDLE price and underlying yield volatility.
What each “original” source really offers (and why most don’t scale)
Quant trading (funding, basis, cross‑venue arb).
Real, but scarce. Needs top‑tier infra (latency, custody routes, borrow lines) and mostly harvests CeFi/TradFi liquidity, still where most depth lives. Capacity saturates, and returns compress as capital shows up.DEX LP.
Fees are visible; IL is not. Net PnL is path‑dependent and typically loses to spot in trending markets. That’s why BTC LP supply remains thin despite the fee screenshots.DEX TVL data shows that while DeFi has recovered from the post-DeFi summer lull and returned to all-time highs, DEX liquidity has largely stagnated, likely because the risk of impermanent loss continues to deter liquidity providers
Lending.
BTC is collateral to borrow stables; borrow demand is the bottleneck. Hence ~0.02–0.5% APR for lenders in both CeFi and DeFi—solid plumbing, not a yield business.Staking (via Babylon).
Interesting security primitive but rewards are altcoin‑denominated and not yet proven at scale; risk sits in protocol launch/execution and token economics.Collateral/TVL mining.
Emissions for parking BTC. Works while incentives are rich; dilutes as TVL grows and usually pays in volatile tokens.
On top:
LSTs (Lombard, Pump, etc.). Mixed strategies, cross‑chain wrappers, heavy on alt incentives; low liquidity creates liquidation cascades in stress.
Yield tokenization (Pendle). Powerful rails to trade yield, but it’s only as “real” as the upstream yield, again, mostly alt‑denominated and reflexive today.
What Yield Basis is trying to solve (and how)
LP PnL on constant‑product curves scales with √price, which creates IL vs. spot.
Why does deposit value in an AMM scale with √price?
Deposit value scales with √price because of how AMMs rebalance positions.
As the price of your asset rises, the AMM gradually sells portions of your holdings into the counter-asset. When the price falls, it does the opposite, buying more of your asset as it gets cheaper. This continuous rebalancing means your portfolio’s value grows in proportion to the square root of the price, not linearly with the price itself.
An explainer below
1. The Setup:
In a constant product AMM (x·y = k), your deposit is split between two assets (say ETH + USDC).
As prices move, the AMM automatically rebalances your position.
2. Price Goes Up 📈
The AMM sells some of your ETH into USDC.
You end up holding less ETH, more USDC.
Gains are muted compared to just holding ETH.
3. Price Goes Down 📉
The AMM buys ETH with USDC.
You end up with more ETH, less USDC.
Losses are softened compared to just holding ETH.
4. The √Price Effect
Because the AMM is constantly selling into strength and buying into weakness, your portfolio’s value doesn’t move linearly with price.
Instead, it follows the square root of price curve, smoother, slower growth on the upside, cushioned decline on the downside.
Blue = HODL (linear with price).
Orange = LP position (√price curve).
Green = flat line of USDC only.)
Eliminating IL with Leverage
If you compound‑leverage the LP so that the loan value is continuously maintained at ~50% of collateral, the portfolio value can scale linearly with BTC price—i.e., you remove the IL gap (in theory), while earning roughly 2× the pool fees due to leverage. The catch is a re‑leverage loss from constant rebalancing, plus borrow cost.
Why continuously maintain a loan value at 50% of collateral?
A static leverage (one-time 2×, 3×, etc.) just rescales your exposure.
It doesn’t change the shape of the payoff curve.
You still end up with the same sublinear LP curve that underperforms simply HODLing in trending markets.
YB is different because the loan value is continuously maintained at ~50% of collateral.
That continuous rebalancing alters the composition rule of the position as price moves.
Instead of a one-off leverage scaling factor, you get a process that linearizes the payoff curve, effectively neutralizing impermanent loss while still harvesting fees.
Hence the design goal: earn enough flow to more than offset both.
YB’s mechanism embeds “one AMM sitting in another AMM”: BTC LP deposits; the protocol borrows crvUSD to create a 2× leveraged LP against BTC‑stable, then routes 50% of pool fees and the borrow stream into a dedicated rebalancing budget.
The stated APR identity: APR = 2 × pool yield − (borrow rate* + re‑leverage loss).
*The borrow rate is fully repurposed and reinvested to offset rebalancing costs
Parameter choice (concentration, max size, rebalance policy) governs that loss. Three main levers govern both yield potential and risk:
Liquidity concentration – Tighter ranges capture higher fees but require more frequent rebalancing (higher re-leverage loss).
Maximum pool size – Larger positions earn more fees and are more gas efficient to have higher TVL as you'd have more capital earning yield as the gas costs don't fluctuate depending on position size
Rebalance policy – How aggressively and frequently liquidity is repositioned. More frequent moves = better price tracking but higher budget burn.
In other words:
Aggressive parameters → higher fee potential in active markets but greater draw on the rebalance budget (risk of budget depletion).
Conservative parameters → lower volatility in net returns but more time spent away from the optimal price band, reducing gross fee capture .
The simulations run on historical CEX↔DEX arbitrage data (Binance vs. Curve AMM) show three important effects:
Base case (Curve Crypto AMM today): ~5.5% APR average with normal IL still present.
With 5% borrow stream into rebalance budget: APR improves to ~13% — meaning the extra budget allows the LP to stay in dense liquidity zones longer, more than offsetting the extra “cost” from redirecting borrow interest.
Full compounding-leverage + budget approach (2019–2024):
~20% average APR over 6 years.
A peak year (2021) with ~60% APR due to extreme volatility and large arb flows.
Net BTC growth example: 1 BTC in 2019 → ~3 BTC by end-2024 in the backtest scenario .
Token design: paying for emissions with real BTC opportunity cost
YB’s token model tries to align incentives by making every token “cost” real BTC yield.
LPs face a mutually exclusive choice: either take their pro‑rata pool fees in BTC now, or stake the LP token to earn YB emissions, foregoing fees. That forgone BTC is routed back into the distribution loop and therefore goes partially to veYB stakers and partially to ybBTC holders. The split is determined by the overall stake rate. In other words, YB issuance isn’t “free” liquidity mining; it is purchased with the LP’s opportunity cost in BTC. Governance follows a Curve‑like vote‑escrow model; veYB holders direct emissions and accrue BTC‑denominated protocol fees.
If it works, this creates a flywheel: attractive veYB yield → more LPs opt into YB emissions (sacrificing fees) → larger BTC fee stream to veYB → stronger governance pull to deepen BTC pools → more CEX↔DEX flow → larger fee base.

What’s genuinely novel—and what we’d still need to see
Novel:
IL mitigation via compounding leverage + budgeted rebalancing. It’s a clever fusion of market microstructure (arbitrage capture) and AMM control theory (budgeted repositioning), rather than just “more emissions.”
Emissions priced by foregone base‑asset yield. This “value‑protected” issuance curbs reflexive, costless inflation and pays veYB in BTC terms, not just YB, tightening the loop to real activity.
Composability with LSTs and Pendle. YB aims to be a source of BTC yield that other wrappers can tokenize and lever.
YB is designed to serve as a base layer of BTC yield that other protocols can tokenize and leverage. Much like Ethena’s sUSDe—where yield comes from volatility via funding rates (more volatility → more leverage → higher funding).
YB’s yield is driven by trading activity (more volatility → more order flow → more fees). This makes YB a natural fit for Pendle, enabling the creation of high-yield BTC fixed-rate products while giving traders a way to speculate directly on volatility.
To underwrite before we call it “infrastructure”:
Stress behavior. The critique up front is right: branding this “IL‑free” is marketing shorthand. A BTC crash can force unwinds; a crvUSD depeg would hit both legs at once. Circuit breakers slow loss, they don’t erase it.
YB response:
A 50% move in a single block would be devastating for YB and DeFi at large. That’s why YB chose BTC as the most mature and liquid crypto asset. As long as volatility remains within reasonable bounds, YB can reliably rebalance to keep LTV anchored at 50%.
If crvUSD were to depeg downward, LTV would actually improve. However, a prolonged deviation would erode effective leverage and reduce long-term yield.”
Rebalance budget sufficiency. In persistent trend moves or gappy markets, is the borrow‑funded budget enough to keep liquidity near the peak without bleeding? We’d want telemetry on realized re‑leverage loss vs. earned fees across regimes.
YB response:
Volatility ↑ → Volume ↑ → Fees ↑ → Rebalancing ↑
In other words, fees and number rebalancing are naturally correlated
Wrapper fragmentation risk. WBTC, cbBTC, tBTC each carry different custody/bridge risks. Slippage and oracle choices across wrappers matter to systemic health.
YB response:
Slippage isn’t an issue when unwinding an LP position. You simply repay the loan with the stablecoin from within the LP and receive tokenized BTC back, along with accrued trading fees. No swapping occurs on withdrawal, so no slippage is incurred.
A key requirement, however, is that the pools are backed by existing Curve pools with sufficient liquidity, since YB relies on Curve’s EMA mechanism.
Market structure tailwinds
Three forces make this timing interesting:
BTC volatility + ETF‑led liquidity. Vol brings fee flow; depth brings arbs. YB’s own modeling ties APR to vol spikes (e.g., 2021).
CeFi–DeFi convergence. Coinbase’s BTC‑backed loans powered by Morpho are a visible example of “regulated front‑ends, DeFi back‑ends.” If YB becomes the deepest BTC pool, CeFi desks could treat it like an on‑chain venue for working capital.
Yield‑native composability. Pendle and LSTs need real sources of base‑asset yield. If YB can supply a BTC‑denominated stream, tokenized fixed/float markets get much more durable.
If YB executes, we’d expect to see within 6–12 months:
Depth leadership in BTC‑stable pairs on major chains; time‑at‑top‑of‑book and realized spreads competitive with CeFi for retail size;
Repeatable BTC‑denominated yield through full cycles—e.g., single‑digit APR in quiet periods
veYB flywheel evidenced by rising share of LPs opting into YB emissions (i.e., paying in BTC yield), which in turn increases BTC streamed to veYB;
Pendle/LST integrations treating YB as a base yield source, not just another point farm.
Final take
YB’s core idea—use compounding leverage and a funded rebalance budget to neutralize IL and monetize BTC volatility—deserves serious attention. It is not magically risk‑free: sharp BTC drawdowns, stablecoin peg events, or liquidity gaps can still force losses and unwind positions. But compared with emissions‑driven “yield,” this is at least attacking the right problem: converting real order flow into base‑asset returns with explicit budgets, parameters, and governance.
If the live data matches the backtests and the protocol secures durable flow from quants, routers, and CeFi desks, YB could become the canonical on‑chain venue for BTC yield—and a building block for the institutional “on‑chain savings account” many of us have been waiting for.
