Traditional AMM liquidity provision comes with a familiar set of trade-offs: deposit two assets in a specific ratio, earn fees from trades, and hope that impermanent loss doesn't erode your gains. For Bitcoin holders, this model has always been uncomfortable. Why pair BTC with a stablecoin just to earn yield, only to end up with less BTC than you started?
Chainflip's Boost pools work differently. You deposit a single asset, earn a flat fee every time your liquidity is used, and withdraw exactly what you deposited. No rebalancing, no impermanent loss, no need to hold a second token.
Two Models, Two Sets of Economics
To understand why Boost pays LPs differently, you need to understand what you're actually providing in each model.
How AMM LPs Earn
In a traditional AMM like Uniswap or Curve, liquidity providers deposit two assets into a pool. The AMM uses a bonding curve to price trades between those assets. When traders swap, they pay a percentage fee that gets distributed to LPs proportionally.
The catch is that your position constantly rebalances. If BTC rises against USDC, the AMM sells your BTC for USDC to maintain the curve. You end up with more USDC and less BTC than if you'd simply held.
This rebalancing is impermanent loss. It becomes permanent when you withdraw at different price ratios than when you deposited.
How Boost LPs Earn
Boost pools don't use a bonding curve. Instead, they provide single-sided liquidity that accelerates deposit confirmations for swaps. When someone swaps into BTC, Boost LPs can front the Bitcoin immediately rather than waiting for full block confirmations.
In exchange, the swapper pays a flat fee. That fee goes directly to the LP whose liquidity was used. There's no curve, no rebalancing, and no exposure to price movements between asset pairs.
When you deposit 1 BTC into a Boost pool, you withdraw 1 BTC plus whatever fees you've accumulated. Your BTC exposure never changes.
A Concrete Example: BTC LP Returns
Let's compare how a Bitcoin LP might fare in each model over a period where BTC price increases significantly.
Scenario: AMM LP (BTC/USDC Pool)
Assume you deposit $50,000 worth of BTC and $50,000 USDC into a traditional AMM pool. Your total position is $100,000. Over the period, BTC doubles in price.
Without any trading activity, your position would now be worth roughly $141,000 due to impermanent loss. You'd have more USDC and less BTC than if you'd simply held both assets separately.
The fees you earned might offset some of this loss, but you're fighting against the rebalancing mechanic. In a strong BTC bull run, holding BTC outperforms LPing in a BTC pair.
Scenario: Boost LP (BTC Only)
Now assume you deposit the same amount of BTC into a Boost pool. Over the same period, your BTC doubles in value just like everyone else's. You've also earned fees denominated in BTC from deposits that used your liquidity.
When you withdraw, you have your original BTC plus fee earnings. There's no IL calculation because you were never on a curve. Your returns track BTC plus yield, not BTC minus rebalancing losses plus yield.
Fee Structure Differences
The fee mechanics are fundamentally different between the two models.
AMM Fees: Percentage of Trade Volume
AMM LPs earn a percentage of every trade that touches their liquidity range. Higher volume means higher fees, but you're competing with all other LPs in the pool. Your share depends on how much of the pool you represent.
Fee APRs fluctuate wildly based on volume, pool size, and fee tier. A 0.3% fee pool needs substantial volume to generate meaningful returns.
Boost Fees: Flat Rate Per Deposit
Boost LPs set a fee tier when they deposit. Swappers see Boost pools ranked by fee, and deposits get filled starting with the lowest fee tier that has available liquidity. When your liquidity is used, you earn that flat fee on the deposit amount.
This creates predictable economics. You know exactly what you'll earn per unit of liquidity deployed. The variable is utilization: how often your liquidity gets used.
Higher fee tiers earn more per use but get filled less frequently. Lower fee tiers get filled more often but earn less per transaction. LPs can choose their position on this spectrum. For more on getting started, see the 5-minute Boost liquidity tutorial.
Risk Profile Comparison
Beyond the fee mechanics, the risk profiles differ substantially.
AMM Risks
Impermanent loss from price divergence
Requiring exposure to a second asset you may not want to hold
Smart contract risk on whichever chain hosts the AMM
Concentrated liquidity positions can go out of range, earning nothing
Boost Risks
Liquidity is locked during active deposits until the swap settles
Utilization varies based on swap demand and your fee tier

Neither model is risk-free. But for Bitcoin holders who want to earn yield without taking on stablecoin exposure or betting against BTC appreciation, Boost's single-sided model removes the biggest pain point of traditional AMM LPing.
When Each Model Makes Sense
AMM LPing still has valid use cases. If you're bullish on both assets in a pair and expect range-bound trading, fee accumulation can beat holding. Stablecoin pairs with minimal price divergence minimize IL by design.
Boost makes sense when you want to earn yield on an asset you plan to hold anyway, without converting it into a position that bets against your original thesis. For BTC maxis who believe in long-term appreciation, earning fees while staying 100% in BTC aligns incentives differently than AMM LPing ever could.
Conclusion
The economics of Boost versus traditional AMM LPing come down to what you're optimizing for. AMMs offer exposure to trading volume across a price curve, with the trade-off of impermanent loss and two-sided deposits. Boost offers single-sided deposits with flat fee earnings and no rebalancing risk.
For Bitcoin LPs, this distinction matters. You can deposit BTC, earn fees in BTC, and withdraw BTC without ever worrying about how much your position rebalanced into something else. That's a fundamentally different value proposition than any AMM can offer.

What is impermanent loss and why doesn't Boost have it?
Impermanent loss occurs when AMM pools rebalance your position as prices change, leaving you with a different asset ratio than you deposited. Boost pools don't use a bonding curve or rebalancing mechanism. You deposit one asset and withdraw that same asset plus fees, so there's no IL exposure.
Can I deposit just Bitcoin into Boost without needing a second token?
Yes. Boost pools are single-sided. You deposit BTC and only BTC. There's no requirement to pair it with a stablecoin or any other asset.
How do Boost fees compare to AMM fees?
AMM LPs earn a percentage of trade volume distributed across all LPs. Boost LPs earn a flat fee per deposit when their liquidity is used. Boost fees are predictable per transaction, while AMM fees depend on volume and your share of the pool.
What determines how often my Boost liquidity gets used?
Swap demand and your fee tier. Lower fee tiers get filled first, so they see higher utilization. Higher fee tiers earn more per use but get selected less frequently.
Is Boost better than AMM LPing for Bitcoin holders?
For holders who want to stay fully exposed to BTC and avoid rebalancing into stablecoins, Boost aligns better with that goal. AMM LPing can still make sense for range-bound pairs or when you want exposure to both assets.
