Chainflip has two products where a BTC holder can put their bitcoin to work: Boost and Lending 2.0. Both accept native BTC. Both are non-custodial. Both have been battle-tested. Boost has been running for over two years without a single BTC deposit lost to a reorg or any other issue.
The difference is what the deposit earns.
Boost pays you a fee for accelerating BTC swaps and deposits on Chainflip.
Lending 2.0, since its release in June 2026, merged the BTC lending pool with the Boost pool. Any BTC supplied to Lending 2.0 automatically earns the same Boost fees a Boost-only supplier would earn, plus a second yield stream on top: the lending supply rate, paid by anyone borrowing stablecoins against BTC collateral.
Same BTC. Same risk profile. Two yield streams instead of one.
If you are currently supplying to Boost, moving your BTC into Lending 2.0 is a strict upgrade. Same asset, same custody model, same withdrawal semantics, and additional revenue. This post walks through why, and answers the question most Boost suppliers ask before switching: what am I giving up?
What Boost Pays
Chainflip Boost is a single-sided BTC liquidity product. You supply native BTC and earn a fee every time Boost is used to accelerate a swap or deposit that draws from your pool. Since Boost is single-sided, there is no impermanent loss.
Boost has been running in production for over two years. No supplier has lost a deposit to a Bitcoin reorg or any other issue. The full technical details are in the Boost risks documentation.
The important point for this comparison: Boost pays Boost fees, and only Boost fees.
What Lending 2.0 Adds on Top
Lending 2.0 launched with a specific structural change. Chainflip merged Boost's BTC pool with the Lending BTC pool. From that point onward, any BTC supplied to Lending 2.0 automatically became part of Boost as well.
So supplying BTC to Lending 2.0 now earns two things:
Boost fees. Same rate as a Boost-only supplier would earn, drawn from the same underlying accelerated-swap activity.
Lending supply interest. Paid by anyone borrowing stablecoins (USDT, USDC) against BTC collateral in the Lending 2.0 pool. Utilization-based, so the rate moves up as borrow demand rises and down as it slackens. Same interest-rate model class as Aave or Compound, but the yield here stacks on top of Boost fees rather than being paid alone.
Neither of these requires an opt-in. Supply the asset via the Lending 2.0 interface and both streams accrue automatically.
What Doesn't Change When You Move
The main hesitation Boost suppliers have is: am I giving something up by switching?
Custody model. Both products are secured by Chainflip's validator network under the same decentralized custody model. No centralized custodian on either side.
Withdrawal. You can withdraw from either product at any time, up to the pool's available liquidity at that moment. In a utilization-based lending market like Lending 2.0, that phrase carries some weight and is worth unpacking.
At any point in time, part of the BTC pool is deployed. Some sits against active loans (borrowers holding USDT, USDC, or BTC positions), some acts as Boost capital for in-flight accelerated swaps, and the rest is liquid reserve. Withdrawal comes out of the reserve. If pool utilization is low, the reserve is deep and withdrawal is effectively instant. If utilization is high, the reserve is smaller and a large withdrawal may need to wait until borrowers repay, liquidations settle, or new suppliers arrive at the higher prevailing yield.
Chainflip enforces a utilization cap on the BTC pool. It cannot be lent out beyond that cap, however strong borrow demand gets. The cap guarantees there is always enough BTC on hand to liquidate every open loan simultaneously if the worst case ever arrives, and that same buffer provides floor liquidity for supplier withdrawals.
This constraint applies equally to Boost and Lending 2.0 because they share the pool. It is not new risk from switching. And the tradeoff is baked into the yield: the lending supply rate rises as utilization rises, so when withdrawal is temporarily constrained, the yield being earned is at its highest.
Reorg protection. Same underlying machinery. Boost's two-year clean track record on Bitcoin reorgs applies to Lending 2.0 too, because it is the same pool.
Single-sided. No impermanent loss on either product. You supply BTC, you get back BTC.
The delta between Boost-only and Lending 2.0 runs in one direction: Lending 2.0 pays more, for the same BTC, at the same risk.
Optional Upside: Borrow Against Your BTC
Beyond just supplying, Lending 2.0 also lets you borrow stablecoins against your BTC. This is not required. You can supply BTC to Lending 2.0 and never open a loan.
But if you have a reason to hold some USDT or USDC without selling your Bitcoin (rebalancing, expenses, taking a position elsewhere), Lending 2.0 lets you do that in the same interface, without moving your BTC anywhere. Your BTC continues to earn Boost fees plus supply interest while backing the loan.
Boost-only suppliers cannot do this. They have a supply position and that is it.
Chainflip Lending 2.0's borrow rules:
Native BTC is the only collateral accepted.
Maximum loan-to-value is 80%.
Borrow markets available: BTC (on Bitcoin), USDT (on Ethereum), USDC (on Ethereum).
Interest on the borrowed amount is utilization-based, same as supply.
How to Move Your BTC From Boost to Lending 2.0
The mechanic is straightforward: withdraw from the Boost interface, then redeposit through lp.chainflip.io/lending. Existing Boost deposits are not automatically re-tagged as Lending 2.0 positions, so the switch is a user action.
Once your BTC is deposited via Lending 2.0, both Boost fees and lending supply interest start accruing automatically. No further setup, no opt-in flags.
For live rates on the lending side, check the Lending 2.0 dashboard directly. Supply rates move with pool utilization and are not fixed.
Bottom Line
Same asset, same custody, same withdrawal semantics, same risk. More revenue.
For an existing Boost supplier, there is no scenario where staying in Boost-only pays more than moving to Lending 2.0. The Boost fee stream you were already earning continues to flow through in Lending 2.0, and you pick up a second yield stream on top from the lending side of the pool.
If you were on the fence, this is the case for moving.

Find us:
Do I earn the same Boost APY in Lending 2.0 as I do in Boost alone?
Yes. Since Lending 2.0 merged with the Boost pool, BTC supplied to Lending 2.0 automatically participates in Boost at the same fee rate as a Boost-only supplier.
What extra yield do I earn by moving to Lending 2.0?
The lending supply rate, paid by anyone borrowing stablecoins against BTC collateral. It is utilization-based, so the rate moves with borrow demand. See lp.chainflip.io/lending for live numbers.
Do I have to borrow anything to earn the lending yield?
No. Supplying BTC alone earns both Boost fees and the lending supply rate. Borrowing against your BTC is optional.
Am I taking on new risk by moving to Lending 2.0?
Not if you only supply. The custody model, withdrawal semantics, and reorg protection are identical to Boost. Additional risk only applies if you choose to open a loan against your BTC, in which case there is liquidation risk on that loan.
How do I move my BTC from Boost to Lending 2.0?
Withdraw from the Boost interface, then redeposit through lp.chainflip.io/lending. Your BTC will then earn both Boost fees and lending supply interest automatically.
