BitFi brings sophisticated delta-neutral yield strategies previously exclusive to institutional players directly to everyday Bitcoin holders on Core. This Bitcoin yield protocol democratizes institutional-grade financial strategies, offering accessible on-chain access to the same tactics once reserved for high-net-worth individuals and treasury companies.
What Is BitFi?
BitFi is a Bitcoin liquidity protocol that democratizes institutional-grade yield strategies for all Bitcoin holders. Users deposit BTC and receive bfBTC, a yield-bearing token backed 1:1 by real BTC held in custody.
There's no need to bridge, manage complex smart contracts, or run your own trading strategies. BitFi handles sophisticated delta-neutral strategies under the hood while your BTC remains in secure, segregated custody.
Building on Core's Bitcoin DeFi Foundation
BitFi operates within Core's expanding Bitcoin DeFi ecosystem, where protocols compete on yield generation, risk management, and user experience. The protocol leverages Core's unique position as the Bitcoin Everything Chain, where Bitcoin yield and DeFi composability coexist at institutional scale.
How Custody Works
All BTC deposits are held in cold storage by Ceffu, a regulated institutional custodian. BitFi uses MirrorX, an off-exchange settlement system, to execute trading strategies on Binance without moving the underlying BTC.
This setup gives users institutional-grade market exposure while preserving custody and minimizing counterparty risk.
Sophisticated Yield Strategies
BitFi's yield is generated through delta-neutral quantitative strategies previously exclusive to institutional players:
Funding Rate Arbitrage: Earn premiums by shorting perpetual futures against long spot BTC
Basis Trading: Capture spreads between spot and future prices
Optional Protocol Staking: In certain cases, additional staking rewards are layered on top
These strategies aim for steady, market-neutral returns, historically delivering over 4.5% APY while maintaining Bitcoin exposure.
How bfBTC Works
When you deposit BTC, you receive bfBTC, a yield-bearing token that tracks your BTC plus accrued yield.
No extra reward token required
No claiming process needed
Yield is reflected in the bfBTC : BTC exchange rate, updated daily
As institutional-grade yield accrues, the exchange rate increases. When you unstake, you receive more BTC than you deposited.
Core Ecosystem Integration
bfBTC is fully composable across Core's Bitcoin DeFi ecosystem, creating layered yield opportunities:
Use as collateral in lending protocols like Colend
Provide liquidity in DEX pools to earn additional trading fees
Participate in other DeFi protocols without giving up BTC exposure
Stack returns through composable strategies
This composability creates layered yield opportunities where bfBTC establishes enhanced baseline yield that can then be deployed into additional strategies throughout Core's Bitcoin DeFi ecosystem.
Impact on Core's Bitcoin DeFi Flywheel
BitFi contributes to Core's powerful Bitcoin DeFi flywheel in multiple ways:
Increased Bitcoin TVL: More Bitcoin gets locked into Core's ecosystem through BitFi's custody and yield strategies, growing the total value secured by Core.
Enhanced Liquidity: bfBTC drives liquidity into Core's broader DeFi ecosystem, enabling enhanced lending, borrowing, and trading activities.
Transaction Fee Generation: Increased DeFi activity generates more transaction fees, which flow back to consensus participants, further enhancing the attractiveness of Bitcoin timelock and dual participation strategies.
Retail Reinvigoration: BitFi offers accessible, differentiated yield products for yield-seeking retail holders, introducing a dynamic, participatory layer atop passive Bitcoin holding.
The Composable Future
BitFi demonstrates how Bitcoin yield protocols can create network effects where each new integration enhances the utility and liquidity of the entire Bitcoin DeFi stack on Core.
Getting Started
- Deposit BTC
From the Bitcoin network (native BTC)
Or from an EVM chain (e.g. BTCB, WBTC)
- Receive bfBTC
Minted 1:1 based on the current exchange rate
- Earn institutional-grade yield
Daily exchange rate updates reflect performance
- Unstake anytime
Redeem bfBTC for more BTC than you deposited
Risk Considerations
Funding spreads may turn negative, reducing returns
Exchange risk exists, even with off-exchange settlement
Smart contract risk applies on the EVM side
All contracts are audited, and custody is fully segregated, but users should assess risk as with any yield product.
Why It Matters for Core
BitFi unlocks institutional-grade Bitcoin yield strategies for everyday users while strengthening Core's position as the Bitcoin Everything Chain. It demonstrates how Bitcoin yield protocols can democratize sophisticated financial strategies, creating deeper Bitcoin liquidity, more collateral in the ecosystem, and stronger foundations for Bitcoin-native DeFi.
For Core, this means a more vibrant Bitcoin DeFi ecosystem where previously exclusive yield opportunities become accessible to all Bitcoin holders, driving adoption and strengthening the flywheel that makes Core the natural home for Bitcoin yield and DeFi activity.
