How Boosty Labs Enabled Native Bitcoin Liquidity: with Rootstock’s Flyover Protocol

Rootstock is an EVM-compatible blockchain secured by the Bitcoin network, designed to bring smart contract functionality to Bitcoin. To unlock real DeFi capabilities for BTC holders, Rootstock initiated the development of Flyover — a cross-chain liquidity provider platform enabling seamless BTC utilization across ecosystems.
Boosty Labs partnered with Rootstock to support the development of Flyover, helping bridge the gap between Bitcoin’s security and DeFi’s flexibility.

Here’s how we did it

The Challenge

Bitcoin, despite being the most secure and widely adopted blockchain, lacks native smart contract capabilities required for advanced DeFi use cases such as lending, borrowing, and liquidity provision.
This created several critical limitations:

Our Solution

Boosty Labs contributed to the development of Flyover, a cross-chain liquidity protocol built on Rootstock that connects Bitcoin and Rootstock ecosystems.

Cross-chain Liquidity Layer
☑️ Built a mechanism allowing users to move BTC between Bitcoin and Rootstock networks
☑️ Enabled bi-directional operations:
☑️ BTC → Rootstock (for DeFi usage)
☑️ Rootstock → BTC (for liquidity exit)
Instant Liquidity via LPs
☑️ Designed a system where Liquidity Providers front liquidity, eliminating long bridging times
☑️ Users can instantly lend or borrow BTC without waiting for on-chain confirmations
Smart Contract Enablement via Rootstock
☑️ Leveraged Rootstock’s EVM compatibility to run DeFi logic on BTC-backed assets
☑️ Enabled lending/borrowing flows using smart contracts while maintaining BTC backing
Seamless User Experience
☑️ Abstracted complex bridging logic into a single unified flow
☑️ Reduced friction for both LPs and end users

Impact and Results

With Flyover, Rootstock significantly expanded Bitcoin’s DeFi capabilities:

Enabled
near-instant BTC liquidity across chains
Bridged
Bitcoin into a smart contract-enabled environment
Opened
the door for native BTC lending and borrowing
Improved
UX compared to traditional bridges by removing delays
Created
infrastructure for future Bitcoin-native DeFi applications
