The bridge between Bitcoin and Rootstock just got significantly smarter.
Flyover v2.3 brings a new level of automation, flexibility, and increased developer friendliness to the Bitcoin bridging experience. Whether you’re a liquidity provider, a dApp developer, or a Bitcoiner exploring Rootstock, this release strengthens the foundation of Bitcoin-native DeFi.
What’s New in Flyover v2.3?
