With the release of Bitlayer V2's whitepaper in 2025, developers now have access to an upgraded suite of SDKs that integrate seamlessly with the dual PoS and rollup architecture, enabling rapid prototyping of Bitcoin-native applications.
The JavaScript SDK has been enhanced to support BitVM-based fraud proofs, allowing devs to simulate state transitions locally before deployment.
For APIs, the JSON-RPC endpoints now include extensions for querying Bitcoin-anchored states, with methods like getStateRoot that return verified data in under 100 milliseconds.
Tooling updates include a Remix IDE plugin tailored for Bitlayer, featuring auto-completion for YBTC token interactions and built-in gas estimators.
Sample integrations showcase a yield farming dApp using YBTC as collateral: import the SDK, connect to testnet RPC, deploy a Solidity contract that mints YBTC via the BitVM Bridge, and handle events for real-time yields.
Another example involves integrating with Chainlink oracles for price feeds in a lending protocol, where devs use the Go SDK to batch transactions for efficiency.
The Quick Start Guide in docs provides step-by-step for setting up a local node with pruned state, syncing in minutes.
Hackathons hosted by @BitlayerLabs offer $BTR bounties for innovative builds, like cross-chain DEXs.
This ecosystem lowers barriers, with EVM compatibility ensuring Ethereum tools work out-of-the-box.
$BTR utility shines in dev grants, where proposals funded by $BTR treasuries accelerate projects.
#Bitlayer V3 preview promises parallel execution tools, boosting dev productivity further.
