Bifrost Node v2.1.0

Release Date: September 11, 2025
Rust Compiler: rustc 1.89.0 (29483883e 2025-08-04) or later

Summary

Bifrost Node v2.1.0 introduces significant enhancements to both Ethereum and Bitcoin interoperability infrastructure. Major updates include Pectra Ethereum Hard Fork support with EIP-7702 account abstraction features, the addition of the BLAZE (BRP Layer for Autonomous Zero-trust Execution) pallet for advanced Bitcoin UTXO management, comprehensive upgrades to Substrate and Frontier dependencies, and substantial improvements to the BTC relay system. This release focuses on optimizing both Ethereum account abstraction capabilities and Bitcoin UTXO management while strengthening the cross-chain infrastructure.

⚠️ Important

Due to updates that occurred on the client-side when upgrading to bifrost-polkadot-stable2506, client upgrades are mandatory for both testnet and mainnet node operators. All node clients running previous versions must upgrade to v2.1.0 for continued compatibility, enhanced Ethereum account abstraction support, Bitcoin relay functionality, and improved stability.
