BTC.b, a prominent Bitcoin asset on the Avalanche network, is transitioning to Lombard’s architecture and product suite. This move aims to facilitate multi-chain expansion and deeper integration with decentralized finance (DeFi) platforms. The transition, announced here, ensures that holders’ tokens, balances, and integrations remain unchanged, requiring no action from them. Protocols, however, have optional actions to consider.

Since its inception in 2022, BTC.b has been integral to Avalanche’s DeFi ecosystem, with approximately $550 million in circulation. It boasts deep integrations with platforms such as Aave, GMX, BENQI, and LFJ. Lombard has acquired the infrastructure and related assets of BTC.b, and its protocol will now oversee BTC.b’s bridge operations and security architecture. This transition promises full continuity for existing users and integrations.

Enhanced Security and Multi-Chain Expansion

The transition to Lombard’s architecture introduces a multi-layered security model. This model includes decentralized validation by a consortium of leading institutions, enhancing BTC.b’s security. The new architecture will initially deploy BTC.b on Ethereum, Katana, MegaETH, and Solana, expanding its reach beyond Avalanche.

BTC.b will operate on Lombard’s transparent, verifiable protocol architecture, offering a next-generation Bitcoin asset designed for the decentralized economy. It will be permissionless, non-custodial, and secure, bringing institutional-grade security to on-chain Bitcoin without traditional gatekeepers.

Implications for Users and Protocols

For users, BTC.b remains the same token, with unchanged contract addresses, symbols, and names. It continues to be backed 1:1 by native Bitcoin reserves, with no rehypothecation or staking. All holdings, addresses, and wallet integrations remain unaffected, and existing integrations with DeFi protocols like Aave and GMX will continue to operate normally.

Protocols will notice changes in the BTC redemption process. The previous ‘unwrap’ function is deprecated, and a new Lombard contract must be used for redemptions. Standard price feeds will continue to function, but proof of reserve feeds will need updating to Lombard-based feeds when available from Chainlink.

The transition is expected to complete in Q4 2024, with minimal user-facing downtime. During the cutover, minting and redeeming BTC.b may be unavailable for up to two hours. However, any transactions sent during this period will experience only slight delays, with no risk of fund loss.

Why This Matters: Impact, Industry Trends & Expert Insights

The transition of BTC.b to Lombard’s architecture represents a strategic move to enhance security and facilitate multi-chain expansion, crucial for its integration into decentralized finance (DeFi) platforms.

According to Lombard Finance, their architecture has significantly impacted DeFi platforms by enhancing Bitcoin’s utility within the ecosystem. This aligns with BTC.b’s transition, which aims to expand its reach and enhance security using Lombard’s architecture.

As per insights from experts, the transition to Lombard’s architecture is seen as pivotal for Bitcoin’s multi-chain expansion and deeper integration into DeFi. This supports BTC.b’s goal to leverage Lombard’s robust ecosystem for enhanced on-chain utility and security.
