Overview
This proposal seeks community approval to implement mesh bridging for all Treehouse assets, including tETH, tAVAX, and TREE, across the Ethereum, Arbitrum, Base, Avalanche, and BNB networks.
The mesh bridging architecture will allow Treehouse assets to move seamlessly in all directions between supported chains, rather than limited transfer routes. This system enhances accessibility and supports more multi-chain yield strategies for Treehouse’s ecosystem.
If approved, the Treehouse protocol will integrate and deploy bridging infrastructure through our trusted interoperability provider, Chainlink CCIP, to ensure security, consistency, and on-chain transparency.
Motivation
Treehouse’s fixed income ecosystem is expanding across multiple chains, with tETH, tAVAX, and TREE now deployed across Ethereum, Arbitrum, Avalanche, Base, TAC, and BNB networks.
However, current bridging paths are limited, with Ethereum being the main liquidity hub that facilitates all bridging transactions. For instance, users can currently bridge tETH from Ethereum to Arbitrum or Base, but not directly between Arbitrum and Base.
By adopting a mesh bridging design:
- Users gain direct bridging routes between any supported chain pairs, minimizing fees and increasing routing efficiency.
- Liquidity can flow more efficiently across networks, supporting tAsset integrations and TREE market depth.
Specification
- Implement mesh bridging for the following Treehouse ecosystem assets:
- tETH
- tAVAX
- TREE
- Other future ecosystem assets
- Enable bridging between all supported networks**.**
- Leverage Chainlink CCIP for secure and decentralized cross-chain bridging.
- Ensure parity in token supply across networks, maintaining consistent total circulation through lock and burn methods.
Security and Infrastructure
To preserve the integrity of Treehouse assets:
- All bridge contracts will undergo rigorous security audits prior to deployment.
- Cross-chain communication security is handled natively by Chainlink CCIP’s battle-tested decentralized bridging infrastructure.
- The Treehouse engineering team will maintain visibility on Treehouse assets, tracking flows and balances across networks on the smart contract level.
Implementation Plan
- Design & Integration: Finalize technical specifications and integration routes with Chainlink CCIP.
- Audit: Submit bridging smart contracts for security audits.
- Deployment: Deploy bridge endpoints and enable full mesh bridging on all supported networks.
- Monitoring & Maintenance: Ongoing monitoring, with any necessary updates or improvements subject to DAO approval.
Next Steps
- Gather community feedback on this proposal.
- Submit proposal for formal DAO vote.
- Upon approval, begin development and deployment of mesh bridging infrastructure.
