Snapshot 6: Mesh Bridging of Treehouse Assets

Summary

This proposal seeks community approval to implement mesh bridging for all Treehouse assets, including tETH, tAVAX, and TREE, across the following networks:

• Ethereum
• Arbitrum
• Base
• Avalanche
• BNB

Mesh bridging enables direct asset transfers between any supported chain pair, removing the need to route through Ethereum. If approved, Treehouse will deploy this infrastructure using Chainlink CCIP to ensure secure, consistent, and transparent cross-chain transfers.

Motivation

Treehouse’s fixed income ecosystem is expanding across multiple networks, with tETH, tAVAX, and TREE now deployed across Ethereum, Arbitrum, Avalanche, Base, and BNB.

Currently, bridging paths are limited, with Ethereum acting as the primary routing layer. For example, users can bridge tETH from Ethereum to Arbitrum or Base, but cannot bridge directly between Arbitrum and Base.

By adopting a mesh bridging architecture, Treehouse can:

• Enable direct bridging routes between any supported chain pairs, minimizing fees and improving routing efficiency
• Allow liquidity to flow more freely across networks, supporting tAsset integrations and TREE market depth
• Improve the user experience for multi-chain yield strategies and governance participation

This proposal supports Treehouse’s goal of building fixed income infrastructure that scales efficiently across ecosystems.

Specification

If approved, this proposal will:

• Implement mesh bridging for the following Treehouse ecosystem assets:

  • tETH
  • tAVAX
  • TREE
  • Future Treehouse ecosystem assets

• Enable bridging between all supported networks:

  • Ethereum
  • Arbitrum
  • Base
  • Avalanche
  • BNB

• Leverage Chainlink CCIP as the interoperability layer for secure cross-chain transfers

• Maintain consistent total token supply across all networks using lock-and-burn mechanisms

Security and Infrastructure

To preserve the integrity of Treehouse assets:

• All bridge-related smart contracts will undergo security audits prior to deployment
• Cross-chain communication and token transfers will rely on Chainlink CCIP’s decentralized, production-grade infrastructure
• The Treehouse engineering team will monitor asset flows and balances across networks at the smart contract level

Implementation Plan

• Design & Integration: Finalize technical architecture and integration routes with Chainlink CCIP
• Audit: Submit bridging contracts for independent security review
• Deployment: Deploy bridge endpoints and enable full mesh bridging across supported networks
• Monitoring & Maintenance: Ongoing monitoring, with changes or improvements governed by the DAO

Voting Options

• For – Approve the implementation of mesh bridging for Treehouse assets using Chainlink CCIP
• Against – Reject the proposal
• Abstain – Record sentiment without voting for or against

Vote Outcomes

If FOR passes: Treehouse will proceed with development and deployment of mesh bridging infrastructure, enabling cross-chain bridging for tETH, tAVAX, TREE, and future assets.

If AGAINST passes: No changes will be made to the existing bridging architecture.

If ABSTAIN: No direct effect; recorded for sentiment but not counted toward quorum.
