[BIP-884] Wire Up BAL Token on Plasma Chain

PR with Payload

https://github.com/BalancerMaxis/multisig-ops/pull/2504

Summary

This proposal establishes LayerZero cross-chain communication for the BAL token between Ethereum mainnet and Plasma chain, enabling veBAL system integration and BAL emissions on Plasma following the successful completion of Month 3 checkpoint criteria as per BIP-871.

Introduction

Plasma chain has successfully met the Month 3 checkpoint requirements for strategic deployment confirmation:

• Total Value Locked (TVL) exceeds $75M

• DAO revenue from fees surpasses $15k

• At least 5 pools with $10M or more in TVL

Having achieved these milestones, this proposal proceeds with the next phase: wiring up the BAL token to enable deeper tokenomics integration and unlock veBAL governance and BAL emissions on Plasma chain.

Motivation

The successful performance of Plasma chain demonstrates strong product-market fit and sustainable operations. Integrating the veBAL system and BAL emissions on Plasma will:

1. Unlock BAL Emissions: Activate gauge voting and BAL rewards for Plasma liquidity providers

2. Strengthen Ecosystem: Deepen the integration between Plasma and the broader Balancer ecosystem

3. Fulfill Strategic Roadmap: Complete the planned progression from checkpoint validation to full tokenomics integration

This wire-up is the technical prerequisite for enabling cross-chain BAL transfers and gauge functionality on Plasma, aligning with the strategic deployment framework established during the chain's launch.

Technical Specification

This proposal configures the LayerZero bridge for BAL token on Ethereum mainnet to communicate with Plasma chain (LayerZero chain ID: 383).

Contract Actions

Target Contract: 0xe15bcb9e0ea69e6ab9fa080c4c4a5632896298c3 (BAL LayerZero token bridge on Ethereum)

Transaction 1: Set Trusted Remote Address

Function: setTrustedRemoteAddress(uint16 _remoteChainId, bytes _remoteAddress)

Parameters:

• _remoteChainId: 383 (Plasma LayerZero chain ID)

• _remoteAddress: 0x22625eEDd92c81a219A83e1dc48f88d54786B017 (BAL token on Plasma)

This establishes a trusted connection between the BAL token contracts on Ethereum and Plasma, allowing secure cross-chain transfers via LayerZero.

Transaction 2: Set Minimum Destination Gas

Function: setMinDstGas(uint16 _dstChainId, uint16 _packetType, uint256 _minGas)

Parameters:

• _dstChainId: 383 (Plasma LayerZero chain ID)

• _packetType: 0 (standard transfer packet type)

• _minGas: 100000 (minimum gas units required on destination)

This sets the minimum gas requirement for LayerZero message execution on Plasma, ensuring reliable cross-chain message delivery.

Execution

The proposal will be executed via the DAO multisig (0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f) on Ethereum mainnet after a successful governance vote.
