[BIP-434] Enable wstETH/4Pool Gauge [Arbitrum]

PR with Payload


This is a proposal to enable the gauge on Arbitrum for the wstETH / 4 weighted pool. As Balancer doubles down on the Arbitrum ecosystem with the updated airdrop incentives program, it makes sense for Balancer to have a liquidity route between stable coins and wstETH. This will facilitate a path for trades to be routed through and as the pool TVL grows, more swaps will be sent to Balancer through aggregators.

Protocol Description:

wstETH, is Lido’s wrapped staked Ethereum. USDC is the dollar backed stablecoin issued by Circle (USDC.e being the bridged version and USDC native version on optimism). DAI is the decentralized overcollateralized stablecoin by MakerDAO. USDT is the dollar backed stablecoin issued by Tether.


This proposal aims to add an uncapped veBAL gauge for the wstETH/4Pool (USDC-USDT-DAI-USDC.e) on Arbitrum, and request “core” pool status.


  1. Governance: Not applicable.
  2. Oracles: No.
  3. Audits: Not applicable.
  4. Centralization vectors: There are centralization risks with USDC, DAI, and USDT, though the market has clearly accepted those as minor for now.
  5. Market History: Bespoke stable tokens have well-known market history.
  6. Value: We will earn the protocol fee on trading. BIP-19 will incentivize TVL to continue to grow.
