[BIP-427] Enable USDC-USDT-DAI-USDC.e stable pool gauge [optimism]

PR with Payload


This is a proposal to enable gauge on optimism for the 4 stable pool, in view of the native USDC deployment on optimism. The pool contains bridged USDC, native USDC, together with two other stable coins, USDT and DAI. Its amplification is 1000 with trading fee set at 0.1% currently.

Protocol Description:

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 4stable pool (USDC-USDT-DAI-USDC.e) on Optimism, and request β€œcore” pool status.
We aim to build this pool to be the main stablecoin liquidity on Balancer / Beethoven X on optimism, and hope to bootstrap its liquidity using the gauge.


  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.
