[BIP-381] Enable Aave Boosted USDC/USDC.e Gauge [Arbitrum]

PR with Payload


This pool uses the composable stable pool factory v5 and contains two separate linear pool tokens; bb-a-USDC and bb-a-USDC. These are Balancer’s AAVE boosted Arbitrum native USDC, and bridged USDC. As Circle migrates from bridged to native USDC there are several dexes offering the ability to swap between both assets, which do bring in considerable volume. Balancer protocol will be earning yield on both boosted portions of this pool, making the token pairing more efficient for LPs. This gauge would enter as a “core pool” under BIP-19, meaning protocol fees earned by this pool would be used to bribe for votes on it. The gauge can be uncapped.

Protocol Description:

bb-a-USDC is a Balancer’s USDC boosted token implementation of USDC, leveraging AAVE’s boosted strategy. USDCe is bridged USDC from mainnet to Arbitrum.


This provides a trading route between the two USDC assets on Arbitrum. With the boosted aspect, an A of 5000, and swap fee of 0.005%, this swap route highly competitive, and more sustainable for liquidity providers to place their funds. The risk of a high A factor exposing the pool to being off balance is mute due the assets being virtually interchangeable. Competitors use higher swap fees and see utilization upwards of 100%.


  1. Governance: USDC is centralized and does not have a governance forum.
  2. Oracles: This pool only relies on the rate providers of the linear pools to inform when yield is earned.
  3. Audits: N/A
  4. Centralization vectors: USDC is inherently centralized.
  5. Market History: See here .
  6. Value: Balancer will earn the protocol fee on underlying bb-a-USDC and bb-a-USDCe yield. BIP-19 will incentivize TVL to continue to grow here with trading volume and this implementation will continue to draw in new volume, as well as showcase the power of these pool types.
