[BIP-809] Enable YieldFi yUSD/USDC gauges on Balancer v3 Base deployment

PR with Payload

https://github.com/BalancerMaxis/multisig-ops/pull/1901

Summary:

This is a proposal to enable the root gauge https://etherscan.io/address/0x0D3F5D4022279c536a53aaa6bb8c225A0226d168 on Ethereum, [which redirects rewards to the child gauge https://basescan.org/address/0x7Ac2f85069470959f5960B6054479aD46dB4d818 on Base,] for the pool https://basescan.org/address/0x424d19d482a891b2c5cb881d651fbc32b349cb3c (surge yUSD/ waBasUSDC).

Motivation:

We have run incentives on our deployment of same pair on Arbitrum and saw the TVL grew to $700k+ in less than 2 months demonstrating demand for this liquidity pairing. As we have historically seen high demand on Base, compared to Arbitrum we are expanding this pair to base and by enabling gauge rewards, this pool will attract additional TVL, benefiting both protocols while creating one of the highest-yielding stable opportunities on Base.

This integration creates synergies between YieldFi, Balancer, and Aave, boosting activity across all three ecosystems.

Protocol Description:

yUSD is the yield bearing token by YieldFi deployed on Base and is backed by stablecoins like USDC/USDT/USR/wstUSR that strategically allocates assets across blue-chip DeFi protocols to generate 10-20% yields (currently 10.23% APY). The product features daily yield distribution, institutional-grade security, and full on-chain transparency.

waBasUSDC is the wrapped version of Aave's interest-bearing aBasUSDC on Base, which allows users to earn yield from USDC deposits in Aave.

Specifications:

Governance: YieldFi operates with a multi-sig wallet requiring 3/5 signatures from core team members

Oracles: https://docs.yield.fi/resources/oracles

Audits: https://docs.yield.fi/resources/audits

Centralization vectors: The primary centralization vectors include the multi-sig custody and professional team management of yield strategies (necessary for optimal returns)

Market History: yUSD has maintained perfect positive yieldcurve with no drawdown since launch with zero instances of depegging.
