FIP-92: Vote-escrow the DAO’s BAL to veBAL

Summary

Vote-lock the protocol’s BAL inside the new veBAL system. This vote is used to determined the amount of BAL locked.

Context / Motivation

Balancer is releasing their new tokenomics, similar to Curve, where the new token that hold governance power is veBAL (vote-escrowed LP token of the 80 BAL / 20 WETH pool).

The protocol currently holds the equivalent of ~271k BAL:

• 261,146 1 inside the BAL/WETH pool (20% of the LP position is actually WETH)
• 8,525 1 on the BAL/WETH PCVDeposit
• 2,000 on the FEI/WETH PCVDeposit

Notable difference with Curve: the locking period for “veBAL” is maximum 1 year, and “veBAL” is actually a LP token, not a simple wrapper around BAL.

Specification

Re-use the contract used to manage veANGLE, in order to manage veBAL.

Initial veBAL delegate for Snapshot voting will be eswak.eth (can be changed anytime by OA Timelock).

Voting

This is an approval vote, the option with the most approval gets proposed onchain, unless "More discussions needed" wins.
