## Introduction veBoost V2 was first introduced in this [forum post](https://forum.balancer.fi/t/bip-141-introduce-veboost-v2/4160) several years ago, and has been working since then. In a nutshell, it allows users to delegate (“transfer”) their veBAL balance to other accounts. ## Specification We have two veBAL lockers (delegators) that currently cannot delegate their veBAL balances, as the contracts are not prepared to do so: - tetuBAL mainnet locker: `0x9cC56Fa7734DA21aC88F6a816aF10C5b898596Ce` - sdBAL locker: `0xea79d1A83Da6DB43a85942767C389fE0ACf336A5` To allow the lockers to operate their veBAL balances, we’ll follow the same approach that has already been executed on past versions of the delegation contract as described in [this forum post](https://forum.balancer.fi/t/tribe-dao-boost-delegation/3218/4). In short, veBoost 2.1 shall add hardcoded infinite allowance for operators designated by each DAO to be able to manage the veBAL balance in the name of the lockers: - Operator tetu: `0xB9fA147b96BbC932e549f619A448275855b9A7D9` - Operator stakeDAO: `0xB0552b6860CE5C0202976Db056b5e3Cc4f9CC765` Other than that, the new implementation of the veBoost contract shall be equivalent to the active one in terms of functionality. The state of the current veBoost contract shall be ported over to the new one using a permissionless `migrate` function, which is the only significant modification over the code. This means that existing delegations as of Jun 23, 2025 won’t need to be recreated manually. The rest of the modifications to the code are just readability improvements without any other practical effect; complete changes can be seen [here](https://github.com/balancer/balancer-v2-monorepo/pull/2577). ## Technical Specification Call `setDelegation` on the VotingEscrowDelegationProxy ([0x6f5a2eE11E7a772AeB5114A20d0D7c0ff61EB8A0](https://github.com/balancer/balancer-deployments/blob/e8b80838f3d28ec24f80beac3040888eb09df8ee/addresses/mainnet.json#L290)) with the following arguments: - delegation: `0x2cf8e145Bdfe7c52b49AD9bB3c294a31B2736c59` Doing this requires the permission to call `setDelegation`, which is [0xac0fcdc4520d7bde1c58bbefd7c8dd39aaf382a20c27991134c14fe63d2c96f3](https://github.com/balancer/balancer-deployments/blob/e8b80838f3d28ec24f80beac3040888eb09df8ee/action-ids/mainnet/action-ids.json#L418). This permission is currently held by the Governance DAO Multisig (`0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f`), so it doesn’t need to be granted. ### Preseed The existing boosts have already been loaded into the new contract in [this tx](https://etherscan.io/tx/0x3958bb067d34a6dde60318e2f6ff3bcb4e97f48ab73bdc80c5f583b2838d006a). No further action is needed other than wiring up the contract to the rest of the system as described above. ### Risk The contract is fundamentally the same, the migration function can only be called once and the state that is ported over to the new contract is hardcoded. If there is a mistake (e.g. a missing delegation) it can be created again using the usual mechanisms. ---

Really appreciate this migration and very nice clean-up work! This will enable tetu to delegate their veBAL power to StakeDAO which they requested a while ago. ---

Thank you for your effort! It’s a really important feature 🫡 ---
