Balancer's veBAL model has the same problem as Curve's: boosted rewards require a multi-year lock that most liquidity providers will not accept. Aura solved it the same way Convex did, and became the default routing layer for Balancer liquidity as a result.
Mechanics
Deposit Balancer LP tokens through Aura, receive boosted BAL and AURA rewards, with the protocol pooling locked veBAL to provide the boost. auraBAL represents a liquid claim on locked BAL. Fee is around 19–25% of rewards, at the high end of the category.
The inherited risk
Aura's contracts have held without incident. Balancer's have not — the 2023 boosted-pool vulnerability forced emergency withdrawals and a 2025 exploit affected specific pool types again. A depositor in Aura is exposed to Balancer's pool contracts by construction, so the relevant security question is not only Aura's record but the specific Balancer pool underneath.
Governance dynamics
Aura controls a large share of veBAL, which gives it substantial influence over Balancer's emissions and creates a bribe market similar to Convex's. Value flows to AURA lockers from that influence.
Who should use it
Balancer liquidity providers who will not lock BAL, having checked which pool type they are entering and its incident history. The convenience is real; the underlying protocol risk is the thing to evaluate.
