BladeSwap

BladeSwap is a veDEX on Blast that launched in March 2024, reworking the ve(3,3) model. Users lock BLADE into veBLADE and vote weekly on where emissions go, with voters claiming pool bribes in real time. All fees from V2 constant-product pools flow to the gauge, while V3 concentrated pools send forty percent to voters and sixty percent back to liquidity providers.

Unlike classic ve(3,3), it dropped rebase in favour of real-time voting and continuous optimisation, so emissions follow current yield rather than lock duration. Blast's native yield, including ETH staking interest, USDB Treasury returns and gas refunds, was folded into incentives and initially distributed through a daily free loot box for swap, LP and governance participants. Contracts support batch transactions that combine approval, swap and stake, and the router splits orders to limit price impact. Emissions settle weekly, and the votes a pool attracts set its share of BLADE in the next period.
