2026-09-03

Breaking changes

  • Update RENEGADE signature: replace target and baseForQuote with recipient, buyToken, maxSellAmount, refundNativeEth, and maxRefundAmount
  • SolidlyV3 UniV3 fork removed from Sonic
  • All proportional-amount action arguments are now denominated in parts-per-million (ppm; denominator 1_000_000) instead of basis points (bps; denominator 10_000)
    • Affects the bps (now ppm) argument of UNISWAPV3, UNISWAPV2, BASIC, VELODROME, MAKERPSM, DODOV1, DODOV2, MAVERICKV2, EULERSWAP, HANJI, UNISWAPV4, BALANCERV3, PANCAKE_INFINITY, EKUBO, and EKUBOV3 actions.
    • Affects the maxBps (now maxPpm) argument of POSITIVE_SLIPPAGE
    • Action selectors are unchanged (the arguments are uint256 at the ABI level); only the interpretation of the value changes
    • In the packed fills encoding of UNISWAPV4, BALANCERV3, PANCAKE_INFINITY, EKUBO, and EKUBOV3, the leading proportion field of each fill (and the corresponding field of the non-VIP header) widens from 2 bytes to 3 bytes
    • BALANCERV3 wrap/unwrap flags move from bits 15/14 to bits 23/22 of the fill's proportion field
    • The Ekubo forwarding-extension flag moves from bit 15 to bit 23
    • The Permit2 balance-proportional sell amount sentinel widens: permit.permitted.amount > type(uint256).max - 1_000_000 now encodes a proportion in ppm as type(uint256).max - (1_000_000 - ppm)
    • Note that the UNISWAPV2 action STILL contains a basis-point-denominated packed field (the swap fee) in the upper 16 bits of swapInfo. This behavior remains unchanged.
  • For the actions UNISWAPV3_VIP and METATXN_UNISWAPV3_VIP, remove the first token (the sell token) from path, shortening the encoded length by 20 bytes. This token is now read from permit. Intermediate hop tokens and the final buy token are unchanged. The non-VIP UNISWAPV3 action is unchanged. Immunefi bug report 88903

      2. Encoding of:
        1. owner, amount, deadline, v, r, s in case of regular ERC2612 permit
