GmxCallbackLib

GmxCallbackLib

Storage layout and helpers for the GMX v2 order callback extension. The data is stored in the pool proxy and updated by EGmxCallback when GMX keepers execute, cancel, or freeze orders.

All state is ERC-7201 namespaced; MixinStorage asserts the slot.

GMX_CALLBACK_DATA_SLOT

bytes32 GMX_CALLBACK_DATA_SLOT

ERC-7201 slot for GMX callback data.

Must stay in sync with MixinStorage assertion.

CLAIMABLE_FUNDING_AMOUNT_KEY

bytes32 CLAIMABLE_FUNDING_AMOUNT_KEY

GMX v2 DataStore keys used by the callback extension and NAV accounting.

CLAIMABLE_COLLATERAL_AMOUNT_KEY

bytes32 CLAIMABLE_COLLATERAL_AMOUNT_KEY

CLAIMABLE_COLLATERAL_FACTOR_KEY

bytes32 CLAIMABLE_COLLATERAL_FACTOR_KEY

CLAIMABLE_COLLATERAL_REDUCTION_FACTOR_KEY

bytes32 CLAIMABLE_COLLATERAL_REDUCTION_FACTOR_KEY

CLAIMED_COLLATERAL_AMOUNT_KEY

bytes32 CLAIMED_COLLATERAL_AMOUNT_KEY

CLAIMABLE_COLLATERAL_TIME_DIVISOR_KEY

bytes32 CLAIMABLE_COLLATERAL_TIME_DIVISOR_KEY

CLAIMABLE_COLLATERAL_DELAY_KEY

bytes32 CLAIMABLE_COLLATERAL_DELAY_KEY

InvalidCallbackAccount

error InvalidCallbackAccount()

ClaimableCollateralInfo

Metadata for a recorded claimable-collateral DataStore key. The factor/reduction/claimed keys are recomputed at NAV time to minimize callback gas costs.

struct ClaimableCollateralInfo {
  address token;
  address market;
  uint256 timeKey;
}

GmxCallbackSlot

Storage layout for the GMX callback extension.

struct GmxCallbackSlot {
  struct Bytes32Set trackedMarkets;
  struct Bytes32Set claimableCollateralKeys;
  mapping(bytes32 => struct GmxCallbackLib.ClaimableCollateralInfo) claimableCollateralInfo;
}
