API Reference¶

almanak.connectors.gmx_v2 ¶

GMX v2 Connector.

This module provides an adapter for interacting with GMX v2 perpetuals protocol, supporting position management, order execution, and event parsing.

GMX v2 is a decentralized perpetual exchange supporting: - Long and short positions with leverage - Multiple collateral types - Limit and market orders - Position sizing and management

Supported chains: - Arbitrum - Avalanche

Example

from almanak.connectors.gmx_v2 import GMXv2Adapter, GMXv2Config

config = GMXv2Config( chain="arbitrum", wallet_address="0x...", ) adapter = GMXv2Adapter(config)

Open a position¶

Example

config = GMXv2Config( chain="arbitrum", wallet_address="0x...", ) adapter = GMXv2Adapter(config)

Open a long position¶

result = adapter.open_position( market="ETH/USD", collateral_token="USDC", collateral_amount=Decimal("1000"), size_delta_usd=Decimal("5000"), is_long=True, )

Check position¶

position = adapter.get_position( market="ETH/USD", collateral_token="USDC", is_long=True, )

) -> list[GMXv2Position]

Read all open positions for this wallet directly from on-chain state.

Uses the GMX V2 SyntheticsReader contract to query the DataStore for all positions belonging to the configured wallet address. Includes fallback mechanisms for when Reader methods revert (e.g. after GMX contract upgrades).

build_cancel_order_tx ¶

build_cancel_order_tx(order_key: str) -> TransactionData

Build ExchangeRouter.cancelOrder(bytes32) transaction data for an order key.

Pure and stateless: keyed only by the on-chain order_key (bytes32), with no dependency on the adapter's in-memory _orders tracking. This is what the teardown recovery lane (VIB-5568) uses to cancel a discovered stranded order (fresh process, nothing tracked) — unlike :meth:cancel_order, which requires the order to be locally tracked and is blind to teardown-discovered residuals.

value=0 — a cancel carries no keeper execution fee; the OrderVault refund (committed collateral + unspent exec fee) lands in the wallet (cancellationReceiver defaults to the caller).

GMXv2ReceiptParser ¶

GMXv2ReceiptParser(**kwargs: Any)

Parser for GMX v2 transaction receipts.

This parser extracts and decodes GMX v2 events from transaction receipts, providing structured data for position updates, order fills, and other protocol events.

SUPPORTED_EXTRACTIONS declares the extraction fields this parser can provide. Used by ResultEnricher to warn when expected fields are unsupported.

Example

parser = GMXv2ReceiptParser()

Parse a receipt dict (from web3.py)¶

result = parser.parse_receipt(receipt)

if result.success: for event in result.events: print(f"Event: {event.event_name}")

    print(f"Position increased: size=${increase.size_in_usd}")

Initialize the parser.

`**kwargs`	`Any`	Additional arguments (ignored for compatibility).	`{}`

build_extract_kwargs `staticmethod` ¶

extract_swap_amounts ¶

extract_swap_amounts(
    receipt: dict[str, Any],
    *,
    expected_out: Decimal | None = None,
) -> Any

Extract swap amounts from transaction receipt.

GMX V2 "swaps" are executed through perpetual orders, not spot swaps. For GMX orders: - amount_in = initial_collateral_delta_amount (collateral deposited) - amount_out = size_delta_usd (position size in USD, scaled by 1e30) - effective_price represents the leverage ratio

The VIB-3203 expected_out kwarg is accepted for interface parity with spot-swap parsers, but NOT used to compute slippage_bps — comparing "realized collateral" to a "quoted collateral" is not the same semantic as realized vs quoted swap output, and would produce misleading slippage values. Slippage reporting for GMX V2 perps (acceptable price vs execution price) is a separate semantic and is out of scope for VIB-3203.

参数：

名称	类型	描述	默认
`receipt`	`dict[str, Any]`	Transaction receipt dict with 'logs' field	必需
`expected_out`	`Decimal \| None`	Accepted but ignored — see docstring.	`None`

    receipt: dict[str, Any],
) -> Decimal | None

Extract collateral amount from transaction receipt.

参数：

名称	类型	描述	默认
`receipt`	`dict[str, Any]`	Transaction receipt dict with 'logs' field	必需

参数：

名称	类型	描述	默认
`receipt`	`dict[str, Any]`	Transaction receipt dict with 'logs' field	必需

返回：

类型	描述

extract_collateral_returned ¶

extract_collateral_returned(
    receipt: dict[str, Any],
) -> Decimal | None

Extract collateral returned at close from a PERP_CLOSE receipt.

Sums raw collateralDeltaAmount values (the collateral withdrawn from the position) across every PositionDecrease event in the receipt. For a full close GMX sets the delta to the position's entire remaining collateral, so this is the raw collateral-token leg of the close payout. Raw smallest-unit semantics match the other perpetual receipt parsers and allow exact wallet-delta reconciliation without a guessed decimal scale.

Semantics — what this is NOT: the net wallet credit (GMX's outputAmount = collateral delta ± realized PnL − fees, optionally swapped to another token) lives in the EventUtils.EventLogData payload and is distinct from this collateral delta. PnL and fees are extracted separately (realized_pnl, fees_paid).

Empty != Zero: only values the decoder actually produced are summed. Events whose decode fell back to raw_data carry no collateral_delta_amount key and are skipped; if no event carries a decoded value this returns None (unmeasured), never a fabricated zero. A decoded 0 (size-only decrease) is a measured zero and is returned as Decimal("0").

参数：

名称	类型	描述	默认
`receipt`	`dict[str, Any]`	Transaction receipt dict with 'logs' field	必需

返回：

类型	描述
`Decimal \| None`	Total collateral withdrawn across PositionDecrease events, or None
`Decimal \| None`	when no event carries a decoded collateral_delta_amount.

extract_fees_paid ¶

extract_fees_paid(receipt: dict[str, Any]) -> int | None

Extract fees paid from transaction receipt.

参数：

名称	类型	描述	默认
`receipt`	`dict[str, Any]`	Transaction receipt dict with 'logs' field	必需

返回：

类型	描述
`int \| None`	Execution fee in wei if found, None otherwise.

extract_funding_fee_usd_result ¶

extract_funding_fee_usd_result(
    receipt: dict[str, Any],
) -> ExtractResult[Decimal]

Fail-closed variant of :meth:extract_funding_fee_usd — see VIB-3159.

extract_funding_fee_usd ¶

extract_funding_fee_usd(
    receipt: dict[str, Any],
) -> Decimal | None

Extract accumulated funding fee in USD from a CLOSE receipt (VIB-3497).

GMX V2 emits a PositionFeesCollected event alongside every PositionDecrease. The fundingFeeAmount field (collateral-token units) lives inside that event's keyed EventUtils.EventLogData payload. This decodes it BY NAME (VIB-3873) and converts it to USD with the SAME event's collateralTokenPrice bounds — a decimals-free conversion (amount * price / 1e30) that needs no live oracle read, so the parser stays a pure function of the receipt.

Empty != Zero: returns None when the receipt carries no PositionFeesCollected event (or the funding amount / price could not be decoded) — "funding cost unknown" — never a fabricated 0. A measured zero funding fee (short hold) returns Decimal("0").

返回：

类型	描述
`Decimal \| None`	Funding fee in USD, or `None` when unmeasured.

extract_keeper_execution_fee ¶

extract_keeper_execution_fee(
    receipt: dict[str, Any], *, account: str | None = None
) -> tuple[int | None, int | None]

Native-wei (keeper_fee, refund) from a keeper receipt (VIB-6061).

Returns (None, None) when the receipt carries no unambiguous, authentic, account-owned pair — see :meth:_select_execution_fee_events. Never raises: a malformed receipt is unmeasured, not an error, because this rides alongside the fill economics and must never take a settlement write down with it.

extract_perp_fill_result ¶

extract_perp_fill_result(
    receipt: dict[str, Any],
    order_key: str | None = None,
    account: str | None = None,
    index_token_decimals_override: int | None = None,
) -> ExtractResult[PerpFillData]

Fail-closed variant of :meth:extract_perp_fill — see VIB-3159.

account is threaded through (VIB-6061) so this wrapper measures the same fields as the method it wraps. Dropping it here would leave the keeper execution fee unmeasured BY CONSTRUCTION for every caller of the fail-closed variant — a silent divergence between two functions whose whole contract is that they differ only in error handling.

extract_perp_fill ¶

extract_perp_fill(
    receipt: dict[str, Any],
    order_key: str | None = None,
    account: str | None = None,
    index_token_decimals_override: int | None = None,
) -> PerpFillData | None

Build typed fill economics from a GMX keeper receipt (VIB-3872 WI-1).

Merges the receipt's PositionIncrease or PositionDecrease event (position identity, execution price, size / collateral deltas, price impact, realized PnL) with its PositionFeesCollected event (funding / position / borrowing fees in USD). Every field is decoded BY NAME from the keyed EventUtils payload and follows Empty != Zero.

order_key is the settlement being measured (VIB-6110). A GMX keeper transaction may execute SEVERAL orders — on different markets, in different directions — so the position and fee events must be correlated to the watched order rather than taken first-wins. Uncorrelated, closing order B inside a batch that also opened order A returns A's fill: is_open=True with A's market and A's entry price, and B's real exit price is lost. Because the impostor price is itself plausible, nothing downstream can detect the substitution.

Returns None when the receipt carries no PositionIncrease / PositionDecrease event attributable to order_key (nothing to settle) — callers map that to UNMEASURED rather than to a fill. A keeper receipt that only yields the position event (no matching fees event) still returns a PerpFillData with the fee fields left None (unmeasured). Passing order_key=None keeps the legacy first-wins behaviour for callers that have no watched order.

Source authentication. When order_key is supplied, only logs emitted by the chain's canonical GMX EventEmitter are considered. Correlating on an orderKey decoded from an unauthenticated log would not be correlation at all: _parse_log recognises GMX events by topic hash alone and never checks log["address"], and a GMX order carries an owner-chosen callbackContract that runs inside the very keeper transaction this method parses. A co-batched adversary can read the order nonce from DataStore, compute our key, and emit a forged PositionDecrease carrying it with an arbitrary market and price — moving the attack from "be first in the log list" to "write the right 32 bytes". Restricting to the EventEmitter is what makes the decoded orderKey trustworthy. If the emitter cannot be resolved (unknown or absent chain) a correlated call fails closed to None: an unmeasured settlement is recoverable, a forged one is not.

The emitter check runs against each PARSED event's contract_address (see :meth:_select_fill_events), never by pre-filtering the receipt's logs — a filtered receipt keeps its transactionHash, which is the key ResultEnricher's parse cache uses, so pre-filtering is defeatable by a warmed cache.

account (VIB-6061) is the strategy wallet. Supplying it additionally measures the keeper execution fee — the native-token cost of the fill that is NOT transaction gas and that the Cost Stack previously showed nowhere. Omitting it leaves keeper_execution_fee_wei unmeasured; it never affects the fill economics above.

extract_protocol_fees ¶

extract_protocol_fees(_receipt: dict[str, Any]) -> None

Placeholder for GMX V2 perp-fee extraction (VIB-3204).

GMX V2 encodes open / close fees in PositionFeesInfo events emitted by the position handler. Decoding those events (including borrowing, funding, and execution-fee components) is non-trivial and is deferred to a follow-up; extract_fees_paid already surfaces the execution fee in wei for operator-level accounting.

Follow-up ticket: "Perps fee extraction for GMX V2 / Drift — follow-up to VIB-3204".

PerpFillData `dataclass` ¶

PerpFillData(
    is_open: bool | None = None,
    is_long: bool | None = None,
    market: str | None = None,
    collateral_token: str | None = None,
    position_key: str | None = None,
    order_key: str | None = None,
    entry_price: Decimal | None = None,
    exit_price: Decimal | None = None,
    size_delta_usd: Decimal | None = None,
    size_delta_in_tokens: Decimal | None = None,
    collateral_delta_amount: Decimal | None = None,
    price_impact_usd: Decimal | None = None,
    realized_pnl_usd: Decimal | None = None,
    position_fee_usd: Decimal | None = None,
    funding_fee_usd: Decimal | None = None,
    borrowing_fee_usd: Decimal | None = None,
    keeper_tx_hash: str | None = None,
    block_number: int | None = None,
    keeper_execution_fee_wei: int | None = None,
    execution_fee_refund_wei: int | None = None,
)

Receipt-measured GMX V2 fill economics (VIB-3873 / VIB-3872 WI-1).

Built from a keeper transaction's PositionIncrease or PositionDecrease event, merged with its PositionFeesCollected event, each decoded BY KEY from the dynamic EventUtils.EventLogData payload (not fixed byte offsets — that is the VIB-3873 misread class). This is the typed verdict payload the WI-2 settlement capability carries into accounting; it is intentionally self-contained (no framework imports) so WI-2 can consume it without new plumbing.

Empty != Zero — every field is Optional. None means the keeper receipt did not carry that field (unmeasured); Decimal("0") means a measured zero (e.g. zero funding over a short hold). Never substitute one for the other.

Scaling:

size_delta_usd / price_impact_usd / realized_pnl_usd are plain USD Decimals (GMX's 30-decimal USD convention divided out).
position_fee_usd / funding_fee_usd / borrowing_fee_usd are plain USD, converted from the fee's collateral-token amount using the SAME PositionFeesCollected event's collateralTokenPrice (decimals-free: amount * price / 1e30).
entry_price / exit_price are USD-per-token: GMX executionPrice scaled by 10**(index_token_decimals) / 1e30 (VIB-6110). The index-token decimals are resolved from the parser's chain + the fill's market via the venue-verified catalog. Empty≠Zero: None when the price is absent OR the decimals cannot be resolved (parser constructed without a chain, or an unlisted market) — NEVER the wrongly-scaled raw GMX-native ratio (the 1.9e-15 bug this field previously shipped).
collateral_delta_amount is the raw collateral-token smallest-unit integer (matches extract_collateral_returned semantics — no guessed decimal scale).
keeper_execution_fee_wei / execution_fee_refund_wei are NATIVE-token wei integers, not USD (VIB-6061). They are the two halves of the escrow we posted as msg.value at createOrder: the keeper's cut and our refund. Kept in wei rather than converted here because the parser is a pure function of the receipt and holds no price oracle — the USD conversion happens at the settlement-commit seam against the SUBMISSION row's own price_inputs_json, so the booked USD is priced at the same moment as that row's gas_usd.

to_dict ¶

to_dict() -> dict[str, Any]

Convert to a stable machine-readable dictionary (Empty != Zero preserved).

get_allowed_collaterals ¶

get_allowed_collaterals(
    chain: str, market: str
) -> tuple[str, ...]

Return the tuple of allowed collateral token symbols for a market.

参数：

名称	类型	描述	默认
`chain`	`str`	Chain name (`"arbitrum"` or `"avalanche"`). Case-insensitive.	必需
`market`	`str`	Canonical venue market label (e.g. `"ETH/USD"`). Case-insensitive.	必需

返回：

类型	描述
`str`	Tuple of allowed collateral symbols. The tuple is non-empty for any
`...`	registered `(chain, market)` pair.

引发：

类型	描述
`KeyError`	If the market is not registered for the chain. Callers that want the "unknown market" path should call :func:`is_market_registered` first.

is_market_registered ¶

is_market_registered(chain: str, market: str) -> bool

Return True if collateral rules are known for (chain, market).

Used by the compiler to distinguish between "market is unknown, cannot validate locally" (permissive path) and "market is known and the collateral is wrong" (strict reject path).

Chain and market inputs are case-insensitive.

registered_markets ¶

registered_markets(chain: str) -> Iterable[str]

Return the iterable of market identifiers registered for a chain.

Useful for diagnostics / operator card messages. Chain input is case-insensitive.

validate_collateral ¶

validate_collateral(
    chain: str, market: str, collateral_token: str
) -> None

Validate that collateral_token is a legal collateral for market.

Compile-path validation. This is the main entry point used by the _compile_perp_open path in the intent compiler. It must be called BEFORE any transaction actions are emitted.

Behaviour

If market is registered for chain and collateral_token is not one of the allowed symbols, raise :class:InvalidCollateralForMarketError.
If market is registered and collateral_token is recognised but passed as a raw 0x-address, the validation is skipped with a debug log and the compiler falls through to address-based resolution.
If market is NOT registered (unknown / new market), log a warning and return (permissive). The strict on-chain check still fires at order-time via the GMX keeper, but this module cannot do better without an RPC round trip.

参数：

名称	类型	描述	默认
`chain`	`str`	Chain name (`"arbitrum"` or `"avalanche"`). Case-insensitive.	必需
`market`	`str`	Market identifier (e.g. `"ETH/USD"`). Case-insensitive.	必需
`collateral_token`	`str`	Collateral token symbol (e.g. `"USDC"`) or 0x-address. Comparison is case-insensitive for symbols; raw addresses are detected case-insensitively (`0x...` or `0X...`).	必需

引发：

类型	描述
`InvalidCollateralForMarketError`	When both the market is registered AND the collateral is a symbol that is not in the allowed set.

get_gmx_v2_sdk ¶

get_gmx_v2_sdk(
    rpc_url: str | None = None,
