@somnia-chain/markets-sdk / index / PlaceSpotOrderParams

Interface: PlaceSpotOrderParams

Defined in: packages/sdk/src/trade.ts:415

Inputs to Trader.placeSpotOrder — a spot limit or market order on a SpotPool.

Properties

pool

pool: `0x${string}`

Defined in: packages/sdk/src/trade.ts:417

SpotPool address.

isBid

isBid: boolean

Defined in: packages/sdk/src/trade.ts:419

True = buy the base asset (pay quote); false = sell base (pay base/native).

price

price: bigint

Defined in: packages/sdk/src/trade.ts:424

Limit price — raw quote units per whole base token. For a MARKET order pass a crossing price (best opposite level ± slippage); it bounds the escrow.

quantity

quantity: bigint

Defined in: packages/sdk/src/trade.ts:426

Base quantity, raw base units.

baseDecimals?

optional baseDecimals?: number

Defined in: packages/sdk/src/trade.ts:433

Base-token decimals. The pool now reports its exact funding requirement, so the SDK no longer uses this value.

Deprecated

Retained for source compatibility. New calls can omit it.

quoteToken

quoteToken: `0x${string}`

Defined in: packages/sdk/src/trade.ts:435

Quote token (approved on a buy).

baseToken

baseToken: `0x${string}`

Defined in: packages/sdk/src/trade.ts:437

Base token (approved on a non-native sell).

baseIsNative?

optional baseIsNative?: boolean

Defined in: packages/sdk/src/trade.ts:445

True when the base asset is native SOMI. A sell then pays via msg.value instead of an approval — the pool's exact vault shortfall, fee headroom included, read from getAutoPullRequirement (one eth_call) right before the order is encoded. The bare quantity would revert InvalidMsgValue on any fee-bearing pool.

expireTimestampNs?

optional expireTimestampNs?: bigint

Defined in: packages/sdk/src/trade.ts:461

Order expiry in ns. Defaults to ~50y (GTC). A spot pool has no market expiry to outlive, so the binary verb's OrderExpiryBeyondMarket cap does not apply here.

Two traps:

  • A timestamp already in the PAST reverts with OrderAlreadyExpired. It used to be accepted silently — the pool skipped the placement and returned no order id, so the transaction succeeded having placed nothing — but the current protocol rejects it outright.
  • An expired order does NOT auto-return its escrow, and this one IS silent. The funds stay locked in the pool until someone sweeps it — Trader.cancelExpiredOrders reclaims them, and is callable by anyone, not only the owner.

orderType?

optional orderType?: number

Defined in: packages/sdk/src/trade.ts:463

0 limit (default) or 2 market (IOC). See ORDER_TYPE.

selfMatchingOption?

optional selfMatchingOption?: number

Defined in: packages/sdk/src/trade.ts:468

Self-match behaviour when this order crosses your OWN resting order, default 0 (CANCEL_TAKER). See SELF_MATCHING_OPTION.

userData?

optional userData?: bigint

Defined in: packages/sdk/src/trade.ts:470

Opaque market-maker bookkeeping tag, forwarded verbatim. Default 0.

autoApprove?

optional autoApprove?: boolean

Defined in: packages/sdk/src/trade.ts:472

Approve the escrow token if allowance is short (default true).

builder?

optional builder?: `0x${string}`

Defined in: packages/sdk/src/trade.ts:478

Routing/builder frontend address to attribute the order to. Requires the trader to have opted this builder in via Trader.approveBuilder on this pool. Omit (or zero) for no routing fee.

builderFeeBpsTimes1k?

optional builderFeeBpsTimes1k?: bigint

Defined in: packages/sdk/src/trade.ts:485

Per-order builder/routing fee in the pool's native bps×1000 unit (≤ the pool's maxBuilderFee ceiling AND ≤ the trader's approval). 0 = none. The ceiling is owner-updatable on a SpotPool, so read it rather than caching it indefinitely.

gas?

optional gas?: bigint

Defined in: packages/sdk/src/trade.ts:491

Gas ceiling for this tx.

Default

TraderConfig.gas (10,000,000)
