If the hash does not match, an error is returned. If this field is set, then appData MUST be a string encoding of a JSON object. |
buyAmount | TokenAmount | see OrderParameters::buyAmount |
buyToken | Address | see OrderParameters::buyToken |
buyTokenBalance? | BuyTokenDestination | see OrderParameters::buyTokenBalance |
feeAmount | TokenAmount | see OrderParameters::feeAmount |
from? | Address | null | If set, the backend enforces that this address matches what is decoded as the signer of the signature. This helps catch errors with invalid signature encodings as the backend might otherwise silently work with an unexpected address that for example does not have any balance. |
kind | OrderKind | see OrderParameters::kind |
partiallyFillable | boolean | see OrderParameters::partiallyFillable |
quoteId? | number | null | Orders can optionally include a quote ID. This way the order can be linked to a quote and enable providing more metadata when analysing order slippage. |

invalidated | boolean | Has this order been invalidated? |
isLiquidityOrder? | boolean | Liquidity orders are functionally the same as normal smart contract orders but are not placed with the intent of actively getting traded. Instead they facilitate the trade of normal orders by allowing them to be matched against liquidity orders which uses less gas and can have better prices than external liquidity. As such liquidity orders will only be used in order to improve settlement of normal orders. They should not be expected to be traded otherwise and should not expect to get surplus. |
onchainOrderData? | OnchainOrderData | There is some data only available for orders that are placed on-chain. This data can be found in this object. |
