SeriesNonceManager predicate

Make sure you have read and understand


Since Limit Order Protocol V3 nonce management are delegated to SeriesNonceManager smart contract in terms of usual Limit Orders and P2P (aka "private limit order"), there are two helpful classes:

  • SeriesNonceManagerFacade — an interface for interacting with smart contract
  • SeriesNonceManagerPredicateBuilder — an LimitOrderPredicateBuilder-compatible DSL for building predicate, which relays on SeriesNonceManager

SeriesNonceManagerFacade​

See nonce


SeriesNonceManagerPredicateBuilder​

Partially implements LimitOrderPredicateBuilder for same purpose, but for SeriesNonceManager smart contract.

Incompatible with Gasless!

For Gasless orders use LimitOrderPredicateBuilder.


Built-in operators​

timestampBelowAndNonceEquals​

timestampBelowAndNonceEquals(
    timestamp: number | bigint,
    makerNonce: number | bigint,
    makerAddress: string
)

The predicate checks the same as and(timestampBelow(), nonceEquals()).

nonceEquals​

nonceEquals(
    makerAddress: string,
    makerNonce: number | bigint
)

The predicate checks that the makerNonce is equal to the nonce of makerAddress.

WARNING!

To save gas consider using one of

instead as it more optimal then separate and(timestampBelow(), nonceEquals()) calls.


Examples​

// Because timestampBelowAndNonceEquals is method of another contract arbitraryStaticCall() is necessary
const simpleLimitOrderPredicate: LimitOrderPredicateCallData = arbitraryStaticCall(
    seriesNonceManagerPredicateBuilder.facade,
    seriesNonceManagerPredicateBuilder.timestampBelowAndNonceEquals(
        NonceSeriesV2.LimitOrderV3,
        expiration,
        nonce,
        walletAddress,
    ),
);

See LimitOrderPredicateBuilder for more examples on using LimitOrderPredicateBuilder and SeriesNonceManagerPredicateBuilder together.
