Canceling orders

[!WARNING]

These code snippets are just examples and the data should never be used as is

Cancel orders using order nonces​

This method is used to invalidate the orderNonce. If multiple maker orders share the same nonce, they will all be cancelled and non-executable. An orderNonce is also invalidated once an order with that nonce is executed.

import {
  HypercertExchangeClient,
  ChainId,
} from "@hypercerts-org/marketplace-sdk";

const hypercertExchangeClient = new HypercertExchangeClient(
  ChainId.OPTIMISM,
  provider,
  signer
);

// Cancel order nonce 0
const tx = await hypercertExchangeClient.cancelOrders([0]).call();
const receipt = await tx.wait();

// Cancel order nonce 0 and 12
const tx = await hypercertExchangeClient.cancelOrders([0, 12]).call();
const receipt = await tx.wait();

Cancel all your bids and/or all your asks​

This function can be used to cancel all the sender's bids or all the sender's asks, or both in a single call. The following example showcases all the possible combinations.

import {
  HypercertExchangeClient,
  ChainId,
} from "@hypercerts-org/marketplace-sdk";

const hypercertExchangeClient = new HypercertExchangeClient(
  ChainId.OPTIMISM,
  provider,
  signer
);

// Cancel all bids
const tx = await hypercertExchangeClient.cancelAllOrders(true, false).call();
const receipt = await tx.wait();

// Cancel all asks
const tx = await hypercertExchangeClient.cancelAllOrders(false, true).call();
const receipt = await tx.wait();

// Cancel all bids and asks
const tx = await hypercertExchangeClient.cancelAllOrders(true, true).call();
const receipt = await tx.wait();
