SDK Actions

A number of SDK methods return actions. These actions can be one of two types:

• ActionType.TRANSACTION - an action that is executed when a transaction is sent to the blockchain
• ActionType.SIGNABLE - an action that is executed when a message is signed and submitted through a subsequent SDK call

Actions are returned in order, so it is safe to iterate over them. The following code block is an example of how one might execute all actions:

import { providers } from 'ethers';
import { orderbook } from '@imtbl/sdk';

// Sign and submit all transaction actions. Collect and return all signatures from signable actions.
export async function actionAll(
  actions: orderbook.Action[],
  provider: providers.Web3Provider,
): Promise<string[]> {
  const signer = await provider.getSigner()

  const signatures: string[] = [];
  for (const action of actions) {
    if (action.type === orderbook.ActionType.TRANSACTION) {
      const transaction = await action.buildTransaction();
      const signedTx = await signer.sendTransaction(transaction);
      await signedTx.wait();
    }
    if (action.type === orderbook.ActionType.SIGNABLE) {
      const signature = await signer._signTypedData(
        action.message.domain,
        action.message.types,
        action.message.value,
      );

      signatures.push(signature);
    }
  }

  return signatures;
}
