Storage Slots

When deploying a contract, you can specify the custom storage slots that you want to use.

import storageSlots from '../your-sway-project/out/debug/your-sway-project-storage_slots.json';

const factory = new ContractFactory(
  StorageTestContractFactory.bytecode,
  StorageTestContract.abi,
  wallet
);
const deploy = await factory.deploy({
  storageSlots,
});

const { contract } = await deploy.waitForResult();

Using plain JavaScript

In the above example, we directly imported the storage slots from a JSON file generated by the Sway compiler.

Instead of importing from a file, you can also specify the custom storage slots directly in your code:

const { waitForResult } = await factory.deploy({
  storageSlots: [
    {

      value: '0000000000000001000000000000000000000000000000000000000000000000',
    },
    {
      key: '6294951dcb0a9111a517be5cf4785670ff4e166fb5ab9c33b17e6881b48e964f',

  ],
});
const { contract } = await waitForResult();
