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(bytecode, abi, wallet);
const contract = await factory.deployContract({
  storageSlots,
  gasPrice: minGasPrice,
});

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 contract = await factory.deployContract({
  gasPrice,
  storageSlots: [

      value: '0000000000000001000000000000000000000000000000000000000000000000',
    },
    {
