Default EIP-2930 addresses to add when simulating the transaction initially

### finalityCheckStrategy?

```
optional finalityCheckStrategy: object;
```

Defined in: [atomiq-chain-evm/src/evm/chain/EVMChainInterface.ts:86](https://github.com/atomiqlabs/atomiq-chain-evm/blob/98ca6f16fbfb37e521f8c27b4f942642fe00c2ee/src/evm/chain/EVMChainInterface.ts#L86)

Strategy for checking finality of transactions or events

#### delayMs?

```
optional delayMs: number;
```

Interval in milliseconds to use for the `"timer"` type of finality checking strategy

#### type

```
type: "timer" | "blocks";
```

Type of the finality checking strategy:

* `"timer"` - periodically checks for the finality status, set the interval period `delayMs`
* `"blocks"` - check for the finality when new block is created
