Accepts an same argument that is Solana's Connection class second argument. |
| `simulateSVMTransaction` | `(params: { transaction: Transaction \| VersionedTransaction; type: 'SignTransaction' \| 'SendTransaction' }) => Promise<SimulateTransactionResponse>` | Simulates a Solana transaction to preview effects before sending. Supports both legacy and versioned transactions. Uses the primary wallet.       |

## Types

### `ISolanaExtension` type

Type of the solana extension.

```typescript theme={"system"}
import {
  Connection,
  PublicKey,
  SendOptions,
  Transaction,
  TransactionSignature,
  VersionedTransaction,
} from '@solana/web3.js'

import { type Wallet } from '@dynamic-labs/client'

type SignedMessage = {
  signature: Uint8Array
}

type ISolanaSigner = {
  publicKey: PublicKey
  signTransaction<T extends Transaction | VersionedTransaction>(
    transaction: T
  ): Promise<T>
  signAllTransactions<T extends Transaction | VersionedTransaction>(
    transactions: T[]
  ): Promise<T[]>
  signAndSendTransaction<T extends Transaction | VersionedTransaction>(
    transaction: T,
    options?: SendOptions
  ): Promise<{ signature: TransactionSignature }>
  signMessage(message: Uint8Array, encoding?: string): Promise<SignedMessage>
}

type ISolanaExtension = {
  solana: {
    getConnection: (
      connectionConfig?: ConnectionConfig | Commitment
    ) => Connection
    getSigner: (props: { wallet: Wallet }) => ISolanaSigner
  }
}
```
