# Send Solana Legacy Transaction

```ts React Native theme={"system"}
    import { dynamicClient } from '<path to client file>'
    import { PublicKey, SystemProgram, Transaction } from '@solana/web3.js'

    const wallet = dynamicClient.wallets.primary
    if (!wallet) {
    // user is not connected yet
    } else {
    const connection = dynamicClient.solana.getConnection()
    const signer = dynamicClient.solana.getSigner({ wallet })

    const fromKey = new PublicKey(wallet.address)
    const toKey = new PublicKey('<destinationAddress>')
    const amountInLamports = 1_000_000_000 // 1 SOL

    const tx = new Transaction().add(
        SystemProgram.transfer({ fromPubkey: fromKey, toPubkey: toKey, lamports: amountInLamports })
    )

    const { blockhash } = await connection.getLatestBlockhash()
    tx.recentBlockhash = blockhash
    tx.feePayer = fromKey

    const { signature } = await signer.signAndSendTransaction(tx)
    console.log('Successful transaction signature:', signature)
    }
```

## Simulate a Transaction

Before sending a transaction, you can simulate it to preview the effects and validate that it will succeed. Transaction simulation shows all asset transfers involved in the transaction.

<Note>
  Transaction simulation uses the currently selected primary wallet. Make sure the user has a wallet connected before attempting to simulate a transaction.

```ts React Native theme={"system"}
    import { dynamicClient } from '<path to client file>'
    import { PublicKey, SystemProgram, Transaction, LAMPORTS_PER_SOL } from '@solana/web3.js'

    const simulateSolanaLegacyTransaction = async (to: string, amountSol: number) => {
      const connection = dynamicClient.solana.getConnection()

      const fromKey = new PublicKey(dynamicClient.wallets.primary.address)
      const toKey = new PublicKey(to)
      const amountInLamports = Math.round(amountSol * LAMPORTS_PER_SOL)

      const tx = new Transaction().add(
        SystemProgram.transfer({ fromPubkey: fromKey, toPubkey: toKey, lamports: amountInLamports })
      )

      const { blockhash } = await connection.getLatestBlockhash()
      tx.recentBlockhash = blockhash
      tx.feePayer = fromKey

      const simulationResult = await dynamicClient.solana.simulateSVMTransaction({
        transaction: tx,
        type: 'SignTransaction',
      })

      console.log('Simulation result:', simulationResult)
      return simulationResult
    }
```
