Summary

Signer for Rango Solana Transactions

Currecntly all Rango Solana transactions are Versioned (and serialized), only Solana Wrapper is already using the legacy format. (which is used only for SOL <-> WSol routes)

Versioned Transaction Sign Flow Overview:

1. Get connection and recent blockhash

   const connection = new Connection(SOLANA_RPC_URL, {
     commitment: 'confirmed',
     disableRetryOnRateLimit: false,
   });
   const latestBlock = await connection.getLatestBlockhash('confirmed');

2. Prepare the transaction

   const transaction = VersionedTransaction.deserialize(
     new Uint8Array(tx.serializedMessage)
   );
   transaction.message.recentBlockhash = recentBlockhash;

3. Simulate the transaction

   const { value } = await connection.simulateTransaction(transaction, {
     replaceRecentBlockhash: true,
     commitment: 'processed',
   });

4. Sign the transaction

   const signedTransaction = await solanaProvider.signTransaction(
     solanaWeb3Transaction
   );
   const serializedTransaction = Buffer.from(signedTransaction.serialize());

5. Send and confirm the transaction (similar to jupiter suggested code)

   const { txId, txResponse } = await transactionSenderAndConfirmationWaiter({
     connection,
     serializedTransaction,
   });
