executeTransaction

Executes a single transaction step with the provided transaction data. This method is used internally by executeQuote but can also be used directly for more granular control over transaction execution.

interface ExecuteTransactionParams {
  txDataResponse: TransactionDataResponse;
  quote: Quote;
  step: TransactionStep;
  provider: BrowserProvider | WalletClient;
  walletAdapter: WalletAdapter;
  cosmosClient: SigningStargateClient | SigningCosmWasmClient;
  solanaRpcUrl?: string;
}

// Example implementation
const txnResponse = await getNextTxn({
  routeId: quote.routeId,
  stepId: step.stepId,
});
// Example implementation
const txHash = await executeTransaction({
  txDataResponse,
  quote,
  step,
  provider: ethersProvider,
  walletAdapter: solanaWallet,
  cosmosClient: cosmosClient,
  solanaRpcUrl: "https://api.mainnet-beta.solana.com",
});

The method handles different transaction types based on the network:

• For EVM chains: Supports regular transactions for on chain transactions, EIP-712 typed data signing for gasless transactions, and untyped message signing for meson finance transactions.

• For Solana: Handles Solana-specific transaction formats

• For Cosmos: Manages Cosmos SDK transaction types

The provider, walletAdapter, and cosmosClient parameters are mutually exclusive - you should provide the appropriate one based on the chain you're interacting with:

• For EVM chains: provide the provider parameter

• For Solana: provide the walletAdapter parameter

• For Cosmos chains: provide the cosmosClient parameter

The method returns the transaction hash of the executed transaction, which can be used to monitor its status using checkStatus or pollTransactionStatus.
