# Sending transactions methods

Solana transaction methods: sendTx, sendTransaction, simulateTransaction, getFeeForMessage, getRecentPrioritizationFees, and the Titan swap API.

## Submit and simulate

| Method                                                                                   | What it does                                                          |
| ---------------------------------------------------------------------------------------- | --------------------------------------------------------------------- |
| [`sendTx`](/solana/rpc-methods/sending-transactions/sendtx.md)                           | Direct HTTP submission endpoint that bypasses JSON-RPC.               |
| [`sendTransaction`](/solana/rpc-methods/sending-transactions/sendtransaction.md)         | Submits a signed transaction over JSON-RPC and returns its signature. |
| [`simulateTransaction`](/solana/rpc-methods/sending-transactions/simulatetransaction.md) | Runs a transaction against chain data without sending it.             |

## Fees

| Method                                                                                                   | What it does                                               |
| -------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------- |
| [`getFeeForMessage`](/solana/rpc-methods/sending-transactions/getfeeformessage.md)                       | The fee the cluster would charge to process a message.     |
| [`getRecentPrioritizationFees`](/solana/rpc-methods/sending-transactions/getrecentprioritizationfees.md) | Recent priority-fee samples for setting a competitive fee. |

To build swap transactions, see the [Titan](/solana/rpc-methods/sending-transactions/titan.md) swap API.
