sendTransaction RPC Method

You can protect your transactions from toxic MEV threats like sandwich attacks and front-running by enabling MEV protection. To know more on how to enable it, check out our MEV Protection documentation. For an in-depth guide on MEV, see What is MEV (Maximum Extractable Value) and How to Protect Your Transactions on Solana.
