# Solana Transaction Sending

> Learn how to reliably send and confirm Solana transactions using Helius infrastructure. Staked connections, priority fees, and enterprise-grade reliability.

## Why is transaction sending hard on Solana?

Every interaction with Solana — trading on a DEX, minting an NFT, transferring tokens, or calling a program — requires a transaction that lands onchain. During network congestion, unoptimized transactions are frequently dropped before reaching a leader. Helius provides staked connections that route directly to leaders, priority fee optimization, and enterprise-grade redundancy to ensure your transactions confirm quickly and reliably.

## Transaction Sending Options

We offer multiple pathways for sending transactions, each designed for different needs and use cases.

## What is the difference between staked and unstaked connections?

Helius offers both staked and unstaked connections for sending transactions.

* **Staked Connections (Recommended)**: When you send transactions through our endpoints (available on paid plans), your transactions are routed directly to the current and upcoming block leaders. This provides a priority lane, bypassing the public transaction processing queue and offering near-guaranteed delivery. Using the Helius [Priority Fee API](/priority-fee-api) ensures you pay the optimal fee required by the leader.

* **Unstaked Connections**: On our free plan, transactions are sent through high-performance, but unstaked, RPC nodes. They are subject to the same network congestion and competition for leader processing as any other public transaction.

For any production application, using **staked connections is the single most effective way to ensure reliable transaction delivery.**
