Learn how to reliably send and confirm Solana transactions using Helius infrastructure. Staked connections, priority fees, and enterprise-grade reliability.
Sending transactions is a fundamental part of interacting with the Solana blockchain. Whether you’re executing a trade on a DEX, minting an NFT, transferring assets, or calling a smart contract, a robust transaction-sending strategy is crucial for any application.Helius provides powerful infrastructure and tools to ensure your transactions are submitted optimally, confirmed quickly, and delivered with the highest reliability.
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 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.
