Stripe and Jito Labs have jointly launched the FullSend routing system, designed to dramatically improve transaction speed and reliability on the Solana network. By routing transactions directly to current and upcoming block leaders, the system cuts through traditional RPC node intermediaries, reducing inclusion latency to approximately 50 milliseconds — compared to over 200 milliseconds via conventional methods.
Direct Routing to Block Producers
According to company statements, FullSend has been quietly integrated into Privy wallets since early this year. During testing, the system achieved a 99.999% success rate across millions of transaction attempts. FullSend leverages Jito’s low-latency network to deliver Privy-signed transactions directly to Solana’s block leaders. Since block producers on Solana rotate roughly every 400 milliseconds, delivering transactions to the right validator at the right moment is crucial. Traditionally, transactions propagate through public or hosted RPC nodes that act as intermediaries; FullSend eliminates these middlemen, significantly cutting latency.
Streamlining Developer Complexity
Privy CTO Asta Li emphasized that FullSend’s core goal is to reduce the complexity developers face when balancing priority fees, extra network incentives, and endpoint selection. Jito Labs noted its infrastructure reliably gets transactions directly to validators responsible for producing upcoming blocks, helping users maintain standard priority fees and reducing exposure to automated front-running bots.
Enhanced MEV Attack Protection
Both companies claim FullSend provides additional safeguards against common MEV attack vectors, including front-running, sandwich attacks, and transaction censorship. As speed and precision become more critical in Solana-based applications, infrastructure-level protections are increasingly vital. Jito Labs CEO Lucas Bruder stated that speed and reliability are now core requirements for Solana apps, and that FullSend delivers native MEV protection alongside improved performance by routing directly to block leaders.
Stripe's Expanding Crypto Infrastructure Footprint
This move marks the latest chapter in Stripe’s growing presence in crypto infrastructure. The payments giant acquired Privy in 2025, and earlier this year Privy announced a collaboration with Alchemy to onboard institutional users. Privy reports its infrastructure is used by major fintech firms such as Klarna, Ramp, and Deel, along with crypto trading platforms like Hyperliquid, supporting over 140 million accounts and handling billions of dollars in monthly transaction volume. Meanwhile, Stripe is broadening investments in blockchain-based payment systems, most notably developing the stablecoin-focused Layer 1 blockchain, Tempo.
