SOL Stripe and Jito Labs launch the FullSend routing system to help Solana transactions faster and more reliable.
Stripe\'s acquisition of crypto wallet infrastructure company Priy in 2025 has begun to bear fruit: Priy teamed up with Solana infrastructure provider Jito Labs to jointly launch a new transaction routing system called FullSend. This innovative solution aims to make transaction confirmations on the Solana blockchain faster and more reliable, thereby improving the operating efficiency of the entire network.
Directly routed to block producers
According to the company\'s statement, since the beginning of this year, FullSend has been quietly integrated into the Privy wallet. During this period, FullSend performed well, successfully incorporating 99.999% of transactions in millions of trading attempts.
The FullSend system routes transactions signed via the Privy wallet directly to Solana\'s current and next block leaders through Jito\'s low-latency network. Since block producers on Solana rotate approximately every 400 milliseconds, getting transactions to the right verification node at the right time is critical for timely confirmation of transactions.
Traditionally, transactions have been propagated through public or managed RPC nodes, which serve as intermediaries for network communications. FullSend removes these intermediate links and sends transactions directly to block leaders. The company reports that by bypassing this layer, transaction confirmation latency can be reduced to approximately 50 milliseconds, compared to 200 milliseconds or more for traditional routing methods.
Note: An RPC node is a technology access point that allows wallets and applications to communicate with the blockchain network. MEV refers to the strategy of extracting additional revenue from observed transactions before block generation, including preemptive transactions and transaction reordering.
Streamline complex operations for developers
Asta Li, Chief Technology Officer of Priy, emphasized that the core goal of FullSend is to reduce the complexity developers face when dealing with priority fees, additional network incentives, and endpoint selection.
Privy leadership pointed out that FullSend aims to reduce the burden on developers and simplify their process of balancing priority fees, additional incentives, and connection management across the network.
Jito Labs said its infrastructure can reliably send transactions directly to the verification node responsible for generating the next block. This approach helps users maintain standard priority fees and reduces their risk of being attacked by automated robots targeting pending transactions.
Enhance protection against MEV attacks
Both companies claim that FullSend provides additional protection against common MEV attack vectors, including preemptive transactions, sandwich attacks, and transaction censorship. As Solana-based applications increasingly require speed and accuracy, protection at the infrastructure level has become increasingly important.
Lucas Bruder, CEO of Jito Labs, emphasized that speed and reliability are now core requirements for Solana applications. He said that by routing directly to block leaders, FullSend improves performance while also providing native MEV protection.
Stripe continues to expand its cryptographic infrastructure landscape
This move marks the latest chapter in Stripe\'s continued expansion in the field of cryptographic infrastructure. The payment technology giant acquired Priy in 2025, and earlier this year, Priy announced a partnership with Alchemy to attract institutional users.
Privy said its infrastructure now serves well-known financial technology companies including Klarna, Ramp and Deel, as well as crypto trading platforms such as Hyperliquid. The company said it supports more than 140 million accounts with monthly transaction volume reaching billions of dollars. At the same time, Stripe is also expanding its investment in blockchain payment systems-most notably, it is developing the Layer 1 blockchain Tempo, which focuses on stablecoins.
