Privy, the crypto wallet infrastructure company owned by Stripe, has partnered with Solana infrastructure provider Jito Labs to launch FullSend, a new transaction routing system designed to improve the speed and reliability of transactions on the Solana blockchain.
The companies said the tool has already been running quietly in production inside Privy wallets since the beginning of the year. During that period, FullSend achieved a 99.999% transaction landing rate across millions of transactions.
Stripe 旗下钱包基础设施公司 Privy 与 Solana 基础设施公司 Jito Labs 联合推出交易加速工具 FullSend，可将 Privy 钱包签名的交易直接路由至 Solana 当前区块生产者，以提升交易确认速度和成功率。官方表示，该工具自今年 1 月起已在 Privy 钱包中运行。Privy 于 2025 年被 Stripe 收购，目前服务…

How does FullSend improve Solana transactions?
FullSend automatically routes transactions signed through Privy wallets directly to Solana’s current and upcoming block leaders using Jito’s low-latency network. Solana changes its block producers approximately every 400 milliseconds, making speed critical for successful transaction inclusion.
Instead of relying on public or hosted RPC nodes to broadcast transactions, FullSend sends them directly to block leaders. According to the companies, this reduces transaction inclusion latency to about 50 milliseconds, compared with the roughly 200 milliseconds or more required through traditional routing methods.
Privy Chief Technology Officer Asta Li said the goal was to remove the complexity developers face when choosing priority fees, tips and network endpoints.

Can the tool reduce MEV risks?
The companies said FullSend also helps protect users from common Maximal Extractable Value (MEV) attacks, including front-running, sandwich attacks and transaction censorship.
Jito Labs’ infrastructure delivers transactions directly to validators responsible for producing the next blocks, allowing users to keep standard priority fees while reducing exposure to bots that exploit pending transactions.
Jito Labs CEO Lucas Bruder said transaction speed and reliability have become essential for applications built on Solana, adding that FullSend delivers direct routing to block leaders with built-in MEV protection.
Stripe expands its crypto infrastructure strategy
The launch adds to Stripe’s growing presence in crypto infrastructure following its acquisition of Privy in 2025. Earlier this year, Privy also partnered with Alchemy to provide institutional onboarding services.
Privy says its infrastructure supports fintech companies, including Klarna, Ramp, and Deel, as well as the crypto trading platform Hyperliquid. The company claims more than 140 million accounts use its technology, processing billions of dollars in monthly transaction volume.
Stripe is also developing the stablecoin-focused Layer-1 blockchain Tempo, expanding its investment in blockchain-based payment infrastructure.
