Stripe’s Privy and Jito launch FullSend for faster Solana transaction inclusion

Stripe subsidiary Privy has partnered with Solana infrastructure firm Jito Labs to launch FullSend, a transaction-routing tool designed to help Privy wallet transactions reach Solana block producers more reliably by sending them directly to whichever validator is building the next block. The integration sits inside Privy’s wallet infrastructure, so transactions signed through both externally-owned accounts and embedded wallets are routed automatically without developers adding custom logic. The new article describes FullSend as bypassing the usual path through RPC nodes, which can add latency and contribute to dropped or delayed transactions during congestion. It says Jito operates Solana’s primary MEV block engine and leader auction systems, and that its modified validator client runs on a majority of the network’s stake, giving it a central role in how transactions are prioritized and included. Previously disclosed launch details said FullSend has been running in production inside Privy since January, achieving 99.999% landing reliability across millions of transactions and cutting inclusion latency to 50 milliseconds from at least 200 milliseconds under the traditional broadcast process. The companies had also said the setup helps reduce MEV-related risks such as front-running, sandwiching and censorship. The latest report adds that FullSend tackles execution reliability at the application layer rather than through protocol changes, allowing deployment without waiting for network-wide validator upgrades. It also highlights a concentration risk: deeper wallet-level dependence on Jito could expand the impact of any outage or issue in Jito’s block engine. Performance data and adoption metrics beyond the earlier company disclosures have not been publicly provided in the new report, leaving its broader effect on transaction success rates and latency still to be tested.
