Privy and Jito Ship FullSend: More Reliable Transaction Landing on Solana
Privy has integrated FullSend, the transaction-landing service built with Jito, into its wallet stack. Privy cites 99.999% landing reliability since January and submission in 4 instead of 25 milliseconds, with MEV protection by default.
What happened
FullSend, the transaction-landing service built together with Jito, is now integrated directly into the wallet infrastructure of Privy (part of Stripe). According to the announcement, transactions routed through Privy go through FullSend by default. FullSend sends them directly to current and upcoming Solana leaders over Jito’s low-latency network, with MEV protection built in.
The numbers (per Privy)
- 99.999% landing reliability: Privy cites this figure for the period since January, measured across millions of Solana transactions routed through Privy.
- 4 instead of 25 milliseconds: Via the direct FullSend connection, Privy submits transactions in as little as 4 milliseconds — versus an average of 25 milliseconds for customers connecting independently.
- MEV protection by default: Protection against attacks such as front-running and sandwiching is active out of the box.
Important context: these figures come from Privy’s own announcement and have not been independently verified so far.
Why transaction landing matters
“Landing” describes whether and how quickly a submitted transaction actually makes it into a block. Under heavy network load, transactions can be delayed or dropped entirely — a well-known friction point on Solana that several infrastructure providers compete to solve. How MEV — the reason for the built-in protection — works on Solana is covered in our piece MEV on Solana. On Jito’s role in the network: Jito BAM reaches validator majority.
