Stripe subsidiary Privy partnered with Solana infrastructure firm Jito Labs on FullSend, a transaction certainty tool that ensures Privy wallet transactions are included in Solana blocks as fast as the network allows. Running in production since the beginning of the year, FullSend has achieved 99.999% landing reliability across millions of transactions since January. The tool simplifies Solana transaction complexity around tips, priority fees, and endpoint selection.
FullSend Routes Transactions Directly to Solana Leaders
FullSend automatically routes every transaction signed in a Privy wallet directly to the current and upcoming Solana leaders through Jito's low-latency network. Solana rotates block building leaders roughly every 400 milliseconds per slot, following a predetermined schedule based on stake. The system bypasses Maximal Extractable Value (MEV) risks, including bots front-running, sandwiching, or censoring transactions. Privy CTO Asta Li stated that transaction landing on Solana became more complicated than it ever needed to be, and the team wanted to make the entire decision disappear for developers.
System Achieves 50-Millisecond Inclusion Latency
FullSend cuts Privy's inclusion latency for transactions to 50 milliseconds, putting transactions in front of leaders before the competition. Traditionally, Solana wallets send transaction information to a public or hosted RPC node, which then broadcasts it to the network — a process that takes at least 200 ms. Jito Labs CEO Lucas Bruder stated that the best applications on Solana win or lose on how fast and reliably their transactions land, and FullSend is the answer at the infrastructure layer with straight-to-the-leader routing, standard priority fees, and MEV protection by default.
Privy Serves Fintechs and Institutional Solana Users
The solution is geared toward fintechs, market makers, and other institutional Solana users who need speed and certainty when transacting on a blockchain. Privy counts fintechs like Klarna, Ramp, and Deel as users, as well as Hyperliquid, and claims 140 million accounts that process billions of dollars in monthly volume. Earlier this year, Privy partnered with Alchemy on an institutional onboarding solution.
Stripe Acquired Privy Following Bridge Purchase
Stripe acquired Privy in 2025 following its $1.1 billion acquisition of Bridge. Stripe is also co-developing the stablecoin-focused Layer 1 blockchain Tempo.
