Stripe-owned wallet provider Privy has partnered with Solana infrastructure firm Jito Labs on FullSend, a transaction inclusion tool that routes every Privy wallet transaction directly to the current Solana block-building leader, bypassing public RPC nodes.
"Transaction landing on Solana became more complicated than it ever needed to be — tips, priority fees, picking the right endpoint. We wanted to make that entire decision disappear for developers," Privy CTO Asta Li said.
FullSend has been running in production inside Privy wallets since January, achieving 99.999% landing reliability across millions of transactions, according to the companies. The tool cuts inclusion latency to 50 milliseconds, compared with at least 200 milliseconds for traditional Solana wallets that send transaction data to a public or hosted RPC node. Solana rotates block-building leaders roughly every 400 milliseconds per slot, following a predetermined schedule based on stake.
The system also bypasses Maximal Extractable Value risks, including bots front-running, sandwiching, or censoring transactions. Jito Labs CEO Lucas Bruder said the tool is designed for fintechs, market makers, and other institutional Solana users who need speed and certainty when transacting on a blockchain. "The best applications on Solana win or lose on how fast and reliably their transactions land — that's the whole game," Bruder said. "FullSend is our answer at the infrastructure layer: straight to the leader, standard priority fees, MEV protection by default."
Privy, which Stripe acquired in 2025 following its $1.1 billion purchase of stablecoin infrastructure firm Bridge, counts fintechs including Klarna, Ramp, and Deel as users, as well as the perpetuals exchange Hyperliquid. The wallet provider claims 140 million accounts processing billions of dollars in monthly volume. Stripe is also co-developing Tempo, a stablecoin-focused Layer 1 blockchain.
Earlier this year, Privy partnered with Alchemy on an institutional onboarding solution for onchain finance. The FullSend launch deepens the integration between traditional payments infrastructure and Solana DeFi, potentially attracting more institutional projects to the ecosystem.
