Stripe-owned wallet infrastructure provider Privy and Jito Labs have co-developed FullSend, a Solana transaction inclusion tool that routes every signed transaction in a Privy wallet directly to the current block-building leader. The tool has been running inside Privy wallets since January and has hit 99.999% landing reliability across millions of transactions.
Why it matters
Privy sits underneath a large share of consumer-facing crypto wallets, including ones built on top of Stripe's own stablecoin and on-ramp products. Plugging Jito's block-builder awareness directly into that flow means MEV-aware routing is no longer something power users toggle on; it is the default. For builders, the implication is that transaction landing is becoming a wallet-level feature rather than something each application has to engineer on its own.
Market impact
The 99.999% landing rate across millions of attempts is the headline number for anyone who has watched Solana transactions fail during congested blocks. The partnership also tightens the link between Jito's block-building layer and the wallets that feed transactions into it, a useful precedent as more MEV infrastructure gets bundled with mainstream wallets.

Privy says FullSend has been running in Privy wallets since January and has achieved 99.999% landing reliability across millions of transactions.
-
Why does routing to the block leader matter?
Sending transactions directly to the current block-building leader reduces the chance of being dropped during congested blocks and is a common technique in MEV-aware infrastructure, where block builders order transactions for landing guarantees.
