If you’ve ever submitted a Solana transaction and watched it disappear into the void, you’re not alone. A new integration between wallet infrastructure provider Privy and MEV specialist Jito is designed to make that experience a relic of the past.
The two companies have co-developed FullSend, a tool that automatically routes every transaction signed in a Privy wallet directly to whichever validator is currently building the next Solana block.
How FullSend actually works
Under normal circumstances, Solana transactions travel through RPC (Remote Procedure Call) nodes before reaching a block producer. RPC routing introduces latency, and during periods of high network congestion, it can lead to dropped or delayed transactions. FullSend sidesteps this entirely by leveraging Jito’s block engine to send transactions straight to the active block-building leader.
The integration runs under the hood of Privy’s wallet infrastructure, meaning developers building on Privy don’t need to implement custom routing logic. Every transaction signed through a Privy wallet, whether it’s an externally-owned account or an embedded wallet, gets the FullSend treatment automatically.
Privy has positioned itself as a provider of embedded wallet and authentication solutions across the Solana ecosystem, targeting applications that want to abstract away the complexity of wallet management for end users.
Jito’s quiet dominance of Solana infrastructure
Jito operates Solana’s primary MEV block engine and leader auction systems. Its modified validator client runs on the majority of the network’s stake, making it the backbone of how transactions actually get prioritized and included on the chain.
MEV, or Maximum Extractable Value, refers to the profit that validators or searchers can extract by reordering, inserting, or censoring transactions within a block.
For Privy, partnering with Jito extends its strategy to build wallet infrastructure. The company has previously worked with Helius, another prominent Solana infrastructure provider.
What this means for Solana users and investors
FullSend addresses transaction reliability at the application layer rather than the protocol layer. Protocol upgrades require network-wide consensus and take time. Application-layer improvements can be deployed immediately and benefit users without waiting for validator upgrades.
For developers building consumer-facing applications on Solana, FullSend removes a routing optimization problem from their implementation requirements. Every transaction signed through a Privy wallet, across both externally-owned accounts and embedded wallets, is routed automatically.
There’s also a centralization question worth flagging. Jito’s client already runs on a majority of Solana’s stake, and deeper integration with wallet providers like Privy concentrates more of the transaction pipeline through Jito’s infrastructure. If Jito’s block engine experiences issues, the blast radius is significant.
Performance data and adoption metrics for FullSend haven’t been publicly disclosed yet, so the actual impact on transaction success rates and latency remains to be seen.
