Previa Launches Fullsend with Gitab Labs to Cut Transaction Delays to 50 Milliseconds

Stripe subsidiary Previa has launched Fullsend, a new tool with Solana infrastructure company Gitab Labs, to expedite transaction confirmations. Fullsend prioritizes transactions sent from Previa wallets to be included in the Solana blockchain at maximum network speed, achieving a 99.999% success rate across millions of transactions since early this year. Previa CTO Asta Lee emphasized the complexity of Solana transactions, noting developers no longer need to manually manage fees, priority settings, or endpoint selection. Fullsend routes signed transactions directly to Solana leaders via low-latency networks, mitigating MEV risks like sandwich attacks and front-running. Gitab Labs CEO Lucas Brueder called Solana's performance hinges on transaction speed and reliability, calling Fullsend an infrastructure solution that applies standard priority fees and inherently protects against MEV extraction.
