Integrate Ledger Connect


Blocknative is excited to partner with Ledger to help make transacting on web3 easier and safer through the integration of real-time transaction simulations with Blocknative Transaction Preview to simulate transactions pre-flight and calculate the likely outcome of these transactions.

Blocknative's real-time transaction simulations do more than just identify balance changes; they can also be used to identify key risks (like scammers looking to drain your wallet) before your users sign a transaction.

"After first building our own infrastructure, we appreciate that mempool management is a difficult, expensive problem to solve at scale. That's why we partner with Blocknative to power the transaction notifications in our next-generation wallet."
