Levain Wallet's Security Model
Levain believes security is paramount when it comes to managing digital assets on the blockchain, and it is at the core of everything we do. In this article, we will delve into the heart of our Levain Wallet and explore how we design self-custody wallets that ensures the highest level of security for your digital assets.

Wallet, providing signing capabilities required as part of making transactions from your Levain Wallet. Signing comes in the form of a cryptographic signature that is viewable on-chain using public block explorers, which is generated using the
