PROVABLE SELF-CUSTODY WALLET
The only self-custody wallet that is provably secure
Provable self-custody maintains custody integrity without the need for trust. Your entire custody process is verifiable on-chain, which means nobody can seize, move, or exploit your funds. Levain's wallet is truly non-custodial, just the way it should be.
Absolute control and oversight of your digital assets
True, provable self-custody gives you absolute control and oversight over your crypto assets over their entire lifecycle. No third parties can gain access to manage your digital assets through the custody lifecycle:
Initial generation of private key material that holds the digital asset
Storage of the private key material
Creation of the multi-sig wallet on-chain
Process of transacting with the digital asset
Secure. Transparent. Decentralized. Simple.
Provable self-custody means all aspects of the custody process are verifiable and auditable on-chain, ensuring asset custody is managed securely. Here’s how:
No manipulation by any external party
As random number generation is a core aspect of wallet management and key generation, we do not compromise on it. Your keys are generated client-side on your browser and never server-side, using cryptographically secure pseudorandom number generation (CSPRNG). The generated keys are never transmitted to our servers, meaning your keys and wallets belong solely to you, safeguarded from any external party - this includes Levain.
Transactions are verified on-chain
Built on transparency, transactions and interactions – including approvals by individual key holders – are publicly verifiable on-chain via blockchain explorers.
No single point of failure
Levain is non-custodial and has zero knowledge of your private keys, so we cannot move assets held in self-custody. Creating a Levain wallet gives you keycards with assigned values to help recover your private keys. Only you - and solely you - can recover your private keys.
You have 100% autonomy and control over your private keys, meaning you neither need nor have to trust Levain to access your funds.
Proof is not rocket science
In digital asset management, it is important to adopt a system that is simple to understand and verify. This significantly enhances accuracy, leaving no room for errors.
This is why Levain uses the highest form of on-chain security: multi-signature, which gathers Elliptic Curve Digital Signature Algorithm (ECDSA) signatures to execute transactions.
Multi-sig vs. MPC (TSS)
Multi-sig: Provable self-custody wallet
Multi-sig provides enhanced transparency because the entire transaction is verifiable on-chain. 1 private key generates 1 signature and N and M signatures are needed to sign the transaction - all on-chain.
With multi-sig, your keys remain yours, and are offline.
Verifiable on-chain signatures
Conversely, MPC signature consensus happens off-chain. Off-chain means you cannot verify. MPC shards 1 private key into multiple. Multiple parties must agree and sign to execute the private key. Signatures unite off-chain, but execute on-chain.
With MPC, your keys are online, and you sign according to your platform's instructions.
