Arqit WalletSecure™ Digital asset security for Ethereum
WalletSecure is a security enhancing product for Ethereum designed to prevent unauthorised control of digital assets.
Secure Your Digital AssetsThe Private Key Problem Now
Wallets are controlled by private keys, which means anyone holding these keys can sign transactions on behalf of the legitimate owner
These keys may be breached through traditional hacking means, though security can be enhanced using a multi-sig/MPC wallet
If the keys are compromised, an adversary can sign transactions to send assets to another wallet without the legitimate owner’s consent
WalletSecure Protects Against Exploits
- $53 million stolen from CoinEx in September 2023
- Wintermute lost $160M in 2022
- Atomic wallet had over $100M stolen from users July 2023
- Harmony bridge drained of $100M from compromised multi-sig private keys
- Slope wallet on Solana had $6M stolen from users wallets
- Ronin network had $625M stolen from private-key compromises
- Many individuals have had private keys compromised over the years, some amounting to multi-million dollar thefts
WalletSecure could have prevented these exploits and more. Even if the key is hacked or stolen, the digital asset remains secure.
WalletSecure In Action
Using WalletSecure, a cybercriminal with access to someone else’s private key(s) cannot steal any of the digital assets in the wallet.
For a transaction to be sent, two signature types are required:
- The Ethereum signature from the digital asset owner
- The post-quantum signature from WalletSecure
WalletSecure Design
To authenticate the transaction provenance from the legitimate owner’s device, WalletSecure uses Arqit SKA Platform™. The protocol’s post-quantum signature is only combined with the Ethereum signature if it has originated from the correct source, meaning that if the private key is stolen by a cybercriminal, the digital asset still cannot be moved.
Real-time regulatory compliance can be integrated with WalletSecure, such as KYC AML and blacklisting, preventing non-compliant transactions before they happen.
WalletSecure is EVM-compatible so can be used with existing security solutions such as MPC, as well as any DeFi protocol supporting smart contract wallets.
