Secure your assets
with BVGS
Protect your wallet from hacks, phishing attacks, and private key compromises with your personal, self-custodied Bag
How BVGS works
BVGS adapts OpenZeppelin's ERC-721 NFT and ERC-5192 soulbound standard to provide tokenized security for your self custody wallet.
View documentationSelect assets to bag
Select which crypto assets or NFTs you want to secure within your Bag. BVGS supports Ethereum, ERC-20 tokens, and ERC-721 NFTs, allowing you to protect a diverse range of assets in one place.
Choose your key management type
Choose between BVGS key fraction technology or self custody key management options for your Bag. Our patent-pending key fraction technology trustlessly creates a unique key linked to your Bag, freeing you from managing additional keys.
Mint and secure your assets
Mint your soulbound Bag through our secure bagging process, permanently locking your Bag and your selected assets to your wallet. Your bagged assets cannot be accessed without your Bag's linked key, ensuring your funds stay safe even in the case of a wallet attack or compromise.
BVGS key fraction technology
Explore how BVGS key fraction technology works with this interactive demonstration. See how two separate key fractions can be combined to deterministically generate consistent cryptographic results.
How it works
This sandbox demonstrates the core concept behind BVGS key fraction technology:
- Two separate key fractions are combined to create secure keys
- Neither fraction alone can generate the final keys
- Same input fractions always produce the same result
- BVGS only stores one encrypted fraction - you control the other
