Vastbase FAQ

Vastbase is a next generation multisig wallet for digital asset management and onchain businesses, such as: Crypto treasuries (in BTC, ETH, SOL, stablecoins, ERC-20, NFT, …) , RWAs, DAOs and VC funds. It is built on top of Vastlink WaaP.

What can we learn from the biggest crypto hack in history - Safe{Wallet} & Bybit $1.4B hack?

💡 Hopefully MPC could make things better as the private key would never be exposed, and the mentioned security mechanisms can be built on the protocol level to prevent hacks like this.

Decentralized MPC - The Future Infrastructure for Crypto Wallets

Multi-Party Computation, often abbreviated as MPC, is a cryptographic protocol that enables multiple parties to jointly compute a function over their inputs while keeping those inputs private. In simpler terms, it allows different entities to collaborate on computing a result without revealing their individual data.

FAQ

What is the difference between Wallet-as-a-Protocol and Wallet-as-a-Service?

Vastlink is fully open source and decentralized powered by tokenomics.

Can we self‑host Vastlink?
