BiorVault - One seed phrase. Six chains. Zero custody risk Overview

BiorVault is a decentralized, non-custodial multi-chain crypto wallet that bridges Web2 convenience with Web3 empowerment. Instead of juggling separate apps and scattered seed phrases across chains, users manage Bitcoin, Ethereum, Solana, Polkadot, Cosmos, and DeFiChain from one wallet, one seed phrase, and one security model with a cold storage vault mode for long-term holdings sitting behind an extra gate on the same device.
