VerifiedX this week launched vBTC.b on Base, a non-synthetic Bitcoin asset that gives users native BTC redemption — meaning holders can actually withdraw Bitcoin, not just trade a pegged token. The rollout targets a glaring imbalance in decentralized finance: DeFiLlama data shows $80 billion in total value locked, but Bitcoin accounts for just $5 billion, while Ethereum holds $43 billion. VerifiedX is betting direct redemption and institutional custody will pull more Bitcoin into DeFi.
How vBTC.b works
The asset isn't your typical wrapped Bitcoin. VerifiedX uses FROST multiparty computation (MPC) and zero-knowledge proofs to handle cross-chain transactions. The system leaves no on-chain footprint during BTC transfers, and the whole tech stack just passed a full-stack institutional audit by Halborn. Fireblocks integration means institutions can self-custody vBTC.b, which should ease compliance concerns for big players.
The Bitcoin gap in DeFi
The numbers tell the story. Bitcoin's $5 billion slice of DeFi is tiny next to Ethereum's $43 billion. That's partly because moving BTC into protocols has historically meant trusting a centralized bridge or accepting a synthetic version you can't redeem for real Bitcoin. VerifiedX is trying to solve the redemption side. If it works, more BTC could flow into lending, trading, and yield protocols on Base and beyond.
Validator requirements and risks
Validators on the VerifiedX network need to stake 5,000 VFX tokens and complete on-chain transactions to participate. The system uses dynamic shard management for threshold signatures. But there's a catch: vBTC doesn't offer true on-chain self-custody. If the entire FROST network goes inactive or fails, users can't unilaterally redeem their Bitcoin. That's a real risk, and one VerifiedX hasn't fully solved. Whether the market accepts that trade-off remains the open question — but for now, the team is pushing ahead, betting that Bitcoin holders want a bridge that doesn't cut them off from the underlying asset.
