VerifiedX Brings Native Bitcoin Redemption and FROST Privacy to Base DeFi with Fireblocks Integration
The VerifiedX foundation has announced the launch of vBTC.b on Base with support for Fireblocks, aimed at bringing Bitcoin’s digital gold qualities and world-class brand recognition to Defi and the Institutional self-custody markets.
According to a press release shared with Bitcoin Magazine, VerifiedX is the first “Non-Synthetic Bitcoin Asset” with built-in native bitcoin redemption, compatible with Base, Coinbase’s increasingly popular EVM blockchain and Defi platform. “vBTC is now live as a canonical asset on Base under the ticker vBTC.b and is officially listed inside the Fireblocks platform with self-custody enabled.”
While the integration with Base makes vBTC available to the public. The integration with Fireblocks unlocks institutional interest, as Fireblocks is a leading institutional digital asset custodian and a powerful brand in the Western market.
According to DefiLlama, the Defi market today holds over 80 billion in value. While Bitcoin remains the king of the crypto markets, its representation in Defi remains small; only 5 billion worth of value is held in Bitcoin across the broader crypto-defi ecosystem, while Ethereum holds over 43 billion of the same.
VerifiedX believes there is strong demand for Bitcoin inside Defi, with institutions increasingly interested in self-custody solutions that can satisfy their needs for regulatory compliance as well as privacy from onchain analysis and front running. VerifiedX has been designed around these expectations, while innovating beyond traditional bridges, synthetic bitcoin wrappers and trusted federations.
Their novel approach leverages a large open network of FROST multiparty computation (MCP) nodes that arguably set a new standard for cross-chain technologies. The VerifiedX tech stack has received “an institutional full-stack audit via Halborn.”
Bitcoiners can expect enhanced integration with Defi rails from vBTC, with new utility such as “programmable settlement, collateralized borrowing, yield strategies, and AI-agent commerce” among other potential features, while leveraging a far more decentralized and self-custody oriented cross-chain technology than has been available to date. The VerifiedX chain also has zero-knowledge proof technology built in natively, providing a privacy benefit to its users as they move BTC in and out of the system, shielding them from onchain analytics.
FROST Multi-Party Computation and Self-Custody
The VerifiedX network leverages breakthroughs in cryptography built around Bitcoin’s taproot upgrade. Each VerifiedX validator runs a FROST multi-party computation (MCP) server, a sophisticated and scalable form of Shamir secret sharing developed independently of VerifiedX.
FROST, which stands for “Flexible Round-Optimized Schnorr Threshold Signatures,” unlocks a technology simil
