Five Bells, a financial technology startup founded by former executives from NYDIG and Two Sigma, has successfully closed its seed funding round to develop a specialized settlement infrastructure for the Bitcoin network. Led by Ego Death Capital, the investment round also saw participation from Epoch VC, Timechain, and Fulgur Ventures. The project aims to establish the first native Delivery versus Payment (DvP) layer for Bitcoin, specifically designed to address the counterparty risks inherent in large-scale institutional transactions.
Mitigating Institutional Counterparty Risk
The primary objective of Five Bells is to eliminate the "herstatt risk" or settlement risk that occurs when one party fulfills their obligation in a trade before the other. By utilizing a custodial-like locking mechanism on the blockchain, the platform allows participants to pre-lock settlement terms directly on-chain. This system ensures that BTC is only released once there is a verified confirmation of the corresponding fiat wire transfer or stablecoin payment.
- Reduction of operational friction in high-volume OTC trades.
- Elimination of intermediary settlement costs through automation.
- Enhanced security for institutional liquidity providers and hedge funds.
Leveraging Taproot and FROST Technology
Technologically, the Five Bells solution is anchored in the Bitcoin network itself, treating the protocol as a neutral and shared trust layer. The architecture utilizes Taproot—a major Bitcoin upgrade from 2021—alongside FROST (Flexible Round-Optimized Threshold Signatures) contracts. This combination allows for complex multisig arrangements and privacy-preserving smart contracts that remain compatible with Bitcoin's base layer. FROST is a cryptographic protocol that allows a group of participants to share a private key and create signatures without the full key ever being reconstructed on a single device.
The integration of these advanced cryptographic primitives enables the platform to execute automated settlements without requiring third-party escrow agents, which have traditionally been a point of failure or high cost in the digital asset industry.
By bridging the gap between legacy financial rails and decentralized ledgers, Five Bells seeks to modernize the backend of institutional Bitcoin trading. As the demand for regulated and secure settlement environments grows following the approval of various spot Bitcoin ETFs, the development of native DvP layers represents a significant step in the maturation of the digital asset market infrastructure.
