Following is Press Release
The upgrade brings FROST from research into production infrastructure, enabling multisignature security for Bitcoin transactions at an institutional scale.
Solv Protocol, the Bitcoin asset manager overseeing over $1bn in assets, today announced a major architecture upgrade for SolvBTC, transitioning its Bitcoin mainnet execution layer to FROST, a threshold signature scheme pioneered by the Zcash community that enables institutional-grade multisignature security without requiring any changes to the Bitcoin network itself.
The upgrade evolves SolvBTC’s Bitcoin execution model from Solv’s Staking Abstraction Layer (SAL), launched to standardise Bitcoin staking and yield integrations across ecosystems, into a FROST Network–powered custody and signing architecture designed for stronger operational guarantees as SolvBTC scales.
First introduced in 2020 as a research proposal on the public cryptography ePrint network, FROST had long been recognised for its security and efficiency. Solv’s upgrade marks a major step in bringing this threshold signing model into production on Bitcoin infrastructure.
Under the updated SolvBTC architecture, Solv introduces a FROST-based threshold signing network alongside Vault Pool, Indexer, Auditors, and governed smart-contract controls, providing distributed key management, scalable transaction execution, and auditable workflows to support BTC issuance and redemption at greater throughput and with stronger oversight.
As SolvBTC scales, the largest and most utilized Bitcoin asset on BNB chain is seeing up to 90% utilization rate on ListaDAO, the challenge is no longer limited to integrating staking opportunities across chains, but ensuring Bitcoin mainnet execution remains resilient, governable, and auditable, from address generation and signing coordination through to transaction authorisation and change-control boundaries.
Solv’s move to a FROST-based signing network strengthens this foundation by distributing approval across multiple independent parties, reducing single-point reliance while preserving standard Bitcoin signatures on-chain. Paired with auditable checks and scoped governance, the upgrade introduces clearer accountability and approval processes aligned with the operational standards institutions expect from traditional financial systems.
“Institutions evaluate operational risk and change-control risk,” said Ryan Chow, CEO and co-founder of Solv Protocol. “FROST improves execution privacy, but what really matters to institutions is governance that is analogous to the traditional finance systems. This includes separation of duties, policy-based approvals, audit trails, and time-delayed upgrades. That’s what makes it favoured by a risk committee.”
“For 5 years, Solv always had a strong focus on cryptographic innovation. Our recent research improves the FROST2 algorithm and elevates its security level to TS-SUF-4, the highest security classification,” said Will Wang, CTO and co-founder of Solv Protocol. “We’re expecting this advancement to significantly accelerate the adoption of FROST2 across the Bitcoin ecosystem, enabling the industry to build more efficient and more secure multisignature networks.”
With a more predictable and scalable Bitcoin execution layer, SolvBTC becomes easier for institutional venues and DeFi protocols to integrate, supporting cleaner composability and more reliable mint and redeem flows as Bitcoin finance continues to mature.
By implementing FROST as part of live Bitcoin infrastructure, SolvBTC sets a new baseline for how Bitcoin execution can be secured and governed at scale. The upgrade reflects Solv’s commitment to building an institution-grade operating model that prioritises resilience, clear accountability, and auditable assurance, supporting broader participation in the digital asset space.
