Verifiable Bitcoin Accounts for Institutional Bitcoin. Your Custody, Your Terms.

New York, United States of America, April 23rd, 2026, Chainwire

Threshold Network today announced Verifiable Bitcoin Accounts (VBA), a new framework for institutional Bitcoin deployment built on the same signer infrastructure that has operated with Bitcoin for six years, processed over $5 billion in cumulative volume, and sustained zero losses.

Verifiable Bitcoin Accounts are a Bitcoin Script and PSBT-based account framework for institutional Bitcoin deployment. They define preauthorized spending paths, signer combinations, timelocks, and recovery routes at account setup, allowing allocators to use Bitcoin-backed onchain strategies while preserving segregated custody workflows and verifiable settlement paths.

Your Bitcoin, Your Custody

BTC remains with the holder's existing custody arrangement. VBA is compatible with Qualified Custodians such as Anchorage and Fireblocks Trust, MPC-based custody networks, and self-custody setups. No title transfer outside of their existing custody. Capital is held in a segregated account, not pooled, and is identifiable at all times. The custody relationship that the allocator already maintains governs every deployed position.

Built for Bitcoin Finance

Institutional Bitcoin lending is accelerating toward a projected $90B by end-of-2026¹, driven by stablecoin growth that reached $308B in early 2026 and is on track to exceed $1T². While major platforms are building proprietary lending stacks to capture the demand, Verifiable Bitcoin Accounts turn any existing custody - Qualified Custodian, MPC network, or self-custody - into institutional-grade lending infrastructure.

Onchain Bitcoin lending and yield markets depend on collateral that resolves reliably across liquidation, maturity, and redemption. Verifiable Bitcoin Accounts are built for that operational reality, with every settlement route agreed at setup and enforced in Bitcoin Script.

For allocators deploying Bitcoin into onchain lending at scale, this is the guarantee that makes the product usable.

Bitcoin-Level Integration Path

The foundation of every Verifiable Bitcoin Account is the Partially Signed Bitcoin Transaction (PSBT), supported by the following features:

• Consensus-enforced spending. Spending conditions, recovery paths, and timelocks are written in Bitcoin Script and enforced by the same consensus mechanism that secures the Bitcoin network. Every permissible outcome is pre-defined. Every state is verifiable onchain by any full node.
• Multi-party controls. No single entity holds unilateral authority over deployed capital during the term of the agreement. Not the custodian, not Threshold, not the depositor. Every movement requires the predefined combination of parties specified for that position.
• Predefined recovery. If the signer network is unavailable, the depositor recovers the BTC themselves after a defined timelock. No counterparty cooperation is required. The Bitcoin UTXO is the system of record.
• Whitelisted deployment. Capital deploys only into risk-assessed, pre-approved onchain lending and yield markets such as Aave, Morpho, Curve, and Yield Basis. Every movement is constrained, auditable, and aligned with institutional compliance requirements.

The signer infrastructure, Threshold Network, the protocol behind Verifiable Bitcoin Accounts, has operated with Bitcoin for six years, with over $5 billion in cumulative volume and zero losses. Verifiable Bitcoin Accounts is the extension of this proven, existing infrastructure.

Verified, Not Just Trusted

Institutional adoption of Bitcoin in onchain markets does not scale on assurance alone. It scales on independent verification.

"Institutions don't need additional layers of trust; they need systems where outcomes are defined, enforceable, and verifiable from the outset. By removing reliance on counterparties, we align Bitcoin onchain with the standards institutional capital actually requires." — MacLane Wilkison, Co-Founder of Threshold Network

Verifiable Bitcoin Accounts (VBA) establish a new standard for institutional Bitcoin deployment: every component of the architecture can be verified before a single satoshi is committed.

Verifiable Bitcoin Accounts are available to qualified institutional participants. To discuss integration and explore deployment into approved onchain venues, users can contact the team via: https://threshold.network/contact
