Nexio combines institutional credit underwriting with BTC-denominated lending. The concepts below explain the core building blocks of the current model.

​
1. Series

A series is a defined BTC lending arrangement between Nexio, approved lenders, and a specific institutional borrower. Each series has its own commercial terms and risk profile. Rather than contributing to an open pool, lenders are taking exposure to a specific borrower opportunity with defined parameters. Those parameters typically include:
  • A defined strategy (e.g., CME basis, delta-neutral, market-making)
  • A fixed interest rate and duration
  • Named borrowers that have completed Nexio’s KYC/KYB onboarding
  • A repayment schedule
  • Series-specific covenants and reporting requirements
This structure helps lenders evaluate borrower risk on a case-by-case basis rather than relying on a pooled, one-size-fits-all product.

​
2. Borrower Vaults

Nexio uses borrower vaults as segregated operational buckets for tracking lender allocations, borrower funding, and repayment activity. In the current model, a borrower vault is not a DeFi primitive or tokenized structure. It is a controlled Series-level construct used to separate exposure, maintain clean records, and support reporting. That separation matters because it helps Nexio:
  • Track each lender’s exposure to a specific borrower
  • Keep series activity distinct from other borrower programs
  • Reconcile deposits, disbursements, coupon payments, and repayments
  • Reduce the risk of commingling or rehypothecation
If a lender allocates BTC to a borrower vault, that BTC is associated with that borrower series and its agreed terms rather than being converted into a protocol token or pooled across unrelated activities.

​
3. Custody and Settlement

BTC is held and moved through centralized custody and settlement workflows designed for institutional use. Nexio works with approved custodians and controlled operational processes to support:
  • Asset segregation
  • Transaction approval controls
  • Borrower funding
  • Repayment processing
  • Ongoing reconciliation and reporting
This is an important distinction from older crypto lending models: Nexio does not rely on tokenized deposit receipts, decentralized custody, or smart-contract-native fund flows to operate the product.

​
4. Credit Underwriting and Covenants

Because Nexio supports undercollateralized and uncollateralized lending, underwriting is central to the platform. Before a borrower receives BTC financing, Nexio reviews factors such as:
  • Business quality and operating history
  • Financial condition and liquidity
  • Risk management processes
  • Compliance and governance standards
  • Strategy profile and use of proceeds
Once a series is approved, Nexio applies covenants and reporting requirements that may include borrowing limits, payment schedules, information rights, and other controls designed to protect lenders. In other words, lender protection comes primarily from underwriting, legal structure, monitoring, and disciplined operations rather than automatic overcollateralized protocol mechanics. Each Nexio series is backed by legal documentation that defines the rights and obligations of the parties involved. These documents typically include:
  • The master lending framework with the borrower
  • Series-specific term sheets or credit terms
  • Covenant and reporting obligations
  • Default, enforcement, and recovery provisions
Where applicable, additional collateral or security documents may also exist, but the platform is not defined by overcollateralized lending. This legal layer is what makes the product institutional: borrowers are identified counterparties with binding contractual repayment obligations.

​
How It All Fits Together

Together, these concepts form Nexio’s operating model:
  • Series define the economic terms of each loan program.
  • Borrower vaults keep allocations and reporting tied to a specific series.
  • Centralized custody and settlement control how BTC is held, funded, and repaid.
  • Underwriting and covenants govern who can borrow and on what terms.
  • Legal agreements anchor each lending relationship in enforceable obligations.
The result is a BTC-denominated institutional lending platform built around identified counterparties, clear commercial terms, trusted custody, and lender-visible payment flows.
