Nexio is organized as a three-layer BTC lending platform. These layers connect institutional lenders, borrower-specific credit facilities, and the custody and control processes that move BTC through the life of each loan.
  1. Client Layer: The institutions that supply or borrow BTC through Nexio.
  2. Operations Layer: The underwriting, facility structuring, servicing, monitoring, and reporting workflows that run the lending business.
  3. Custody Layer: The custody and settlement infrastructure that receives BTC, funds approved borrowers, processes repayments, and keeps balances reconciled.
Together, these layers let lenders allocate BTC to defined borrower opportunities while Nexio manages credit selection, operational controls, and repayment tracking.

​
1. Client Layer

The Client Layer represents the counterparties participating in Nexio’s lending marketplace. This primarily includes:
  • Institutional lenders: Funds, family offices, corporate treasuries, and other BTC holders seeking fixed-term BTC income.
  • Institutional borrowers: Trading firms, market makers, hedge funds, and other approved counterparties seeking BTC financing.
Lenders do not allocate into a general pool. Instead, they choose a specific borrower facility, often referred to in the docs as a Series, based on its borrower profile, term, coupon, strategy, and covenant package. Each facility corresponds to one borrower and one defined set of commercial terms. That gives lenders visibility into who is borrowing the BTC, how long it will be committed, and what repayment obligations apply.

​
2. Operations Layer

The Operations Layer is the core of the platform. It is where Nexio originates, approves, and services each lending facility. This layer includes five main functions:
  • Underwriting and onboarding: Nexio completes KYC/KYB, credit review, compliance checks, and borrower approval before a facility is opened.
  • Facility structuring: Nexio defines the interest rate, facility size, duration, repayment schedule, permitted use of proceeds, and borrower-specific covenants.
  • Lender allocation: BTC deposits are booked to the relevant borrower facility so exposure remains tied to the selected borrower rather than being mixed across unrelated programs.
  • Servicing and monitoring: Nexio tracks utilization, borrower reporting, coupon payments, covenant compliance, and concentration limits throughout the loan term.
  • Legal and reporting workflow: Every facility operates under legal agreements and reporting requirements that define payment obligations, default remedies, and lender protections.
This is also the layer where Nexio applies its credit scoring framework, concentration limits, and covenant monitoring. In practice, lender protection comes from disciplined underwriting, legal structure, ongoing monitoring, and operational controls across the life of the facility.

​
3. Custody Layer

The Custody Layer handles how BTC is received, held, disbursed, and reconciled. Nexio uses approved custody and settlement arrangements designed for institutional lending. The objective is to keep assets segregated, control the movement of BTC, and maintain records that support lender reporting and internal oversight. This layer typically includes:
  • Deposit receipt and booking: Lender BTC is received into the relevant custody arrangement and recorded against the selected borrower facility.
  • Segregated handling of assets: Balances are tracked through borrower-specific account structures and internal controls to reduce commingling risk.
  • Controlled borrower funding: BTC is released only after the facility’s legal, credit, compliance, and operational conditions have been satisfied.
  • Repayment processing and reconciliation: Coupon payments and principal repayments are received, matched to the correct facility, and reflected in Nexio’s reporting.
  • Auditability: BTC movements can be reconciled against custody records, facility records, and lender reporting so stakeholders can verify how each facility is being serviced.
The Custody Layer does not replace credit underwriting, but it provides the operational backbone that makes funding, repayment, and recordkeeping reliable.

How the Layers Work Together

In practice, Nexio’s architecture works as follows:
  1. A lender selects a borrower-specific facility and deposits BTC under the published terms.
  2. Nexio books that BTC to the relevant facility and keeps the exposure associated with that borrower.
  3. Once the borrower’s onboarding is complete, legal documentation is in place, and any ongoing compliance and funding conditions are satisfied, BTC is disbursed to the borrower through approved settlement instructions.
  4. The borrower deploys the BTC within the bounds of the agreed facility and strategy.
  5. Nexio monitors reporting, covenant compliance, facility utilization, and payment performance during the loan term.
  6. Coupon payments and principal repayments flow back through the custody and servicing process, after which lenders can withdraw or recommit BTC according to the facility terms.
The result is a lending architecture built around identified borrowers, fixed commercial terms, controlled BTC movement, and ongoing servicing rather than a generalized tokenized credit pool.
