Welcome to River

River is institutional asset-backed finance (ABF) infrastructure and risk management for the stablecoin economy.

It matches deep on-chain liquidity with real-economy credit portfolios through native risk and duration transformation, providing a resilient, independent funding leg for tier-one fintech originators and an institutional-grade path to non-crypto-correlated yield for stablecoin allocators.

River implements traditional credit machinery on-chain, programmatically enforcing accounting, priority of payments, pricing, covenants, exits, and loss allocation. Execution maintains institutional structured finance rigor while settling directly on public infrastructure.

The Core Credit Disconnect

Contemporary capital allocation remains constrained by severe structural inefficiencies across both on-chain and legacy markets:

• The Circularity Problem: Capital within stablecoin and DeFi ecosystems is heavily concentrated in crypto-endogenous exposure. Reaching real-world credit historically required accepting opaque credit processes and extreme headline risk. Furthermore, asset allocators face a fundamental duration mismatch: their liability profiles demand short-term liquidity, while institutional credit portfolios require multi-year commitments.
• The Concentration Problem: Premium fintech originators running high-cadence asset programs face acute funding concentration, relying exclusively on legacy commercial banks and specialized private credit funds. Operating on legacy settlement cycles results in a T+3 or weekly draw cadence, creating an expensive working-capital drag between asset origination and warehouse funding.

River resolves these mismatches by acting as a programmatic layer that executes duration transformation, continuous validation, and instant settlement.

Protocol Capabilities

Composable Seniority Tranching. Each credit facility supports multi-tiered capital stacks, from senior to junior tranches. Programmatic structures protect senior allocators via embedded credit enhancements, including over-collateralization, junior-first loss absorption, excess spread, and reserve accounts.

Optimized Cash Yield. Class tokens behave like native credit instruments. Principal balances are tracked separately from interest liabilities, and interest is distributed as a cash coupon. Allocators requiring automated compounding can utilize the integrated ERC-4626 infrastructure.

Programmatic Priority of Payments. Deposits, allocations, exits, losses, and recoveries are governed entirely by immutable smart contracts. On-chain waterfalls systematically route performance revenues senior-first and absorb underlying impairment junior-first.

Continuous Asset Monitoring. River interfaces with originator and servicer data through automated validation stacks. The system evaluates asset-eligibility metrics, portfolio performance, concentration limits, and stress cases. The resulting marks and covenants are verified on-chain via signed cryptographic reports and automated settlement checks.

Documentation Map

The technical documentation outlines the system from macro operational theory to contract-level implementation:

1. River for Lenders details the interface, transaction lifecycles, and allocator actions.
2. Risks provides an explicit breakdown of systemic risk vectors and the cryptographic and structural controls engineered to mitigate them.
3. Integrate isolates the programmatic token surfaces and external integration matrices.
4. Protocol Architecture and Accounting detail the immutable contract layer and invariant tracking systems.

Core contracts, test vectors, cryptographic audits, and documentation schemas are maintained within the river-contracts repository.
