Usury Protocol

A DeFi Primitive for Expected Cashflows

The Primitive consist of two components:

  • 💰 ECVault: Where the payer deposits funds. It tracks defaults & solvency
  • 💸 ECToken (ERC-1155): Represents entitlement to claim future payments from the vault.

Yield is not guaranteed, the primitive carry default risk — and that's the point.

Solvent vaults represnet creditworthyness. 🏦
Risky EC Tokens can be bought at great discounts. 🤑

Risk of Default is the Feature

Because default exists, both sides are incentivized to operate on-chain to minimize trust.

(the economy of the future is on-chain)

👇

Payers want to be trusted

  • If a payer's vault has defaults, their EC tokens become worthless
  • Nobody will buy tokens from unreliable vaults
  • Payers trustworthiness is now a valuable asset.
  • Payers with predictable future cashflow can access present liquidity to increase future returns

Investors need to assess risk

  • High risk = high discount = high potential return
  • Low risk = low discount = safer bet
  • On-chain data is verifiable and trustless

Both actors incentives converge:

Investors value reputation,
Payers benefit from it.

  • Credit scores — on-chain
  • Default registries — on-chain
  • Funding history — on-chain

Makes them verifiable & composable.

Market Fit

Any recurring and predictable payment:

  • Employees seeking salary advances
  • Landlords tokenizing rental income
  • SaaS companies with subscription revenues
  • B2B businesses with invoices/receivables
  • Shareholders with dividend streams
  • Consumers with installment payments

Each market uses the same primitive — just different ECVault implementations.

Crypto Landscape

  • Pendle — Yield trading with guaranteed returns (aTokens, stETH). No default risk.
  • Aave & Morpho — Overcollateralized lending protocols. No default risk for lenders (liquidations protect capital).
  • Goldfinch — Undercollateralized lending for real-world credit. Permissioned borrowers, governance-driven.
  • Maple Finance — Undercollateralized lending with credit delegation. Governance-heavy, permissioned pools.
  • 3Jane — Money market for expected cashflows. Similar concept but aggregated liquidity pool reduces transparency and market efficiency for risk pricing.
  • Levenue-Loom — Revenue-based financing (whitepaper). Similar concept but focused on business revenue streams and a different implementation.

Usury Protocol is permissionless, composable and enables transparent risk pricing.

Our hackathon demo:

Usury Pay & Usury Market

Usury Pay:
A Payroll dApp that gives you the benefit of usury

Provide instant liquidity to employees buying their EC Tokens (unlike other platforms)

Bought EC Tokens accrue value over time making the business profitable

Selling tokens to investors is also profitable: Keeps the app treasury with liquidity and mitigates risk

Usury Market:
A Marketplace that makes usury accessible for everyone

Market signals how interest-rate should adjust

Supply and demand discover real risk pricing

P2P trading offers transparency and better offers
