Protocol architecture

Four systems.
One credit primitive.

01

Collateral Vault

Deposit memecoins, tokenized stocks, SPL tokens or LP positions into a non-custodial vault. Your assets stay on-chain, your exposure stays intact — they just start working as collateral.

02

Loan Engine

Borrow SOL against your locked collateral in seconds. Dynamic LTVs, transparent interest, and instant settlement — no intermediaries, no approvals, no selling your bags.

03

Risk Layer

Real-time oracle pricing, per-asset risk parameters and health-factor monitoring keep every position solvent. The protocol prices volatility so lenders stay protected.

AB
04

Automated Liquidation

If a health factor drops below threshold, on-chain liquidation flows unwind positions automatically — protecting the lending pool while giving borrowers fair, predictable rules.

How it works

Lock. Borrow. Repay.
Keep your upside.

On-chain credit

Your wallet history
is your reputation.

Eopay turns on-chain activity into a transparent, portable credit score. The more you borrow and repay responsibly, the better your terms — no banks, no paperwork, just provable behavior.

Repayment history35%

On-time repayments are the strongest signal of creditworthiness.

Borrowing volume20%

Total value borrowed and settled over the wallet's lifetime.

Loan activity20%

Frequency and consistency of healthy loan positions.

Wallet age15%

Older, active wallets signal a longer on-chain track record.

Collateral diversity10%

A spread of collateral types lowers concentration risk.

Markets

Your bags are
collateral.

From the hottest memecoins to tokenized stocks and blue-chip SPL tokens — Eopay accepts the Solana assets you already hold. Each market has its own oracle feed and risk-adjusted LTV, so liquidity is always priced fairly.

Risk layer

Solvency is
non-negotiable.

Every loan is overcollateralized, continuously priced, and protected by automated liquidation. Borrowers get liquidity, lenders get safety — enforced by code, not promises.

OtterSecNeodymeSec3ImmunefiOpen Source

Non-custodial vaults

Collateral is held by on-chain programs, never a company. Your keys, your assets, your control.

Real-time oracle pricing

Pyth and Switchboard feeds price every market continuously to keep health factors accurate.

Isolated risk parameters

Per-asset LTV, liquidation thresholds and caps stop volatile collateral from contaminating the pool.

Audited & open source

Programs are independently audited and fully verifiable on-chain. Trust the code, not the team.
