WhitePaper Executive Summary

EarnPark On-Chain Protocol is infrastructure for issuing freely transferable wrapper tokens for individual underlying assets and launching multiple yield products on top of each such wrapper.

The system is divided into two layers. The first layer is the wrapper rail. For each underlying asset, a single wrapper token is created. For example, for the USDT series this may be USDEP, for the WETH series — ETHEP, for the WBNB series — BNBEP. The user deposits the underlying asset through an AML-gated entry, receives the wrapper, and can freely hold, transfer, or use it within the ecosystem.

The second layer is strategy products. On top of a single wrapper, multiple strategies can coexist: for example, USDEPStrategy1, USDEPStrategy2, and USDEPStrategyPrime. The user decides whether to stay in the base wrapper layer or convert the wrapper into one of the yield products.

Why this architecture matters: it simultaneously preserves a single clean base wrapper per asset, multiple strategies on top of the same rail, and a clean separation between protocol revenue and user yield.

2. The Problem the Protocol Solves

In the digital asset market, it is difficult to satisfy several requirements at once. Users need an asset that can be freely moved and used as a base unit of liquidity. At the same time, compliance control at the level of boundary operations is required at entry and exit. Finally, investors need access not to a single product, but to a lineup of strategies differentiated by risk, duration, and target yield.

Typical DeFi designs often break down at this intersection. If a token is too tightly controlled, it loses utility. If it is completely unrestricted, the compliance framework becomes weak. If the base wrapper and yield are mixed into a single product, it becomes difficult to separate the reserve, user profit, and protocol revenue.

EarnPark On-Chain Protocol proposes an architecture in which these tasks are separated into distinct layers: compliance lives at the system's boundaries, the freely transferable wrapper resides in the base layer, and user yield sits in separate strategy products.

3. EarnPark On-Chain Protocol Org

EarnPark On-Chain Protocol is organized around the concept of a Series. Each Series corresponds to one underlying asset and includes a single wrapper token, a single reserve, a single gateway, a single AML policy for mint/redeem at the boundaries, and a single reserve adapter for productive storage.

Level	Components	Role
Series	Wrapper token, reserve, gateway, AML policy, reserve adapter	Base clean asset rail for one underlying
Strategy	Separate pool, strategy share token, yield parameters, fees, cooldown, risk limits	Yield product on top of a single Series

Taking the USDT series as an example: inside it exists a single USDEP wrapper, and on top of it multiple strategies can operate. This means:

• one asset — one wrapper;

• one wrapper — many strategies;

• each strategy — a separate product with its own economics.

Series Example

Series	Wrapper	Strategies	Exit
USDT Series	USDEP	USDEPStrategy1, USDEPStrategy2, USDEPStrategyPrime	Redemption back into USDT via boundary payout path
WETH Series	ETHEP	ETHEPStrategy1, ETHEPStrategyMarketNeutral	Redemption back into WETH via boundary payout path
