EarnPark On-Chain Architecture

EarnPark is moving to a full on-chain protocol layer — EarnPark OnChain Protocol — on which the platform's yield strategies will run. The architectural principle: one underlying — one wrapper — many strategies, with compliance enforced at the system's boundaries and a clean separation between reserve, yield and protocol revenue.

• Boundary AML. Compliance is enforced at mint (ingress) and cash-out (egress), not on every secondary transfer. This preserves the full on-chain utility of the asset while keeping a defensible compliance perimeter.

• Wrapper rail. For each underlying asset the protocol issues a single freely transferable wrapper token (e.g. USDEP for USDT), fully backed by a reserve of that asset. Reserve yield accrues to the protocol as a separate revenue stream — the wrapper remains a transport layer, not a yield-bearing instrument.

• Strategy products. Each strategy is a standalone product with its own share token, wrapped in smart contracts that hard-code the rules of capital movement: approved addresses, exposure limits, cooldowns. Capital cannot move outside the defined perimeter.

Strategy access is opened through non-custodial wallets: the user holds wrapper and strategy share tokens directly and decides whether to stay in the clean wrapper or enter a specific strategy. Contracts are verifiable on-chain; upgrades go through timelock.

Integration of the PARK token into the on-chain layer is the phase that follows protocol launch; specifics will be added in later revisions of this whitepaper.

The full architecture, economic model, risk framework and go-to-market are described in a separate document — EarnPark OnChain Protocol Whitepaper.
