Prism

What we built

Prism is a DeFi aggregator for OPN Chain. It puts swapping, earning yield, staking, and portfolio tracking behind one interface, so you can move through the OPN ecosystem's real deployed apps in a single click without leaving the page. If you have used Jumper or 1inch, it is that idea scoped to OPN.

For a first-time user: it is one app that lets you trade tokens and put them to work earning yield, instead of hunting down a separate site for each.

For a developer: it is a router contract plus a set of thin adapters. The frontend never talks to target protocols directly, and every action is a real on-chain transaction routed through Prism.

Why it matters

Most of the OPN ecosystem today is single-function: one vault here, one swap there, each with its own site. Prism is the layer on top that ties them together. The goal is not another isolated app. It is a front door that sends users into the apps that already exist, and a clean way for new apps to plug in.

How it works

You only ever interact with one contract, OPNRouter. It pulls your token, takes a small configurable fee on routed volume, and forwards the action to a whitelisted adapter that knows how to talk to a specific protocol. It is reentrancy-guarded and takes no custody beyond the single transaction.

Each integration is one small adapter:

• RoutedSwapAdapter: swaps through Uniswap-V2-style AMMs, with the target router passed in calldata, so one adapter can route through any venue.
• VaultDepositAdapter: deposits into yield vaults.
• ZapAdapter: swap then deposit in a single call.
• StakeAdapter with EscrowFactory: stakes into a per-user escrow contract.

New apps join by adding an adapter. The core router never changes. The same router handles swaps, earn, stake, and zaps, so the aggregator pattern is not tied to one action type.

People holding only the native gas token are covered too. routeNative wraps native OPN into WOPN inside the router, so you can swap or zap straight from OPN with no manual wrapping step.

What is live

Deployed and source-verified on OPN testnet (chain 984):

• Swaps route through the live OPNSwap V2 router over the real WOPN/mUSDT pool.
• Earn deposits go through VaultDepositAdapter into the PrismVault set.
• Stake routes through StakeAdapter into a per-user escrow.
• A native-OPN zap (OPN, then WOPN, then asset, then vault) runs in one transaction.

The frontend is Next.js with wagmi and viem: Swap, Earn, Stake, Portfolio, and Missions pages, multi-wallet connect, and a testnet faucet for mock tokens. Live stats (route count and routed volume) are read straight from on-chain Routed events.
