The system
Exchange
The exchange is an AMM built as a port of Uniswap V3 Core, extended with a typed plugin system. Three pool types — concentrated liquidity, constant product, and amplified stable — answer one shared interface, and every pool ships with the default plugin: dynamic fees, on-chain limit orders, a TWAP oracle, a security module, and a farming proxy. Trading fees are split between liquidity providers and the protocol. The protocol share is what will feed the Earn layer.Start from the Exchange overview.
Earn (coming soon)
The staking layer: stake the platform token, earn protocol revenue in the assets it was earned in, vote on where liquidity incentives go. Documented in Earn as it ships.Bridge
USDC moves in and out of Arc through Circle’s CCTP v2: burned on the source chain, minted on the destination against an attestation signed by Circle. Nothing is wrapped and no third-party validator set is trusted — what arrives is canonical USDC, ready to pay for gas and to trade.Details in Bridge.
Launchpad
Anyone can create a token that trades on a bonding curve — on-chain quotes, two-way trading, no transfers outside the curve until graduation. When the curve completes, graduation is permissionless (and rewarded): a constant-product pool opens on the exchange and the liquidity position is deposited into a locker that has no function to withdraw it. The position’s trading fees keep paying the creator for as long as the pool trades.Start from How the Launchpad Works.
Raise
Where projects run token sales: a project raises in dollars, on terms it defines for its own sale — price, allocation, schedule. It is a separate product from the launchpad: no bonding curve, no locker — the launchpad’s lock is the launchpad’s mechanism only. Lunya provides the infrastructure and does not review, select, or endorse any sale hosted on it. In development, not yet on testnet.Details in Raise.
Application stack
- Web app — swap, pools, launchpad, and token pages, one interface
- Indexer — a Ponder-based indexer exposing the GraphQL API that feeds the app: tokens, trades, 1m/1h candles
- Protocol console — internal control plane where every configurable parameter is read and changed in one place
