Overview
ArcYield wraps Arc-native assets into on-chain index vaults. One USDC deposit buys the whole class.
What ArcYield is
ArcYield is a set of index vaults on Arc, Circle's Layer-1 for the internet economy. Each vault holds a basket of assets that live natively on Arc: Circle's own stablecoins (USDC, EURC), the tokenized treasury fund USYC, and the tokenized instruments that list after them. Every one has a named issuer and an on-chain redemption path.
You deposit USDC, which is also Arc's gas token, and receive an ERC-4626 share token priced at NAV. The vault holds the constituents; the yield they throw off (treasury coupons, FX carry) is harvested and compounded into the basket every 24-hour epoch. Redemption is open at any time, at NAV, with no lockups and no gates.
Why Arc-native assets
Arc is built for stablecoin finance: USDC gas, sub-second deterministic finality, and Circle's issuance, FX and cross-chain rails wired in at the base layer. The assets that list here are the ones an institution would hold, and they arrive with issuer redemption instead of a liquidity pool as the floor. Indexing them means indexing the stablecoin economy itself, with the worst launchpad failure mode (a liquidity rug) never on the table.
The index does not pick winners. It holds every eligible asset in the registry, weighted by its float on Arc, with a hard 15% cap per constituent. Weight the cap cannot place stays in USDC.
