Circle's Arc plugs Morpho Vaults into Earn Kit SDK for USDC yield
- —Earn Kit SDK routes USDC and EURC into curated Morpho Vaults without custom smart contracts
- —Day-one deposits exceeded $150 million across USDC and EURC vaults
- —Vault curators include Steakhouse Financial and Galaxy, with ETH and BTC collateral
- —Mainnet deployment is expected by late September 2026; testnet is live
Why it matters: The SDK lowers the barrier to embedding stablecoin yield in apps, potentially accelerating capital inflows into Arc and Morpho's credit layer.
