DeFi & Credit on Arc· 6
As of 28 September 2026, Built on Arc tracks 6 defi & credit projects on Circle's Arc blockchain: 4 live on mainnet, 0 on testnet, 2 announced. Aave, Maple and Morpho are the ones observed working on mainnet.
Lending markets, private credit, structured products and yield protocols with a named or observed deployment on Arc. Role here is almost always Deploys, so on-chain checks apply: contract verification, and the checks appropriate to the protocol's own design.
This category is deliberately narrow in scope. Built on Arc records status and links only — what has deployed, on which network, confirmed by what evidence, as of what date. It does not publish rates, does not compare returns and does not rank protocols by yield. Every question that starts "what does my USDC earn" belongs to DeFi & credit on Arc, which tracks live rates across Arc and is the right place to go from here.

Questions
Do you verify advertised yields?
No. Yield figures are the protocol's own claim. We record what is deployed, whether contracts are verified, and whether an audit is published.
Does an audit mean a protocol is safe?
No. An audit is a dated review by a named firm of a specific commit. We link it so you can read it. Nothing in this directory is a safety judgment.
Does paying change where a project appears?
No. Paid entries are labelled Listing, sit in the same ranked order as everything else, and use rel="sponsored". Payment never affects status, flags, evidence or the Editor's Index.
