Celebrating Circle's Arc mainnet launch: DeepQA tests Arc ecosystem apps in place, with an injected test wallet on Arc testnet. Arc mainnet opened September 16, 2026.
The apps below are hosted web apps on Circle's Arc testnet. DeepQA tested each one in place at its public URL, in a real browser, with an injected test wallet that holds testnet funds only. No real funds were used. The findings cover functional and UX behavior as a user would meet it, not contract security or economics. A team that wants its report taken down can ask us and we will remove it.
