Role
Integrating Arc into an existing product · 82
These companies are wiring Arc into a product or a rail that already exists: a payment processor adding a settlement option, a bank testing transfers, an exchange enabling the network, a card programme funding spend from an on-chain balance. They usually deploy nothing themselves, so there are no on-chain checks — that is a property of the role, not a gap. What matters instead is whether the integration is available to real customers, which is exactly what the status and its dated evidence record.

Questions
Why are there no on-chain checks on these entries?
Integrators generally deploy no contracts of their own. Showing empty checks would be misleading, so nothing is rendered.
How is status decided?
Status reflects what we observed on the date shown, not what a project announced. Every entry carries a dated source you can open and check yourself. Live can become Inactive if activity stops.
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.
