● on-chain = measured directly from settlement transactions ── ○ listed = chain declared by a settler address, not yet measured ── Distinct buyers are counted per chain from the daily snapshots. A buyer active on more than one day is counted once per active day, and buyers on different chains or tokens are not de-duplicated, so total_upper_bound_30d is an upper bound, not an exact head count. Prefer the per-chain figures.

Services listed in this directory that have settled on-chain via this facilitator. Volume is the service 30d figure over its payout mapping (a conservative floor, USDC via measured facilitators only); services that share a payout address are counted at the address level here. The all-time count is null until the hourly precompute records it.

SETTLER EOAS ── 6 ── each links to its full on-chain activity on the relevant explorer

On-chain settler addresses (EOAs) for this facilitator, with the chain they settle on, discovery source, token, the date the discovery source last reported the address (NOT an on-chain measurement: on-chain activity can be more recent), and enabled status. Each address links to its full token activity on the relevant block explorer. Click a column header to sort.
