VOLUME BY CHAIN ── 1 chain

Per-chain on-chain USDC settlement volume for this facilitator, with today (UTC), 7d, 30d and all-time windows, distinct buyers over 30 days (an upper bound) and a per-chain measured/listed state. Click a column header to sort.

Base USDC $0 $2.42 $23.82 $20.0k ≤ 98 2026-01-01 ● on-chain
● 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.

LISTED SERVICES SETTLING HERE ── 0 settling over 30d

All-time count pending the next hourly precompute.

Services listed in this directory that have settled on-chain via this facilitator, with each service's 30-day on-chain settlement volume, settlement count and its share of this facilitator's measured 30-day volume. Each service name links to its detail page. Click a column header to sort.
SERVICE VOL 30D SETTLEMENTS 30D SHARE OF 30D
No listed service has settled on-chain via this facilitator yet.
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 ── 9 ── 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.
