Shares a payout wallet with 1,051 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Given a Base address, check ETH/USDC balance, transaction activity, and contract status, with a low-risk/review/caution verdict for pre-payment counterparty screening.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
67

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
0

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 98% — how much probe evidence backs this score. A thin history is flagged, not hidden.
