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

Read-only EVM state API for wallet snapshots, ERC-20 balances, token allowances, contract code, block heights, and bounded eth_call reads across Ethereum, Base, Arbitrum, Optimism, and Polygon. Fixed price: $0.15 USDC on Base for a batch of up to 100 checks. Only submitted checks run. Results are provider-reported RPC data, not cryptographic proofs.

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

Availability: 85
Latency: 100
Security: 100
Transparency: 61
Activity: 7

Confidence 40% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 2 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator
