The Graph’s x402 Stalls at $2.22 While Rail Hits $42.2M

$2.22 total agent payments for The Graph queries via x402 on Base — 222 payments, 29 ERC-8004 agents, stalled. Rail processed $42.2M. Three blockers: awareness, subgraph discovery, per-call settlement. Batch-settlement exists: deposit-once escrow, off-chain vouchers, batched claims. Fixes: market, adopt resolver, implement batch-settlement in graph-client (#1031).
