False when the hash is malformed or the chain RPC reports the transaction was not found.

"unsupported_deposit_transaction"
Minimum threshold in the asset's atomic units when a verified deposit is ignored for being too small.
"10000"
Human-readable minimum threshold when a verified deposit is ignored for being too small.
"0.0001"
Known validation, not-found, conflict, or provider-check error returned with HTTP 200 for transaction-hash checks. Provider/RPC details are not exposed.
false
True when Stableyard recorded the observed deposit but did not create a transaction. Reusable USDC/USDT/USDG deposits are accepted at 0.5 tokens and above except Tron USDT, whose inclusive minimum is 10 USDT. Native BTC has an inclusive minimum of 0.0001 BTC (10,000 sats). Movement THBT is accepted at 16.5 or above. Polygon JPYC is accepted at or above the configured POLYGON_JPYC_MIN_AMOUNT (100 by default). Other native assets retain their documented strict minimum rules.
