answers 402
Read the current on-chain JPYC balance of any EVM address on one or all supported chains (Polygon, Kaia, Avalanche, Ethereum), with the token contract and the block number observed at request time. Use before or after a payment, for treasury checks, wallet monitoring, and payment reconciliation. The result does not prove wallet ownership and is not a transaction-finality certificate.
