Before you begin
Can I paste only a transaction hash?
No. This tool works offline and does not query a blockchain. Supply a receipt object or the requested totals from a source you trust.
Does a successful receipt prove the transfer was safe or credited?
No. Execution status is a field in the copied record. It does not establish recipient identity, token delivery, exchange credit or current network inclusion.
Which networks and records are supported?
Ethereum-style JSON receipts using 18-decimal native units, and manual Bitcoin input/output totals in BTC with virtual size in vB. L2 data fees and contract event meanings are not automatically decoded.
What happens to my old Learning Path projects?
They keep their original editor, study progress and exports. New projects use Transaction Record Decoder.
Where are my projects saved?
Projects stay in this browser on this device. Download a JSON backup before changing devices or removing browser data. Keep passwords, private keys and recovery phrases out of every field.
