Working on a tool that unravels personal transaction history across wallets. Hand it an output and it looks up its trail through known wallets, resolving the original input. Result is a JSON file with structured data and a nice diagram, which looks funny for coins with collaborative transaction history (see screenshot). Bitcoin makes accounting sexy again. Based on Sparrow Wallet's BIP 329 export feature. h/t @craigraw image

GM. Finally found the time to finish and publish a first version of Bittrailer, which is now open source: - Finds UTXO trails across Sparrow wallet label exports (BIP 329). - Generates JSON and a flow chart for your personal coin history. - Privacy-focused accounting option, keeps your data offline.
