Who is CoinLedger for?
CoinLedger is suited to users looking for tax form generation and tax software integrations on Core Blockchains. Its documented workflow includes wallet funding and balance management.
Before you use it
- Users must not mistake CoinLedger for a trading terminal, DEX aggregator, or memecoin execution tool.
- The documentation cautions that missing historical transfers, unmapped smart contract interactions, or failure to import data from *all* utilized platforms will result in inaccurate cost-basis calculations and flawed tax reports.
- Certain integrated networks are flagged in documentation as "Archived & Limited Support Networks"—meaning they are no longer actively updated or only support historical imports up to a specific cutoff date.
