We've had a few people reach out asking how to import transactions from wallets and exchanges that Clams doesn't natively support. Clams has a "Custom" connection type built exactly for this. You can import any CSV and map the columns to match what Clams expects. The easiest path: use an LLM to help you create a reusable mapping so future imports are one click.
