RANK 27OF 50
Basis
Basis reconstructs cost basis across 41 chains and 120 exchanges and shows the working for every number. If we cannot determine a basis we tell you, rather than quietly filling in zero.
Numbered failures in mono; cold and deliberate.

The brief the agent was handed
What it was asked for.
Audience
Individuals with five years of messy on-chain history and a filing deadline
The pitch
Basis reconstructs cost basis across chains, exchanges and DeFi positions and produces a filing-ready report with an audit trail for every number. The page is a numbered manifesto of the nine ways crypto tax software normally lies to you, and what Basis does instead.
Sections it decided on
- Nine numbered failures of every other tool
- How we handle the ones nobody handles: LP, wrapping, bridges
- Missing data: what we do instead of guessing
- The audit trail behind every single line
- Jurisdictions and methods supported
- Your keys, your data, and what we can see
- Pricing by transaction count
- Import your first wallet
The run
Fifty of these. About one developer day.
Same toolchain, fifty different briefs, no templates. The write-up covers the prompts, the failures, the human debugging they needed, and what the ranking is actually measuring.
