I’m the developer of DexLadder, a browser-based Web3 learning and paper-trading environment. One feature I wanted was a “show your work” surface instead of asking people to trust a dashboard. The Verify desk registers formulas with inputs, units, references and source notes, then computes each result step by step and runs an alternative implementation. The Check tab prints intermediates and the delta between the two routes. Cross-checks compare selected figures with neighbouring desks, and export produces the inputs, formula text, expected outputs, tolerances and citations for independent review. The boundary matters: passing arithmetic checks does not prove that market inputs are truthful, complete or current. DexLadder is paper/simulation software, not a trading venue or an attestation service. No wallet connection, no deposits, no withdrawals, and no financial advice. I’d love feedback from other builders: would you rather see more formulas, more fixtures, or more adversarial refusal cases when inputs are missing? https://www.dexladder.com/   submitted by   /u/Appropriate-Top-5134 [link]   [comments]
