TxWorkshop

A workbench for Cardano transactions. Open one, see exactly what it does, check it against the ledger's rules, change it, sign it and send it.

Download for Mac App Store — coming soon Read the guide

On Mac, iPhone, iPad and Apple Vision Pro. The Mac download adds a local cardano-node and cardano-cli, which the App Store doesn't allow. It needs macOS 27, and keeps itself up to date. Or install it with Homebrew:

brew install --cask kingpin-apps/tap/cardano-txworkshop

What it does

Inspect

Inputs, outputs, assets, mints, every certificate field, votes, proposals, scripts and metadata, laid out plainly, with token names and links to your block explorer.

CBOR and CDDL

Every item tied to its bytes, each field named, non-canonical encoding flagged, and any item checked against the ledger's schema for its era.

Validate

The ledger's Phase 1 rules and Plutus script evaluation, offline, with budgets per redeemer, a script trace, what-if runs, and a check that hardware wallets can sign it (CIP-21).

Build

Outputs, mints, script inputs, every Conway certificate, withdrawals, votes and proposals, from the UTxOs you choose. Addresses, pools and keys in any form, typed or from files; datums and redeemers as typed forms from a blueprint.

Debug scripts

Step through a Plutus script's run, forwards and back, with its variables, stack, budget and traces, breakpoints, and a redeemer to try instead.

Chain data

The tip, epoch, era and protocol parameters, and the UTxOs a transaction spends, fetched once and kept in the document for offline work.

Sign

Keys from a recovery phrase, kept in the Keychain behind Face ID or Touch ID, or a Ledger, Trezor or Keystone hardware wallet.

Submit

Through Blockfrost, Koios, Ogmios, Yaci DevKit, or, on the Mac download, your own cardano-node or cardano-cli. Then track confirmation.
