TxWorkshop
Inspect, build and sign txs
Free
Open any Cardano transaction and see exactly what it does — then fix it, sign it and send it.
TxWorkshop is 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.
INSPECT
• Open a transaction by pasting it, from a file, or by fetching it with its id or an explorer link
• Inputs, outputs, assets, mints, certificates, votes and proposals, laid out plainly
• Token names from the transaction's own metadata and the Cardano token registry
• Scripts as readable UPLC, redeemers and datums as trees, metadata with CIP labels
• Open any transaction, address, pool, DRep or asset in your choice of Cardanoscan, Cexplorer, AdaStat, Pool PM, PoolTool, DRepTalk or eUTxO
• Compare two transactions, and export as JSON, Markdown or a PDF report
CBOR AND CDDL
• A CBOR explorer that ties every item to its bytes, names each field and flags non-canonical encoding
• Edit bytes in place, with undo
• Check any item against the ledger's CDDL for its era, or against a schema you write
VALIDATE
• The ledger's Phase 1 rules and Plutus script evaluation, offline, from saved chain data
• Budgets per redeemer, a step-by-step script trace, and what-if runs with changed data
• Validate a whole folder of transactions at once
BUILD
• Build a transaction from outputs, mints, script inputs, certificates, withdrawals, votes and proposals
• Fees, collateral and script budgets worked out for you
SIGN AND SUBMIT
• Sign with keys from a recovery phrase, kept in the Keychain behind Face ID or Touch ID
• Sign with a Ledger, Trezor or Keystone hardware wallet
• Submit through Blockfrost, Koios, Ogmios or Yaci DevKit, and track confirmation
Your documents stay on your device. API keys and signing keys stay in the Keychain and are never written to a document.
