cardano-cli-transactions-operator

OPERATOR SKILL: This skill executes commands including transaction submission. Requires explicit human invocation.

When to use

• When ready to build and submit a transaction
• After reviewing guidance from cardano-cli-transactions

Operating rules (must follow)

• Confirm network before ANY operation
• Show full transaction details before signing
• REQUIRE explicit "yes" confirmation before submit
• Create tx bundle folder for reproducibility
• Verify UTxO changes after submit

Pre-flight checklist

[ ] Network confirmed: ___________
[ ] Sender address verified
[ ] Recipient address verified (check first/last 8 chars)
[ ] Amount confirmed: ___________ lovelace
[ ] Signing key path confirmed
[ ] UTxO inputs selected

Execution workflow

Step 1: Setup tx bundle

TX_DIR="tx-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$TX_DIR" && cd "$TX_DIR"

Step 2: Query UTxOs

cardano-cli conway query utxo \
  --address <sender-addr> \
  --testnet-magic 1 \
  --out-file utxos.json

Step 3: Fetch protocol parameters

cardano-cli conway query protocol-parameters \
  --testnet-magic 1 \
  --out-file pparams.json

Step 4: Build transaction

cardano-cli conway transaction build \
  --testnet-magic 1 \
  --tx-in <utxo>#<index> \
  --tx-out <recipient>+<amount> \
  --change-address <sender> \
  --out-file tx.unsigned

Step 5: Sign (show what's being signed)

echo "=== SIGNING TRANSACTION ==="
echo "Inputs: <utxo>"
echo "Output: <recipient> receives <amount> lovelace"
echo "Change: returns to <sender>"

cardano-cli conway transaction sign \
  --tx-file tx.unsigned \
  --signing-key-file <payment.skey> \
  --testnet-magic 1 \
  --out-file tx.signed

Step 6: Submit (REQUIRES CONFIRMATION)

⚠️  CONFIRM SUBMISSION ⚠️
Network: preprod
Sending: X ADA to addr_test1...
From: addr_test1...

Type 'yes' to submit:

cardano-cli conway transaction submit \
  --testnet-magic 1 \
  --tx-file tx.signed

Step 7: Verify

# Get tx hash
cardano-cli conway transaction txid --tx-file tx.signed

# Query recipient UTxO
cardano-cli conway query utxo \
  --address <recipient> \
  --testnet-magic 1

Safety / key handling

• Never submit without explicit user confirmation
• For mainnet: require double confirmation
• Keep tx bundle for audit trail
• Recommend small test tx first on mainnet
