Sign a Cardano transaction with multiple keys. Each key corresponds to one input:

Create a Cardano blockchain transaction to transfer ada cryptocurrency:

Sign the transaction with a PrivateKey object:

Submit the transaction to the Cardano blockchain:

Verify the transaction using its "TransactionID":

Create a Cardano blockchain transaction to mint 1,000,000 tokens and send them to multiple addresses:

Alternatively, a single output is allowed to have "Amount" set to Automatic to have any remaining tokens sent to that address:

Sign the transaction with PrivateKey objects:

Submit the transaction to the Cardano blockchain to mint the tokens:

Verify the transaction using its "TransactionID":

Generate an image to mint it as an NFT:

Upload the image to IPFS and save its CID:

Prepare the NFT metadata following the CIP 25 standard:

Create the Cardano blockchain transaction to mint the NFT:

Obtain a compiled Plutus script:

This particular script succeeds if, and only if, the redeemer's script data is a list of prime factors of the datum. For the datum, choose 221 as an arbitrary semi-prime. Script data must conform to Cardano's detailed JSON schema:

Deploy Plutus scripts with a datum hash by specifying within the "Outputs" list an "Address" pointing to a script file and a "Datum" with "Data" pointing to a script data file and using the "Hash" mode:

Sign the transaction with a PrivateKey object:

Submit the transaction to the Cardano blockchain:

Verify the transaction using its "TransactionID":

Spend a Plutus script using the "Redeemer", "Datum" and "Script" elements in the "Inputs" list and specifying collateral inputs in "CollateralInputs":

Notice that execution units were calculated automatically:

Sign the transaction with a PrivateKey object:

Submit the transaction to the Cardano blockchain:

Verify the transaction using its "TransactionID":

Obtain a compiled Plutus script:

This particular script succeeds if, and only if, the spending transaction is signed by the private key associated with the public key hash included in the deployed datum:

Deploy a Plutus script with a datum hash by specifying within the "Outputs" list an "Address" pointing to a script file and a "Datum" with "Data" pointing to a script data file and using the "Hash" mode:

Sign the transaction with a PrivateKey object:

Submit the transaction to the Cardano blockchain:

Spend Plutus scripts that have required signers by specifying them with a PrivateKey object, a PublicKey object, an address or a public key hash within the "RequiredSigners" list:

When automatic execution units are requested and the script requires signers, calculation of required signers is delayed until the transaction is signed. Sign the transaction using a PrivateKey object:

The automatic execution units have now been calculated:
