Creating an NFT

Following steps allow to create an NFT using a minting policy of type Time-locked in testnet.

Location of files

• Keys for payment address are located on /key1
• Keys for policy are located on main folder

Steps

1. Upload to ipfs

curl "https://ipfs.blockfrost.io/api/v0/ipfs/add" \
  -X POST \
  -H "project_id: ipfsWRpGJnKjMALDhlHZc13mPzpK11eeqRom" \
  -F "file=@./nano.png"

2. Pin it

curl "https://ipfs.blockfrost.io/api/v0/ipfs/pin/add/QmWZ5BxqaE4XV6Z5HavTJHdazL2tYdF6MraFGJAh2ZY6r6" \
  -X POST \
  -H "project_id: ipfsWRpGJnKjMALDhlHZc13mPzpK11eeqRom"

3. Create a policy key

cardano-cli address key-gen \
    --verification-key-file policy.vkey \
    --signing-key-file policy.skey

4. Hash of the verification key file

cardano-cli address key-hash --payment-verification-key-file policy.vkey

Hash: e06e4bd41e01aa5449a9c18ea444d21bdb12f1a1a90ab087805ebc76

5. Find the slot in the testnet

cardano-cli query tip --testnet-magic 1097911063

or using https://explorer.cardano-testnet.iohkdev.io/

6. Build the policy.json: https://github.com/input-output-hk/cardano-node/blob/master/doc/reference/simple-scripts.md

7. Hash of the policy script

cardano-cli transaction policyid --script-file policy.json > policy.id

Policy id: 8f7633ebcf477753565e87f69e1d9c791bc39adccd10390f33720ab3

8. Define metadata.json including the policy id
9. Get protocol parameters

cardano-cli query protocol-parameters --testnet-magic 1097911063 --out-file protocol-params.json

10. Query UTxO

cardano-cli query utxo --address $(cat key1/payment.addr) --testnet-magic 1097911063

11. Build transaction

cardano-cli transaction build-raw \
  --fee 0 \
  --tx-in 722f716a16286dfaf21925e7f7013f2e8248223ed8f04b455c9a745751a4c6d9#0 \
  --tx-out $(cat key1/payment.addr)+200000000+"1 $(cat policy.id).nano0001" \
  --mint="1 $(cat policy.id).nano0001" \
  --minting-script-file policy.json \
  --metadata-json-file metadata.json \
  --invalid-hereafter=40590754 \
  --out-file transaction.raw

12. Calculate min fee

cardano-cli transaction calculate-min-fee \
  --tx-body-file transaction.raw \
  --tx-in-count 1 \
  --tx-out-count 1 \
  --witness-count 2 \
  --testnet-magic 1097911063 \
  --protocol-params-file protocol-params.json

Min fee: 194541 Lovelace Change: 200000000 - 194541 = 199805459

13. Build final transaction using fees and change

cardano-cli transaction build-raw \
  --fee 194541 \
  --tx-in 722f716a16286dfaf21925e7f7013f2e8248223ed8f04b455c9a745751a4c6d9#0 \
  --tx-out $(cat key1/payment.addr)+199805459+"1 $(cat policy.id).nano0001" \
  --mint="1 $(cat policy.id).nano0001" \
  --minting-script-file policy.json \
  --metadata-json-file metadata.json \
  --invalid-hereafter=40593754 \
  --out-file transaction.raw

14. Sign the transaction

cardano-cli transaction sign \
  --signing-key-file key1/payment.skey \
  --signing-key-file policy.skey \
  --testnet-magic 1097911063 \
  --tx-body-file transaction.raw \
  --out-file transaction.signed

15. Submit the transaction

cardano-cli transaction submit \
  --tx-file transaction.signed \
  --testnet-magic 1097911063

16. Confirm transaction from testnet.cardanoscan.io
