Martify

NFT Marketplace on the Cardano Blockchain. Powered by Plutus Smart Contracts A simple contract that allows sales of NFTs. The seller (owner of an NFT) constructs the contract with parameters unique to the sale and locks the NFT there. A buyer can then unlock the NFT by submitting a transaction verifying the several requirements defined in the validator.

Test in emulator

Clone the repository
Run cabal repl in the repo
Run :l src/Market/Trace.hs in the repl
Run test
To modify the testing scenario, open and modify the src/Market/Trace.hs file

Test with `cardano-cli`

Put NFT for sale

Install and run a cardano-node on the testnet, you'll now have a node.socket file. Put the path to this file in the env variable CARDANO_NODE_SOCKET_PATH
Clone this repo https://github.com/nateshmbhat/cardano-nft-minter. It's an easy way to mint an NFT, so you can test and put it for sale
Execute the bash script and mint an NFT, selecting testnet
run testnet=testnet-magic 1097911063
run cd tokens/TokenName after you minted the NFT
run cardano-cli query utxo --address $(cat payment.addr) --$testnet
Note down the txhash and txid containing the NFT you minted
run cardano-cli address key-hash --payment-verification-key-file payment.vkey and copy the output
Go into the Martify repo after you built it using cabal build
run cabal run market-plutus
copy the resulting market.plutus file in the folder where you minted the NFT
run cabal run datum-json sellerAddr price tokenName policyId royaltyAddr royaltyPercent where sellerAddr is the output you copied previously, royaltyAddr should also be hash address (if you don't know, just put the same as sellerAddr and 0 for royaltyPercent)
copy the resulting file in the folder where you minted the NFT
go back to the folder where you minted the NFT
run cardano-cli address build --payment-script-file market.plutus --$testnet >> script.addr
run cardano-cli transaction hash-script-data --script-data-file datum-policyId-tokenname.json >> dhash
run

cardano-cli transaction build \
    --alonzo-era \
    --$testnet \
    --tx-in txhash#txid \
    --tx-out "$(cat script.addr) + 1724100 lovelace + 1 $(cat policy/policyID).tokenname" \
    --tx-out-datum-hash $(cat dhash) \
    --change-address $(cat payment.addr) \
    --protocol-params-file protocol.json \
    --out-file tx.02

cardano-cli transaction sign \
    --tx-body-file tx.02 \
    --signing-key-file payment.skey \
    --$testnet \
    --out-file tx-2.02

run cardano-cli transaction submit --tx-file tx-2.02 --$testnet

Cancel sale (adapt for other endpoints buy and update price)

run cardano-cli query utxo --address $(cat script.addr) --$testnet
Get the txhash and txid of your NFT for sale. We'll call those txhashNFT and txidNFT
run cardano-cli query utxo --address $(cat payment.addr) --$testnet
Get the txhash and txid of some ada at your wallet. We'll call those txhashADA and txidADA
Go into martify repo folder and copy over the close.json file from there
run

cardano-cli transaction build \
    --alonzo-era \
    --$testnet \
    --tx-in txhashADA#txidADA \
    --tx-in txhashNFT#txidNFT \
    --tx-in-script-file market.plutus \
    --tx-in-datum-file datum-policyid-tokenname.json \
    --tx-in-redeemer-file close.json \
    --required-signer payment.skey \
    --tx-in-collateral txhashADA#txidADA \
    --tx-out "$(cat payment.addr) + 1724100 lovelace + 1 policyid.tokenname" \
    --change-address $(cat payment.addr) \
    --protocol-params-file protocol.json \
    --out-file unlock-body.02

cardano-cli transaction sign \
    --tx-body-file unlock-body.02 \
    --signing-key-file payment.skey \
    --$testnet \
    --out-file unlock.02

run cardano-cli transaction submit --tx-file unlock.02 --$testnet
If everything went fine, you should see your asset in your wallet
