Casper NFT Quick Installation Guide
This quick installation guide introduces you to the Casper client commands and Wasm files necessary to deploy a CEP-78 Casper Enhanced NFT contract to the Casper Testnet. For greater detail into the creation and mechanics of the Casper NFT contract, see the complete Casper NFT Tutorial.
To execute transactions on a Casper network involving NFTs, you will need some CSPR tokens to pay for the transactions. The Testnet provides test tokens using a faucet.
Prerequisites
Before using this guide, ensure you meet the following requirements:
- Set up the development prerequisites, including the Casper client
- Get a valid node address from the network
- Know how to install a smart contract on a Casper network
- Hold enough CSPR tokens to pay for transactions
Setup
Clone the Casper NFT (CEP-78) contract repository.
git clone https://github.com/casper-ecosystem/cep-78-enhanced-nft/ && cd cep-78-enhanced-nft
Run the following commands to build the contract.wasm in the contract/target/wasm32-unknown-unknown/release directory and run the tests.
make prepare
make test
The output of the command would end with the following message:
test result: ok. 159 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 15.33s
Installing the NFT Contract
The following command will install a sample NFT contract on the Testnet:
casper-client put-deploy --node-address http://localhost:11101/rpc/ \
--chain-name "casper-net-1" \
--payment-amount 5000000000 \
--secret-key ~/casper/casper-node/utils/nctl/assets/net-1/nodes/node-1/keys/secret_key.pem \
--session-path contract/target/wasm32-unknown-unknown/release/contract.wasm \
--session-arg "collection_name:string='CEP-78-collection'" \
--session-arg "collection_symbol:string='CEP78'" \
--session-arg "total_token_supply:u64='100'" \
--session-arg "ownership_mode:u8='2'" \
--session-arg "nft_kind:u8='1'" \
--session-arg "nft_metadata_kind:u8='0'" \
--session-arg "json_schema:string='nft-schema'" \
--session-arg "identifier_mode:u8='0'" \
--session-arg "metadata_mutability:u8='0'"
