Zinc Playground

In order to learn what I can do on zkSync and how I can develop smart contracts on zkSync, I put my progress in this repository. For now, I try to develop contracts of ERC20, ERC721, and NFTMarket on zkSync Rinkeby testnet.

zkSync is a Layer-2 solution for Ethereum using zk rollup. This platform is going to allow developers to write smart contracts with Zinc Language. It is a vering promising project. Many DeFi protocols have join this ecosystem.

Zinc is an emerging framework for developing smart contracts and SNARK circuits on the zkSync platform.

How to use

1. Install Zinc from here
2. Go to folders in which you are interested, e.g. /erc20.
3. Change an unique contract name in Zargo.toml file.
4. Compile smart contracts by running zargo build.
5. Setting parameters in **/data/input.json.
6. Deploy smart constracts by running zargo publish --network rinkeby --instance default.
7. Query the contract storage by running zargo query --network rinkeby --address <contract-address> or zargo query --network rinkeby --address <contract-address> --method <method-name>.
8. Call the contract method by running zargo call --network rinkeby --address <contract-address> --method <method-name>.

Workaround solutions for some issues

This issues may be fixed or removed when offical team releases turing-compelte version of Zinc language.

• store string
• allowances mapping
• store IPFS hash using Uint8Array
• Intrinsic function: transfer
• asset porting between L1 and L2
