Before you begin
Before starting your journey on ZKcandy, please be mindful of the following:
- ZKcandy is a Type-4 Zero Knowledge Ethereum Virtual Machine (ZKEVM) Rollup. This type of rollup is a high-level language-equivalent to the Ethereum Virtual Machine (EVM) but is not an equivalent tech stack. Be mindful of this when compiling contracts that target ZKcandy.
- ZKcandy is built using the Elastic Chain which is made popular by ZKsync. The semantics of this statement may seem to imply that ZKcandy is a Layer-3 blockchain. This is, however, NOT the case. ZKcandy is a Layer-2 which uses the Ethereum Mainnet for finality.
- The ZKcandy Sepolia Testnet, as the name implies, is a Layer-2 Testnet that uses the Ethereum Sepolia Testnet as its Layer-1.
- For all intents and purposes of this document, it is assumed that all deployments are performed using Externally Owned Accounts (EOA). If you are using a Contract Wallet, please refer to the documentation from your wallet provider.
