Solidity Compatibility

PNCMainnet is designed to be EVM equivalent (opens in a new tab), which means PNCMainnet looks exactly like Ethereum in every way possible. Almost all Ethereum tooling works out of the box on PNCMainnet, including the Solidity (opens in a new tab) smart contract language. However, there are a few minor differences between PNCMainnet and Ethereum that you should be aware of when building Solidity contracts.

EVM/Opcode Differences

Most smart contracts will work on PNCMainnet without any changes. Check out the Differences Between Ethereum and PNCMainnet page for a detailed list of the few differences you should know about.

Gas Differences

PNCMainnet uses the same gas costs as Ethereum. However, PNCMainnet also charges an L1 Data Fee for the cost of publishing an L2 transaction to L1. This fee is charged based on the size of a transaction in bytes. As a result, smart contract optimization techniques can differ slightly on PNCMainnet. Refer to the Contract Optimization guide for more information.
