Compability

Solidity Compatibility

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

EVM/Opcode Differences

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

Gas Differences

OP Mainnet uses the same gas costs as Ethereum. However, OP Mainnet 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 OP Mainnet. Refer to the Contract Optimization guide for more information.
