EVM Precompiles on 0G Chain
EVM (Ethereum Virtual Machine) precompile contracts are special, built-in contracts provided by the Ethereum protocol to perform specific, commonly-used operations more efficiently than if they were implemented in Solidity or another high-level language.
The current version of 0g chain supports the Istanbul version of the EVM and all the EVM precompiles it includes(check it out here). In addition to the native EVM precompiles, we have also defined additional precompile contracts to enable modifying the state of Cosmos modules through EVM transactions:
Interact with 0G Precompiles in Smart Contracts
Calling 0g precompiles in a contract can be a bit tricky. Since some of the newly added precompiles are stateful, interacting with their non-read-only functions in a contract requires using a low-level call. The mint function of WA0GI can be used as a reference for implementation.
