🔷EVM Compatibility

Overview

BitBadges Chain integrates the Cosmos x/evm module to enable Ethereum Virtual Machine (EVM) compatibility. Solidity contracts can interact with the tokenization module through precompiled contracts.

Architecture

Solidity Contract → EVM Precompile → Tokenization Module → Cosmos SDK State
