Overview
The ERC20 extension bridges Ethereum’s de facto token interface into the native Cosmos token model. This allows existing DeFi contracts and tooling to interoperate with Cosmos-native assets seamlessly. Each native Cosmos denomination registered as a token pair gets a dynamically assigned ERC-20 address. Standard ERC-20 methods (balanceOf, transfer, approve, transferFrom, allowance) work as expected.
Address: Dynamic per token pair
Standard ERC-20 Interface
How It Works
Native Cosmos tokens are registered as token pairs linking a Cosmos denomination to an ERC-20-compatible address. When you interact with the ERC-20 interface, the extension translates operations to the underlyingx/bank module, so balances remain consistent across both interfaces.
