Unit Ethereum is deployed on both [HyperCore and the HyperEVM](https://hyperliquid.gitbook.io/hyperliquid-docs#technical-overview), and is fungible between these two execution environments. Users can [convert](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/hyperevm/hypercore-less-than-greater-than-hyperevm-transfers#transferring-between-core-and-evm) their tokens by transferring tokens to the [Unit Ethereum system address](#unit-ethereum-system-address).

* Convert from HyperCore to HyperEVM using a spotSend action (or via the frontend)&#x20;
* Convert from HyperEVM to HyperCore with an ERC20 transfer.&#x20;
