# Ethereum

Unit Ethereum Mainnet Token Information

Ethereum deposits and withdrawals are supported between HyperCore and Ethereum mainnet. Destination transactions are credited from Unit's respective treasury address.

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;

***NOTE:*** Due to the requirements of the orderbook, ETH has 9 `wei decimals` on HyperCore. It is recommended to only specify up to 9 decimal places (Gwei-level precision) when converting HyperEVM to HyperCore. Beyond this, the [non-round amount is burned](https://hyperliquid.gitbook.io/hyperliquid-docs/for-developers/hyperevm/hypercore-less-than-greater-than-hyperevm-transfers#caveats) (guaranteed to be < 1 Gwei). This is true for all spot tokens, including HYPE.
