# Ethereum key management Currently, `%fund` associates ethereum wallets for workers and oracles by the on-chain instantiation of the escrow contract, or in the case of project funding transactions, a trust but verify model. This linkage of Ethereum address and Urbit ID is straightforward, but is likely to expand in the future to enable additional features such as "Refund to my Urbit" or "Verified Project History". In the current implementation, our main statement is relatively typical of crypto: * **Not your keys, not your coins**. So keep your keys private and secure. If you are interested in utilizing more complex mechanisms of associating your urbit ID, your ethereum keys, and your work or contribution history with each other—either on- or off-chain—let us know! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
