Unlike Bitcoin, which is primarily a digital currency, Ethereum provides a more versatile platform allowing developers to build various types of decentralized applications (dApps), and supports token standards such as ERC-20. This wallet type **only** supports sending on the **Ethereum** network. Do not attempt to receive other networks to this wallet, or send funds to other networks. ## Addresses In Cake Wallet's Ethereum wallet, there is only one address per wallet, which is standard for the Ethereum ecosystem. Keep in mind that this will have lesser privacy compared to some other assets, where new addresses are automatically generated. Your Ethereum address will start with `0x` followed by a series of alphanumeric characters. ## Seed Format Cake Wallet uses a 12-word BIP39 seed for Ethereum wallets by default. Under `Advanced Settings` on the wallet creation screen you can choose a **24-word** BIP39 seed instead, and you can add a seed passphrase. When creating or restoring a wallet, you can use the seed phrase or the private key. The derivation path used is `m/44'/60'/0'/0`. ## Fee Levels Transaction fees are a necessary part of sending Ether or ERC-20 tokens. Ether (ETH) is consumed as a 'gas' fee when making any transaction from an Ethereum wallet. This also applies to sending ERC-20 tokens. For example, to send USDT, you need to pay a network fee in ETH, not USDT. Thus, sending 10 USDT will cost a certain amount of ETH, and the recipient will receive the full 10 USDT. Cake Wallet offers three fee levels for transactions: 1. **Slow**: Cheaper but may take longer to confirm. 2. **Medium**: Recommended for most transactions. Balanced speed and cost. 3. **Fast**: Expensive but confirms quickly. These fee levels are determined automatically using current network fee rates. We recommend using the `Medium` fee level under normal conditions for a good balance of speed and cost. Ethereum has two components to fees: the `base` component set as the network minimum, and the `priority` component. By changing the Cake Wallet fee level, you add or remove from this `priority` value. The `base` fee component does not change. ## MEV protection When you send an Ethereum transaction, Cake Wallet broadcasts it privately through [Blink](https://blinklabs.xyz/) rather than the public mempool. This protects your transaction from MEV — "maximal extractable value" attacks such as front-running and sandwiching, where bots watch the public mempool and reorder or insert transactions around yours to profit at your expense. Blink protection is enabled by default. If a private broadcast ever fails, Cake Wallet automatically falls back to a normal broadcast so your transaction still goes through. You can turn it off with the `Use Blink Protection` toggle under `Connections` in settings. ## Tokens Cake Wallet's Ethereum wallet can store ERC-20 tokens in addition to ETH. Some common ERC-20 tokens such as USDC, USDT, DAI, and DEURO (Decentralized Euro) are displayed by default. To show other ERC-20 tokens, open the `Assets` tab on your home screen, tap the `Tokens` button, and enable them. Other token types, as well as NFTs, are not currently supported; expanded support is planned for the future. ### Adding a new token You can add a new ERC-20 token from the same `Tokens` screen: search for your desired token, then tap to enable it. If the token does not appear, you can add it by [contract address](https://docs.cakewallet.com/features/advanced/add-custom-tokens). Paste the address of the custom token you wish to add, then click the `+` button. ## Transaction history Transaction history is populated using the Etherscan API. You can enable or disable this API lookup in **Connections** settings. ## Features for Ethereum * [Bridge USDT between chains](https://docs.cakewallet.com/features/basic/bridge-usdt-between-chains) — move USDT between Ethereum, Polygon, and Arbitrum directly in-app. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.cakewallet.com/cryptos/ethereum.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
