It offers low fees and fast blocks, and supports the same ERC-20 token standard used on Ethereum (often called BEP-20 on this chain). This wallet type supports the **BNB Smart Chain** (BSC) network. Do not send funds to or receive funds from other networks using this wallet. ## Addresses In Cake Wallet's BNB Smart Chain wallet, there is only one address per wallet, which is standard for the Ethereum ecosystem. Keep in mind that this has lesser privacy compared to some other assets, where new addresses are automatically generated. Your BNB Smart Chain address starts with `0x` followed by a series of alphanumeric characters. This is the same `0x` address format used on Ethereum and other EVM chains, so the same address can receive funds on many chains. {% hint style="warning" %} The `0x` address format is the same across EVM chains, but the network is not. Make sure the sender uses the **BNB Smart Chain** network. A token sent on the wrong network (for example Ethereum mainnet instead of BNB Smart Chain) will not arrive. {% endhint %} ## Seed Format Cake Wallet uses a 12-word BIP39 seed for BNB Smart Chain 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`. {% hint style="info" %} Because BNB Smart Chain shares the same seed format and derivation path as Ethereum, its seed can be shared with your other Cake Wallet currencies as part of a [wallet group](https://docs.cakewallet.com/features/managing-your-wallet/wallet-groups). {% endhint %} ## Fee Levels Transaction fees are a necessary part of sending BNB or ERC-20 tokens. BNB is consumed as a 'gas' fee when making any transaction from a BNB Smart Chain wallet. This also applies to sending ERC-20 tokens. For example, to send USDT, you pay a network fee in BNB, not USDT. Thus, sending 10 USDT costs a small amount of BNB, and the recipient receives the full 10 USDT. Cake Wallet offers three fee levels for transactions: * **Slow**: Cheaper but may take longer to confirm. * **Medium**: Recommended for most transactions. Balanced speed and cost. * **Fast**: Expensive but confirms quickly. These fee levels are determined automatically using current network fee rates. ## MEV protection Blink (MEV) protection is **not** available on BNB Smart Chain. Cake Wallet's Blink protection covers Ethereum and Base only, so BNB Smart Chain transactions are broadcast to the network normally. ## Tokens Cake Wallet's BNB Smart Chain wallet can store ERC-20 tokens in addition to BNB. Some common tokens such as USDC, ETH, USDT, and USDe are displayed by default. To show other tokens, open the `Assets` tab on your home screen, tap the `Tokens` button, and enable them. ### 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 BSCScan API. You can enable or disable this API lookup under `BSCScan History` under `Settings` → `Connections`. --- # Agent Instructions This documentation is published with GitBook.

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/bnb-smart-chain.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.
