Arbitrum
Official Website: arbitrum.io
Arbitrum (ETH) is a Layer-2 network for Ethereum. A Layer-2 is a separate chain that processes transactions off of Ethereum's main chain and posts them back to it, giving you much lower fees and faster confirmations while inheriting Ethereum's security.
This wallet type supports the Arbitrum network. Do not send funds to or receive funds from other networks using this wallet.
Addresses
In Cake Wallet's Arbitrum 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 Arbitrum 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.
The 0x address format is the same across EVM chains, but the network is not. Make sure the sender uses the Arbitrum network. A token sent on the wrong network (for example Ethereum mainnet instead of Arbitrum) will not arrive.
Seed Format
Cake Wallet uses a 12-word BIP39 seed for Arbitrum 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.
Because Arbitrum 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.
Fees
Transaction fees are a necessary part of sending ETH or ERC-20 tokens.
ETH is consumed as a 'gas' fee when making any transaction from an Arbitrum wallet. This also applies to sending ERC-20 tokens. For example, to send USDT, you pay a network fee in ETH, not USDT. Thus, sending 10 USDT costs a small amount of ETH, and the recipient receives the full 10 USDT.
Arbitrum has no fee-level selector. Unlike Ethereum, Polygon, Base and BNB Smart Chain, Cake Wallet does not offer Slow / Medium / Fast for Arbitrum. The fee is set automatically from current network rates and cannot be changed.
A Fees row still appears under Advanced Settings on the send screen and shows the estimated fee. Tapping that row does nothing on Arbitrum — there is no fee picker to open.
MEV protection
Blink (MEV) protection is not available on Arbitrum. Cake Wallet's Blink protection covers Ethereum and Base only, so Arbitrum transactions are broadcast to the network normally.
Tokens
Cake Wallet's Arbitrum wallet can store ERC-20 tokens in addition to ETH. Some common tokens such as ARB, USDT, USDC, USDC.e, WBTC, and LINK 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.
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. Paste the address of the custom token you wish to add, then click the + button.
Transaction history
Transaction history is populated using the ArbiScan API. You can enable or disable this API lookup under ArbiScan History under Settings → Connections.
