Polygon
Official Website: polygon.technology
Polygon (POL) is a Layer-2 network for Ethereum that is designed to support a much higher TPS (transactions per second) while having significantly lower fees than Ethereum itself.
This wallet type only supports sending on the Polygon network. Do not attempt to receive other networks to this wallet, or send funds to other networks.
Addresses
In Cake Wallet's Polygon wallet, there is only one address per wallet, which is standard for the Polygon ecosystem. Keep in mind that this will have lesser privacy compared to some other assets, where new addresses are automatically generated.
Your Polygon address will start with 0x followed by a series of alphanumeric characters.
Seed Format
Cake Wallet uses a BIP39 seed for Polygon wallets — 12 words by default, with a 24-word option available under Advanced Settings when you create a wallet. You can also add an optional seed passphrase there. When creating or restoring a wallet, you'll 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 POL or ERC-20 tokens.
POL is consumed as a 'gas' fee when making any transaction from a Polygon wallet. This also applies to sending ERC-20 tokens. For example, to send USDT, you need to pay a network fee in POL, not USDT. Thus, sending 10 USDT will cost a small amount of POL, and the recipient will receive 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 Polygon. Cake Wallet's Blink integration covers Ethereum and Base only, so Polygon transactions are broadcast to the network in the usual way.
Tokens
Cake Wallet's Polygon wallet can store ERC-20 tokens in addition to POL. Some common ERC-20 tokens such as USDT, USDC, USDC.e (bridged USDC), DAI, and DEURO (Decentralized Euro) are displayed by default. To show other ERC-20 tokens, open the Assets tab on the home screen, tap Tokens, and enable the ones you want.
Other token types beyond ERC-20 are not currently supported. NFTs do show in the app: your Polygon NFTs appear in the NFTs tab on your home screen (view-only for now — sending NFTs is currently available on Solana wallets; see Solana).
Adding a new token
You can add a new ERC-20 token by opening the Assets tab on the home screen and tapping Tokens, then searching for your desired token. Tap it 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 tap the + button.
Transaction history
Transaction history is populated using the PolygonScan API. You can enable or disable this API lookup in Connections settings.
