Submit mapping request

Token mapping is important in order to enable the transfer mechanism for the said token between Ethereum and Polygon PoS.

• For more information on how bridging works in the background, see the doc available here.
• Thinking about bridging another popular token? Refer to the reference guide on Polygon Portal.

Steps to submit a mapping request

1. To submit a request for mapping your token on Polygon PoS, start by navigating to the Google form available here.

2. Choose a Network option depending upon the chain on which you’re looking to map your token. This would be Sepolia <> Polygon Amoy for testnet, and Ethereum <> Polygon PoS for mainnet.

3. Next, input the contract address for the token contract that you’ve deployed on Sepolia/Ethereum mainnet in the Root Contract Address (L1) field.

4. Choose the correct Token Type for your token. i.e., ERC-20 for a standard token, ERC-721 for an NFT, or ERC-1155 for a multi token.

5. Finally, select Submit to send in your request. The Polygon team will review your mapping request, and get back to you with a response. This generally takes up to 7 days.
