Submit mapping request
Token mapping is important in order to enable the transfer mechanism for the said token between Ethereum and Polygon PoS.
Info
- 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¶
-
To submit a request for mapping your token on Polygon PoS, start by navigating to the Google form available here.
-
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.
- Next, input the contract address for the token contract that you’ve deployed on Sepolia/Ethereum mainnet in the “Root Contract Address (L1)” field.
- 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.
- 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.

- Once approved, your token will be added to the above list!
