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.
