Polygon Portal

Polygon brings you a trustless two-way transaction channel between Polygon PoS and Ethereum by introducing the cross-chain bridge. The official bridge allows you to transfer tokens between Ethereum and Polygon PoS without incurring third-party risks and market liquidity limitations.

The official bridge is available on both the PoS Amoy testnet as well as mainnet, and provides a near-instant, low-cost, and flexible bridging option for both users and dApp developers. You can access it and bridge assets from Ethereum over to Polygon PoS using Polygon Portal.

There is no change to the circulating supply of your token when it crosses the bridge. This is what goes on in the background when you bridge your tokens over to Polygon PoS from Ethereum:

  • When depositing, tokens that leave the Ethereum network are locked and the same number of tokens are minted on Polygon PoS as a pegged token (1:1).
  • When withdrawing tokens back to the Ethereum network, tokens are burned on Polygon PoS and unlocked on Ethereum during the process.
