How to Transfer Assets to Polygon
A bridge is an easy way of porting assets from Ethereum to layer 2 solutions and sidechains. By being able to migrate funds from Ethereum L1 to L2s and other blockchains, you gain access to lower fees when interacting with different protocols.
Zapper currently only supports a one-way bridge from Ethereum to Polygon, but there are plans to make it a two-way bridge in the near future, including adding support for Ethereum L2s like Optimism and Arbitrum along with sidechain support like Binance Smart Chain, Fantom, and xDAI.
How to migrate assets from Ethereum to Polygon
- Go to Zapper Bridge
- Be sure your wallet is on the Ethereum network and that you specify the bottom destination network to be Polygon.
- Then choose a token to migrate from Ethereum to Polygon and what resulting token you'd like on Polygon. It is possible to start with a token like ETH and end up with a token like USDC. Zapper will perform a swap for you if you specify a different token to arrive on Polygon.
- Set the Transaction Speed according to how long you wish to wait for the confirmation on Ethereum. Once the transaction confirms on Ethereum, it will take an additional 7-8 mins for your assets to arrive on Polygon.
- Click Approve or Confirm. The approval is required if you're sending a token other than ETH, whereas ETH requires a single transaction. Notice the difference below when I deposit DAI into Polygon, requiring I "approve" spending my DAI.
- Monitor the status of your transaction confirming on Ethereum in the bottom right corner with our notifications. The notification will read "Success!" and turn green when confirmed on Ethereum. Then in about 5-8 mins, your assets will arrive in the same 0x wallet address on Polygon.
- If this is your first time using Zapper Bridge, you should find 0.01-0.001 MATIC deposited into your Polygon/Matic wallet to help pay transactions. However, this is a subsidy from the Polygon/Matic foundation for using the bridge for the first time, but if for some reason it doesn't show up, go to wallet.matic.network, be sure you're connected to Matic Mainnet and connect your wallet for the first time and you should receive 0.001 MATIC immediately. Another backup plan to receive free MATIC to get started on Polygon is to go to the Matic Faucet and you should receive 0.001 MATIC by connecting your wallet and following the prompts. MATIC is used to pay transaction fees like ETH is on Ethereum, except it's much less money.
