How to bridge from Avalanche to Polygon

AVAX to Polygon Bridging Fees

When bridging USDC or any token from the Avalanche C-Chain network to the Matic Mainnet, you will need to consider the bridging and network transaction (gas) fee. Both transactions will cost you up to $5 AUD to move your funds over to the Polygon network. We recommend Synapse as its fees are cheaper than competitors like Stargate Finance by around 0.5% per transaction.


To conclude, bridging funds between Avalanche and Polygon is a relatively straightforward process with the right tools. Synapse Protocol is arguably one of the best platforms to bridge your tokens with, providing low fees and secure transfers of assets across both networks. It also is one of the only bridging platforms that provide live customer support.
