Where to Bridge Crypto from Optimism to Polygon

Synapse is the only bridging protocol that supports both the Optimism and Polygon networks. You can bridge directly between the two chains and send/recieve the following tokens - USDT, USDC, DAI, nUSD, gOHM & SYN. If you need any of the above-mentioned tokens you can utilise the ‘Swap’ (trade) feature on Synapse to exchange your current tokens for the ones available.

In addition to bridging and trading tokens, you can also stake cryptocurrencies on the Synapse protocol. They are one of the only DEXs (decentralised exchange) to offer cross-chain staking, meaning you can stake multiple assets across 15 different networks. This is a unique feature only available on Synapse.

Bridging Fees: Optimism & Polygon

To bridge between Optimism and Polygon on Synapse protocol, the total cost will be around $5 - $10AUD. On most major bridges this will cost around $30 - $50 AUD as you cannot directly bridge between networks on any other DEX or Dapp (decentralised app). Synapse is the only bridge that supports direct bridging between the two networks hence the competitively low price.
