If you want to bridge tokens between the BNB Chain and the Polygon Mainnet you will need to use a secure and trusted bridging protocol like Synapse protocol. 

Synapse Protocol was established in August 2021 and has already had an impressive 10.5B in bridging volume. It is a universal cross-chain liquidity network that is available to use in every country. The platform has the largest bridging volume out of any Dapp (decentralised app) in DeFi.

Can I Bridge Crypto from Polygon to BNB Chain?

Yes, there are two options you can choose from to bridge between these two networks. The two bridging protocols you can use are Synapse Protocol and Allbridge. Allbridge charges pretty significant fees (around $40 - $50 AUD) and takes around 30 minutes to bridge funds. Synapse on the other hand only costs $10 AUD and takes under a minute to complete bridging. 

In addition to the speed and costs of bridging, Allbridge only allows you to bridge the following tokens - ABR, APYS, ARDN & HAPI. Synapse allows users to bridge the following tokens - USDC, USDT, DAI, gOHM, SYN, nUSD, BUSD, DOG, USDB & NFD.
