It costs 15 - 20USD for regular crosschain (L2 back to ETH mainnet) and transferred to another L2 costs another 15-20USD.

This is Synthetix bridge.

from Matic on polygon to SUSD on Optimism. This includes converting and crosschain bridge.

129 Matic * 0.75USD (the price as of July 20/2023) = 97.5 USD

As you can see this crosschain bridge + converting token does not affect the original value. Great.

There are 5 chains for now, which is good for now.

It would cost around 20USD from Matic back to Ethereum without converting the token and it estimates 3 hours to finish.

This is Iron bank. Powered by Li Fi.

Transferred from Polygon USDC to Optimism SUSD, that resulted 193 USD tp 192 USD. Great. It took about 15mins to complete.

Ironbank offers many chains.

If you transferred back from Optimism to Ethreum and it costs 15USD and it takes a week.
