Testnet or Mainnet?
We have a mainnet fork(s) simulation environment for testing cross chain transactions with Squid. Get in touch if you would like to use it. We strongly recommend this method. Docs coming soon.
The prices on Testnets are not realistic, so you can end up with swaps and bridges which look like 1 ETH --> 0.0000006 ETH. This is because Squid works by accessing DEX liquidity.
We recommend you swap only aUSDC --> aUSDC on Testnet.
aUSDC is the Axelar bridged version of USDC on testnet. A transfer of aUSDC --> aUSDC across chains has no swaps needed, so you can rely on a 1:1 exchange rate.
