Even during yesterday’s crash I was able to execute trades at reasonable gas prices (<$1).
I’ve developed a couple of dapps that run on polygon, and while the docs could use some love the overall experience was pretty frictionless.
Crypto.com now supports deposit/withdraw directly to polygon making it possible to skip ETH altogether.
For bridging I recommend Relay if you are setting up on a new chain for the first time, then xpollinate for later transfers of just stables. Fees are super low to go from L2 to L2 these days.
Rabby is a really nice web wallet the replaces metamask and supports all the L2 chains by default, built by the guys at debank.
