Matemask can't send KLAY coin

After setup Network (Cypress) in Metamask, I can’t send KLAY coin (only KLAY coin, the tokens of klaytn chain can be sent easily)…please see picture

This is Network setup

Thanks for filing an issue in KlaytnForum.

It seems that the endpoint node (api.cypress.ozys.net) rejects your request as the error indicates (request limit exceeded).

Please check out the “New RPC URL” fields and fill it in with the right value.

Thanks.

Also, you can find a hint how to connect Metamask with Klaytn via KAS in the below answer:

i change my RPC from PC to MOBILE URL like the medium link provides (KLAYswap & MetaMask: More ways to access KLAYswap! | by KLAYswap | KLAYswap | Jul, 2021 | Medium) besides im using metamask on PC but the RPC URL worked was the Mobile, you just need to change the api to kaikas in your chain configs (SEND SMALL VALUE TO TEST) and it will work. I send it right now to my binance account.
PLEASE PUT THIS ON HIGHLIGHTS BECAUSE I HAD A BAD TIME TRYING IT. (KLAY BINANCE > METAMASK > BINANCE)

GAS PRICE (GWEI) = 23
GAS LIMIT = 21000

maybe the chain sees metamask extension as mobile.i dont know, but worked.
