Perfectly understandable. I step away for a month or two and then everything has changed, and I have to learn it again too.

You can skip the Metamask path from that older video. If the Metamask site is tripping your virus scanner, leave Metamask out of it. Hive Keychain v4.1 is the same Keychain you already use, and it is now Hive and EVM in one wallet. Swap, bridge, buy, and sell are in the portfolio, so that part stays inside Keychain.

DEC to SPS is still the in-game step. After that, use Keychain for the move and the swap. What you swap into does matter. Use something your exchange will actually take as a deposit, usually USDC, then send that to the exchange and sell it. A random token in the middle is just another step.

That cash-out is a normal payment through the wallet you already know.
