I am trying to stake my Ampleforth using Geyser using the following link
https://www.ampleforth.org/geyser/oldfaithfulV1-balancer-ampl-usdc
As you can see below, I do have some AMPL in my Ethereum wallet but once I integrate with MetaMask, the page says I have 0 balance even though my MetaMask shows I have some AMPL tokens.
What am I doing wrong?
You have no ETH to pay the gas/tx fees. You need ETH to pay for the TX fee. Then type the amount of AMPL in the box on the website and click the deposit button. The tx fees will probably be high though, so it's reallly not worth it imo.
