You can stake Glimmer tokens via the official dApp developed by the Moonbeam Foundation. Here are the steps to do this: 1. Create an account with MetaMask if you don’t already have an existing one. 2. Head to this link here http://apps.moonbeam.network/moonbeam and connect your MetaMask wallet to the Moonbeam network dApp. Ensure that you switch the network on MetaMask to Moonbeam while linking. 3. Click on Manage delegations within the Staking tab on the application. 4. Select a collator you wish to delegate your GLMR tokens for staking to, enter the number of tokens you wish to stake and click on Delegate to confirm the transaction. 5. A few minutes after the transaction is confirmed, the staked GLMR tokens will be deducted from your balance in MetaMask.
