Staking AVAX provides roughly 9% return on delegated tokens. To learn more about doing so, please read the following guide.
Step 1 — Open the Avalanche Wallet
Access the wallet using a key phrase, Keystore file, or Ledger device.
Step 2 — Navigate to the "Earn" section
Note: the minimum that can be staked is 25 AVAX.
Enter the amount you wish to transfer to your P-Chain and complete the transfer by clicking the "Transfer" button below.
Step 3: Add a Delegator
Next, add a validator to delegate the tokens to.
Specify the staking period and stake amount. Pay attention to the end time of the selected validator. The delegation period cannot be set to end past the end date that the validator has set.
Confirm the details.
Congratulations. You are now delegating the Avalanche Primary Network!
Why was 25 AVAX chosen and will that change?
25 AVAX is baked into the genesis block, as a network parameter. Changing it would require a network upgrade. AvaLabs plan has been to make network parameters themselves decided by consensus (e.g. voting), but that code hasn't been written yet.
The lower limit is an anti-Sybil mechanism. If it wasn't there I could create a billion 0.000000001 AVAX delegations, which would not be good for network health.
