Stake APT
**Step 1: Acquire APT**
Staking APT via Amnis requires you to have APT. For example, you may purchase APT on centralized exchanges like [Coinbase](https://www.coinbase.com/) or [Binance](https://binance.com) from fiat currency.
Once purchased, withdraw the APT to your Aptos-supported wallet. ([Coinbase](https://help.coinbase.com/en/coinbase/trading-and-funding/cryptocurrency-trading-pairs/how-to-send-and-receive-cryptocurrency), [Binance](https://www.binance.com/en/support/faq/115003670492))
**Step 2: Connect wallet to Amnis Finance**

On the [Stake ](https://stake.amnis.finance/mint)tab, click "Connect Wallet".
