# Stake Assets
# Introduction
Staking is the feature based on smart contract technology developed by Neutrino team. It is similar to conventional banking where you can deposit or withdraw assets. Waves.Exchange supports staking Neutrino tokens.
The profitability of staking Neutrino is about 20% yearly (this value is calculated in realtime and may change every day). You can check current profitability on the Staking Dashboard.
Currently staking works only with Neutrino assets, so to deposit the assets for staking, you have to buy Neutrino assets first.
Neutrino (or USDN) is the unique innovative algorithmic stable coin, so the exchange rate is usually about $1 with small deviations. Staking other types of assets will be supported later.
How Neutrino staking works:
The percentage of profit is not regulated by third party and is higher than any bank currently offers.
You receive your interest payments in USDN daily.
You can check the correctness of payments at any time and cancel your staking if something does not suit you. You will not lose interest you have already accrued.
You do not send your funds under someone's management. The assets are always under your control, all operations are carried out through an independent public smart contract. Each transaction is transparent and public (your personal data is safe).
The smart contract will never ask you for any documents. Your staking balance and payouts are completely anonymous.
