APY rates

APY rates are flexible, and can change depending on the market conditions. You can see current rates for yBTC on this website, but we also publish APY rates on blockchain, so you can further verify on explorer. We always aim to provide better APY rates and thus can switch between different trusted service providers to ensure best yields.

Interest amounts are distributed daily according to your yBTC balances at the time of snapshot. If you transfer yBTC to a different address, this new address will start receiving rewards instead of your account.

Getting started with yBTC

You’ll need a Stellar wallet to store yBTC and receive daily rewards. Any Stellar wallet would work as long as it allows you to add trustlines. We recommend LOBSTR for mobile devices, StellarX for desktop. It’s always a good idea to use a hardware wallet such as Ledger or Trezor, especially if you plan to store significant amounts.

Most centralized exchanges (e.g. Coinbase or Binance) do not allow you to add Stellar tokens yet, so you should get a non-custodial wallet such as LOBSTR. Use the button below to add a trustline to yBTC or search for yBTC or ultrastellar.com in the asset list.

Converting between yBTC and BTC

Ultra Stellar provides anchoring service that enables 1:1 conversion between yBTC and BTC. Follow the instructions on this website, the whole process only takes a few minutes.

Several Stellar products (LOBSTR, StellarX, StellarTerm) support interaction with anchors, so look out for Deposit and Withdraw buttons next to yBTC asset. This way you can make the conversion without leaving your wallet.
Alternatively, you can trade yBTC on SDEX as any other asset. Keep in mind that the price of yBTC on the Stellar DEX is a market price, which may not always be equal to 1 BTC.

Get interest payouts
Once you have yBTC in your wallet, you are all set. Within 24 hours you will get an interest reward, and you’ll be receiving those daily. Interest payout APY rate is stated in the transaction memo, so you can always check the current APY rates.
Received yBTC interest can be converted into BTC or other tokens. If your yBTC position is changed, your next interest payouts will be adjusted accordingly.

Commonly asked questions.
How often is interest paid?
The interest is paid daily. The amount is based on the current APY rates and the number of yBTC in your account at the time. The interest is compounding, meaning that earned yBTC will also generate additional yield.
How is the revenue generated?
Ultra Stellar acts as an asset manager and works with multiple trusted CeFi/DeFi protocols to generate yield on the funds in custody. A thorough due diligence process takes place before a decision is made to utilise a specific platform. This is an ongoing process, and Ultra Stellar will continue to monitor platforms providing high APY. However, we only work with companies/protocols with over $1B of AUM and having a clear history of at least a year of production operations.
Further on, we will continue to investigate other options for revenue generation, including providing loans. Any changes to the model of revenue generation will be communicated in advance on our social media channels and on the website.
What are the risks?
Cryptocurrency assets are subject to high market risks and volatility. Please refer to this page explaining the risks of holding yield generating tokens issued by Ultra Stellar such as yBTC.
Can I get better APY rates with yBTC than other CeFi/DeFi providers?
Sure, we partner with multiple providers, and are always evaluating the market conditions.
Even though Ultra Stellar takes a small fee for management of the funds, there's a chance that yBTC will provide better returns and higher effective APY than using the same CeFi/DeFi provider directly. The additional savings are possible because we can often reduce fees (network, deposit, withdraw) when operating with larger amounts.
Is there a way to increase payouts?
Not yet. Stay tuned for further updates! hint: $AQUA
