For those unfamiliar with miner contracts, a brief explanation: You pay funds, which are then added to a large pool. Every day, you can claim part of the pool of funds based on your share of the pool. When the contract's balance reaches 0, the mine runs "dry", meaning it doesn't pay any more rewards until new funds get deposited. Traditional miners operate like a pure Ponzi scheme. Especially in 2020/21, you saw hundreds, if not thousands miners launching (especially on the BNB chain) just to run dry after weeks or months. Investors who joined those miner contracts last didn't even get their initial out. If you know the URM community, then you know that we don't blindly fork other contracts, but build them from the ground up with our own twist. Our miner contracts are no exception... While all other miner contracts let their balance sit in the pool, we let our funds generate yield on Peapods Finance (). The miner contract deposits Hestia and URM into peapods and receives pHestia and pCircle in return. Those "pods" are part of the Peapods system that captures yield from on-chain volatility. When Hestia or URM becomes more volatile, the miner earns more, and that extra yield increases the overall miner contract balance. In essence, price movement becomes fuel for the mine. Especially for URM, this means the potential for exceptional yield, since our entire ecosystem is built to create more and more volume! By generating external yield, we believe that the URM miner contracts can run indefinitely, never running dry. ### How "mining" works The Miners operate through a simple concept. When you deposit Hestia or URM into the smart contract, you use those tokens to hire virtual “miners.” These miners start generating yield for you in the form of new URM or Hestia, continuously, second by second. Your initial deposit is permanently locked, meaning you can’t withdraw it later. However, the rewards generated from that deposit are yours to manage however you want. Once your miners are active, you have two options. You can either compound your rewards to hire more miners and grow faster, or you can sell your earned rewards to take profits. Selling is limited to a percentage of the contract’s balance per transaction, and each withdrawal includes a 5% tax. On top of that, there is a miner penalty based on the size of your sale. For example, selling at the current sell limit of 1,114 tokens triggers a 1% penalty. Selling half that amount results in a 0.5% penalty. This creates an interesting dynamic: users are encouraged to sell smaller amounts more frequently to reduce fees, which smooths out selling pressure over time. URM and Hestia miner contracts work identically, with the exception that URM has an auto-compound feature. The URM contract is called the Temple, while Hestia is called the Mine. For everyone who is overwhelmed by all the information on the mine website, one of our core community members created a simplified website for the mines and Rage: . You can just enter the amount you want to deposit and start mining!
{% hint style="info" %} **Important Information!** **Even though the URM community tried to create a more advanced Miner contract, it is still a miner contract! Which means if the balance hits 0 and the mine runs dry, no more rewards will be paid out. Always keep that in mind when you invest!** {% endhint %}
