Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

TIMELOCK: 10 to 20% of every transaction will be kept in a smart contract for 60 days. In addition, 5% of Ultra profits will be reserved for 2 years to fund exclusive games that use its blockchain and NFTs capabilities. ENGAGEMENT: Tokens are earned by performing specific actions such as; helping developers to build better games; watching ads; beta testing; answering surveys, and more. STACKING: Players can get rewarded with free games, swag and exclusive content just by holding tokens. SPENDABILITY: Users can buy and sell games/items for UOS, and in hundreds of shops through partners.
