Ultra (UOS) was launched in 2017 and is a blockchain-based PC gaming entertainment platform that provides new opportunities to game developers, players, and influencers. Ultra was developed as a fork of EOS, a blockchain developed by block.one - a private company incubating, acquiring and investing in technologies and businesses. As a fork of EOS, Ultra has been issued as an ERC-20 token running on the Ethereum blockchain.

All purchases of games, virtual items and services on Ultra Games use smart contracts which require Ultra Coins (UOS tokens). Furthermore, all features on Ultra such as the loyalty program, bug testing, beta testing, trade of digital goods, advertisements etc., only work with UOS tokens.

Ultra believes in empowering game developers and publishers by giving 5% of all sales profits to an annual "game developer and acquisition war chest." The money in the fund is locked for 2 years and can only be used for acquiring games. The total supply of UOS is 1 billion.

As Coinmetro uses smart contracts for Ethereum and ERC-20 token deposits, the amount of gas required is slightly higher than a typical transfer. To be sure that your transaction is successful, please set the transaction gas limit to 55,000. The fee difference is minimal. If your gas limit is too low, the transaction will simply be rejected by the Ethereum network. There is no risk of loss of assets caused by a too-low gas limit.

If you're depositing from another exchange, it is important to ensure they support sending funds to ETH contracts or using a full ETH wallet as an intermediary.

Important Note - To request a withdrawal, your account profile needs to be verified as well as having the funds to cover your withdrawal. The first time a withdrawal is made to a destination, the destination needs to be confirmed via e-mail. If you have 2-Factor Authentication enabled for withdrawals, you will be asked to input the code for each withdrawal, approved or not. We suggest enabling 2-Factor Authentication to protect your account.

Withdrawals waiting for approval can be cancelled and the withdrawal status can be found by selecting the Wallet on your Coinmetro Dashboard. Please note that already-approved withdrawals cannot be canceled. If there is no Cancel button visible, this unfortunately means the withdrawal can no longer be canceled, and you will find a transaction ID (TXID) instead. This is a link to the relevant transaction hash on a Blockchain Explorer website where the status can be checked further.
