# What is Polaris? | Decentralized Altcoin Options Exchange We built [Polaris](https://polaris.trade/) to keep all trader's assets safe throughout the trading cycle - transparently, securely, and in a decentralized manner. Polaris is a rebrand of PowerDEX. Here’s how it works: * Your assets are stored in a segregated wallet created by you on the blockchain. * Your funds are kept separate from others and visible on-chain at all times. * We utilize [Multi Signature wallet technology](/polaris/what-is-powerdex/powerdex-multi-signature-wallet.md) (Multi-Sig) from the open-source community. Multi-Sigs are a well-understood and reliable way to keep your digital assets safe. #### What does a trading session on Polaris look like? * Anonymous Sign-Up: Sign up without an email or phone number using Ethereum's standard Authentication ["Sign In with Ethereum"](https://login.xyz/) * Create a Multi-Sig Wallet: After your first sign-up, set up your Multi-Sig Wallet. This is where your funds will be stored. * Deposit Funds: Send ETH or ERC20 tokens to your Multi-Sig and they will be made available for trading on Polaris instantly. * First Class trading experience: You can now use all of Polaris' tools: REST and FIX API trading, RFQ, high-frequency trading, no blockchain fees, the largest altcoin option selection in the industry, and more. * Easy Settlement: Done Trading? Settle your balances on-chain with one click. Worried about gas fees? Settlement fees are on us. * Withdraw Anytime: You can take out your money whenever you wish. The funds will come directly from your multi-sig, so make sure you have settled your balances beforehand. As a beta phase bonus, withdrawal fees are also on us! We built Polaris to give you the best of both worlds: CEX ease and DEX freedom. For more details on Polaris, check out the FAQ.
