What are Real World Assets?

Real World Assets, or RWAs, are a catch-all term used in DeFi to refer to the universe of tradable assets not native to the blockchain – things like commodities, indices, real estate, foreign exchange pairs, and more.

As DeFi matures, blockchains increasingly support both tokenization of and synthetic price exposure to these Real World Assets.

Why do you need a purpose built DEX for Real World Assets?

RWAs have unique properties that require a unique onchain solution to support them. Unlike crypto-native assets, for instance, reference markets for most RWAs experience closures during daily market settlement, weekends, and holidays. A secure, purpose-built DEX design ensures both traders and Liquidity Providers are protected against things like erroneous price reports during out-of-market hours, front-running during market reopen, and more.

Can I redeem my positions for the underlying asset?

No. Unlike tokenized or wrapped Real World Assets, whose grounding to the underlying asset's price is ensured through redeemability, Ostium facilitates synthetic, or virtual, price exposure to the asset, mediated through DEX fee structure – without claim on the underlying.

Just as perps on BTC facilitate leveraged price exposure to BTC without perp ownership implying a claim on BTC itself (simply indirect exposure to its price), so do Ostium's RWA perps facilitate leveraged price exposure to RWAs without claim on the underlying RWA itself.

What collateral does Ostium accept?

At launch, Ostium will only support native USDC on Arbitrum (not wrapped USDC). This applies both to traders and liquidity providers, meaning both parties will be able to deposit and redeem exclusively in USDC. Future iterations and feature additions will work to support a wider variety of collateral assets.

What do I need to begin trading?

1. Wallet: if you have a wallet already, connect it to Ostium. If you don't,  create a new wallet through our partners' social login infrastructure (prompt after Connect Wallet) or download a wallet extension like Metamask or Phantom.

2. Funds: you'll need native USDC on Arbitrum. You can: A) Bridge from other chains (make sure to select native, not bridged "USDC.e"!), B) send to your wallet address from a Centralized Exchange (CEX), or C) use one of the simple fiat on-ramps through your wallet provider directly into your wallet (e.g. Transak on Metamask, Moonpay on Phantom).

Do I control my assets?

Yes! Our DEX is self-custodial, meaning you always control your own assets. Unlike on Centralized Exchanges, no one but you can touch your funds.
