web3 Professional Firm DeFimans Forms Partnership with Decentralized RWA Perpetual DEX "Ostium" for Japan Expansion

DeFimans Inc. (Location: Minato-ku, Tokyo; Representative Directors: Nobuyoshi Ono, Taishi Sato; hereinafter "DeFimans") is pleased to announce that it has formed a partnership with "Ostium" (hereinafter "Ostium"), a decentralized perpetual DEX that utilizes Real World Asset (RWA) price data.

Through this partnership, DeFimans will organize insights into international trends and market structures in the RWA domain and on-chain derivatives market, providing analytical insights into market acceptance and institutional considerations in the Japanese market.

This initiative is not intended to promote specific trading activities or usage, but rather aims to establish a system that ensures accurate and objective information distribution to web3 users and relevant parties.

■ What is Ostium?

Ostium is a decentralized exchange that brings price data of Real World Assets (RWA) such as gold, crude oil, stock indices, and foreign exchange on-chain, offering perpetual (unlimited futures) trading based on their price movements.
Users can directly trade "profits and losses due to price fluctuations" without actually holding the assets, thereby realizing an accessible market without going through traditional securities companies or exchanges.

Expansion and Reality in the Japanese Market

A distinctive feature of Ostium is that its spontaneous adoption by individual traders has progressed even before the implementation of marketing strategies for the Japanese market. Driven by demand for on-chain trading targeting RWAs such as gold, crude oil, and foreign exchange, Japanese users have naturally flowed in, and Japan has now become one of its main markets.

Japanese users account for approximately 20-25% of daily trading volume, with cumulative trading volume exceeding $4 billion over the past 30 days. Among these, gold alone accounts for approximately $1.17 billion and 30,000 transactions.

Project Background

Ostium has raised a total of $20 million in its Series A round, with development and deployment progressing under the support of global investors such as Coinbase Ventures as the lead investor, General Catalyst, and Jump Crypto.

Trading Services

Ostium offers perpetual trading based on the following Real World Assets (RWA):

• Gold

• Crude Oil

• Silver

• Foreign Exchange (FX)

• Global Stock Indices

All of these are provided on-chain, and transparent execution based on index prices is achieved through oracle-based price referencing. Furthermore, rollover fees are fixed, ensuring high predictability of position holding costs.

Features of Ostium

• Access to RWA Prices: Trade price fluctuations of real-world assets on-chain

• Perpetual Trading: Ability to hold positions without an expiry date

• On-chain Execution: Automated execution via smart contracts, no intermediaries required

• Self-custody: Users manage their own assets

• Market-linked Trading Hours:

  • FX Pairs: 24 hours/5 days a week

  • Commodities: 23 hours/5 days a week

  • Stocks/Indices: Aligned with spot market trading hours
    *Linked to trading hours of underlying global markets

This provides "global and seamless asset access" independent of traditional financial infrastructure.

■ Potential of the RWA Perpetual Market

Traditionally, investing in real-world assets has been confined to a limited number of players due to numerous restrictions, such as opening accounts through securities companies or brokers, trading hour limitations, and country-specific regulations.

On the other hand, with advancements in blockchain technology, a model has emerged where real-world assets are traded on-chain not as the assets themselves, but as derivatives (perpetuals) linked to their prices.
This mechanism is similar to Contracts for Difference (CFD), allowing users to gain exposure to price fluctuations without holding the underlying asset.

This approach is enabling the following characteristics:

• Expanded Accessibility: A wider range of users can participate in the market (subject to regional regulations)

• On-chain Settlement: Fast and transparent settlement via smart contracts

• Reduced Intermediation Costs: Lower reliance on centralized intermediaries

• Connection to Global Liquidity: Access to diverse asset prices on a single infrastructure

Furthermore, trading hours depend on the protocol design, with some models allowing 24-hour trading. Ostium, however, emphasizes price formation that closely mirrors real markets, with prices and trading linked to the underlying global markets.

The convergence of RWA and DeFi is attracting attention as an area with the potential to redefine traditional financial access. Ostium aims to build a new trading infrastructure at its core, providing on-chain access to real-world asset prices.
