Arcus

Arcus is a decentralized exchange (DEX) that facilitates 24/7 trading of stock tokens and perpetual contracts, leveraging the Robinhood Chain.

Launched in 2026 by the team behind dYdX and in partnership with Robinhood, Arcus enables users to trade a diverse array of tokenized stocks, indices, commodities, and cryptoassets with zero trading fees and up to 50x leverage.

The platform is particularly notable for transforming perpetual futures positions into transferable ERC-20 tokens, allowing users to manage their exposure and collateralize trades without selling their existing holdings^[1]. ^[2]​

History

Arcus emerged as an innovative player in the decentralized finance (DeFi) landscape in 2026, spearheaded by a team renowned for their work on the dYdX protocol.

The platform was developed in line with a strategic partnership with Robinhood, which not only provides significant financial backing but also supports Arcus with its blockchain infrastructure — the Robinhood Chain​^[3]. ^[4]​

The launch of Arcus significantly coincides with an era when traditional financial systems have been increasingly transitioning toward integration with blockchain technology.

Since implementing its exchange mechanisms, Arcus has introduced new investment strategies aimed at the blockchain domain, much akin to the way traditional markets have evolved over decades with sophisticated financial products. ^[4]​

Platform Design and Features

Arcus is uniquely positioned as a DEX that does not impose trading fees on stock token transactions and offers seamless, instantaneous deposits. It supports a self-custodial approach and leverages the Robinhood Chain for blockchain execution of trades.

The platform caters to both retail and institutional traders by providing deep liquidity sourced from Robinhood and other top institutional market-makers^[3]. ^[5]​

Arcus's product offerings include perpetual futures and stock token trading across over 95 markets. Users gain access to a range of financial instruments — from equities and indices to cryptocurrencies and commodities.

The perpetual futures on Arcus are notable because they convert these positions into ERC-20 tokens, offering traders greater flexibility and control over their investments^[3]. ^[4]​

The platform's API is designed for speed and clarity, facilitating high-frequency trading with features like order management and market data feeds available through a single unified interface. This technical capability is bolstered by a fast confirmation time and a high throughput of orders per second. ^[3]​

Technology and Architecture

Arcus integrates decentralized finance principles with high-stakes trading capabilities, anchored by its infrastructure on the Robinhood Chain. This partnership ensures high performance and reliable execution necessary for large volumes of transactions across various kinds of assets, including tokenized stocks and cryptocurrency derivatives^[1]. ^[6]​

The introduction of transferable ERC-20 tokens for perpetual positions signifies a noteworthy technological advance, enabling users to leverage their existing stock token holdings without selling them.

Additionally, tokens like pBTC3x and pHOOD3x provide leveraged exposure to Bitcoin and the HOOD stock token, showcasing Arcus's capacity for implementing complex financial strategies on the blockchain. ^[1]​

Funding and Investors

Arcus is chiefly backed by Robinhood, an influential entity in the fintech space. This backing not only signifies a strong financial foundation but also represents strategic alignment in technological advancement and market reach. This partnership affords Arcus access to high-quality infrastructure and liquidity, integral to its operations and growth plans^{. [2]}​^[3]​

Such strong financial and strategic backing enables Arcus to operate without charging trading fees, which can be a significant barrier for many traders. This aligns with their mission to democratize access to financial opportunities by reducing barriers for both small and large-scale traders. ^[5]​

Usage and Adoption

Arcus supports the trading of a diverse range of assets, making it accessible to a wide user base from different trading backgrounds. Accessible via web and promising mobile integration soon, the platform aims to expand its accessibility further with mobile trading options and on-ramps such as Apple and Google Pay. ^[3]​

The platform's ability to seamlessly trade across various assets and markets places it in a strong position to attract both traditional finance traders and cryptocurrency enthusiasts looking to venture into tokenized asset trading. As market demands evolve, Arcus is poised to expand its offerings and continually refine its trading experience. ^[5]​
