Arcus, a decentralized exchange developed in collaboration between the dYdX team and Robinhood Crypto, has launched its pToken protocol on Robinhood Chain. The protocol converts perpetual futures position accounts into ERC-20 tokens, allowing traders to gain leveraged exposure by trading these tokens like spot assets without directly managing margin requirements.
Each pToken represents a pro-rata share of a pre-configured perpetuals account tied to one market and one leverage level. Initial markets include Bitcoin (BTC), Solana (SOL), Hyperliquid (HYPE) and selected Robinhood Stock Tokens. Although the format changes, the underlying risk remains: price moves, funding payments, margin requirements and liquidation rules still affect the account behind the token.
Arcus also announced multi-asset collateral for selected Robinhood Stock Tokens, including SPY, QQQ and MAG7. Eligible traders can borrow the stablecoin USDG against these tokenized equities and use it as margin for futures trading, avoiding the need to sell their stock tokens first. Arcus distinguishes this collateral utility from pTokens: collateral changes what assets can be deposited to support a position, while pTokens change how an existing leveraged account is held and transferred.
The long-term usefulness of pTokens will depend on pricing, liquidity and independent DeFi integrations. A Bitcoin pToken provides exposure to an Arcus Bitcoin perpetual account, not spot BTC ownership. DeFi protocols considering pTokens as collateral must account for embedded leverage, liquidation conditions and reliable pricing. Arcus uses a hybrid exchange design with offchain order matching and onchain settlement safeguards, making transparency around redemption and liquidation critical for adoption.
