Arcus has launched the pToken protocol on Robinhood Chain, tokenizing shares of perpetual contract accounts with fixed market and leverage levels into transferable ERC-20 tokens. The tokens can be used in on-chain lending and other protocols. The first supported exposures include BTC, SOL, HYPE, and select stock tokens. Arcus also introduced multi-asset collateral, allowing SPY, QQQ, and MAG7 tokens to be used as collateral for perpetual trading.
