Totalis, a prediction market derivatives platform, has officially launched, allowing users to place parlay bets across various event markets. The platform is also expanding into structured products, offering new opportunities for users. Totalis completed a $500,000 seed funding round in April, with Y Combinator as a key investor. Notably, this marks the first instance of Y Combinator investing entirely in USDC, with the transaction settled on the Solana network and funds held by Ramp.
