TurboFlow, an onchain trading platform offering prediction markets and perpetual futures, has raised $6 million in a seed funding round. Pantera Capital led the round, with Susquehanna Crypto and Digital Currency Group participating, TurboFlow said Monday. Those are the only three investors in the round, which closed in March after fundraising began earlier this year, founder Tony He, former co-founder and partner at Amber Group, told The Block. The round was structured as a simple agreement for future equity (SAFE) with token warrants, He said, declining to disclose valuation.
