Platforms for decentralised finance Individual users will be able to serve as insurers for SpaceX flights thanks to a new DeFi derivative product introduced by Uma and Opium Network. The financial instrument can be used to mitigate financial risks associated with SpaceX's launch, as well as produce some revenue. It's not entirely clear who the new instrument's intended audience is. As it stands, SpaceX only provides payload insurance for about 5% of their value.
