The handling of precious assets that can hold significant value should be treated as such. When building Sphere, we chose to focus on four core pillars: design, user experience, gas efficiency and, crucially, security.
When you interact with Sphere, you're interacting with the Seaport Protocol. Trust and security are paramount in web3, and we take that seriously. The Seaport Protocol has been audited repeatedly and is currently on top in the industry. It allows for customization, but optimizes security. As the creators of the protocol, trusting OpenSea means trusting the smart contracts that Sphere uses.
