Summary: Trail of Bits published a post by Paul Bottinelli on September 25, 2026, arguing that combining threshold signature schemes with trusted execution environments can strengthen MPC deployments. The post's stated position is that the TEE should be treated as a defense-in-depth layer rather than a substitute for a sound protocol.

Bottom line: The guidance targets teams layering TEEs onto threshold-signature MPC: the TEE is framed as an added layer, not a replacement for a sound protocol, so a deployment that leans on the enclave alone is relying on the wrong control.
