Privacy projectSeismic: Encrypted EVM L1 (pre-mainnet). Technology: trusted execution environments (TEEs).
Seismic raised seventeen million dollars from a16z to build an encrypted EVM where confidentiality is a language-level primitive. Shielded types such as suint256 mean a developer marks a variable private and the chain takes care of the rest, which is about as low-friction as confidential smart contracts have ever been made. Two fintech partners are already building on it. The chain runs on Intel TDX, a platform researchers have continued to probe successfully on fully patched hardware, and mainnet, once eyed for the end of 2025, has not yet been re-dated.

What is trusted execution environment?
Computation runs inside an isolated hardware enclave whose contents the host operating system cannot read, under a hardware-trust assumption.
How it compares with the other approaches on latency, trust assumptions and fit is set out, with sources, in the technology taxonomy.
