Fintechs building crypto products with privacy lack a system that's:
- Composable – lets them integrate with any DeFi protocol.
- Easy – lets them ship new features quickly.
- Fast – lets them make smooth UIs.
The root cause: privacy isn't native to blockchains. To get it today, fintechs have to build their own custom solutions. But these solutions often don't interoperate, are difficult to make, and require extra network calls.
Seismic Reth is a blockchain execution client with native privacy. It's complete with private storage, encrypted transactions, and TEE integration. Today, we're open-sourcing the code.

This wouldn't have been possible without the incredible work of the Reth team. Seismic Reth is a fork of Reth – surprise! Our implementation can be found here.
