The next step beyond private RPCs — protection without trusting a single builder.
Private RPCs hide your transaction by sending it to one builder you trust. An encrypted mempool keeps the shared, decentralized mempool — but encrypts each transaction so no one (not even the builder) can read it until after it’s committed to a block. That removes the information bots need to front-run, without centralizing order flow.
The leading encrypted-mempool project: threshold encryption, live on Gnosis Chain and coming to Ethereum PBS.
A complementary private RPC today, also moving sensitive infra into TEEs.
Encrypted mempools aim to give you front-running protection and decentralization at once — Shutter is the project to watch.
