Privacy layer

Your trade reaches Polymarket. Nothing else does.

Every standard request to Polymarket carries your IP address, device fingerprint, and country. The CLOB, the relayer, and the data API all receive this by default. Your wallet is pseudonymous — your connection is not.

Shard's Privacy Layer intercepts all traffic before it reaches Polymarket and routes it through two dedicated layers.

Architecture

Layer	Role
Shard Edge Layer	Handles all public reads — fully anonymous, no wallet exposure
Shard Privacy Router	Routes authenticated reads and signed writes through the Header Anonymiser
Header Anonymiser	Strips IP, headers, and device fingerprint from every request

---

Three Components

① Public Mirror

Edge Layer — Public reads · No wallet

Prices, books, and public market data are served from Shard's edge cache. Your IP never touches Polymarket when browsing.

② Identity Cloak

Privacy Router — Authenticated reads

Positions, balance, and history are loaded through Shard's IP. Polymarket sees a request — not you. Your wallet is visible to the protocol, you are not.

③ Stealth Relay

Privacy Router — Signed writes · Neutral region

Every signed order passes through the Header Anonymiser before reaching Polymarket. IP stripped. Headers stripped. Device stripped. Operates from a neutral region — your country and network never leave you.

Traffic Routing

Action	Route	What Polymarket receives
Browsing markets	Public Mirror	Nothing — fully cached
Reading portfolio data	Identity Cloak	Shard's IP only
Placing orders	Stealth Relay	Clean signed order only

Read traffic : public data from the Mirror, wallet-scoped data via the Identity Cloak. No IP-tied identity ever reaches Polymarket.

Signed writes : trades egress through the Stealth Relay after the Header Anonymiser drops your IP, headers, and device. Country and network never leave you.

Shard's Privacy Layer is active by default for all users no configuration required.
