-## Hosted-trading venues
-
-The venues below support **hosted trading** end-to-end (build → sign → submit → settle) without running a local PMXT service. All hosted trading is custodied in a single Polygon-based `PreFundedEscrow` — you fund USDC once on Polygon, regardless of which venue's chain the trade actually executes on.
-
-| Venue | Execution chain | Settlement chain | Notes |
-| ----- | --------------- | ---------------- | ----- |
-| Polymarket | Polygon (chainId 137) | Polygon (same-chain) | USDC.e via Polymarket CTF exchange. |
-| Opinion | BSC (chainId 56) | Polygon → BSC (cross-chain) | PMXT relays an internal cross-chain settlement leg; you fund + sign on Polygon only. |
-
-EIP-712 order signatures always target the Polygon `PreFundedEscrow` domain (`chainId: 137`) — your wallet never has to switch networks, and any EVM-compatible private key works.
-
-Venues not in this table are **read-only** via the catalog; for write methods (`createOrder`, `cancelOrder`, etc.) on those venues, use [self-hosted mode](/guides/self-hosted).
