Deposit wallet

Read the relayer nonce (and GSN relay) for an imported Polymarket wallet

The imported-wallet analogue of the deposit-wallet nonce endpoint: returns the relayer nonce and, for a legacy ProxyWallet (sig_type: proxy), the GSN relay address needed to construct the digest the browser signs. For a Gnosis Safe (sig_type: safe) relay is always null. Fetched server-side purely because Polymarket's relayer is CORS-blocked from browsers. The response is public information; the ownership check is belt-and-braces, not a secrecy boundary.

Error shape. Most 4xx/5xx here have an empty text/plain body; the 502 cases carry a plain-text reason (relay-payload fetch failed: … / nonce fetch failed: …). Scope and identity failures return the structured envelope. Auth & scope. Requires trade:execute for polymarket and identity + wallet ownership. No mutation gate, so a bare session JWT reaches it.
