Deposit wallet
Deploy the caller's Polymarket deposit wallet and set its trading approvals
Creates the user’s deposit wallet — a per-user ERC-1967 proxy on Polygon, deployed through Polymarket’s relayer at a deterministic CREATE2 address derived from the owner EOA. Two relayer operations run: the deployment, then a signed batch setting the CTF/collateral approvals the venue needs.
Idempotent on the deployment leg. Re-submitting for an already-deployed owner is treated as a no-op success and comes back with deploy_tx_id: null.
It does not move user funds — it deploys a contract and grants approvals. The approval batch is signed server-side under the user’s delegated key; the batch deadline window is one hour, and each relayer transaction is waited on for up to 120 s.
A successful response means the submitted approval batch has confirmed. batch_tx_id is empty when no batch was submitted.
Auth & scope. Requires trade:execute for polymarket, identity ownership, and the mutation gate.

}Authorizations
Credential client id (kairos_ck_...). Must be sent together with X-Api-Key and X-Api-Secret.
64-char hex API key.
64-char hex API secret.
Body
application/json
The common identity body shared by the deposit-wallet endpoints. All three fields are checked against the authenticated caller and can only ever CONFIRM authority, never grant it — omitting them is not an option here, but supplying someone else's is a 403.
Response
Wallet deployed (or already present) and approvals submitted.
Response for POST /exchanges/polymarket/deposit-wallet/onboard.
The deterministic (CREATE2) ERC-1967 proxy address for this owner.
Relayer transaction id for the confirmed trading-approval batch. Empty when no batch was submitted (approvals already present or optional approvals skipped).
Relayer transaction id for the proxy deployment. null when the wallet was already deployed — the relayer is idempotent and that case is treated as success.
