Official Polyester SDKs share the same ConnectRPC + WebSocket Protobuf product surface for API-key trading bots and backend integrations. Use this matrix to compare languages before you pick an SDK.

means the
capability is available on the public client for that language. means it is
intentionally out of scope for that SDK (not an unfinished stub).

Language notes
- TypeScript also supports browser wallet login and MFA. Use it for full-stack and browser apps; Python, Go, and Rust are API-key SDKs.
- Python offers async and sync clients. WebSocket streams are included in the base install; the
[realtime]extra is no longer needed and adds nothing. - Go is synchronous. Client aliases such as
Candles,Accounts, andTradingWithdrawsmatch the Python naming style. - Rust is async (Tokio). Realtime is always compiled in; the
realtimefeature is kept only so existingCargo.tomlentries still build. Prefermarket_data,resolve, andwithdraw(noCandles/Accounts/TradingWithdrawsaliases).
Intentionally out of scope (API-key SDKs)
Python, Go, and Rust do not wrap:
- MFA enrollment and challenge APIs
- Wallet login (
CreateWalletChallenge,LoginWithWallet)
Those flows belong in browser / session clients. Subaccount MFA requirements (policy flags) are still available on the API-key SDKs.
