# Wallet and network

Quick answers for connecting wallets and choosing networks safely.

## Which wallet should I use?

Use a **supported Solana wallet** that you trust (Phantom, Solflare, etc.). QuantDesk does **not** custody keys — you remain responsible for seed phrase security.

## Devnet vs mainnet

* **Devnet** — default for local setup and experimentation; use faucets for SOL; expect resets and instability.
* **Mainnet** — real funds and real risk; verify URLs and program IDs every session.

## I connected but nothing loads

1. Confirm backend + frontend are running (see [Start in 5 minutes](../getting-started/start-trading-in-5-minutes)).
2. Hit API health: `curl $QD_API/health` when developing locally (set `QD_API` to your gateway origin).
3. Try disconnect/reconnect wallet and hard refresh once.

## Wrong network in wallet

Switch your wallet’s cluster to match QuantDesk’s expectations for that URL (devnet vs mainnet-beta). Wrong cluster signatures **fail** — by design.
