# Wallet setup

> Install a Solana wallet, fund it with USDC, and connect to Parquet — Phantom and Solflare walkthrough.

This page walks you from a fresh browser to a connected wallet holding SOL for fees and USDC for collateral, ready to open positions on [parquet.exchange/trade](https://parquet.exchange/trade).

## 1. Install a supported wallet

The app accepts two wallet adapters today: **Phantom** and **Solflare**. Either works the same once connected — pick whichever you already use, or Phantom if you have no preference.

* **Phantom** — [phantom.app](https://phantom.app). Browser extension on Chrome, Brave, Firefox, Edge; iOS and Android apps.
* **Solflare** — [solflare.com](https://solflare.com). Browser extension and mobile apps. Hardware wallet support (Ledger) is more mature than Phantom's if you plan to plug in a device.

Install the extension, create a new wallet, and write down the seed phrase on paper. Don't paste it into a password manager you sync to the cloud, and never share it.

## 2. Fund the wallet with SOL

You need a small amount of SOL (under 0.1 is plenty) to pay Solana transaction fees. Buy from any Solana on-ramp (Coinbase, Kraken, Binance, MoonPay, etc.) and withdraw to your wallet's address, or transfer from an existing Solana wallet.

## 3. Fund the wallet with USDC

Parquet uses USDC as the only collateral asset. The protocol minimum is **\$10** per position. Get USDC the same way as SOL — buy on a centralized exchange and withdraw to your wallet, or swap inside a Solana DEX from another token you already hold.

<Tip>
  If your wallet shows "USDC" with a tiny icon, hover or expand the entry to confirm it's the canonical mint, not a copy-cat. Real USDC on Solana mainnet is mint `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`. On devnet, Parquet uses a mock USDC mint at `DA8DJqnj49QrNN6TSbZ13cMubdJ8agSeEohH5AGjkgYA`.

## 4. Connect and verify

Open [parquet.exchange/trade](https://parquet.exchange/trade) and click **Connect Wallet**. Pick your wallet from the modal, approve the connection, and check that the header shows your address truncated and your USDC balance.

You're ready. Head to [first trade](/getting-started/first-trade) to open a position, and read [risks](/reference/risks) before you size anything you'd care to lose.

<Note>
  Deposits use the real Solana USDC mint `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`; acquire USDC from any Solana DEX or transfer from a centralized exchange. All Parquet markets trade 24/7. Read the [risk disclosure](/reference/risks) before trading.
</Note>

<Tip>
  **SDK developers testing on devnet:** Parquet's devnet mock USDC mint is `DA8DJqnj49QrNN6TSbZ13cMubdJ8agSeEohH5AGjkgYA`; mock USDC is minted to test wallets by the devnet tooling. Devnet positions do NOT settle to mainnet.
