Making Your First Deposit

The dreamDEX 101 walkthrough: connect a wallet, fund your account, and get the USDso you need to trade — all from the dreamDEX app.

What you'll need: an EVM wallet (MetaMask, Brave, or Rabby — or just an email / social login) and a few minutes. dreamDEX provisions a Privy-backed smart wallet for you; your keys stay self-custodial.

Building a bot or integrating programmatically? This guide covers the app UI. For the API, CLI, and direct-contract flow, see the Quick Start.

Connect your wallet

Open the app and click Connect Wallet

Head to app.dreamdex.io and click Connect Wallet in the top right of the order tab.

The dreamDEX order tab with the Connect Wallet button highlighted — The order tab — **Connect Wallet** is top right.

Pick your wallet

Choose MetaMask, Brave, or Rabby from the list — or log in with email or socials.

Connect Wallet modal listing MetaMask, Brave, Rabby, other wallets, and email/social login — Select a wallet, or use email / social login.

Approve the connection

Confirm the connection request in your wallet.

Waiting for MetaMask prompt with the wallet account selection — Approving the connection in MetaMask.

A 0 balance in MetaMask does not mean you have zero Somnia balance due the way Metamask currently calculates balances.

Sign to log in

This provisions your Privy smart wallet for account abstraction; you'll make 1–2 signatures. Signing proves you own the wallet — it doesn't move funds or cost any fees.

Wallet signature prompt: signing proves wallet ownership and does not cost any fees — The login signature — no transaction, no fees.

Fund your account

Click Deposit

In the account panel on the right, click Deposit.

dreamDEX trading view with the Deposit button highlighted in the account panel — The **Deposit** button in the account panel.

Choose your asset and source chain

Open the From dropdown and pick what you're depositing. We expect the most common deposits to be SOMI from Somnia, USDC from Arbitrum, or USDso on Somnia.

Deposit modal with the From asset dropdown highlighted — Open the **From** dropdown.

Expanded deposit asset dropdown showing ETH, USDC, WETH, USDC.e, WBTC, SOMI, and USDso — Supported deposit assets.

Enter an amount and confirm

In this example, depositing $100 of USDC from Arbitrum routes USDC → USDC.e → USDso. If auto-buy gas is on (the default while your trading account holds no SOMI), the app also buys 1 SOMI for your first transactions, as long as the deposit is worth at least about 1.1 SOMI, your account holds less than 0.05 SOMI, and at least 2 USDso is available after the conversion. WETH and WBTC deposits do not buy gas.

Deposit modal depositing $100 USDC from Arbitrum, receiving ~99.9 USDso plus 1 SOMI, route USDC to USDC.e to USDso — Depositing USDC from Arbitrum, received as USDso.

That's it — your assets are now on dreamDEX.

Fees. We're launching with zero trading fees — only (very small) gas fees. The SOMI ↔ USDso and USDC.e ↔ USDso pairs are sponsored; otherwise you need the network's native token (SOMI on mainnet, STT on Shannon testnet) for gas.

Deposits. Every pair trades against our stablecoin USDso. Bring USDC / USDC.e cross-chain and you'll receive USDso via our 1:1 swap contract (plus, optionally, some SOMI for gas); USDso is redeemable for USDC. Somnia-native assets can be deposited without bridging.

Getting USDso

Since every pair trades against USDso, you'll usually want some. There are three ways, easiest first:

Deposit (recommended). Click Deposit and use the module with USDC from one of the source chains in the Chain picker (bridged over LayerZero) — cheapest for most users.
Trade for it. Buy USDso on the USDC.e ↔ USDso CLOB pair.
Frax Mint & Burn widget (backup). Mint USDso directly through our partner Frax's embedded widget — walked through below.

Open Mint USDso

If you logged in with an external wallet and the Mint USDso button appears in the Portfolio header, click it, then click Next.

Mint USDso intro screen describing three steps: mint via FraxNet, track your mints, deposit into trading wallet — Mint via FraxNet → track the mint → deposit into your trading wallet.

Choose your source asset and chain

Select what you're minting from, then continue.

FraxNet Mint USDso widget swapping USDC.e on Somnia for USDso to the connected recipient wallet — Swap USDC for USDso in FraxNet — it lands in your connected wallet.

Confirm the mint

USDso mints 1:1 against USDC.e. Click Mint USDso.

Mint confirmation showing 1 USDC.e = 1.00 USDso with a Mint USDso button — 1 USDC.e = 1.00 USDso.

Wait for the mint to complete

Roughly 5–30 minutes depending on source asset and chain. Track progress here — it updates automatically until the USDso lands.

Mint status screen showing 0 in progress, 4 completed successful mints, and 0 failed — Mint status updates until USDso lands in your wallet.

Deposit into your trading wallet

Once the USDso is in your personal wallet, click Deposit to move it into your smart (trading) wallet. This deposit is a Somnia transaction and requires the network's native token (SOMI on mainnet, STT on Shannon testnet) in your personal wallet to pay the network gas fee.

You're funded and ready to trade.
