Quickstart

From zero to first leveraged position in five minutes. Bridge USDC.e to Arbitrum, connect a wallet, sign once - that is the whole onboarding.

Overview

Atomic has no account creation, no KYC, and no deposit step. Funding live on Arbitrum + an EVM wallet is everything you need.

What you'll need

An EVM wallet (MetaMask, Rabby, or any WalletConnect-compatible client) and either USDC.e or ETH on Arbitrum. That's it.

1. Install a wallet

Any EVM-compatible wallet works. Atomic is tested daily against:

  • MetaMask - browser extension, the default for most users.
  • Rabby - recommended for power users (better transaction previews, multi-chain UX).
  • WalletConnect - if you prefer a mobile wallet (Rainbow, Trust, etc.).

2. Bridge funds to Arbitrum

Atomic runs on Arbitrum One. Trading margin is denominated in USDC.e; ETH is needed only for gas.

| Bridge | Notes | |---|---| | bridge.arbitrum.io | Official, slowest withdraw path back to L1. | | Stargate | Fast, supports many source chains. | | Across | Cheapest for small transfers. | | Orbiter | Lowest latency for L2-to-L2 moves. |

A few dollars of ETH on Arbitrum is enough for many transactions.

3. Swap USDC to USDC.e

!
USDC vs USDC.e — they are different tokens

Atomic settles in USDC.e (the bridged USDC, also known as USDC.e or USDC bridged from Ethereum). Most bridges deliver native USDC (Circle's CCTP-issued token on Arbitrum), which is a separate ERC-20 with a different contract address. You need USDC.e to open positions and to provide lending liquidity.

If you arrived on Arbitrum with native USDC, swap it to USDC.e on any DEX before continuing:

| DEX | Notes | |---|---| | Uniswap | Deepest USDC ↔ USDC.e pool on Arbitrum. | | Camelot | Native Arbitrum DEX, often the best route for size. | | 1inch / ParaSwap | Aggregators — they will pick the best path automatically. |

The two tokens trade at parity (1:1) under normal conditions; the swap is effectively a token-format conversion with minimal slippage.

4. Connect to the app

  1. Visit app.atomic.green.
  2. Click Connect Wallet in the top right.
  3. Pick your wallet provider and approve the connection.
  4. Confirm you are on the Arbitrum network - the app will prompt to switch if not.
i
One-time signature

On your first visit you will be asked to sign a one-time agreement. This is a gasless signature - no transaction is broadcast, no fee is paid.

5. Approve the asset (one-time per market)

The first time you trade a given market, the app will ask you to approve the underlying token spend. This is a standard ERC-20 approval and only happens once per asset.

6. Open your first position

  1. Pick a market from the list at the top.
  2. Choose Long or Short.
  3. Enter the margin amount in USDC.e.
  4. Set leverage (1x–20x - see Leverage & margin).
  5. Review the order panel - most importantly the liquidation price.
  6. Click Buy (or Sell for a short) and sign the transaction.

The position appears in Open Positions the moment the transaction confirms.

7. Manage the position

  • Take Profit / Stop Loss - click Edit on the open position to set or change targets. No fee applies to setting, editing, or cancelling them.
  • Close - click Close at any time and sign the transaction. Margin minus fees and PnL settles back to your wallet in the same block.
