Getting Started
Sign in, deposit USDC, and place your first trade on Scalar.
Prerequisites
- An email address or an EOA wallet (MetaMask, Rabby, etc.)
- USDC on the supported chain
Account Types
Scalar supports two login methods. Regardless of which method you choose, an embedded wallet is created for your account automatically.
Sign in with your email address. An embedded wallet is created and used for all onchain actions. No wallet extension or browser plugin required.
Connect an Externally Owned Account (EOA) such as MetaMask or Rabby. An embedded wallet is still created and used by default. You can optionally switch to your EOA in settings.
Why embedded wallets?
The embedded wallet handles all onchain interactions (orders, deposits, withdrawals) on your behalf. This means:
- No pop-ups. No signature prompts or transaction approvals interrupting your workflow.
- Instant execution. Actions submit immediately without waiting for manual wallet confirmation.
- Non-custodial. Scalar does not have access to your embedded wallet's private key. You retain full ownership of your funds.
