Deposit Methods Overview
Aura supports four paths for getting funds into your account. The right one depends on what you hold today and which venue you're trading on.
Pick by what you have
| You have… | Depositing to Hyperliquid | Depositing to Polymarket |
|---|---|---|
| A credit/debit card or bank account | Fiat onramp (Helio) | Fiat onramp (Helio) |
| Crypto on another chain (BTC, ETH, SOL, etc.) | Crypto onramp (Helio) | Crypto onramp (Helio) |
| USDC.e on Polygon already | — | Direct to Safe |
| An external wallet (MetaMask, Rainbow, etc.) you want to sign in with | Bring Your Own Wallet | Bring Your Own Wallet |
The methods
Fiat onramp (Helio)
Buy with card or bank transfer via the Helio Deposits widget. USDC is delivered straight to your Hyperliquid spot account; pUSD is delivered to your Polymarket Safe. Open the deposit modal and pick Fiat.
Crypto onramp (Helio)
Bridge from another chain via the Helio Deposits widget. Pick the asset and source chain inside the widget; Helio handles the wrap and delivery. Open the deposit modal and pick Crypto.
Direct deposit to Polymarket
Send USDC.e on Polygon directly to your Polymarket Safe address. No onramp, no bridge — just copy the address and send. First deposit triggers Safe deployment.
Bring Your Own Wallet (BYOW)
Sign in with an external wallet. On web: Privy's wallet modal supports MetaMask, Rabby, Coinbase Wallet, and WalletConnect QR. On mobile: Reown AppKit over WalletConnect v2. BYOW is an authentication method — your external wallet becomes your trading identity. Fund it however you'd normally fund a wallet, then use the crypto onramp to move funds onto Hyperliquid or Polymarket.
How detection works
Once you send, Aura watches your destination account and advances the flow automatically. If detection stalls, see Deposit Not Detected — it covers the most common "I sent it, where is it" scenarios across all four methods.
What Aura never does
- Aura never holds your deposit in an intermediate account. Funds go directly to Hyperliquid (via the onramp or bridge) or to your Polymarket Safe.
- Aura never asks you to sign a transaction that transfers your existing wallet balance. Deposit flows only show receive addresses — if something prompts you to send from your wallet without showing a destination you control, stop and contact support.
