Bridging to Aura

Aura runs on Alephium with USDT as the trading currency. If you're coming from Ethereum or BNB Chain (BSC), you'll need to bridge your USDT to Alephium via our integrated bridge. This process is simple, secure, and typically takes 10-20 minutes.

Why Bridge?

Aura uses USDT on Alephium for all trading, deposits, and payouts. If your USDT is currently on Ethereum or BSC, bridging moves it to the Alephium network where Aura operates. Benefits include:

• Lower fees: Alephium transactions cost a fraction of Ethereum gas fees

• Faster trading: Near-instant transaction settlement

• Full compatibility: Your bridged USDT works seamlessly across all Aura markets

Supported Chains

You can bridge USDT to Aura from:

• Ethereum (ETH) - USDT on Ethereum mainnet

• BNB Chain (BSC) - USDT (BSC-USD) on BNB Smart Chain

How Bridging Works

Aura uses the Wormhole bridge protocol, one of the most trusted and battle-tested cross-chain bridges in crypto. Here's what happens when you bridge:

1. Lock: Your USDT is locked in a secure Wormhole contract on the source chain (ETH or BSC)

2. Attest: A network of 19 independent Wormhole Guardians verifies and signs the transaction

3. Mint: Once verified, wrapped USDT is minted on Alephium and sent to your Aura wallet

4. Trade: Your USDT is now ready to use on Aura!

Step-by-Step: Depositing via Bridge

1. Connect to Aura: Sign in with your passkey or Alephium wallet

2. Click "Deposit": Open the deposit modal from the top navigation

3. Select Source Chain: Choose Ethereum or BSC depending on where your USDT is

4. Connect EVM Wallet: Connect your MetaMask, WalletConnect, or other EVM wallet

5. Enter Amount: Specify how much USDT you want to bridge

6. Approve & Bridge: Confirm the transaction in your wallet

7. Wait for Completion: The bridge typically takes 10-20 minutes

   • You'll see status updates: "Transferring" → "Attesting" → "Completed"

8. Start Trading: Once complete, your USDT appears in your Aura balance

Is It Safe?

The Wormhole bridge is one of the most secure cross-chain protocols:

• Battle-Tested: Wormhole has processed billions of dollars in transfers

• Audited: Multiple security audits by top firms

• Non-Custodial: Your funds move directly from your EVM wallet to your Aura wallet

1. Click "Withdraw" in the Aura app

2. Select your destination chain (Ethereum or BSC)

3. Enter the amount and your EVM wallet address

4. Confirm the transaction

5. Wait for the bridge to complete (~10-20 minutes)
