AURA Swap Instructions
Since 2019, AURA tokens can be swapped to IDEX tokens. There's no deadline for the swap.
ATTENTION: THIS IS THE ONLY WAY TO SWAP AURA TOKENS. SENDING AURA TOKENS TO A SMART CONTRACT WILL RESULT IN THE TOKENS BEING LOST.
The following steps document swapping AURA tokens for IDEX tokens on the Ethereum mainnet using MyEtherWallet.

Step 1 - Approve

  • Load https://www.myetherwallet.com/wallet/interact unlock your wallet if necessary. Make sure to select the Ethereum network.

  • Into the ABI/JSON Interface field, copy the the “Contract ABI” code from the contract: https://etherscan.io/address/0xcdcfc0f66c522fd086a1b725ea3c0eeb9f9e8814#code
  • Click the “Interact” button to continue.
  • Select approve from the drop down on the right.

  • Into the _value field, enter the desired amount of tokens to be swapped. Note the amount needs to include the full precision, so 10 AURA would be 10000000000000000000. Make sure there are no spaces before or after the number, or the button will get disabled.
  • Write/sign the transaction.

  • Click the “Interact” button to continue.

Your IDEX tokens will be sent back to you at a 1 to 1 ratio. The AURA you sent is locked forever in the IDEX token contract. You can now deposit or stake your IDEX tokens!
