CRU Claim Back

If you want to map Crust Maxwell CRU back to ERC20 CRU, you can follow this tutorial step by step to claim back ERC20 CRU.

Attention

  1. Claim back will not arrive in real time, each claimback's cycle is: 3 months
  2. A certain amount of CRU will be deducted as the Ethereum gas fee, the claim back fee is: 1 CRU

The sum of multiple transfers in the same claim back cycle needs to be greater than claim back fee, if your claim back amount is less than the fee, it will be judged as invalid and will not be executed

  1. After the end of each claim back cycle, the total claim back tokens will be burned on the Crust Maxwell Preview network to ensure data consistency between the claim pool and the claim back pool

Steps

I. Bond Ethereum Address

First of all, ⚠️you need to bind your Ethereum address. Please note that for claim back transactions that are not bonded with an Ethereum address, you may lose the claim back CRU⚠️, so be sure to bind the Ethereum address you need to claim back.

  1. Through Crust Apps's Extrinsics Page, select claims and bondEth, and fillin the Ethereum Address which you wanna claim back.

  1. When sending extrinsic successfully, please double confirm the bonding information by query from Crust Apps's Chain State Page, if shows none, please repeated step 1.

II. Send Claim Back Transaction

Next, you need to initiate a CRU transfer transaction to the Crust Maxwell Certified Claim Back Address on Crust Maxwell Preview Network online. This operation needs to be performed on Crust Apps's Account Page. Please be sure to read before initiating the transfer:

  1. Crust Maxwell Certified Claim Back Address: 5HbMS3P5e6rMP9KTDkVTZCaytKQkbqsV7HGnxgAgvv5d64tx (Certified with name: Token Bridge<ERC-20>🚗💰)
  2. ⚠️ Note that within a claim back cycle (7 days), you need to ensure that the total claim back amount is greater than 1 CRU
  3. The account that initiated the transfer back transaction has performed Step I to bond the Ethereum address

III. Follow-up

After performing Step I and II:

  1. All claim back transactions will be cleared within a claim back cycle
  2. The claim back sender's address is same as claim address: 0x17a9037cdfb24ffcc13697d03c3bcd4dff34732b, you can find all the transactions and operations in this address
