## Short Summary
Recovery of lost tokens in the bridge transaction.

## High level objective
Mint the lost tokens into a keyless account and force transfer the amount to the affected wallet.

## Background
The 3rd October at 4:56:54 (UTC), a user attempted to bridge CFG tokens from Centrifuge to Ethereum.

```
Bridge direction: CFG -> wCFG

Affected wallet address: 4bXMbJq5Et849m7cnic4xuGLjkMC3KvNmM9PJi2hFaXR2wg2

Tx link: https://centrifuge.subscan.io/extrinsic/6431655-2

Value: 626,070.8929 CFG + 100 CFG Bridge Fee = 626,170.8929 CFG
```

The transfer failed due to rate limiting on the infura endpoints that we were using to query Ethereum. The fix consisted in switching to tenderly endpoints.

## Description of Activity

Since the tokens were deducted from the source account, but they have never been minted or wrapped on the destination account, the tokens have been marked as lost.
This means that the tokens were deducted from the circulating supply and they have never been minted on the destination network.

This proposal aims to restore lost tokens on affected accounts by minting the total lost balance in a keyless account and then “force transfer” the corresponding amounts to affected address.

Calculation:
```
Total CFG lost: 626,070.8929 CFG
Bridge Fees: 100 CFG
Grand Total CFG: 626,170.8929
```

## Change or improvement
Recovering the lost tokens on affected wallet address.

## Alignment to the mission of Centrifuge DAO
Transparency and accuracy are fundamental in Centrifuge DAO.
Recovering the lost tokens will restore financial accuracy and ensure that all financial activities are accurately recorded and accounted for.
