+## 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.
