Claims fixer

Requirements

go
mainnet genesis (wget https://archive.evmos.org/mainnet/genesis.json)
clawback block results (wget https://github.com/v-homsi/clawback/raw/main/evmos_mainnet_5074187_block-results.json)
evmosd node archive

Configuration

Inside the file internal/requester.go set your endpoint. It must be an archive node!

Usage

Note: if the process is killed nothing will be store in the database. Note: if you want to run the process again, make sure to remove the .db file.

git clone https://github.com/evmos/claims_fixer --depth 1
cd claims_fixer
wget https://archive.evmos.org/mainnet/genesis.json
wget https://github.com/v-homsi/clawback/raw/main/evmos_mainnet_5074187_block-results.json
go build
rm attestation_accounts.db
rm accounts_with_claims.db
rm results.db
./claims_fixer init
./claims_fixer process
./claims_fixer addAttestationRecords
./claims_fixer processAttestationRecords
./claims_fixer create
./claims_fixer calculateTotal

Results

The file results.db has the result of executing the process script. It's a table named claims with the columns:

address
amount

How it works

init: gets all the wallets that had claims records on the genesis file.
process: check if the account was affected by the clawback bug and add that account and the amount to the results.db database.
addAttestationRecords: using the block_result information from the clawback block, it gets all the addresses that sent their coins to the community wallet. Note: this block didn't have any transaction, so most of the wallets inside this file are from the clawback function.
processAttestationRecords: iterates using all the wallets added in the previous step and it makes sure that their balance was incorrectly moved.
create: it generates an account.txt file that contains the information needed for the evmosd network upgrade.
calculateTotal: it iterates the result.db rows and converts each amount to big.Int in order to call the Add function. It returns the total amount of aevmos that needs to be sent back to the users.

Evmos upgrade

For the network upgrade the values used are the ones in the accounts.txt file. That file was generated using the data from the result.db file.
