TODO: manage Escrow accounts

[moul]

I find another edge case to manage: escrow accounts, i.e.

https://www.mintscan.io/cosmos/account/cosmos1x54ltnyg88k0ejmk8ytwrhd3ltm84xehrnlslf (looks like to be for osmosis).

~5M atom on may 20th. ~9M atom on the airdrop file.

$ gaiad q ibc-transfer escrow-address transfer channel-141 --chain-id 1 --node https://rpc.cosmos.network  

cosmos1x54ltnyg88k0ejmk8ytwrhd3ltm84xehrnlslf

I suggest that we just skip them completely.

yes, it should definitely be omitted, evmos found this issue when it finished its airdrop.

a snippet to get the escrow address:

import (
"crypto/sha256"
"fmt"

"github.com/gnolang/gno/pkgs/bech32"

)

func GetEscrowAddress(portID, channelID string) (string, error) { contents := fmt.Sprintf("%s/%s", portID, channelID)

preImage := []byte("ics20-1")
preImage = append(preImage, 0)
preImage = append(preImage, contents...)
hash := sha256.Sum256(preImage)

return bech32.Encode("cosmos", hash[:20])

}

// GetEscrowAddress("transfer", "channel-141")
