// Relays Ethereum -> Gnosis Chain Omnibridge messages by calling
// executeAffirmation() on the AMB home bridge as a bridge validator.
//
// Direction note: this is the *opposite* of callExecuteSignature.js /
// claimAll.js. Those handle GC -> ETH, where validators sign on GC and anyone
// submits the collected signatures on ETH. Here the user request originates on
// ETH (UserRequestForAffirmation on the foreign AMB) and each validator
// independently confirms it on GC with executeAffirmation(bytes). There is no

// Sign Omnibridge (AMB) messages with a validator private key.

// Usage:
//   node manual_sign_omni.js <private-key>
//
// Reads:  omnibridge_tx_to_sign.csv   (columns: Tx Hash, Message, Origin)
// Writes: omnibridge_tx_signed.csv    (adds a Signature column)
//
// Each Message is a raw hex payload. Bridge validators sign it with the
// EIP-191 personal_sign scheme (\x19Ethereum Signed Message:\n<len> prefix

Canonical Bridge Upgrade Checklist

This article outlines the steps required for the canonical bridge upgrade.

Components:

1. Smart Contract

1. Discussion Phase:
2. Does the design involve only a single chain or both chains?
