M^0

M^0 Lab’s Engineering Team would like to add the pre-determined address of the Noble Portal contract to the Earners list.

Noble is an application-specific blockchain (or “appchain”) designed to simplify stablecoin transfers across multiple blockchains using the Inter-Blockchain Communication (IBC) protocol. It serves as a bridge between stablecoin issuers, enabling their stablecoins to be integrated with an expanding network of Cosmos-based chains.

The Noble Dollar($USDN) will be a dollar stablecoin issued on the Noble chain as an extension of $M. The Noble Portal serves as the entry point of $M infrastructure on the Noble chain, leveraging Wormhole NTT Manager to facilitate the bridging of $M into Noble and enable the minting of $USDN.

Announcement

Noble Portal will be deployed by the wallet with the following address: 0xF2f1ACbe0BA726fEE8d75f3E32900526874740BB.

Noble Portal relies on the ERC-1967 Proxy pattern for upgradability and the CREATEX Factory will be used to deploy the Noble Portal proxy via CREATE3 at the following pre-deterministic address: 0x83Ae82Bd4054e815fB7B189C39D9CE670369ea16

This address can be verified by calling CREATEX function computeCreate3Address(bytes32 salt) with this salt: 0xd6c6b76aa7777f43f6d4889fd534a68dffe9a87489b5851ce35650b9636eb43f

This salt is computed by concatenating the deployer address with the NoblePortal contract name and is hashed with the deployer address to guard against deployment by another wallet. The Solidity code computing this guarded salt can be found here. The code used to deploy the Noble Portal proxy and implementation is available here.

Cyfrin and Kirill Fedoseev conducted two external audits. Their respective reports are published here. Additionally, Noble Portal was internally audited by Asymmetric Research.
