MXNB on Arbitrum

Overview

MXNB is an Arbitrum-compatible stablecoin that follows the ERC-20 standard, maintaining a 1:1 peg to the Mexican peso.

Using the ERC-20 standard for issuing the MXNB stablecoin smart contract enhances its trustworthiness and compatibility across multiple wallets and protocols, promoting liquidity and interoperability. The standard’s well-established codebase strengthens security, while its predefined functions simplify development.

Smart Contracts and Architecture

The MXNB stablecoin uses a proxy upgrade pattern, separating the token’s logic and data into distinct contracts. This approach enables seamless updates while preserving security.

Key contracts for developers seeking to use the MXNB token:

ERC-20 Implementation Contract: Contains the core business logic for the MXNB token, and it is the initial contract deployed on the Arbitrum blockchain.
Proxy Contract: Serves as an interface to the implementation contract. It holds the address of the implementation contract, delegating calls to it without containing business logic.

Developers should use the Proxy Contract Address for all interactions with the MXNB stablecoin.

Networks

MXNB is deployed on two distinct networks:

1. Arbitrum One Mainnet

The Mainnet, short for main network, is the primary and live blockchain where transactions hold real-world value. It is production-ready and incurs transaction fees.

Mainnet Details:

Network Name: Arbitrum One Mainnet
Token Standard: ERC-20
Decimal Precision: 6
Fiat Token Implementation Address: 0x72beddf7032EEC58F199857b79A8e37020c14e42
Proxy Contract Address: 0xF197FFC28c23E0309B5559e7a166f2c6164C80aA

2. Arbitrum Goerli Testnet

The Testnet, short for test network, mirrors Mainnet functionality but without real-world value, providing a safe and cost-free environment for experimentation, development, and testing.

Testnet Details:

Network Name: Arbitrum Goerli Testnet
Token Standard: ERC-20
Decimal Precision: 6
Logic Contract Address: 0xb56E3E3769EfB85214Cb4fA42eBA198E9FDA92bf
Proxy Contract Address: 0x82B9e52b26A2954E113F94Ff26647754d5a4247D
