Cross-Chain

M0 on EVM

M0 is designed for a multichain world, enabling M0 extensions to be accessible across various blockchain ecosystems while maintaining Ethereum as the authoritative source for governance.

Portal V2

Portal V2 is M0's bridging infrastructure that transfers M extensions across supported chains. It locks or burns tokens on the source chain and mints or unlocks them on the destination chain, enabling secure 1:1 transfers.

Messages travel through modular bridge adapters rather than a single messaging protocol. Each adapter passes raw, byte-encoded Portal messages through its provider's base messaging layer. The following adapters are currently supported:

• Wormhole — messages are published through the Core Bridge contract and delivered by the Executor
• Hyperlane — messages are dispatched and delivered through the Mailbox contract
• LayerZero — messages are sent and received through the Endpoint contract

If your desired blockchain is not yet supported through these providers, please reach out to discuss custom integration possibilities.

M0 on Solana

The M0 platform extends its reach beyond EVM chains by offering a native deployment on the Solana blockchain. This provides the Solana ecosystem with direct access to secure stablecoin building blocks, unlocking new possibilities for high-performance DeFi, payments, and other applications.

This is a native representation, inheriting its core properties of security and rewards accrual while leveraging Solana's speed and low transaction costs.

How It Works: A High-Level View

Portal V2 allows bridging of M0 extensions to Solana via its Wormhole adapter, following the same hub-and-spoke model used for EVM chains:

1. Lock on Ethereum: To move extensions to Solana, the native token is locked in the HubPortal contract on Ethereum.
2. Message with Wormhole: A secure message is sent via the Wormhole network to Solana.
3. Mint on Solana: The Portal program on Solana receives the message and mints an equivalent amount of the native Solana extension (an SPL token).

This process ensures that every extension on Solana is fully backed by a corresponding token locked on Ethereum, maintaining the integrity of the total supply.

Key Features for Solana Users & Developers

• Native Rewards: Stablecoin extensions on Solana are designed to be rewards-accruing. The earning index from Ethereum is propagated via Wormhole, allowing Solana holders to benefit from the same underlying collateral rewards.
• High Performance: Leverage Solana's sub-second finality and low fees for transactions.
• Deep Integration: Extensions can be native SPL tokens or follow Token-2022 for more advanced functionality. This means that extensions can be seamlessly integrated into Solana's vibrant DeFi ecosystem, including DEXs, lending protocols, and derivatives platforms.
