  1. Products & Ecosystem

Chain Router

Novastro’s Cross-Chain Bridge & Messaging Hub is the behind-the-scenes engine that allows Novastro-issued tokens (DTC-based RWA tokens) to flow frictionlessly between Ethereum (issuance layer) & Arbitrum, Solana, Sui, and other supported ecosystems (trading layer).

What Is It?

The Cross-Chain Bridge & Messaging Hub is a foundational Novastro module that:

  • Handles interoperability between multiple blockchains

  • Uses trusted, secure third-party bridges (Wormhole, LayerZero, Axelar)

  • Manages token transfers, fee payments, and chain-specific logic

  • Enables RWA tokens to function multichain without worrying about infrastructure

The module comprises:

  • Smart contracts deployed on Ethereum and supported destination chains

  • Off-chain relayers/oracles that monitor events and pass messages

  • A unified API/interface used by other Novastro components for sending/receiving tokens or data across chains

How It Works (Step-by-Step)

Example: Moving a Token from Ethereum to Solana

  1. User Request Initiation The user initiates a transfer via Novastro’s interface—choosing to move a token from Ethereum to Solana.

  2. Token Locking (Ethereum Side) The bridge contract on Ethereum locks the original token in a vault. This ensures the total circulating supply remains secure and traceable.

  3. Message Relay An off-chain relayer or oracle picks up the event and communicates it to the Solana-side bridge contract via Wormhole, LayerZero, or Axelar.

  4. Token Minting (Solana Side) A corresponding wrapped token is minted on Solana, 1:1 matched with the locked token on Ethereum.

  5. User Receives Token on Solana The user now holds the same RWA token, but usable within the Solana ecosystem.

  6. Return Path (Solana to Ethereum) When moved back, the wrapped token is burned on Solana, and the original is unlocked on Ethereum.

Fee Abstraction

Cross-chain transfers usually require native gas tokens on each chain. Novastro abstracts this complexity:

  • Users can pay fees in ETH, $NOVAS, or other supported tokens

  • The hub handles gas conversion and pays the required fee on the destination chain

Result: Users don’t need to keep wallets topped up with Solana, SUI, or ARB tokens.

Why are We Using Third-Party Bridges?

Instead of building a custom bridge (which increases risk), Novastro leverages top-tier, audited networks:

  • Wormhole – Used by many leading DeFi apps across Solana and Ethereum

  • LayerZero – Known for ultra-fast messaging and minimal trust assumptions

  • Axelar – Offers general message passing and secure asset transfers

This allows Novastro to focus on product innovation while relying on proven security for interoperability.
