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).
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
Example: Moving a Token from Ethereum to Solana
User Request Initiation The user initiates a transfer via Novastro’s interface—choosing to move a token from Ethereum to Solana.
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.
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.
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.
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.
User Receives Token on Solana The user now holds the same RWA token, but usable within the Solana ecosystem.
Return Path (Solana to Ethereum) When moved back, the wrapped token is burned on Solana, and the original is unlocked on Ethereum.
