SupraNova is Live on Public Testnet: The First Truly Bridgeless Cross-Chain Messaging 

Chains are silos. Liquidity is fragmented. Data is locked behind bridges that introduce new points of failure. Today, we break through those walls with SupraNova, a truly bridgeless cross-chain communication protocol, now live on Supra’s public testnet on SupraNova.ai. With this release, Supra Testnet ↔ Ethereum’s Sepolia Testnet messaging is now in public, bringing atomic, secure interoperability without middle multi-sig bridge services.

Think of it like locking $ETH on Ethereum and seeing it appear on Supra Testnet in under a minute, without an external bridging service in between. Every proof you submit carries Ethereum’s validation weight, preserving the source chain’s security guarantees on Supra’s Layer-1. Invalid proofs are simply rejected, cutting out any extra attack surface.

“With cross-chain communication embedded in our L1, every proof aligns with the source chain’s own validators. That’s real trustlessness.” — Jon Jones, CBO

Bridgeless by Design

SupraNova.ai natively verifies external-chain consensus on Supra Layer-1. When you submit a Ethereum Beacon State (signed by Ethereum’s Sync-Committee) and event proof to Supra, our protocol recomputes it in a single step, preserving Ethereum’s full security guarantees and eliminating any third-party attack vector.

• No middle network bridge to worry about.
• No multisig keys to worry about.
• No additional attack surfaces, invalid proofs are simply rejected.

Verification runs in sub-minute time, with gas fees paid in $SUPRA with the gas cost per transaction being about the same as a standard transaction on Supra.

“SupraNova.ai proves that cross-chain flows can be as secure as the chains themselves, without any kind of shortcuts or compromises. In time, we will provide AI-assisted smart routing across multiple chains and ecosystems too!” — Joshua Tobkin, CEO

What’s Next

As SupraNova.ai unlocks secure bridgeless cross-chain interoperability across Layer-1 ecosystems, we invite developers, protocols, and ecosystem collaborators to experiment with this public testnet release and help shape the future of programmable cross-chain finance. 

Right now, we’re working towards extending testnet support to other EVM chains as well as to Aptos and Sui, while transitioning SupraNova into mainnet beta within Q2 2025 if all goes well, paving the way for real-value, bridgeless transfers at scale.

As SupraNova.ai embarks on this journey, we invite you to push it to its limits. Build on it, experiment with it, and let us know what you discover. Your feedback will guide the evolution of bridgeless interoperability. 

Join our developer community on Discord for real-time support, share your experiences on X, and help shape the future of truly seamless cross-chain decentralized finance. We can’t wait to see what you do.
