Solaxy is a new crypto project building a Solana Layer-2 network with a planned Ethereum bridge, token launchpad, wallet integration, and decentralized exchange (DEX). With the SOLX token launch expected soon and the crypto presale raising nearly $50 million, we analyzed what technologies the project is using and how much original development is involved.

Solana Layer-2 with SP1 zkVM Integration

Solaxy uses SP1 zkVM, a zero-knowledge virtual machine built by Succinct Labs, to run Solana smart contracts off-chain. This lets the network generate cryptographic proofs for off-chain transactions, improving scalability while maintaining security. Solaxy didn’t build this system themselves but adapted it to run Solana programs.

Sovereign SDK for Rollup Sequencing

To manage how transactions are ordered and batched, Solaxy integrates the Sovereign SDK from Sovereign Labs. This handles the core rollup functionality and includes soft confirmations that tell users their transactions are accepted almost instantly. Solaxy added its own modules and adapted the SDK to work with Solana’s format.

Celestia for Off-Chain Data Availability

Solaxy uses Celestia to store transaction data off the Solana mainnet. This off-chain storage helps reduce network congestion while keeping data accessible for verification. Solaxy integrated Celestia’s API and client tools to automatically post rollup data in a verifiable way.

Hyperlane for Ethereum Bridge

For cross-chain messaging and asset transfers between Solana and Ethereum, Solaxy uses Hyperlane. The bridge relies on Hyperlane validators and smart contracts already deployed on both chains. Solaxy reused Hyperlane's tools to create a working connection between its Layer-2 and Ethereum.

Combining Open-Source Tools with Custom Features

Solaxy’s architecture blends existing components—zkVM, Sovereign SDK, Celestia, and Hyperlane—with internal development. Their team built some custom features like a launchpad protocol (Igniter) and wallet integration, but most core infrastructure relies on proven frameworks.

Does the Stack Justify the $50M Raised?

While the use of modular tools can accelerate development, the heavy reliance on third-party frameworks raises reasonable questions about how the $50M raised in the Solaxy crypto presale is being allocated. There is limited evidence so far of original infrastructure development.
