Rome Protocol Opens Hadrian Testnet for EVM Apps on Solana

The Hadrian environment operates on the Solana Devnet, utilizing a proxy system that packages Ethereum-style transactions for execution by Solana validators. This architecture enables Solidity contracts to interact with native Solana programs via cross-program invocation, effectively bridging the gap between Ethereum’s familiar toolset and Solana’s high-throughput runtime. Developers can manage transaction pricing through configurable operator settings, which utilize Meteora pools or Pyth/Hermes for real-time gas price conversions.

While the project highlights Compound v3 and Aave v3 as reference applications, these remain demonstrations rather than official protocol migrations. Rome’s documentation clarifies that these implementations are currently confined to the testnet, with no confirmation that the governing bodies of either lending platform have sanctioned production deployments. The network enforces specific constraints, including a 64-address limit per transaction and a cap of 1.4 million compute units, requiring developers to monitor actual Solana compute consumption rather than relying solely on EVM gas metrics.

Security and infrastructure remain central to the rollout. Rome reports that its EVM program has undergone an audit by Halborn, though the documentation notes functional differences from Ethereum, such as the exclusion of modular-exponentiation. Deployment authority for the mainnet program is currently held by a Squads multisignature wallet, signaling a focus on decentralized control as the project expands its reach, including earlier initiatives targeting tokenized assets and cross-chain payments in Latin America.
