Union is partnering with Rome Protocol to bring trustless interoperability to Solana. Once complete, this integration will unlock decentralized asset transfer and message passing between the Solana ecosystem and all Union-connected chains—including Ethereum, Cosmos, Bitcoin L2s, and more.
The collaboration will leverage Union’s infrastructure and the Rome SDK to support secure cross-chain transactions, ensuring fast and reliable finality across chains.
Bringing Liquidity and Users to Solana
Since the inception of Union, people have been asking “wen Solana?”. The answer has always been tricky. Unlike the majority blockchains like Ethereum, Cosmos, and most alt-L1s, Solana doesn’t have a Merkle root, making it difficult to verify or include transactions from other blockchains.
That’s where Rome Protocol comes in. Rome modularizes Solana consensus into a set of enshrined services, including Rome EVM, Rome Shared Sequencer, Rome Interop, and Rome DA. Rome Interop is what we’re focused on here.
Rome Interop enables ETH ecosystem transactions to be atomically composable with Solana transactions. By using the Rome SDK, developers, searchers, and builders can compose atomic cross-rollup transactions involving Solana.
By combining Union’s infrastructure with the Rome SDK, Solana will be connected to the growing Union network, allowing for instant connection to one of the biggest and most dynamic blockchain ecosystems.
Connecting the Web3 World
With this partnership with Rome Protocol, Union will extend its connection to the biggest and most important blockchain ecosystems—Bitcoin, Ethereum, Cosmos, and now Solana.
But this is only the beginning. Union builders are fast at work connecting more ecosystems, and creating applications that will live at the heart of interoperability.
