Dinner with your crypto friends tends to end in an uncomfortable question: who is going to pay?
On Rome, the MetaMask user and the Phantom user pay into the same contract and see the same balance. One Solidity contract, no bridge.
Open idea for Arena builders, via @Daan618crypto.
Another week, another solid update from @RomeProtocol as they keep building step by step.
As you know, I'm a technical analyst, not a builder or dev. So this week I'm in Dream it mode, with an idea for the Rome Arena that launched last week 👀
Rome already made EVM and Solana one market. Arena is the next layer, where builders put their apps on Rome and register their contracts.
My idea for builders 🧠
Every crypto group chat has the MetaMask friend and the Phantom friend. Going for dinner or booking a weekend? Splitting the bill turns into a mess of screenshots and "I'll send it later."
The fix: one shared pot on Rome. Both wallets pay into the same pot. Everyone sees the same balance. When the bill comes, it pays out once.
That only works if MetaMask and Phantom share the same state. On separate chains you're back to bridging or picking a side.
Every Rome app starts with someone asking "what if both sides could use this?" 🏛️
Unchanged @aave V3 and V4 runs on @solana for Solana users and EVM single market for both. We need to aave on solana check integration on solana devnet aave.testnet.romeprotocol.xy…

Ostia is live on Canton DevNet: a ZK EVM on Canton. Every block is proven and settles on Canton.
Deploy Solidity. Move tokens between Ostia and Canton. Open source, Apache-2.0, open to all.
@CantonNetwork @CantonFdn @CantonArmy

On the Bridge: move Canton Coin onto Ostia as an ERC-20. Move Ostia tokens onto Canton as twins. Move them back. Send them on Canton.
No Canton wallet yet? Sign one message in MetaMask and you have a Canton account.

Solana and EVM one market
Crypto’s two largest application ecosystems still operate like separate worlds.
Builders duplicate products, institutions duplicate controls, and users and capital remain fragmented.
@RomeProtocol is turning that boundary into one connected market.
Rome makes EVM and Solana one market.
Arena is live. Put your app on Rome or become an ambassador. Both earn Laurels, records of activity.
Start here, in four steps:
arena.mainnet.romeprotocol.x…
Build. Scaffold an app where one Solidity contract serves both MetaMask and Phantom:

Hadrian
@useteller's fixed-term lending proof of concept is live on Hadrian, Rome's devnet. It uses test assets.
@RomeProtocol makes is less weird something dropping...
@solana is positioned as capital markets for everything. A market is only as big as who can reach it. Rome opens Solana markets to EVM users with an EVM wallet, alongside Solana users with a Solana wallet. Build on @RomeProtocol incentives for builders loading...

Alpenglow is live. Congrats @anza_xyz — finality just went from ~12.8s to ~150ms.
Rome EVM’s Rubicon inherits that directly (it runs as a native program inside @solana ). Every EVM tx settles with Solana’s finality.
Fastest EVM cryptographic finality right now.

Rome stack is open, our multichain program on Solana is audited by @HalbornSecurity Chain is alive. builders are building. Bridge and bridge api are open to rome and other EVM chains. Oracle feed with chainlink compatible inefrace is live on mainnet and testnet. full stack open github.com/rome-protocol/ with examples and docs walk you though on how to build applications that bring the worlds together docs.rome.builders
Crypto’s two largest application ecosystems still operate like separate worlds.
Builders duplicate products, institutions duplicate controls, and users and capital remain fragmented.
@RomeProtocol is turning that boundary into one connected market.
Kamino lending, open to @0xPolygon users.
Portus now serves Polygon users. Base users were first. Same app, same self-custody model, reaching Kamino’s Main lending market on @solana.
Deposit and earn
Deposit USDC and earn in @KaminoFinance. You sign on Polygon and stay there. Portus shows live market rates read from Solana. Withdrawals return USDC to the same Polygon address.
How it works
Circle CCTP carries your USDC and signed instructions to a contract on Rome. The contract deposits into Kamino and accounts for your position. Rome runs EVM chains inside Solana’s runtime, letting the contract call Solana programs directly in one transaction.
Open stack
Portus is built on Rome. Rome’s whole stack is open on GitHub. Any team can build an app like this, from any EVM chain, reaching any Solana dapp.

Private AMM live on Solana devnet using @HeliusPrivacy give it a try.
privacy-dex.devnet.romeproto…
Privacy DEX is live on Solana devnet.
Private swaps on Solana, built on @HeliusPrivacy. Pay USDC, receive SOL into a private balance. The token and amount you hold are encrypted on chain.
Built by Rome. Thanks @0xMert_ and the Helius team for the shielded pool.
Portus is live portus.mainnet.romeprotocol.…
Base users can reach @solana with self-custody. They sign on @base without leaving it.
Deposit USDC into @kamino lending markets. Circle CCTP carries the USDC and the user's signed instructions to a contract on Rome. The contract deposits into Kamino and accounts for the position. Withdrawals return USDC to the same Base address. The app shows live market rates read from Solana.
How it works
Rome runs EVM chains inside Solana's runtime. A contract on Rome can call Solana programs directly in one transaction.
Build on Rome
Rome's whole stack is open on GitHub. Any team can build an application like this from any EVM chain, reaching any Solana dapp.

Rome's full stack is open on GitHub: the EVM program that runs inside Solana's runtime, the SDKs, the node stack, the Solidity library, the CLI and the registry. Builders can run their own chain on it.
The EVM program deployed on Solana mainnet has been through three @HalbornSecurity engagements, two in 2025 and a 2026 review of the deployed build. The executive summaries are published in full, and the deployed binary reproduces from the audited tag.

Ostia is open source.
An EVM chain where every block is proven with ZisK, then settles on @CantonNetwork in one transaction with the Daml actions it needs.
Early release, not audited. Apache-2.0. Try it and tell us where it breaks.
Proofs by @ziskvm.
Ostia checks each proof through Canton's external call, which @ZenithFdn implemented for Canton. Thanks to them, and to the ZisK team for the prover.
