Orbs launches V5 on Ethereum, Arbitrum to cut verification costs
Orbs launched V5 on Ethereum and Arbitrum to cut cross-chain verification costs, reduce infrastructure overhead and broaden validator participation after processing $14 billion in trading.
Orbs rolled out its V5 upgrade on Ethereum and Arbitrum on June 3, 2026. The update is designed to lower cross-chain verification costs, reduce infrastructure overhead and increase validator participation for on-chain trading. The company reported its execution layer processed more than $14 billion in trading volume across over 30 decentralized exchange integrations on more than 10 networks since the V4 release.
V5 introduces a Committee Sync mechanism that propagates authoritative Layer 3 committee state across EVM-compatible chains using signatures collected from the Orbs Guardian network. Under the design, executors generate signed actions off-chain. Guardians verify those signatures and the resulting data is propagated to destination chains, where smart contracts verify actions locally against Guardian signatures and on-chain registry rules.
Orbs indicated that no user funds are moved during synchronization and that only signed state data is transmitted. The company says the approach removes the need for centralized custody or liquidity lockups during verification. Deployed smart contracts will synchronize committee state, propagate nonces and verify signatures on-chain through a dedicated subnet.
The upgrade is live on Ethereum and Arbitrum. Orbs plans to extend V5 support to Base, Polygon, BNB Chain, Avalanche, Linea, Sonic, Berachain and Monad in the coming months. Planned follow-up work includes subnet expansion, signature persistence, historical state replay and updated Guardian node software.
The company stated that all existing products will remain operational during the migration and that users and ecosystem partners should not experience service disruption. Orbs develops Layer 3 infrastructure focused on on-chain trading; its execution layer powers dTWAP, dLIMIT, Liquidity Hub, Perpetual Hub, dSLTP and Orbs Agentic. Since V4, the execution layer generated more than $3.2 million in protocol revenue, the company reported.
Ran Hammer, vice president of business development at Orbs, described V5 as “the next step in our mission… It allows fast, reliable and secure on-chain trading.” He said new products such as Orbs Agentic expand automated trading capabilities and that the V5 design aims to make execution more decentralized, efficient and scalable across chains.
