Orbs Network has launched the V5 upgrade on the Ethereum and Arbitrum networks, adopting a hybrid Layer 3 architecture. This architecture aims to move the complex execution logic of decentralized finance (DeFi) off-chain, with verification processes installed on two of the most liquid settlement layers in the software ecosystem.
The structural mechanism here is based on a specific principle: instead of running independent validation contracts on each network, Orbs V5 propagates committee state across Ethereum Virtual Machine (EVM)-enabled chains using guardian signatures. This approach eliminates the costs and fragmentation that made on-chain verification economically prohibitive at scale.
Since V4, Orbs has processed over $14 billion in volume across 30+ DEX integrations and generated over $3.2 million in protocol revenue.

This upgrade raises a fundamental question as to whether the hybrid Layer 3 execution model can become the default infrastructure for DeFi automation, or whether it will remain a niche solution for a subset of complex order types.
The deployment targets DeFi automation use cases, namely dTWAP, dLIMIT, Liquidity Hub, Perpetual Hub and dSLTP, as well as the new Orbs Agentic. These tools require implementation logic that is too expensive or technically constrained to run directly on Ethereum or Arbitrum.
Since the launch of V4, Orbs’ execution layer has processed over $14 billion in transaction volume across over 30 decentralized exchange (DEX) integrations across over 10 blockchain networks, generating over $3.2 million in revenue for the protocol.
Committee Sync: How does Layer 3 architecture work and why are Ethereum and Arbitrum the pillars?
The architecture works as follows: Orbs executors execute off-chain trading logic, including evaluating order conditions, routing decisions, and execution triggers, and then generate signed actions that are sent to the Guardian network for verification. These signed actions, along with the approved state from the layer 3 committee, are then transmitted to target chains where smart contracts deployed there verify them locally using custodian signatures and on-chain logging rules. This process is known as Committee Sync: a single source of truth for the Commission that emanates from Orbs L3 and is transmitted to each supported EVM chain via a signature-based relay rather than a separate consensus process on each network.
Ethereum and Arbitrum constitute the main security pillars of this model, where the state of the root committee is fixed and from which cross-chain publishing follows. This design places the orbs in the same structural space occupied by layer 2 expansion solutions, but they operate in a separate layer; Instead of aggregating user transactions on a single chain, Orbs keeps execution logic on specialized off-chain nodes and uses a smart contract extension to enforce settlement rules on target decentralized exchanges without the need to hold user funds in software bridges. Under this design, only signed state data passes through the protocol during sync and user funds are not transferred, completely eliminating retention risks from the cross-chain verification process.
The critical variable for DeFi automation is not off-chain execution itself, this model has become stable and well known. Rather, the challenge lies in the extent to which the cost of on-chain verification can be reduced to make advanced order types such as dTWAP and dLIMIT economically competitive with centralized alternatives in each chain on which the protocol runs. The Committee Sync feature in V5 is a direct structural response to this cost pressure issue.
Multi-chain deployment scope: eight additional EVMs
V5 is currently available on Ethereum and Arbitrum and is expected to expand to Base, Polygon, BNB Chain, Avalanche, Linea, Sonic, Berachain and Monad in later stages. This map reflects a deliberate strategy, targeting networks where DeFi transaction volumes are concentrated, where the takeover of Ethereum as a settlement layer is spread across Layer 2 and alternative networks, and where fragmented liquidity creates high demand for cross-chain execution infrastructure.
