Arbitrum: The Architecture of the Programmable Economy

Global markets still rely on traditional systems where payments pause at borders and innovation moves slowly. Having spent years earning trust, Arbitrum is now evolving from a scaling solution to the finance-native platform powering the programmable economy. As the largest ecosystem on Ethereum with nearly $17B in total value secured, 2.6 billion transactions, and 30+ dedicated blockchains, Arbitrum provides the proven foundation for this borderless, real-time future. 

Building on this foundation, Arbitrum is advancing the architecture to improve operational efficiency and expand global reach, helping businesses implement protocol-level compliance and configure data confidentiality to meet the needs of their category-defining products.*

Here is a look at the architecture being developed to support this next phase of growth:

Stable pricing your users can depend on

Status: Live on Arbitrum One

The programmable economy requires infrastructure built to sustain billions of transactions. If those transaction costs spike unpredictably, payment flows can break and institutional operating models become unreliable. While legacy gas models don’t always align with real-world demand, the Arbitrum Platform addresses this friction through Dynamic Pricing, a first-of-its-kind pricing model that provides businesses:

1. Predictable costs
   Users and operators only pay for what they use on the network. Transactions that require fewer resources no longer subsidize more computationally intensive transactions, making it easier for businesses to forecast costs.
2. Smooth User Experience
   Fewer price surges, fewer dropped/failed submissions, and more confidence that your product behaves predictably when the network is experiencing high demand.
3. Headroom to scale sustainably
   Dedicated blockchains can achieve higher sustained throughput (Arbitrum One has already reached 910 MGas/s on mainnet). This is possible because pricing now accurately reflects the resources that limit performance, preventing node operators from being forced into large hardware upgrades.

Support for regulatory compliance from day one

Status: In development for dedicated blockchains

A programmable economy requires a framework that aligns with the legal mandates of the global financial system. For fintechs, banks, and asset managers, managing regulatory compliance is a prerequisite for entry. By providing tools built to support these obligations natively, the Arbitrum ecosystem aims to help move compliance from a barrier to an operational unlock, lowering the friction for the world’s most significant capital allocators to participate through the following capabilities:

1. Onboard your screening provider
   Onboard with your preferred screening provider and apply your required policies with robust traceability for allow/deny decisions.
2. Configure your restriction list
   Define your KYC, AML, and OFAC parameters from day one. Your dedicated blockchain can be configured to automatically reference your customized lists so that onchain interactions are filtered at the protocol level.
3. Whitelist permitted participants
   Define which users, teams, or counterparties are permitted to interact with the blockchain or specific smart contracts, making it easier to enforce internal access policies across your products.
4. Real-time reporting
   View transactions as they are filtered live, or export records of blocked addresses and transaction activity to support audit trails, internal review, and reporting requirements.

Confidentiality that protects your competitive edge

Status: In development for Arbitrum One (subject to DAO vote) and dedicated blockchains

True scale in a programmable economy requires balancing public transparency with enterprise-grade confidentiality to support real-world markets and institutions. While open ledgers provide unparalleled trust, the involuntary exposure of client balances and proprietary order flow remains a significant barrier to institutional adoption. To address this, the Arbitrum Platform is building a privacy architecture that supports the full spectrum of visibility, from third-party privacy tools for applications on Arbitrum One, to fully private dedicated blockchains for more sensitive operations. Each option is engineered to help businesses safeguard proprietary data and manage strict confidentiality requirements while benefiting from the following architecture:

1. Selective disclosure by design
   Privacy doesn’t mean hiding everything from everyone. It means keeping sensitive activity confidential in the market while still giving approved operators, auditors, regulators, and internal teams the access they need.
2. Three ways to apply privacy
   Privacy is not one model. Some products need confidential applications while operating on a public blockchain. Others require private user interactions with public, EVM-compatible applications. And others need a dedicated blockchain where privacy is built across the entire stack. The Arbitrum Platform is being designed to support all of these models.

Settle capital in near real-time with ZK proofs

Status: In development for Arbitrum One (subject to DAO vote) and dedicated blockchains

We are living in a fast-paced, internet native world and capital cannot afford to be idle or trapped by latency. For global markets to operate at the speed of software, the movement of assets between environments must be near-instant and cryptographically sound. Arbitrum is achieving this by developing Zero-Knowledge (ZK) proving on Succinct's SP1 to reduce settlement from a days-long process to minutes. By layering ZK proofs alongside Fraud Proofs and TEE attestations, businesses will be able to benefit from a multi-prover architecture that maximizes both security and capital velocity, offering:

1. Improved capital efficiency
   Dedicated blockchains already provide settlement in minutes. ZK proofs extend that settlement to native withdrawals, giving Ethereum the cryptographic verification it needs to release assets in hours upon deployment, and minutes as proving matures, freeing capital while minimizing dependence on third-party bridge liquidity.
2. Multi-prover assurance
   Choose the proving setup that fits your risk, cost, and latency targets. ZK can operate alongside TEEs and fraud proofs, reducing reliance on any single mechanism and strengthening security for regulated flows.
3. Privacy at the protocol-level
   Privacy-preserving blockchain deployments where sensitive business data can remain confidential while correctness is still provable. This protects margins, enables you to grow with confidence, comply with privacy compliance rules, and protects users.

New economic levers to scale your business

Status: In development for Arbitrum One (subject to DAO vote) and dedicated blockchains

Modern markets demand infrastructure as flexible as the business models they power. Arbitrum is introducing a suite of economic levers businesses can adjust to meet their specific requirements. Aligning technical architecture with commercial reality is precisely what scales the programmable economy for everyday business.

1. Arbitrum Universal Intents
   This standard is being developed to allow dedicated blockchains to securely facilitate transfers and swaps between networks including Ethereum, Layer 2s, Solana, Hyperledger, Canton, and more.
2. Yield-Bearing Bridge
   Dedicated blockchains will gain the capability to optimize idle bridge reserves, allowing ecosystems to route captured efficiencies toward liquidity incentives, fee subsidies, or protocol operations.
3. Priority Gas Auctions (PGA)*
   A new ordering policy to give high-frequency traders 125ms pre-confirmation cycles and more transparency. Importantly, the increase in gas auctions can capture additional revenue to Arbitrum One (subject to DAO approval) or related dedicated blockchains without introducing structural fee increases for everyday users.
4. Real-Time Sequencer Feeds
   A new sequencer enhancement will provide a ~125ms feed of transaction ordering data prior to block finalization. This allows for fast "soft-confirmations," significantly reducing latency for high-precision users. By offering real-time market visibility, we empower those requiring millisecond accuracy without compromising the low-cost, user-friendly environment the broader community expects.

The next generation of finance will be programmable

In 2026, Arbitrum is focused on building the best tech to support category-defining products in this new world. Predictable unit economics. Control over execution. Fast settlement. All of it builds toward one outcome: a global, programmable economy.
