Arbitrum (ARB) Elara Upgrade Raises Stylus Contract Capacity to 96KB
Arbitrum’s ArbOS 61 Elara upgrade is live, lifting Stylus contract limits to 96KB and adding optional compliance filters for appchains.
AI SummaryAI
- Arbitrum activated the ArbOS 61 Elara upgrade on Aug. 21, raising Stylus contract capacity on Arbitrum One from 24 KB to 96 KB.
- The upgrade gives appchains optional regulatory compliance filters and priority-fee tools, while Arbitrum One and Nova did not enable them.
- Offchain Labs can adjust Arbitrum One’s minimum L2 base fee only within a 0.01–0.10 gwei range authorized by the Arbitrum DAO.
- Node operators must update to at least Nitro v3.11.3 to remain synchronized after the ArbOS 61 activation.
Arbitrum (ARB) has activated the ArbOS 61 “Elara” upgrade, raising the Stylus smart-contract code-size limit on Arbitrum One from 24 KB to 96 KB. The network said the upgrade went live at 02:00 KST on Aug. 21 and effectively separates the feature set of public chains from that of dedicated appchains. For appchains, the protocol now offers an optional regulatory compliance filter, a user-defined priority-fee mechanism, and an alternative data-availability API. The compliance filter attaches an external compliance service to the chain, allowing the chain owner to define address-level policies and screen restricted-address transactions before execution. Those policy tools were not switched on for Arbitrum One or Nova; the team said the filter is a choice for appchain operators that carry regulatory obligations, not a network-wide measure. The main public-chain change is primarily developer-facing. Stylus, the AltVM execution environment that lets developers write smart contracts in Rust and other non-Solidity languages, can now handle larger programs without splitting them across multiple contracts. The size increase applies only to Stylus contracts and leaves Solidity and EVM contract-size rules completely untouched. Arbitrum One also introduced a revised base-fee mechanism through the BaseFeeManager contract, enabling Offchain Labs to adjust the minimum L2 base fee within a 0.01–0.10 gwei range authorized by the Arbitrum DAO. The team said this does not imply automatic fee increases, and the adjustment authority expires two years after mainnet activation. The priority-fee tool remains limited to appchains; enabling it on public chains would require a separate governance vote. Node operators were told to update to at least Nitro v3.11.3 to remain fully in sync. In the amended governance proposal, developers wrote that the gas-refund issue found during Sepolia testing touched the state-transition function and therefore required a new version; Arbitrum One and Nova had never activated ArbOS 60 and were not affected.
Separately, Arbitrum is deepening its real-world asset footprint. Loaf Markets, a platform building on the network, says it wants to make physical assets programmable and tradable on-chain, rather than merely issuing a digital representation. The project is targeting use cases from AI and data-infrastructure ventures such as Terafab to symbolic physical landmarks like the Eiffel Tower and Golden Gate Bridge. The platform argues that programmable assets create new efficiencies in ownership and transactions, and that physical infrastructure should be able to participate in digital markets. By using Arbitrum’s liquidity and blockchain rails, Loaf Markets expects to turn illiquid physical assets into markets that can operate around the clock, with ownership, payment flows, and transaction conditions encoded in contracts. This goes beyond simple tokenization by making the asset itself a live market participant rather than a static digital twin. The project says liquidity is the key unlock for otherwise illiquid assets. Arbitrum’s own data sharing highlighted the project as part of a broader push to expand tokenization activity on the network. This tokenization push comes as the altcoin shows early signs of a technical turnaround and renewed buying interest. Market data from the latest daily session put ARB at $0.09516, up 6.85% over 24 hours, with about $130.07 million in trading volume and a roughly $635.85 million market capitalization. Analysts who follow the token pointed to a double-bottom pattern, noting that buyers defended $0.07 support twice and that a daily close above $0.10 would confirm a trend-reversal setup. In that scenario, the measured advance would open a target between $0.13 and $0.14. The live spot feed shows the token has extended the move, with a 24-hour gain of about 8%. The combination of a constructive price structure and expanding tokenization use cases suggests Arbitrum is attracting attention on both the trading and utility sides.
The common thread is positioning Arbitrum (ARB) as infrastructure that can serve both permissioned institutional use and open, tokenized markets. The primary-source record supports that framing: the adopted proposal text on the Arbitrum DAO forum, last revised June 19, says the ArbOS 61 version was needed because a gas-refund bug found in Sepolia testing touched the state-transition function. The text also limits base-fee adjustments to the 0.01–0.10 gwei range and sets a two-year expiry on Offchain Labs’ authority. Those parameters bind node operators and the protocol’s fee manager, not token holders at large. In our reading, the governance text is deliberately narrow: optional compliance filters for appchains, broader developer tools for public chains, and no change to token issuance.
