Arbitrum (ARB)

dev.to reports that Ethereum account abstraction is moving from specification to active testing, with the ethrex team confirming the EIP-8141 frames testnet has been live for 14 days. Three independent clients, including Geth and Nethermind, are now validating the network, which has processed nearly 400 frame transactions from 21 distinct senders. The team stated the network is ready to move to an interop devnet as tooling catches up to the protocol.
Two supporting proposals, EIP-8250 and EIP-8272, advanced to Considered for Inclusion for Hegotá to support shared-sender privacy. A new draft, ERC-8427, defines a portable spend grant allowing agents to spend up to a set amount of specific assets with a trailing window to prevent loopholes. Safe made contracts v1.5.0 the default for new wallets, introducing stricter signature checks and module guards to close security gaps.
Arbitrum replaced its Timeboost policy with Priority Gas Auctions on Arbitrum One, allowing users to compete for execution via standard EIP-1559 fees. Each 250-millisecond block now contains two 125-millisecond rounds where transactions are ordered by priority fee. The revenue from these fees flows to the ArbitrumDAO treasury, while a companion Fast Feed provides real-time sequencer data to subscribers.
How the market reacted
Whalio's own Binance spot order flow for ARB, measured when this story was written up on 1 October 2026. Not the outlet's figures.
ARB is trading at $0.2029 with a 1-hour buy ratio of 53.3% and a 4-hour buy ratio of 52.4%, indicating short-term buying pressure is currently dominant. This contrasts with the 24-hour buy ratio of 49.9%, suggesting that recent buying intensity is higher than the average pace over the last day. Volume deltas show a net inflow of +$26,244 in the last hour and +$123,287 over four hours, while the 24-hour delta is -$21,312. The Cumulative Volume Delta closed at -$277,972 over 24 hours, meaning that despite recent short-term inflows, sellers have dominated the broader daily flow. Net buying occurred for 11 of the last 24 hours, with a total spot volume of $18,412,094 recorded. This activity reflects a mix of short-term accumulation against a backdrop of daily net selling.
The latest daily buy ratio of 52.1% sits at the 85th percentile of the last 323 days, against a median of 49.6% - stronger buying than most days.
Was that an ordinary day?
The same Binance spot measurements for ARB, averaged over the days leading up to the story.
Over the preceding week, the buy ratio averaged 49.2%, making today's 24-hour ratio of 49.9% only marginally higher by 0.8 points. Volume activity has been subdued, with today's volume at 0.54x the weekly average, indicating lower participation than usual. Net buying was recorded for just 1 of the last 7 days, highlighting a generally passive market structure. The price has declined by 6.1% over the past 8 days, with a total volume delta of -$3,671,023. This recent short-term buying spike is an unusual deviation from the consistent net outflow seen over the longer weekly period.
