bsc.news reports that the Arbitrum Foundation has launched the Arbitrum Security Program (ASP) to subsidize smart contract audits for ecosystem projects. The initiative commits approximately $7.8 million, comprising 1.76 million USDC and 25 million $ARB, to protect the network. This program evolves the earlier Arbitrum Audit Program, which began in August 2025, by adding AI-assisted screening and a dedicated Security Council.
It covers applications on testnet, mainnet, migrations from other chains, and exclusive Arbitrum chains. Approved auditing firms include OpenZeppelin, Trail of Bits, Cyfrin, and Nethermind. Projects must typically pay a portion of the audit costs alongside the Foundation's subsidy.
The move aims to reduce funding barriers for early-stage teams and ensure audit readiness. Arbitrum remains a leading Ethereum Layer 2 network, competing for builders using Stylus or Orbit custom chains.
How the market reacted
Whalio's own Binance spot order flow for ARB, measured when this story was written up on 30 September 2026. Not the outlet's figures.
Whalio spot data shows ARB trading at $0.2035 with a 1-hour buy ratio of 67.2%, indicating strong immediate buying pressure. This contrasts with the 4-hour buy ratio of 50.8% and the 24-hour ratio of 50.7%, suggesting the recent surge in buying is a short-term spike rather than a sustained trend. The 1-hour volume delta is positive at $342,620, while the 24-hour delta stands at $391,903. The cumulative volume delta for the 24-hour period closes at +$1,068,760, reflecting net inflows. Buying pressure appears to be building in the immediate term but has faded over the longer 24-hour window.
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 average buy ratio was 49.0%, making the current 24-hour ratio of 50.7% slightly above normal by 1.6 points. However, the 24-hour spot volume of $27,439,833 is only 0.77 times the weekly average, indicating lower than usual trading activity. The weekly volume delta was negative at -$3,694,718, and price dropped 13.5% over eight days. This suggests that despite the short-term buy spike, the broader weekly trend remains bearish with net outflows and declining volume compared to the average day.
