ARB gains more than 30%

Arbitrum’s ARB token traded at approximately $0.2133 at the time of the check. Its 24-hour trading volume reached $749.3 million, while its market capitalization stood at roughly $1.45 billion.

ARB traded between $0.1617 and $0.2286 over the same period. Although its latest price remained below the top of that range, the token retained strong daily gains.

The rally also lifted its weekly performance. Market data showed that ARB gained 51.4% over the past seven days, extending the recovery seen in previous sessions.

Among ARB, UNI and STRK, ARB delivered the highest 24-hour return. However, its trading range also showed that substantial price fluctuations continued throughout the period.

UNI trading volume exceeds $2 billion

Uniswap’s UNI token rose to approximately $8.62. Its 24-hour trading volume reached $2.23 billion, while its market capitalization stood at around $5.35 billion.

UNI traded between $6.91 and $9.39 over the same period. At the time of writing, it remained below its highest price during that window but still recorded a gain of nearly 25%.

These figures placed UNI among the day’s notable altcoins in terms of both price performance and trading activity. Trading volume measures the total value of trades; it does not, on its own, indicate net capital inflows.

Starknet’s STRK token also joined the rally. Trading at approximately $0.03374, the token gained 20.4% over the previous 24 hours.

STRK’s trading volume reached $75.8 million, while its market capitalization stood at $247.7 million. The token traded within a range of $0.02752 to $0.03635 during the same period.

Gains spread across the broader market

According to CoinDesk’s September 18 market assessment, the recovery was particularly strong among decentralized finance and layer-2 tokens. The report noted that 98 of the 100 assets in the CoinDesk 100 index were trading higher on the day.

The decline in the US 10-year Treasury yield below 5% was among the macroeconomic developments accompanying the recovery. Brent crude’s retreat below $103 also helped ease inflation concerns following the Federal Reserve’s interest rate increase.

Altcoins outperform as Bitcoin rises

While Bitcoin gained approximately 2%, advances exceeding 20% in ARB, UNI and STRK highlighted the stronger moves in these three tokens. Bitcoin’s 24-hour trading volume stood at roughly $29.74 billion.

At the time of the check, all three altcoins traded below their respective 24-hour highs. Despite their strong gains, prices had pulled back from the highest levels reached during the period.
