Arbitrum has returned to the center of the altcoin conversation after ARB climbed more than 40% over two days. The move coincides with the fifth anniversary of Arbitrum One, which launched in 2021 and now hosts more than 1,100 teams developing programmable financial products.
Key ecosystem metrics support the rally. Tokenized stocks on Arbitrum One recently reached a record $200 million market cap. Across Arbitrum One and Robinhood Chain, tokenized stocks reached $227 million. Arbitrum One recorded more than $100 million in stablecoin inflows in 24 hours, while the broader Arbitrum platform reported nearly $50 million in tokenized stocks, ETFs, and commodities on Robinhood Chain.
Robinhood Chain has become a direct economic link to Arbitrum. It passed $1 billion in total value locked and generated more than $6 million in total revenue. In one 24-hour period, Robinhood Chain produced more than $1 million in fees. As a dedicated Arbitrum chain, 10% of its net protocol revenue flows back to the Arbitrum ecosystem.
The ArbOS 61 Elara upgrade has also expanded Stylus smart contract capabilities by 4 times and introduced adjustable minimum base fees. Meanwhile, PayPal's PYUSD stablecoin is now available to eligible Venmo users for buying, selling, sending, and using on Arbitrum.
On-chain data showed three consecutive days of large net ARB withdrawals from centralized exchanges, reducing immediate sell-side liquidity. However, risks remain. Researchers noted that up to 99.1% of the sudden reported volume increase showed characteristics associated with wash trading. Arbitrum is also scheduled to unlock 92.63 million ARB tokens on September 16, valued at roughly $8.9 million.
Technically, ARB needs to clear resistance around $0.117 to target $0.13. Failure could see support tested at $0.10 and then $0.09. DeFi researcher Ignas urged caution on how much Robinhood Chain's success ultimately benefits ARB, while commentator Immortal argued Arbitrum remains stronger than many Layer 1 networks based on rising active addresses, real-world assets, and stablecoin liquidity.
