Robinhood Chain's DEX volume declined last week, falling 24 percent from $2.1 billion to $1.6 billion—a sharp cooling after its rapid initial growth on the Arbitrum-based network.

The chain launched with significant momentum, recording $3.1 billion in DEX trades during its first week and briefly ranking among the top five networks by volume. More than 65,000 users joined its tokenized asset platform during that period.

Daily DEX volume averaged $553 million last week, a 27 percent decline from the prior week's average. Daily volume had previously peaked at $878 million before dropping to $440 million—a near 50 percent reduction from its high—before a partial rebound to $638 million.

The chain's turnover ratio, calculated by dividing DEX volume by TVL, fell from 9.25x in its second week of July to 1.68x by last Friday, reflecting how much less frequently deposited capital is being traded.

Deposits have continued to flow in despite the trading slowdown. Robinhood Chain's TVL climbed to $332 million in less than a month, indicating users are still bridging assets even as volume contracts.

The initial volume surge was driven largely by memecoin trading, which has since subsided. Tokenized stocks and real-world assets—a stated focus for the network—have not stepped in as volume drivers, with activity in those categories remaining low.

Robinhood has not introduced sustained long-term incentives to retain engagement beyond the launch window, and the platform has not converted its large retail user base into consistent on-chain traders on its dedicated chain.

Sustaining volume will depend on whether the chain can build a consistent trading ecosystem around tokenized assets or other DeFi primitives that attract and retain liquidity.
