Uniswap: Arc Tops $300M in Swaps Since Launch

Uniswap says Arc has surpassed $300 million in swaps

In a September 20, 2026 post on X, Uniswap said more than $300 million had been swapped on Arc since launch. The same announcement noted that Uniswap represented 84% of all DEX volume on the chain, positioning it as the overwhelmingly dominant liquidity venue on Arc from day one.

Arc is described on its official site as an EVM-compatible Layer-1 with stablecoins as native gas, a design that removes the typical friction of holding a volatile gas token to interact with DeFi protocols. That architecture makes it a natural fit for Uniswap’s swap-heavy user base. For related coverage, see Mellow Protocol TVL Hits $300M as Liquid Restaking Airdrop Buzz Builds.

Live data from DeFiLlama’s Arc DEX tracker puts all-time Arc DEX volume at approximately $370.8 million at retrieval, a figure that reflects activity beyond the announcement cutoff and therefore cannot be used to reconstruct Uniswap’s exact historical 84% share. That live snapshot does break down Uniswap’s on-chain volume across protocol versions: Uniswap V2 accounts for roughly $25.1 million, V3 for $122.7 million, and V4 for $205.9 million of the cumulative Arc total.

The V4 dominance within that breakdown is notable. Uniswap V4’s hooks architecture allows liquidity pools to be customized with protocol-level logic, and its outsized share on Arc suggests that deployers are actively leveraging that flexibility rather than simply porting legacy V2 or V3 pools.

What the Arc volume milestone signals for early adoption

Cumulative swap volume is a directional signal, not a comprehensive protocol health metric. It measures transaction throughput since genesis but says nothing about liquidity depth, the number of unique addresses, repeat swap behavior, or fee revenue generated for liquidity providers. An early $300 million figure on a newly launched chain is consistent with bootstrapping activity, where concentrated initial users drive high notional volume before broader retention is established.

Volume as a one-dimensional metric

Protocol analysts typically triangulate volume against TVL and fee yield before drawing adoption conclusions. DeFiLlama reports current Uniswap TVL on Arc at approximately $24.4 million, which implies a volume-to-TVL ratio that points to active pool utilization rather than idle liquidity sitting on-chain. That ratio is worth monitoring as the chain matures and new protocols compete for liquidity allocation. Uniswap’s recent activity on other chains, including its proposed fee-burning mechanism on Robinhood Chain, suggests the protocol is actively expanding its multi-chain footprint with tailored governance and fee structures per deployment.

The 84% DEX share Uniswap holds on Arc is high even by its standards on established chains. Whether that concentration persists depends on whether competing AMMs deploy on Arc and attract meaningful liquidity incentive programs. High DEX share in a chain’s early days often compresses as ecosystems mature and fragmentation increases across venues.

What to watch after Arc’s first reported swap milestone

The data points that will clarify traction

The metrics that would put the $300 million figure in proper context are not yet publicly available in aggregated form. Transaction count alongside volume would clarify whether the figure reflects a broad user base or a smaller cohort executing high-value swaps. Repeat wallet activity over rolling 30-day windows would signal retention rather than one-time inflows from incentive programs.

Volume growth rate is the other key variable. A $300 million cumulative figure means something different if it was reached in three weeks versus six months. As Uniswap continues expanding across new deployments, including its Pons token acquisition for long-term alignment, its Arc deployment adds another data point in the protocol’s multi-chain liquidity strategy. Fee revenue accruing to LPs on Arc, and whether that yield is competitive with other Uniswap deployments, will ultimately determine whether liquidity providers maintain or deepen their positions on the chain. UNI is currently trading at $8.71, up approximately 0.24% over the prior 24 hours, with a market cap near $5.4 billion.
