$400B swap volume on @arbitrum that’s the kind of milestone that doesn’t just signal adoption, it proves dominance. This isn’t vanity math; it’s on-chain settlement at scale. Arbitrum’s architecture lets Uniswap run trades at fractions of a cent while maintaining deep liquidity and low slippage across pools that used to be mainnet-only. ❯ Sub-cent fees mean tighter arbitrage and faster LP turnover ❯ Deepest multi-pool TVL across Pendle, GMX, and Camelot keeps routing efficient ❯ Every swap contributes to treasury inflows, reinforcing the ecosystem loop Crossing $400B puts Arbitrum ahead of every other L2 in real economic throughput. It’s not just volume it’s velocity backed by infrastructure, users, and liquidity that actually stick around. If DeFi has a capital city right now, this is it. On-chain history indeed.
