We can argue zk proofs or sequencer models all day, but money already made its choice.

Cheaper, faster; those come and go and then what always stick is gravity & right now, it lives on @arbitrum.

Ethereum’s L2 landscape has matured into a liquidity hierarchy.

The scaling question is solved; the real contest now is who anchors capital.

By bridge type, @arbitrum holds $17.05B, followed by @base $15.26B.

Then a sharp drop: @Optimism $2.96B, @LineaBuild $1.37B, and @Starknet $706M

Half of Ethereum’s L2 liquidity sits inside just two systems, but only one monetizes it natively through composable DeFi depth. That’s @arbitrum's edge: liquidity that earns, trades, and recycles without leaving orbit.

Liquidity behaves like a gravity well. Once a network passes a certain mass, every inflow bends toward it. Depth tightens spreads, lowers slippage, reinforces retention, and the loop repeats.

@GMX_IO, and @CamelotDEX formed the yield base that kept leverage and liquidity on-chain.

Capital → volume → fee stability → builders → more capital.

The sequencer made it mechanical.

@arbitrum runs 15–20 TPS with predictable finality; nearly twice Optimism’s realized rate.

Reliability compounds invisibly, and with Ethereum’s Fusaka upgrade expected to cut DA costs by 30%, sequencer margins expand further.

Its moat now rests on three layers:

➤ Liquidity density: deep collateral markets.

➤ Composability: Orbit chains and Stylus extensions without fragmentation.

➤ Credibility: RWA and restaked $ETH using it as a base.

@Optimism leans on governance unity, @base on retail funnels.

@arbitrum does what matters most: makes liquidity stay.

Velocity is the moat. Capital moves efficiently inside its walls and rarely leaves. Volume feeds reliability, reliability feeds trust, and that trust keeps the loop spinning.

Layer 2s aren’t competing on tech anymore, they’re competing on gravity. And that center of mass is still @arbitrum.
