DeFi Got Cheaper and Faster, and Complicated
$ARB is Ethereum's largest L2 by TVL, $16 billion locked, OP $OP is scaling the Superchain, building the infrastructure for an interconnected network of low-fee chains that moves value across Ethereum's ecosystem without the friction.
Both solved the cost problem. The complexity problem is still open.
Using DeFi on any chain, even a fast, cheap one, still means setting gas, choosing slippage tolerance, picking a liquidity route, and hoping the conditions you locked in are still valid by the time the transaction lands. That's not a user experience.
That's a cockpit with no training.
The billions sitting in ARB and OP ecosystems aren't waiting for cheaper transactions.
They're waiting for DeFi that behaves more like a bank transfer and less like a command line.
Reactive Contracts move toward that world.
