Arbitrum One keeps showing why serious projects choose this network as a base layer.

$ERA joins the ecosystem through @Calderaxyz’s Onchain Expansion Program, and I see this as a win for Arbitrum.

ERA now lives natively on @arbitrum One with a canonical token contract and fresh liquidity on Uniswap.

You trade ERA against USDC, USDT, and ETH without leaving your usual Arbitrum flow. For me this matters because real activity follows deep liquidity and low fees.

Here is what you get on Arbitrum today

- Near instant ERA bridging through Caldera’s Metalayer with a single canonical asset across chains

- Permissionless trading on Arbitrum One where many DeFi users already spend time

- A clear path for wallets, bridge aggregators, and apps to plug ERA into daily flows

The program also highlights Arbitrum’s role as a hub for new L2 and L3 ecosystems. As Caldera expands ERA across more environments, Metalayer keeps liquidity connected, which strengthens the broader network.

If you care about onchain activity on Arbitrum, this is a moment to track.

Watch volumes on the ERA pools, watch Metalayer bridge flows, and think about how your own stack might tap into this new liquidity.
