Layer 2
A network that processes transactions off a layer-1 chain and settles the results back to it, inheriting its security at lower cost.
Arbitrum, Base and Optimism are Ethereum layer 2s: they batch thousands of transactions, post a compressed record to Ethereum, and charge a fraction of mainnet gas. Assets move between layers through bridges. Coinmico indexes DEX swaps on the layer 2s it covers alongside layer 1s.
