A network built on top of a base blockchain that processes transactions separately and periodically writes a compressed proof back to the main chain, inheriting its security at a fraction of the cost.
Layer 2 is what makes on-chain products usable for ordinary amounts: fees drop from dollars to cents and confirmation takes seconds, without giving up the guarantees of the underlying network.
We choose the network by where your users and liquidity already are, account for bridging in the user journey, and design so the product can support several networks rather than being welded to one.
