Clones

https://eips.ethereum.org/EIPS/eip-1167 is a standard for deploying minimal proxy contracts, also known as "clones". > To simply and cheaply clone contract functionality in an immutable way, this standard specifies > a minimal bytecode implementation that delegates all calls to a known, fixed address. The library includes functions to deploy a proxy using either create (traditional deployment) or create2 (salted deterministic deployment). It also includes functions to predict the addresses of clones deployed using the deterministic method. Available since v3.4.**
