 ## Goals
 
-It should be possible to efficiently locate the Serai Router on an blockchain with the EVM, without
-relying on any centralized (or even federated) entities. While deploying and locating an instance of
-the Router would be trivial, by using a fixed signature for the deployment transaction, the Router

 ## Methodology
 
-We define a contract, the Deployer, to deploy the router. This contract could use `CREATE2` with the
-key representing Serai as the salt, yet this would be open to collision attacks with just 2**80
-complexity. Instead, we use `CREATE` which would require 2**80 on-chain transactions (infeasible) to
