Superposition Accounts is a ed25519 smart account server that executes calldata on behalf of the submitter, with a list of goals, permit onramping arguments, and more. The factory looks up the address of the implementation before executing it. Proxies are configured using a metamorphic proxy pattern spun up using the storage slot.

During registration, a user calls the factory contract, which validates the signature and user data. The factory then uses create2 on the Ethereum address to call the migration method, which simply delegatecalls back to the factory.

It's possible to register contract "authorities" for accounts registered. These servers must support the function allowed(address)(bool). These authorities are consulted before executing a transaction to check if the hash of the contract they're calling is whitelisted.

Migrations are possible by the EOA owner of the contract.

Factory -> Client [label="Looks up address"]
AccountServer -> Client [label="Executes the calldata with the goals on this server"]
