About Cometh
This technical demo is developed by the Cometh team for EthCC[7].
Cometh offers an Account Abstraction Kit based on 4337, SAFE and Passkeys which allows you to easily onboard all users.
As Web3 rapidly expands within the diverse landscape of L2 solutions and rollups, Cometh plans to launch the first Account Abstraction solution allowing a seamless and unified user experience across different chains.
About SAFE
Safe Smart Accounts are the most audited and battle-tested. Since 2018, these smart contracts have passed the highest possible security standards in the industry including formal verification.
About Hashi
Hashi is an EVM Hash Oracle Aggregator, designed to facilitate a principled approach to cross-chain bridge security. Hashi is used for dispatch, stores and relaying arbitrary messages.
About LayerZero
LayerZero is a technology that enables applications to move data across blockchains, uniquely supporting censorship-resistant messages and permissionless development through immutable smart contracts.
How it works
A “primary SAFE” deployed on a chain (Optimism in this demo) controls one or more “secondary SAFEs” on other chains. (Arbitrum in this demo).

These secondary safes have a special module (developed by Cometh) that allows them to execute transactions delegated by the Primary SAFE for their network.
