The Hourglass release consists of a framework that supports the creation of task-based AVSs. The task-based AVSs are enabled through a TaskMailbox core contract deployed to all chains that support a CertificateVerifier. Additionally AVSs deploy their TaskAVSRegistrar. The release has 3 components:

1. Core Contracts
2. AVS Contracts
3. Offchain Infrastructure

The below release notes cover Core Contracts. For more information on the end to end protocol, see our docs and core contract docs.

Highlights

This hourglass release only introduces new contracts. As a result, there are no breaking changes or deprecations.

🚀 New Features

Destination Chain Contracts

• TaskMailbox: A core infrastructure contract that enables task-based AVS execution models. It provides a standardized way for AVSs to create tasks, have operators execute them, and submit verified results on-chain. The contract acts as a mailbox system where task creators post tasks with fees, and operators compete to execute and submit results with proper consensus verification.
