Hooklist builder

Create an evidence-backed hook package

Generate a fail-closed Solidity scaffold and versioned manifest. Every selected callback reverts until you implement its policy, and the manifest remains a draft until every deployment and trust declaration is entered and reviewed.

Attach to a task

Custom hooks keep the order entered here. Taskmarket prepends the current protocol defaults when the task is created.

Ordered custom hook addresses

One non-zero address per line or comma. The current protocol supports at most eight defaults plus custom hooks together.

Shared hookData

V1 sends this one byte-string value to checkFund on every custom and default hook. Taskmarket does not support a different hookData value per hook.

Protocol defaults, called first

1. 0x0f40337879fee4074e4f4b77e0de8623b85ca8f7

2 of 8 total hooks after adding 1 custom hook.

CLI attachment command

taskmarket task create --description "..." --reward <usdc> --duration <hours> --hook 0xfc6f92657d29a4f46ff417efef680ec8c5842f89 --hook-data 0x

Publish after independent review

Replace every fail-closed callback stub, download both files, compile the scaffold against the installed contracts package, and run the manifest validator before submitting the repository and deployment evidence through the public listing process.
