Cyberk

Cyberk is a development studio for Web3 and AI projects that turns common contract capabilities into a reusable template library: yield vaults follow ERC-4626, account abstraction follows ERC-4337, and subscription billing uses the ERC-2612 approval pattern, so a team composes these pieces to fit a project instead of building from scratch.

Mechanically, templates ship as modular contracts plus an adapter layer that aligns interfaces between standards, for instance letting vault shares support both batched calls from account abstraction and periodic approvals for subscriptions; on the payment side it integrates x402 per-call settlement, and on the agent identity side it follows the ERC-8004 registration and reputation record so a machine call can carry a verifiable identity and payment credential. Its users are protocol teams at the prototype stage and developers building agent applications. The team has published the template list, the dependency graph between modules, and the initialisation order and permission split for a composed deployment.
