Stakr Protocol — Agent Overview

This skill gives agents the context to interact with the Stakr protocol: ERC-4626 tokenized vaults with multi-reward staking for any ERC-20 token. Use it when building integrations, scripts, or tooling that create vaults, add rewards, modify reward schedules, or let an agent operate its "own" vault.

Protocol at a Glance

• StakrVault: Single-asset ERC-4626 vault. Users deposit underlying, get shares; they can lock shares to earn multiple reward tokens over configurable windows.
• StakrVaultFactory: Deploys vaults and holds protocol fee configuration. One factory per chain.
• Rewards: Up to 25 reward tokens per vault. Each reward has startTime, endTime, and total amount. Distribution is linear over the window; logic is Masterchef-style (accumulated rewards per share).
• Ownership: A vault can have an owner (address that can add/modify rewards) or address(0) for permissionless reward addition.

When an agent is said to have its "own vault", it means: the agent (or a controlled EOA/contract) is the vault owner, so it can call addRewardToken and modifyRewardToken to fund and adjust rewards without third-party permission.

Emphasis: Adding and Modifying Rewards (Agent-Owned Vaults)
