Earn yield on any Ethereum wallet on Base, Arbitrum, and Plasma. Use when a user wants passive DeFi yield on their funds. Deploys a non-custodial deterministic subaccount (Safe) linked to their EOA, enables automated yield optimization, and lets them deposit/withdraw anytime.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Zyfai — Yield for Any Wallet Turn any Ethereum wallet into a yield-generating account. ## What This Does When a user wants to **earn yield** on their crypto, Zyfai creates a **deterministic subaccount** (Safe smart wallet) linked to their existing wallet (EOA). Funds deposited into this subaccount are automatically optimized across DeFi protocols. The user stays in full control and can withdraw anytime. ``` ┌─────────────────┐ ┌──────────────────────┐ │ User's EOA │ ───► │ Zyfai Subaccount │ │ (their wallet) │ │ (Safe smart wallet) │ │ │ │ │ │ Owns & controls│ │ • Auto-rebalancing │ │ │ │ • Yield optimization│ │ │ │ • Non-custodial │ └─────────────────┘ └──────────────────────┘ ``` **Key points:** - The subaccount is **owned by the user's EOA** — only they can withdraw - Session keys allow **automated rebalancing** but cannot withdraw to other addresses - Same EOA = same subaccount address across all chains ## The Flow ``` 1. DEPLOY → Create a deterministic subaccount linked to user's wallet 2. SESSION → Enable automated yield optimization …

How to install
mdr add bankrbot/skills/zyfai@sha256:98475444f494c020The line at the top of this page pins the label git:20260317.4db5dc7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
