PensionStrategy: A Transparent, Efficient, and Adaptive Onchain Pension Vault
PensionStrategy is an ERC-4626 vault that reimagines retirement savings on Ethereum by combining long-term vesting, yield donation, transparent asset allocation, and low, fair fees — all in a single, auditable smart contract.
The Problem It Solves
Traditional pension systems and even many DeFi yield strategies suffer from three core issues:
Administrative fees dominate costs.
Asset allocation is opaque.
Change is slow.
These pain points erode returns, hide risk, and prevent adaptation to new opportunities.
How PensionStrategy Solves It
| Problem | Solution with PensionStrategy |
|---|---|
| Administrative fees dominate costs | Only 1% fee on yield (not principal)<br>→ Management fee (managementFeeBPS = 100) is taken only from generated yield, never touching user deposits. <br>→ No hidden fees, no performance drag on capital. |
| Asset allocation is opaque | 100% onchain, real-time visibility<br>→ Funds are split 50/50 between Aave (sDAI) and Yearn (sUSDS) — both battle-tested, audited ERC-4626 vaults.<br>→ totalAssets() shows exact breakdown of idle + vault holdings.<br>→ All logic is open-source and verifiable. |
| Change is slow | Owner can switch assets instantly<br>→ switchAsset() allows seamless migration (e.g., DAI → USDS) without user action.<br>→ Approvals are updated, funds rebalanced — all in one transaction.<br>→ Future-proof: adapt to better yields or safer protocols in real time. |
What Can People Use It For?
1. Long-Term Retirement Savings
- Lock in DAI for 30 years (360 months).
- Monthly pension claims auto-vest: principal + proportional yield.
- No early withdrawal before
MIN_LOCK_PERIOD(30 days) — enforces discipline.
2. Beneficiary Protection
- Set a beneficiary who can claim all shares if you’re inactive for 365 days.
- Ideal for estate planning or digital legacy.
3. Yield Donation for Social Good
- All excess yield (after user claims and 1% fee) is donated via
harvestAndReport(). - Default: Gitcoin multisig (
0xde21...) — funds public goods. - Win-win: users earn, builders get funded.
4. Transparent, Auditable Yield Farming
- No black boxes. No "strategy manager" opacity.
- See exactly where your money is: Aave + Yearn.
- Upgradeable allocation via
switchAsset().
Use Cases
- A freelancer locks 10,000 DAI for retirement
- A DAO allocates treasury to long-term growth + public goods
- A family sets up a trust with beneficiary fallback
- A protocol donates yield to Gitcoin automatically
