ETH-native creditinfrastructure.
Unlock liquidity from ETH without selling it. Expand wstETH utility. Build long-term Ethereum credit infrastructure. LegacyStack is non-custodial vault infrastructure for ETH and WBTC borrowing — with wstETH-productive collateral on the build path and inheritance-aware ownership built in.
ETH and WBTC holders face a bad tradeoff: sell the asset, use centralized credit, or take on complex, trader-oriented DeFi positions. Long-term holders and institutions need a simpler way to access liquidity while keeping exposure — and existing lending UX, built for short-term traders, keeps them out.
Long-term collateral vaults: deposit ETH or WBTC, borrow overcollateralized OCT, manage collateral health, and configure continuity rules — heir wallets, inactivity windows, and auto-repay logic. wstETH becomes more than a passive staking wrapper: it becomes productive long-term collateral.
Why this matters for Lido
LegacyStack turns wstETH into productive, long-duration collateral. Instead of sitting as a passive staking wrapper, staked ETH backs multi-year vaults — borrowing, auto-repay routing, and inheritance-aware ownership create sticky, non-speculative wstETH demand.
- A new use case: wstETH as long-duration collateral, not just yield exposure
- Encourages holders to stake ETH instead of leaving it idle in wallets
- Yield accounting routes a protocol share into system reserves — staked ETH as financial infrastructure
- LEGO-ready proposal available: purpose, timelines, deliverables, and expense estimates on request
Why Base is a natural launch environment
Vault creation, borrowing, repayments, and inheritance check-ins are exactly the kind of measurable, retail-friendly onchain activity Base rewards. Deployment costs make long-term vault management viable for smaller holders.
- Low-cost UX for vault operations — viable for non-whale users
- Measurable impact: vaults opened, collateral locked, OCT borrowed, heirs configured
- Build-in-public: open repo, docs, demo, and regular build updates
- Testnet demo first, contracts deployment plan to follow — shipped work over promises
What we're open-sourcing
The core protocol is a GPL-3.0 Liquity-derived CDP system. The continuity layer — permissionless, on-chain inheritance with inactivity windows and pre-funded reserves — is infrastructure any Ethereum project can study, fork, and build on.
- GPL-3.0 protocol core with documented deltas from upstream Liquity
- InheritanceManager: a standalone continuity module — heirs, allocations, proof-of-life
- Public runbooks: oracle hardening, liquidation keepers, soak testing methodology
- Expands Ethereum's financial utility beyond trading — self-custody that survives its owner
Institutional continuity for wrapped Bitcoin
WBTC is first-class collateral in LegacyStack. For custody providers and institutional desks, the inheritance layer answers a question clients actually ask: what happens to on-chain positions when the keyholder is gone?
- WBTC vaults with the same borrowing, liquidation, and continuity guarantees as ETH
- Inheritance logic as a service layer for custodial and semi-custodial clients
- Deterministic, auditable succession — no legal limbo for on-chain estates
- Open to integration conversations as the protocol approaches mainnet
Bootstrap liquidity partners
Beyond grants, LegacyStack is raising seed liquidity for the OCT/USDC pair, the Stability Pool, and the redemption buffer — targeting $250k+ with strict caps if the raise lands lighter. Partners earn from real usage: trading fees, liquidation gains, and planned STACK incentives.
