Lido Skill (Operational)

Core Assets

• stETH: rebasing token representing staked ETH.
• wstETH: non-rebasing wrapper around stETH.

Rebase Model

• stETH balance rebases over time.
• wstETH balance stays fixed; value vs stETH changes via conversion rate.

Treasury Accounting Rule

• Hold treasury in wstETH.
• Track principal in stETH-equivalent units with getStETHByWstETH.
• Available yield = current stETH-equivalent value - principal baseline - reserved.
• Agents spend only yield, never principal.

Safe Staking Patterns

1. Stake ETH -> stETH.
2. Wrap stETH -> wstETH for deterministic treasury accounting.
3. Use dry-run before all writes.

Withdrawal Pattern

1. request_unstake (creates withdrawal request/NFT state).
2. Wait for finalization.
3. claim_unstaked.

Earn Basics

• Monitor supports EarnETH and EarnUSD (and EarnUSDc helper path).
• Compare vault APR against raw stETH APR benchmark.
• Watch allocation shifts across Aave/Morpho/Pendle/Gearbox/Maple when present.

Governance Basics

• List votes/proposals.
• Read vote details.
• Delegate voting power.
• Vote casting is optional and permission-dependent.

Chain Policy

• Trust domain: Sepolia only.
• Execution domain: mainnet fork by default, optional mainnet live.
• Never conflate trust-chain verification with execution-chain tx confirmation.

Pre-Write Checklist

1. Is this action a write?
2. Has dry-run passed?
3. Is recipient trusted/whitelisted?
4. Will principal floor remain intact?
5. Are per-tx/window/sub-agent limits satisfied?
6. Are chain labels correct in output?

Decision Heuristics

• If intent is uncertain, choose read-only path first.
• For governance actions, default to delegation dry-run.
• For treasury spends, always preview before execute.
• If monitor data feed is stale/unavailable, communicate uncertainty and avoid risky writes.
