## When to use
Use this skill when you are:
- Fetching Ethena sUSDe spot APY (derived from the vault’s vesting model)
- Reading a user’s USDe/sUSDe balances and cooldown state (mainnet + OFT balances on other EVM chains)
- Writing scripts to stake USDe (deposit) or withdraw via the two-step cooldown + unstake flow
## How to use
- [rules/high-value-reads.md](rules/high-value-reads.md) - APY, cooldown, and user state
- [rules/execution-opportunities.md](rules/execution-opportunities.md) - Deposit + request-withdraw + claim-withdraw flows
- [rules/gotchas.md](rules/gotchas.md) - Mainnet-only vault, two-step withdrawals, and return formats
