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 - APY, cooldown, and user state
• rules/execution-opportunities.md - Deposit + request-withdraw + claim-withdraw flows
• rules/gotchas.md - Mainnet-only vault, two-step withdrawals, and return formats
