Refresh cash-equivalent reserve APY from Aave and USTB (cron)

Expected schedule: every 5 minutes.

Loads all cash equivalent reserves, then refreshes APY by yieldSource for rows whose JSON data has cashEquivalentType on-chain:

  • Aave (yieldSource Aave): reads Aave V3 USDC liquidityRate on Base mainnet via Alchemy (API key from ALCHEMY_RPC_KEY), derives compounded supply APY (annual rate in ray, same compounding model as Aave MathUtils).
  • USTB (yieldSource USTB): reads 30-day yield from the Superstate API (https://api.superstate.com/v1/funds/1/yield); result is cached in memory for 24 hours under ustbYield so the external call runs at most once per day.

Matching reserves get apy updated; others are skipped. Returns 204 with an empty body on success. Requires X-CRON-API-KEY matching CRON_API_KEY.
