Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aave

  • Bridge and cross-chain vulnerabilities expose protocols to external risks, as demonstrated by 2026 rsETH exploit
  • Oracle dependency creates liquidation risk if price feeds fail or experience flash loan attacks
  • Liquidation mechanics require users to manage collateral ratios actively or face full position closure

Etherscan

  • The free API plan is capped at 3 calls per second and 100,000 calls per day
  • The free plan requires attribution and covers only selected chains rather than all supported chains
  • API Pro endpoints are withheld below the Standard plan at $199 per month
  • The $49 per month Lite plan raises the rate limit to only 5 calls per second and keeps the same 100,000 calls per day as the free tier
  • Rate limits top out at 30 calls per second even on the $899 per month Pro Plus plan
  • The Address Metadata endpoint requires Pro Plus at $899 per month and is limited to one app license
  • Metadata CSV export and dedicated support are only in Metadata Enterprise, which is quoted by contact with no published price
  • The 10% and 15% discounts apply only to quarterly and yearly prepayment
