Epic 12 — Plugin & Extension System
Goal: Let power users extend CalcPad.
Story 12.5: Built-in Plugin: Crypto & DeFi
As a crypto-focused user, I want to query cryptocurrency prices and DeFi protocol data in CalcPad expressions, So that I can incorporate live blockchain data into my calculations.
Acceptance Criteria:
Given a user types ETH gas price in a sheet
When the expression is evaluated
Then the current Ethereum gas price is fetched (from an API such as Etherscan or similar)
And the result is displayed in gwei (e.g., 25 gwei)
Given a user types AAVE lending rate in a sheet
When the expression is evaluated
Then the current AAVE lending rate is fetched from DeFi Llama or the AAVE API
And the result is displayed as a percentage (e.g., 3.45%)
Given crypto price data is sourced from CoinGecko
When a user types BTC price or ETH price
Then the current market price is returned in USD (or user's preferred currency)
And the data source is CoinGecko's public API
Given DeFi protocol data is sourced from DeFi Llama When a user queries lending rates, TVL, or yield data Then the data is fetched from DeFi Llama's API And the result is formatted appropriately (percentage for rates, currency for TVL)
Given the API is unreachable or rate-limited When a user queries crypto or DeFi data Then a cached value is used if available (with a staleness indicator) And if no cached value exists, an error message indicates the data source is unavailable
Given a user types an unsupported token or protocol name When the expression is evaluated Then an error message indicates the token or protocol was not recognized And suggestions for similar valid names are shown if possible
