ic-alloy is an open source project to make the Alloy.rs support libraries available to ICP developers. Using Alloy instead of interacting with the EVM RPC canister directly provides a drastically simpler developer experience.

Overview
this demonstrates how to connect Chainlink Price Feed to Canister with external EVM-compatible chains and Ideal for decentralized finance (DeFi), lending borrowing, oracles on the Internet Computer
- Query on-chain price feed data (e.g., Chainlink) directly from Solidity contracts
- Read real-time price data from decentralized applications on ICP without relying on off-chain oracles.
Cross-Chain Data Access:
Read price data from Chainlink’s on-chain sources via EVM and Fully decentralized and serverless
Features:
Asset Management
-
Add/remove assets with custom symbols
-
Update asset information
-
Owner-specific asset configurations
Price Feed Integration
-
Automatic validation of Chainlink price feeds
-
Configurable stale data thresholds (heartbeat) per asset to define how long price data is considered valid
-
Allows you to set a custom
staleThresholdin seconds during asset registration or update. -
Protects against using outdated or frozen price feeds
-
Fallback mechanisms for failed price lookups
Conversion Tools
-
Accurate token ↔ USD conversions
-
Handles different decimal precisions
-
Bulk conversion operations
