IC EVM Connect (an ICRC-3 to EVM proxy )

Showcase

Hi everyone,

excited to announce the finalisation of our project IC-EVM Connect.

Project Highlights

The ICP-EVM Proxy is a proof-of-concept (PoC) project designed to enhance interoperability between the Internet Computer Protocol (ICP) and EVM-compatible platforms, such us decentralized exchanges (DEXes): ICPSwap, ICPEx, and others, through integration with Dexscreener and similar platforms.

The project focus on developing an adapter to facilitate the translation of ICRC-3 (ICRC-1/standards/ICRC-3 at main · dfinity/ICRC-1 · GitHub) logs into EVM-compatible RPC. It aims to standardize the ICRC-3 protocol for DEXs developed on IC, simplifying integration with third-party tools and enhancing interoperability within the IC ecosystem.

Our work allows exposing this information as an EVM to any other tooling, enabling and facilitating further integration work.

Key Components

  1. Counter Canister: A simple Rust-based canister that serves as an example of basic ICP functionality. It generates events when incrementing or retrieving the counter value.
  2. DEX Canister: A Rust-based canister that implements basic decentralized exchange functionality. It manages currency pairs, token operations (mint/burn), and generates ICRC-3 compatible events for all operations.
  3. Logger Canister: A Rust-based canister that implements ICRC-3 compatible logging. It captures and stores events generated by other canisters (like the Counter and DEX Canisters) in a standardized format.
  4. EVM Adapter Proxy: A Go-based service that acts as a bridge between ICP and EVM-compatible systems. It performs two main functions:
  • Retrieves ICRC-3 log data from the Logger Canister and translates it into EVM-compatible event logs.
  • Exposes EVM RPC compatible methods, allowing interaction with ICP canisters using familiar Ethereum tooling.
  1. SubQuery Indexer: A Node.js-based service that indexes the translated EVM-compatible data. It provides a GraphQL API for efficient querying of the indexed data.

Workflow

  1. Users can interact with both Counter and DEX Canisters:
  • Counter operations: increment and get value
  • DEX operations: manage currency pairs, mint/burn tokens, check balances
  1. All operations generate events that are captured and stored by the Logger Canister in ICRC-3 format
  2. The EVM Adapter Proxy retrieves logs from the Logger Canister and translates them into EVM-compatible formats
  3. The SubQuery Indexer processes the translated data, making it queryable through a GraphQL API

Use Cases

This PoC demonstrates potential use cases such as:

  • Enabling Ethereum developers to interact with ICP canisters using familiar tools and methods
  • Allowing ICP dapps to integrate with existing Ethereum-based analytics or monitoring tools
  • Facilitating cross-chain applications that span both ICP and EVM-compatible blockchains
  • Demonstrating DEX functionality with standardized event logging and querying

Limitations

As a proof-of-concept, this project has several limitations and is not intended for production use. Some key points to note:

  • Simplified implementation of ICRC-3 logging and EVM event translation
  • Limited error handling and edge case coverage
  • Not optimized for high-throughput or large-scale deployments
  • In-memory storage for logs in the Logger Canister, which is not suitable for long-term or high-volume data storage
  • Basic DEX functionality without order matching or complex trading features

Future Work

The ultimate goal of this project is to establish a uniform DEX interface akin to that used by Ethereum, promoting a standardized, easily accessible ecosystem for DEX applications across various platforms.

We are currently seeking feedback from the community and are excited about the potential for this integration to become a foundational step toward broader interoperability and usability.
