+## Project Overview :page_facing_up:
+
+RFPs [https://github.com/w3f/Grants-Program/blob/master/docs/RFPs/xcm-tool.md](https://github.com/w3f/Grants-Program/blob/master/docs/RFPs/xcm-tool.md)
+
+### Overview
+
+XCM (Cross-Consensus Message) is a messaging format and language used to communicate between consensus systems.
+
+After https://github.com/paritytech/polkadot-sdk/pull/2522 was merged, the polkadot ecosystem evolved from cross-chain interaction
+between parachain to cross-chain interaction between ethereum and polkadot.
+
+Therefore, this proposal is an extension of [xcm-tools](https://github.com/gmajor-encrypt/xcm-tools) to improve the
+practicability of this package further and increase support for xcm v3 and ethereum bridge support.
+
+### Project Details
+
+1. Support XCM v3, support the setTopic instruction.(https://forum.polkadot.network/t/xcm-upgrade-to-v3/4690)
+   After the xcm V3 upgrade, messageId will be used as a credential for message tracking, which is different from using
+   message_hash(blake2_256(message)).
+   The xcm-tools will use a messageId as the credential for message tracking.
+
+2. Add send bridge xcm messages to bridgeHub Support
+
+    * `transfer_assets`
+
+3. Get the result after cross-chain and the block_hash (block_num) of the execution after sending xcm
+
+### Ecosystem Fit
+
+- Where and how does your project fit into the ecosystem?
+  XCM developers or users who want to use the XCM Feature. A solution is provided here. You can send and track your XCM
+  transaction
+
+- Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase,
+  yourself)?
+  wallet & explorer & parachain developer
+
+- What need(s) does your project meet?
+  Provide a solution for parachain and parachain interaction,between polkadot and ethereum, transactions between parachain and relaychain,
+  xcm message parse, and the xcm txn tracking. It can be easily integrated into the application of Golang or directly used as Tools.
+
+- Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?
+  No

+The xcm protocol is constantly being updated, and I will continue to maintain this tool to make it more convenient for
+users to use.
