xcall-multi's Introduction

Language	Code Coverage
Java
Rust
Solidity

xcall-multi

xcall-multi is a cross chain messaging service built to mimic regular transaction flows across any interoperable solution.

For full xcall-multi specification see xcall-multi Spec.

Contract Addresses

See Live Contracts for current testnet and mainnet deployments of the xcall-multi contracts on all chains where xCall is deployed.

Building with xcall-multi

For building dapps with xcall-multi see official developer docs.

Available Connection implementations

IBC
- Rust
- Java
BTP is supported natively and does not need a connection contract.
Centralized Connection
- Java
- Solidity
- Rust
Wormhole
- Solidity
LayerZero Adapter
- Solidity

Building a xcall-multi connection

If xcall-multi is deployed, anyone can create a new connection contract to relay messages between xcall-multi contracts. To do this a connection contract has to be developed and deployed on both sides. The base design for a connection can be found in the xcall-multi docs

xcall-multi's Issues

Add fee check on send message to route extra fees to feehandler

When not doing fee checks on xcall there is a chance of contracts own balance being spent which we dont want . To fix it we want to check fees sent and send all extra amounts to xcall fee handler.

BSC - xCall Multi - Deployment

Steps to follow:

Deploying the xCall- multi to BSC
Connect with Parameta team to register the service on BTP
Test on BSC <--> ICON or BSC <--> HAVAH

Testcase - handleRequest

Remove sn on handleMessage.

sn is only used when reporting errors. it should be able to be removed on handleMessage

Avalanche - LayerZero Module

Do not relay error messages on responses.

Error messages plays no role in the message flow and will only be used by front ends. Since you can query the error directly from the event log on executing chain there is no need to relay the messages.

Solidity - Documentation

Allow rollback retries

If a rollback fails it is remove from state which can result in lost data for a application.
Rollback should be able to be retired until successful.

Enable re execution of failed one way messages

Currently when a one way message fails it is simply thrown away, to allow more efficient use of many cross chain protocols we need to guarantee the execution of these messages, so no data is lost.

CallExecuted event log does not hint if the call will give a response

From feedback it has been noted that it could be useful to see if the call you executed yielded a response
