The Multichain team in collaboration with the Equilibrium dev team has developed a solution for cross-chain transfers by using xTokens system contract. This development allows for user-friendly asset transfers between EVM networks like Ethereum, Polygon, e.t.c., and Polkadot ecosystem parachains.

Multichain is a cross-chain router protocol designed for bridging assets between different blockchains. Multichain supports more than 70 blockchain networks both EVM and non-EVM with ~$1.6B TVL. 

We propose a creation of 3 distinct XC-20 tokens to leverage the cross-chain smart contract functionality on Moonbeam. Here are the details of proposed tokens including corresponding Ethereum and Moonbeam ERC-20s:

| Symbol | Name | Decimals | Ethereum ERC-20 | Moonbeam ERC-20 |
| - | - | - | - | - |
| xcWBTC.multi | Wrapped BTC | 8 | [WBTC](https://etherscan.io/token/0x2260fac5e5542a773aa44fbcfedf7c193bc2c599) | [WBTC](https://moonscan.io/address/0x818ec0a7fe18ff94269904fced6ae3dae6d6dc0b) |
| xcETH.multi | Ethereum | 18 | ETH | [ETH](https://moonscan.io/address/0xfa9343c3897324496a05fc75abed6bac29f8a40f) | 
| xcUSDC.multi | USD Coin | 6 | [USDC](https://etherscan.io/token/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48) | [USDC](https://moonscan.io/address/0x818ec0a7fe18ff94269904fced6ae3dae6d6dc0b) |

When registered, these assets will be available to all of the Polkadot parachains connected to Moonbeam, opening up a way for a first truly cross-chain asset bridging solution for the entire Polkadot ecosystem.

Send a batch of dispatch calls.

May be called from any origin.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then call are dispatch without checking origin filter. (This includes
bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>

This will return `Ok` in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
`BatchInterrupted` event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the `BatchCompleted`
event is deposited.

- Multichain and Equilibrium have developed a solution for transferring assets between different blockchains.
- They propose creating three XC-20 tokens: xcWBTC.multi, xcETH.multi, and xcUSDC.multi.
- These tokens will allow for easy transfers between Ethereum, Moonbeam, and other Polkadot parachains.
- The tokens will be available to all Polkadot parachains connected to Moonbeam.
- This will be the first cross-chain asset bridging solution for the Polkadot ecosystem.
