## TL:DR
The following proposal registers USDT from Statemine as xcUSDT on Moonriver.

## Summary
We propose to register USDT from Statemine as xcUSDT on Moonriver. The XC-20 has the following details:

 - Multilocation: *{ "parents": 1, "interior": {"X3": [ { "Parachain": 1000}, {“PalletInstance”: 50},{ "GeneralIndex": 1984 }]}}*
 - Decimals: *6*
 - Name: *Tether USD*
 - Symbol: *xcUSDT* 

The official Asset ID from Statemine was extracted from [Tether’s official website](https://tether.to/en/supported-protocols/).

The proposed fee to execute the XCM was calculated using the current KSM to USD price ratio.

## Proposal
Proposal #85 with the following hash: *0x0ea6d0cf368bc6f02a0397837a00b32f2bf25745a64ed9265cef0c4f8a0ff535*

## Technical details:
The procedure to register an asset on Moonriver is as follows:

 - *assetManager.registerAsset* to register the asset with the information provided in the summary
- *system.setStorage* to store a revert code in the asset's storage. This is so that smart contracts can interact with the XC-20 (through the EVM)

Once the proposal is enacted, *xcUSDT* will live under asset ID *133057993812922544048267207069832508503*. Consequently, the XC-20 address would be *0xFFFFffFf641a099723723c870F7368C47f96F457*

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

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.
