Please note this motion replaces [motion 256](https://polkadot.polkassembly.io/motion/256) due to an error on the proposal weight - fixed on this one. BUT THE ORIGIN IS STILL INCORRECT. THIS WILL BE REPLACED BY A NEW MOTION.

Five more parachains have requested an HRMP channel with Statemint. This motion accepts them all and opens return channels.

- **Parachains that aim to open channels**: 2021, 2031, 2032, 2035, 2046.

**Call Construction**

These are constructed backwards. That is, the call to use as the proposal is at the end.

**Relay Chain Call to Execute**

First, we need the call that Statemint will execute on the Relay Chain. This accepts all channel requests and returns channel requests to the initiators.

```

**Message from Statemint**

The above message needs to come from Statemint. So we put it into an XCM (the “Transact” instruction) along with purchasing some execution capacity and returning any leftover fees to the Treasury.

```

**Proposal on the Relay Chain**

But, governance is on the Relay Chain, not Statemint. So take some DOT from the Treasury (100 DOT for 10 channels at 10 DOT each plus 2 DOT for fees) and send a message to Statemint telling it to send a message back. This is the proposal to vote on.
