Setup testnet

Registrar testnet

To install pop-cli for the testnet or use our deployed testnet, follow these steps:

1. Clone and Run the Pop-CLI

git clone https://github.com/rotkonetworks/pop-cli
cd pop-cli
cargo run up parachain --file ~/rotko/pop-cli/tests/networks/rococo+people.toml --verbose

2. Set WebSocket Endpoint

Use either the provided endpoint or your local testnet for people-rococo:

wss://dev.rotko.net/people-rococo

3. Generate Call Data

In the Polkadot UI, navigate to Extrinsics and create a transaction to add a registrar. Copy the calldata from the generated transaction.

Example transaction for call data extraction: Extrinsics decode tool

4. Relaychain Sudo Rights Requirement

Executing the above call from a local parachain account will fail due to lack of rights. You need sudo access at the relaychain level.

5. Create a Sudo Call on the Relaychain

Go to the relaychain’s Sudo page and submit a sudo call with the following XCM transaction:

#![allow(unused)]
fn main() {
xcmPallet::send(
    dest: XcmVersionedLocation::V4(StagingXcmV4Location {
        parents: 0,
        interior: StagingXcmV4Junctions::X1([Lookup71::Parachain(Compact(1004))])
    }),
    message: XcmVersionedXcm::V4(StagingXcmV4Xcm {
        0: StagingXcmV4Instruction::UnpaidExecution {
            weightLimit: XcmV3WeightLimit::Unlimited,
            checkOrigin: None
        },
        1: StagingXcmV4Instruction::Transact {
            originKind: XcmV3OriginKind::Superuser,
            requireWeightAtMost: SpWeightsWeightV2Weight {
                refTime: Compact(5000000000),
                proofSize: Compact(50000)
            },
            call: XcmDoubleEncoded::new(Bytes::from_hex("0x3200001cbd2d43530a44705ad088af313e18f80b53ef16b36177cd4b77b846f2a5f07c"))
        }
    })
);
}

Submit this sudo call as Alice (the first validator in the network):

6. Verify Registrar Creation

Watch the Explorer for events confirming the registrar was created on the parachain (people-rococo).
