Hackathon Guide

One-page hackathon guide for building chains and contracts with Pop CLI.

Introduction

Pop CLI is an all-in-one tool for Polkadot development. It streamlines both parachain and smart contract workflows so you can go from idea → demo during a hackathon.

Pop CLI simplifies development with:

  • Quick initialization of development environment.

  • Project scaffolding from predefined templates.

  • Easy launch and management of local development networks.

See also: Quickstart Parachain Development with Pop CLI (official Polkadot docs)

Prerequisites

Install Pop CLI:

cargo install --force --locked pop-cli

Confirm the installation:

pop --help

Set up your development environment: To build Polkadot SDK–based chains, make sure your local toolchain is ready. The Install Polkadot SDK Dependencies guide covers this step by step.

Or automate it with:

pop install

Chain Development (Parachains)

Build and run a local parachain quickly; deploy when ready.

TL;DR Flow

# 1) Scaffold (choose provider/template interactively)
pop new chain

# 2) Build your chain
cd my-chain && pop build --release

# 3) Run a local network (Zombienet config)
pop up network -f ./network.toml

Congrats! You’ve spun up a network with your parachain running!

Other useful commands

# 4) Interact with your chain (You can secure signing via browser wallet).
pop call chain # `pop call chain  --use-wallet`

# 5) Register the rollup on Paseo or deploy using Polkadot Deployment Portal
pop up
# And follow the interactive guide:

Contract Development (ink!)

Pop CLI introduces experimental support for ink! v6 smart contracts running on PolkaVM (RISC-V) via pallet-revive.

⚠️ This path is alpha. If you want to try it during the hackathon, install Pop CLI from the v6 branch:

cargo install --git https://github.com/r0gue-io/pop-cli.git --branch v6.0.0-alpha.4 --locked

TL;DR Flow

# 1) Scaffold (choose provider/template interactively)
pop new contract

# 2) Build your contract
cd my-contract && pop build --release

# 3) Deploy (Pop CLI will run a local network by default; add `--url` to target a remote RPC)
pop up # `pop up --url wss://passet-hub-paseo.dotters.network`

# 4) Interact with your contract (You can secure signing via browser wallet).
pop call contract # `pop call contract  --use-wallet`
