Lazy Workshop

Date: 2025-01-20

Context

Since Celestine Sloth Society have his NFT Collection on other blockchains, there is a limit on what this NFT can do in terms of functionality.

Celestine Sloth Society wants to have his own blockchain Lazychain to evolve his main product NFT collection.

Lazychain is a community-driven blockchain for Sloths and on chain fun powered by Astria with Celestia underneath.

App Specific Sequencing (ASS) powered by Astria's sequencing layer maximizes the value that flows back to the Sloth community.

Our primary goal is to demonstrate that blockchain technology can be accessible and useful for everyday applications.

We're building a platform for developers to create applications users actually want to use, combined with distribution to an existing crypto native user base.

Whether you're building a social platform, a gaming application, or another consumer service, Lazychain provides the infrastructure and community support you need LazyDev.

Architecture

We are going to use a modular blockchain using Sovereign Rollups using Geth as Execution Layer, Astria as Settlement and consensus layer and Celestia as Data Availability Sampling layer.

You can find details about our architecture on docs.

Hands on LazyDev, in control

As your first assignment, we encourage you to do a NFT staking contract for the campaign Sleep2Earn.

But first, let me tell you how is a normal day in Lazy development department.

A Product manager work with the Lazy community via questions or polls and voting governance to select most relevant needs.

Then with the CEO establish a course of decisions and funding.

With the help of Analist, Technical leader and a UX give life to a project on docs.

This project is taken by the Project Manager and the Technical Leader and create all the Tasks need it and a Plan to try to fulfill.

The day has come to Stake2Earn campaign with NFT staking contract.

Your Technical leader create and initialize a project with all the tech need it.

It assigns you some issues according to a Plan.

Are you ready for what it takes the challenge?

Tips

Build contracts

forge build

Debug contracts

forge test --match-contract StakingTest --match-test test_ImReady -vvvv

Generate coverage report

clear && forge coverage --report lcov && genhtml -o report --branch-coverage lcov.info --ignore-errors inconsistent --ignore-errors category

forge coverage --no-match-path 'test/invariant/**/*.sol' --report lcov
lcov --extract lcov.info --rc branch_coverage=1 --rc derive_function_end_line=0 -o lcov.info 'src/*' 
genhtml lcov.info --rc branch_coverage=1 --rc derive_function_end_line=0 -o coverage

Run local deploy

source .env
anvil

source .env
forge script script/Deploy.s.sol:Deploy --fork-url $CHAIN_RPC --broadcast
