Project description:
"Hello,

We are looking for a professional Web3 / blockchain developer (or a small team) with experience building Farcaster Mini Apps and developing production-level smart contracts.

⸻

Project Idea

We want to build a Mini App on Farcaster that works as a gig / bounty marketplace.
The idea is similar in spirit to [login to view URL], but with our own logic, access rules, and on-chain mechanisms.

Core features:
• Users can create gigs, browse gigs, accept gigs, and complete gigs.
• The Mini App must implement token/NFT-based access control from the beginning.
• Only eligible users (token or NFT holders) can create or accept gigs.
• The system must include smart contract logic at launch, not just in future phases.

⸻

Smart Contract Requirements (Mandatory from Day One)

The developer will need to design, develop, and deploy the smart contracts that handle:
• On-chain gig lifecycle (creation → acceptance → completion)
• Permission checks (token gating / NFT gating)
• Optional escrow-style token locking for gig rewards
• Emitting events for Mini App to sync UI state
• Future extensibility (reputation, payments, token rewards, etc.)

Contracts should be secure, gas-efficient, upgrade-friendly, and written in Solidity.

⸻

Developer Responsibilities
• Build the Farcaster Mini App with:
• Gig creation
• Gig listing
• Gig acceptance
• Gig completion
• Integrate wallet connections + on-chain validations.
• Build and deploy the required smart contracts.
• Provide APIs / endpoints (if needed) for indexing and UI state.
• Create a simple, clean and user-friendly UI optimized for Mini App usage.
• Deliver an architecture that is scalable, modular, and easy to extend.

⸻

Requirements
• Strong experience in Web development (HTML, CSS, JavaScript)
• Experience building Farcaster Mini Apps or Frames
• Proven experience with smart contract development (Solidity)
• Understanding of:
• Token gating
• NFT ownership validation
• Wallet integration
• On-chain state management
• Familiarity with Ethereum tooling (Hardhat, Foundry, [login to view URL], Wagmi, Safe, etc.)
• Reliable and able to collaborate effectively with a team

⸻

Project Goal

To create a functional, Web3-native Mini App inside Farcaster where users can post and complete gigs every day.
The platform must be trustless, transparent and fully powered by on-chain logic and token-based access control from day one — with room to grow into token payments, reputation systems, and advanced contract interactions.

Reference Project: [login to view URL]

A closely related example is [login to view URL], a Farcaster Mini App created by corbin.eth.

[login to view URL] demonstrates:
• A gig/bounty system inside Farcaster
• Token-based rewards
• Users completing tasks and receiving tokens in their wallets
• Fully native Mini App experience inside Warpcast and other Farcaster clients

Our project takes inspiration from this model, but will have a different architecture, access-control logic (NFT gating), and customizable gig workflow.

This reference helps developers understand the direction and complexity of what we’re building." (client-provided description)
