A full-stack revenue share dApp for GNG token holders

GNG needed a full-stack decentralized application that could give token holders a clear way to deposit their tokens into a depository and participate in revenue share distribution rounds.

The system was designed around a simple idea. Holders could lock tokens into the depository, and when a revenue share round was created, eligible claim amounts were calculated based on the dividend fee per token and the amount each holder had deposited.

This created a more structured incentive layer for the community while supporting the project’s goal of reducing sell pressure by rewarding holders who kept their tokens deposited in the system.

The project needed more than a basic staking-style interface. The payout model was tied to actual profit distribution logic, not fixed interest, fixed yield, or APY mechanics. That meant the system had to support variable distribution rounds where each holder’s share could be calculated off-chain and claimed on-chain with proof.

The smart contract also needed to manage token deposits and withdrawals securely, track total deposits, prevent reentrancy, and make sure users could only claim the exact payout they were eligible for during an active round.

On the application side, users needed a clean dashboard to connect their wallet, view deposited balances, deposit or withdraw tokens, and claim their available share without needing to understand the underlying Merkle proof system.

The solution included a Solidity smart contract for the core token depository and payout logic, a React frontend for the user dashboard, Firebase for supporting data workflows, and JavaScript backend functionality for round preparation and claim data handling.

Users could deposit GNG tokens into the contract, withdraw available deposited tokens, and claim their calculated share when a distribution round was live. The contract used Merkle proof verification so each user could claim only the amount assigned to their wallet for that round.

Admin controls were added for setting claim roots, opening new distribution rounds, pausing claims, finalizing rounds, and recovering unclaimed funds after a round ended. The contract also emitted events for deposits, withdrawals, claim rounds, root updates, status changes, and successful holder claims.

The frontend turned the contract into a usable product experience, giving holders a direct interface for participating in the depository and claiming their share without manually interacting with the contract.
