The Monolith

Overview

The Monolith is a mobile game that combines community-driven block placement with cryptocurrency staking on Solana — think r/Place meets DeFi, in 3D. Players stake USDC to claim and maintain blocks in a shared 3D tower, each featuring an animated character called a “Spark” that evolves based on player engagement.

As the sole creator and founder, I designed, developed, and shipped the entire product — from the 3D rendering pipeline and on-chain smart contracts to the real-time game server and mobile app.

The Problem

Community-driven social experiments like Reddit’s r/Place captivated millions, but they lack persistence and real economic stakes. Meanwhile, DeFi protocols struggle with engagement beyond speculation. The Monolith bridges this gap by creating a persistent, stake-based 3D world where ownership is meaningful, engagement is rewarded, and every block tells a story.

How It Works

Stake & Claim

Players stake USDC on Solana to claim a block on the tower. Each block becomes a canvas for self-expression — customizable with 16 colors, 48 emoji, 11 animated styles, and 7 textures.

Daily Engagement

Blocks have a charge decay system — players tap their block daily (~30 seconds) to keep it alive. Miss 3+ days and your block goes dormant, becoming claimable by others. Consistent engagement is rewarded with streak multipliers up to 3x.

Spark Evolution

Each block hosts a “Spark” — an animated character that evolves through 5 tiers: Spark → Ember → Flame → Blaze → Beacon. Evolution is driven by sustained engagement and streak maintenance.

Social & Competition

On-chain leaderboards track the tallest towers (Skyline), brightest Sparks, longest streaks, and XP ranks. Players interact through “poke” mechanics and compete across a 10-level progression system with 7 achievement types.

My Role & Responsibilities

As the Founder & Solo Developer, I was responsible for:

• 3D Engine & Rendering: Built the entire 3D pipeline with React Three Fiber and custom GLSL shaders (ambient occlusion, subsurface scattering, GGX specular). Rendered 650+ blocks using InstancedMesh in just 3 draw calls, optimized for 60 FPS on mobile
• Smart Contract Development: Wrote the Anchor (Rust) program on Solana for USDC staking, block ownership, and on-chain verification
• Real-time Game Server: Designed and implemented the Colyseus server on Node.js for instant game state synchronization
• Mobile App: Built the cross-platform app with Expo and React Native, including Mobile Wallet Adapter integration
• Backend & Data: Architected the Supabase (PostgreSQL) backend for persistent game state, player profiles, and analytics
• On-chain Integrations: Integrated Tapestry Protocol for social graphs, MagicBlock SOAR for leaderboards, and Solana Blinks for shareability

Technical Architecture

Rendering Pipeline

The biggest technical challenge was rendering 650+ interactive 3D blocks at 60 FPS on mobile devices. The solution uses InstancedMesh to batch all blocks into just 3 draw calls, with custom GLSL shaders handling:

• Ambient Occlusion: Realistic shadow depth between blocks
• Subsurface Scattering: Translucent glow effects for Spark evolution
• GGX Specular: Physically-based reflections for block materials

Hybrid Architecture

The system separates fast game logic from blockchain finality:

On-chain (Anchor/Rust): USDC staking, block ownership, verification
Server (Colyseus/Node): Real-time game state, instant feedback
Client (Expo/R3F): 3D rendering, animations, wallet adapter
Database (Supabase): Player profiles, analytics, persistent state

This allows instant gameplay feedback while maintaining trustless on-chain ownership verification.

Testing & Quality

Over 320 tests across the full stack:

• 222 unit tests for mobile app
• 84 server integration tests
• 14 on-chain smart contract tests

What I Learned

Building The Monolith deepened my expertise in:

• 3D Graphics on Mobile: Shader optimization, instanced rendering, and hitting 60 FPS budgets on constrained hardware
• Solana Program Development: Writing and testing Anchor programs for complex staking and ownership logic
• Real-time Multiplayer: Designing state synchronization between Colyseus, Supabase, and on-chain data
• Game Design: Balancing engagement mechanics (decay, streaks, evolution) with economic incentives (staking, claiming)
• Full-stack Mobile: Shipping a production Expo app with wallet integration, 3D rendering, and real-time networking
