Vault Street Tycoon

## Introduction Vault Street Tycoon is an idle DeFi bank simulation and tycoon game built on the Robinhood Chain. Set across a living, low-poly 3D city street complete with animated cars and coin-fountain buildings, players start with a single bank branch and expand into a sprawling financial empire. The game combines classic idle-tycoon progression with genuine Web3 tokenomics, competitive leaderboards, and a free-to-mint NFT collection — all anchored by the motto: **BUILD · EARN · DEFEND**. ## Gameplay Vault Street Tycoon's core loop revolves around three interlocking activities: - **Build:** Open up to 8 bank branches across the plaza, each upgradeable through 8 distinct tiers. Fill each branch with up to 20 different financial assets — from gold coin stacks and bonds to high-yield instruments — to maximize your lending capacity and daily yield output. - **Earn:** Your branches compete against rival player banks in real time. The bank that generates the highest yield earns the largest share of the daily in-game rewards pool, which scales to $22.1 billion in-game currency at the Tier 8 level. - **Defend:** Secure your vault against rival disruptions. Vault management and defensive upgrades prevent competitors from eroding your yield lead and protect your position on the plaza leaderboard. Players are identified by a custom handle displayed on the plaza leaderboard. Founder branch members who join during Early Access have their handle displayed before anyone else, giving lasting social prestige within the game world. ## Key Features - **8 Bank Branches & 8 Tiers:** A deep progression system with 64 total upgrade states across the branch network, keeping gameplay engaging well past launch. - **20 Financial Assets:** A diverse asset catalogue (from basic coin vaults to complex instruments) lets players specialize their bank strategy and differentiate from rivals. - **Daily Rewards Pool:** Competitive yield mechanics distribute from a tiered daily pool, peaking at $22.1 billion in-game currency for Tier 8 banks, incentivizing active management. - **Referral Free Mint:** Top referrers in the Early Access campaign earn a guaranteed free NFT mint spot — the leaderboard is public and updates live. - **NFT Whitelist — 1,000 Supply, Free Mint:** The Vault Street founding NFT collection has a supply of 1,000 on Robinhood Chain with a free mint. Players and partner communities can apply for whitelist spots through the collab portal. - **Interactive 3D Diorama:** The homepage features a draggable WebGL city diorama with animated cars, coin fountains, and clickable buildings — tapping any building triggers a gold coin burst. ## Blockchain Integration Vault Street Tycoon is deployed on the **Robinhood Chain** EVM layer: - **EVM Wallet Integration:** Players connect EVM-compatible wallets (0x… addresses) to submit Early Access and NFT whitelist applications. No gas fees are charged during sign-in or application submission. - **X (Twitter) OAuth:** Identity is linked via X sign-in. One X account maps to one wallet, preventing Sybil manipulation of the referral and whitelist systems. - **In-Game Token:** The rewards pool distributes an in-game token earned by out-yielding rival banks. Token contract details are to be announced. - **Free Mint NFT Collection:** 1,000 Genesis NFTs on Robinhood Chain, available at free mint for whitelisted wallets. Final whitelist spots are confirmed on X before the mint date. ## Getting Started Vault Street Tycoon is currently in its **Early Access / Development** phase.
