Welcome to City Protocol?
One-Stop Neofinance & Attention Stack for Founders and Developers
City Protocol is building the foundational infrastructure that enables founders to spin the Attention-Capital Flywheel for their audiences. We provide a comprehensive suite of tools that enable projects to seamlessly connect user acquisition, retention, and monetization.
Our vision is to become the consumer finance infrastructure layer that provides all the required Neofinance and Viral Growth Components for the founders-and-developers landscape today.
By offering a non-custodial, modular, and open-access infrastructure, City Protocol serves as the distribution layer that connects vault operators, project founders, and everyday users through shared on-chain infrastructure, especially in an AI-accelerated world where everyone can be a founder.
Why City Protocol
Non-Custodial Retain full control over assets through smart contracts with audited risk boundaries
Institutional-Grade Standardized smart contract framework with transparent reporting
Fully Modular Covers modules across Vault, Yield, Swap, Payment, Lending, and KYC/AML
Easy Integration Works with apps, Web3 projects, and trading platforms via unified SDK/API
How City Protocol Works
City Protocol is designed to simplify and optimize growth and capital flow for founders and applications through a dual-layered approach. Below is a high-level walkthrough of how City Protocol operates:
Attention Layer: Engineer Virality
The user-facing interface for measuring mindshare and distributing rewards:
AIUGC Layer
AI-powered user-generated content that lowers the barrier to user-driven growth
Mindshare Arena
Information market tracking project mindshare via heatmaps and leaderboards
Reward Hub
UGC incentive platform where users follow, post, and engage to earn token bonuses
Capital Layer: Deploy Neofinance Infrastructure
ERC-4626 compatible vaults with asynchronous subscriptions, NAV-based settlement, role-based permissions, and configurable fee logic.
Six Core Modules:
Yield Automated return generation via Gauntlet, Steakhouse, Superstate, and more
Swap Best-execution routing via PancakeSwap, Aerodrome, Uniswap, Li.Fi
Payment Fiat and crypto rails via Gnosis Pay, Zerohash, StraitsX, and AI-native OpenClaw integration
On/Off Ramp Global fiat gateways via Moonpay, Ramp, Mercuryo, Metacomp
Lending/Borrowing Deep liquidity via AAVE, Compound, Morpho, Maple
KYC/AML Compliance via Persona, Veriff, Onfido, Comply Advantage
Developer Access & Integration
Unified SDK
The @cityprotocol/core package provides a TypeScript SDK that wraps complex multi-step transactions into simple asynchronous functions.
Portfolio Client
Access indexed vault data, user transactions, and historical TVL snapshots through the CityPortfolioClient subgraph interface.
Chain Abstraction Users deposit from any supported EVM network and receive vault shares, while strategy execution occurs on the optimal chain.
Core Features
Modular Architecture Developers pick and choose specific modules, from a simple swap interface to a complex yield-bearing vault with KYC gating.
Attention-Capital Flywheel The only neofinance platform that connects mindshare measurement directly to on-chain capital deployment.
Institutional-Grade Security Independent third-party NAV valuation, MPC/multisig approvals, separation of duties, and immutable on-chain reporting.
Chain Abstraction Unified user experience across L1 and L2 environments without fragmenting liquidity.
AI-Native Payments Integration with OpenClaw enables x402 standard payments, AI sub-accounts, and agent-driven commerce for the $5T projected AI-mediated transaction market.
Transparent Fee Structure All fees encoded directly in smart contracts and visible prior to deposit — eliminating information asymmetry.
Integration Benefits
Revenue Impact
Passive Income Consistent yield generated through management fees, performance fees, and entry/exit fees, distributed automatically as shares at each settlement.
User Growth Higher retention through Viral City's engineered virality and the Reward Module's UGC incentives that convert passive holders into active contributors.
Competitive Edge Market leadership through a complete neofinance stack that would otherwise require individual connections to yield, swap, payment, vault, fiat ramps, lending, and KYC/AML.
Technical Advantages
Performance Asynchronous request-then-settle workflow ensures consistent pricing and reduces operational complexity at scale.
Scalability Built in Solidity, deployed on Base and all EVM-compatible chains with native cross-chain messaging.
Security Separation of duties between Vault Admin, Curator, Valuation Provider, and Whitelist Manager roles, reinforced by independent audits.
Zero Custody Risk City Protocol never takes custody of user funds. Assets are held exclusively in audited smart contracts with explicit risk parameters.
