Mamdo

Overview

Mamdo is a high-performance social trading platform deployed on Mantle Network, combining the virality of social media with the financial mechanics of DeFi. The platform enables users to tokenize their posts through automated bonding curve deployment, trade creator tokens with sub-second settlement, and access leveraged perpetual positions on any user-generated asset - all within a unified mobile-first experience.

Problem Statement

Current social and trading platforms suffer from fundamental fragmentation and trust issues:

Content creators lack direct monetization pathways beyond sponsorships and platform-dependent revenue sharing
Trading platforms exist in isolation from social discovery, requiring context-switching between apps
Centralized exchanges control custody of user funds with opaque backend systems
Mobile DeFi experiences are fragmented across multiple disconnected applications
Wallet security relies on single-point-of-failure private key storage
Creator-fan economic relationships are mediated by extractive intermediaries

Solution

Mamdo implements a unified social-trading infrastructure with the following properties:

Post-to-Token Pipeline - Every trade post automatically deploys a bonding curve token, creating instant liquidity for creator shares
Non-custodial Architecture - User funds remain in personal wallets secured via Shamir's Secret Sharing threshold cryptography
Unified DeFi Access - Swap, perpetuals, lending, and staking accessible from single interface with in-app DApp browser
On-chain Settlement - All trades execute atomically through verified smart contracts with deterministic pricing
Permissionless Access - Wallet-based or email authentication; no mandatory KYC for basic functionality

Security Architecture

Shamir's Secret Sharing - Private keys split across multiple encrypted shards; threshold reconstruction prevents single-point compromise
AES-256 Encryption - All sensitive data encrypted at rest using hardware-backed secure storage
PIN-gated Wallet Access - 4-digit PIN required for transaction signing and balance viewing
Zero-knowledge Proof Integration - Planned implementation for private portfolio verification
Expo Secure Store - Hardware-backed keychain storage on iOS/Android devices

Bonding Curve Mechanics

Linear pricing formula: price = basePrice + (slope × currentSupply)
1 billion total supply per token with 5% creator allocation
Lazy minting for gas-efficient creator token distribution
Slippage protection via min/max output parameters
Protocol fee collection on buy/sell operations
