Description

TrustMeBro"Credit without identity. Trust verified on-chain. 1. Project Overview & VisionTrustMeBro is a wallet-native credit scoring platform built on the XRP Ledger (XRPL), designed for the 1.4 billion "credit-invisible" adults globally. This massive demographic includes high-earning expats, freelancers, and cross-border workers who possess real financial lives but zero credit score in the eyes of traditional bureaus. Our mission is to decouple creditworthiness from physical identity. By transforming real-world financial behavior (via Plaid/Stripe) into a portable, verifiable, and private on-chain reputation, TrustMeBro enables individuals to leverage their global income to access financial services anywhere. We bridge the gap between institutional banking data and Web3 privacy, bringing true financial inclusion to the digital nomad generation. 2. The Problem: A Bordered Financial SystemTraditional credit scoring models (FICO, Experian) are fundamentally broken for the modern, mobile workforce:The Expat Paradox: Financial history is geographically locked. A software engineer moving from India to France starts at "credit zero" because their history does not cross borders.The Freelance Penalty: Banks penalize irregular income patterns. A freelance designer earning $8,000/month is often seen as "risky" compared to a lower-earning salaried employee due to "unstable" cash flow. The Privacy Risk: Proving solvency today requires sharing months of raw bank statements with landlords or lenders, exposing every private transaction of your life.DeFi Stagnation: Without a reliable on-chain reputation layer, DeFi lending remains trapped in 95%+ overcollateralization, preventing it from scaling to real-world mass adoption. 3. The Solution: Deterministic TrustTrustMeBro replaces "black-box" identity-based trust with deterministic behavior-based trust anchored on the XRPL.How it Works (Technical Workflow):Identity (XLS-70d): Users connect an XRPL wallet (Xumm/Crossmark). Their wallet address becomes their Decentralized Identifier (DID)—no passport, name, or physical address required.Data Ingestion: Users link their bank accounts via Plaid and professional income via Stripe. This data is processed in an ephemeral, secure environment. The Scoring Engine: A proprietary algorithm calculates a score (300-850) based on:Cash Flow Stability: Ratio of inflows to outflows. Debt Behavior: Historical repayment reliability. Savings Discipline: Balance trajectory and liquidity buffers. On-Chain Activity: Wallet age and transaction health. Soulbound Credentialing (XLS-65/66): Once computed, the score is issued as a non-transferable Soulbound Token. This badge is anchored to the wallet DID on the XRPL.Private Verification: A shareable link allows any third party—landlords, lenders, or DAOs—to verify the score instantly on-chain without ever seeing the user's sensitive banking history. 4. Competitive Advantages & InnovationIncome Pattern Normalizer: Our core technical differentiator. Our engine recognizes and rewards the consistency of freelance payment cycles rather than penalizing their irregularity. Privacy-First (Zero-PII): We do not store transaction data or personally identifiable information (PII). Plaid/Stripe sessions are discarded immediately after computation; only the cryptographic hash of the score persists on-chain.Institutional Bridge: We bring high-fidelity TradFi data (Plaid) into the XRPL ecosystem through a privacy-preserving layer, enabling a credible path from prototype to production. 5. Track Alignment: "Make Waves"TrustMeBro is built to drive measurable ecosystem growth on the XRP Ledger:Sustainable TVL: By providing a trusted credit signal, we enable the under-collateralized lending primitives needed to unlock massive DeFi liquidity.Real-World Assets (RWA): We facilitate real flows of value by allowing credit-invisible users to prove financial reliability for housing, loans and business services globally. Efficiency: Leveraging XRPL’s 4-second settlement and low fees, we provide a reputation system that is updated and verified for a fraction of a cent. 🏁 Final Summary for Judges:"TrustMeBro turns 'Trust me' into 'Verify me. " We are building the portable financial identity for the borderless economy, leveraging the speed and security of the XRP Ledger."

Technical Details

TrustMeBro is privacy-preserving credit infrastructure for AI agents, built on XRPL. Any autonomous agent wallet submits a scoring request gated behind an x402 HTTP micropayment (XRP drops, no API keys). The scoring API - an Express service using the x402-xrpl adapter from t54.ai; verifies payment via the XRPL testnet facilitator, pipes the agent's on-chain data through a RISC0 zkVM guest circuit. The circuit ingests six signals:transaction volume, counterparty diversity, treasury balance trend,wallet age, task completion rate, and API success rate. It outputs a deterministic grade (A–F), risk tier, and confidence level - no ML, fully auditable, same inputs always produce the same grade. A Groth16 receipt is generated; its hash is anchored on XRPL via a Payment+Memo transaction. A soulbound XLS-70 Credential (CredentialCreate + CredentialAccept) is minted to the agent's wallet as a permanent, portable proof of creditworth.
