Deliverable 1: Native XLM Wallet Support via MPC Signing
Implement Stellar ed25519 key generation and transaction signing through MPCVault's MPC (Multi-Party Computation) infrastructure. Users can create Stellar accounts, view XLM balances, and send/receive XLM natively within the MPCVault platform.
How to measure completion: Live demo showing XLM account creation, balance display, and a successful send/receive transaction flow using MPC-distributed signing (no single party holds the full private key).
Deliverable 2: Stellar Issued Asset & Trustline Management
Support adding, removing, and managing trustlines for Stellar-issued assets (e.g., USDC, yXLM, AQUA). Display issued asset balances alongside XLM. Enable sending and receiving of issued assets through trustline-enabled accounts with memo support (text, ID, hash, return) for exchange compatibility.
How to measure completion: Demo showing trustline creation for at least 2 issued assets, balance display for each, and a successful issued asset transfer with memo field populated.
Deliverable 3: Transaction History & Price Feed
Display complete transaction history per Stellar account (successful, pending, failed) via Stellar Horizon API. Integrate CoinGecko and on-chain price feeds to show real-time USD valuations for XLM and major Stellar-issued assets.
How to measure completion: Screenshot/video showing transaction history with filtering by type and date, plus real-time price display for at least 3 Stellar assets.
Deliverable 4: Transaction Simulation
Enable transaction simulation prior to MPC signing and submission, allowing users to preview transaction outcomes (estimated fees, balance changes, trustline effects) before committing. Leverages Stellar RPC simulation methods where supported.
How to measure completion: Demo showing a simulated transaction preview (with fee estimate and projected balance) displayed to the user before they approve signing.
Budget: $30,000
Deliverable 5: MPCVault Policy Engine for Stellar Transactions
Extend MPCVault's institutional policy controls to Stellar: address allowlists (approved destinations only), per-transaction and cumulative spending limits, and multi-party approval workflows (e.g., 2-of-3 approvers required above a configurable threshold). Policies are enforced at the MPC signing layer — transactions that violate policy are blocked before broadcast.
How to measure completion: Demo on Testnet showing (a) a transaction to a non-allowlisted address being rejected, (b) a transaction exceeding a spending limit being blocked, and (c) a transaction requiring 2-of-3 approval completing only after the second approver signs.
Deliverable 6: MPCVault Wallet Plugin — Stellar Classic & Soroban Signing
Ensure the MPCVault browser extension/connector works natively with Stellar Classic signing flows (SEP-0007 URI scheme, Wallet SDK patterns). Additionally, enable the connector to interact with Soroban dApps, supporting the simulate → approve → MPC sign workflow for smart contract transactions, with policy gating applied to Soroban calls.
How to measure completion: Demo showing (a) the MPCVault connector signing a Stellar Classic transaction initiated by a third-party dApp on Testnet, and (b) a Soroban smart contract interaction completing the simulate → approve → sign flow through the connector.
Deliverable 7: Automatic Asset Detection & Display
Automatically detect and display all Stellar assets held via account balances and trustlines with no manual configuration. Dynamically update as trustlines are added or removed.
How to measure completion: Demo showing a newly added trustline asset appearing in the wallet dashboard automatically without user refresh or manual entry.
Deliverable 8: Testnet Deployment & Community Feedback
Deploy full feature set on Stellar Testnet. Share testable version with Stellar developer community on Discord. Publish testnet setup instructions and collect community feedback.
How to measure completion: Public Testnet deployment link shared in Stellar Dev Discord with setup instructions. At least one round of community feedback collected and documented.
Budget: $45,000
Deliverable 9: Mainnet Production Deployment
All features from Milestones 1 and 2 fully deployed and operational on Stellar Mainnet. Production-grade infrastructure with monitoring, error handling, and failover. End-to-end validated with real XLM and issued assets.
How to measure completion: Verifiable Mainnet transactions demonstrating full wallet functionality (send/receive XLM, issued assets, trustline management, transaction simulation, policy-gated signing, Soroban interaction) on production.
Deliverable 10: API Documentation & Integration Guides
Comprehensive developer documentation for Stellar transaction building, signing, and submission via MPCVault (Classic and Soroban flows). Integration guides for enterprises and developers looking to leverage MPCVault as their Stellar custody provider.
How to measure completion: Published documentation site or repository containing API reference, quickstart guide, and at least 2 integration tutorials (one for Classic transactions, one for Soroban).
Deliverable 11: UX Readiness & Onboarding
Clear onboarding flow for new users setting up Stellar wallets within MPCVault. Functional, tested UI for all Stellar operations (send, receive, trustlines, asset management, policy configuration). In-app guidance and tooltips for Stellar-specific features (memos, trustlines, simulation). Basic usability validation with target user group (institutional clients / crypto fund operators).
How to measure completion: Onboarding flow walkthrough video. Evidence of usability validation with at least 3 target users (institutional operators). Professional user testing results (provided as part of tranche completion).
Deliverable 12: Infrastructure & Operational Readiness
Production Stellar Horizon/RPC node access, monitoring dashboards, alerting, and incident response procedures. Ensure 99.9% uptime target for Stellar signing operations.
How to measure completion: Monitoring dashboard screenshot showing live Mainnet infrastructure. Documented incident response and operational runbook.
Budget: $60,000
