?proof=` so the candidate passport can show a known proof without pretending wallet-wide credential discovery exists yet. Issuer registration now explains approval readiness before signing, and `/pilot` keeps the first rollout bounded to a small testnet issuer pilot. Employer proof packs include a recruiter-safe summary plus an unsigned standards-alignment preview for W3C VC 2.0 and Open Badges 3.0 mapping. That preview is not a signed standards credential yet.\n\n---\n\n## 30-Second Pitch\n\n**Problem:** Bootcamp certificates are PDFs that anyone can fake and no one can independently verify. Employers skip verification or pay for a background check service.\n\n**Solution:** Stellaroid Earn anchors credential hashes on a Soroban smart contract where approved issuers register and verify certificates, anyone checks proof at a public URL with no login, and employers pay graduates in XLM on Stellar testnet, all on-chain.\n\n**Why Stellar:** Sub-cent fees and 5-second finality make issuing credentials cheap enough that skipping it makes no sense. `simulateTransaction` lets anyone verify with zero wallet setup. Native XLM via SAC closes the loop from proof to payout on one chain.\n\n![From proof to payment: register, verify, read, fund, approve, release](https://raw.githubusercontent.com/Iron-Mark/Hackathon-Stellaroid_Earn/main/images/proof-to-payment-flow.png)\n\n---\n\n## Feature Gallery\n\n\n\n\n\n\n\n\n\n\n

Suspended issuers are blocked on-chain\n- **Two read paths**: server-side RSC with `revalidate=60` (CDN-cached proof pages) + client-side `simulateTransaction` (dashboard state)\n- **One write path**: Freighter signs → `sendTransaction` → poll for result\n- **CSP** locks `connect-src` to `*.stellar.org` and the WalletConnect relay - no other third-party origins\n\n---\n\n## Contract Integration (Frontend to Soroban)\n\nThe frontend talks to the deployed `stellaroid_earn` contract with **`@stellar/stellar-sdk`**. The client lives in [`frontend/src/lib/contract-client.ts`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/frontend/src/lib/contract-client.ts) (writes + client-side reads) and [`frontend/src/lib/contract-read-server.ts`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/frontend/src/lib/contract-read-server.ts) (server-rendered proof pages). The SDK is lazy-loaded so its multi-megabyte bundle stays out of every route's first load.\n\n```ts\n// frontend/src/lib/contract-client.ts\nimport type * as StellarSdk from \"@stellar/stellar-sdk\";\n\n// Lazy-load the SDK once, on the first contract read or wallet action.\nconst getSdk = () => import(\"@stellar/stellar-sdk\");\n\n// READ (no wallet): simulate an invocation against Soroban RPC.\nconst server = new sdk.rpc.Server(appConfig.rpcUrl);\nconst sim = await server.simulateTransaction(tx);\nconst value = sdk.scValToNative(sim.result.retval);\n\n// WRITE: build with TransactionBuilder, wallet signs, submit + poll.\nconst tx = new sdk.TransactionBuilder(account, {\n fee: sdk.BASE_FEE,\n networkPassphrase: getExpectedNetworkPassphrase(),\n})\n .addOperation(\n sdk.Operation.invokeContractFunction({\n contract: appConfig.contractId, // NEXT_PUBLIC_SOROBAN_CONTRACT_ID\n function: method, // e.g. \"verify_certificate\"\n args, // sdk.nativeToScVal(...) per argument\n }),\n )\n .setTimeout(30)\n .build();\n\nconst signedXdr = await wallet.sign(tx.toXdr()); // Freighter / Albedo / Stellar Wallets Kit\nconst sent = await server.sendTransaction(sdk.TransactionBuilder.fromXdr(signedXdr, passphrase));\nconst result = await server.pollTransaction(sent.hash);\n```\n\nEvery public contract function has a matching typed wrapper in the client. The wrapper passes the exact contract function name to `Operation.invokeContractFunction`:\n\n| Contract function (`contracts/stellaroid_earn/src/lib.rs`) | Frontend wrapper (`contract-client.ts`) |\n| --- | --- |\n| `register_issuer` | `registerIssuer()` |\n| `approve_issuer` | `approveIssuer()` |\n| `suspend_issuer` | `suspendIssuer()` |\n| `get_issuer` | `getIssuer()` (read / `simulateTransaction`) |\n| `register_certificate` | `registerCertificate()` |\n| `verify_certificate` | `verifyCertificate()` |\n| `get_certificate` | `getCertificate()` (read / `simulateTransaction`) |\n| `revoke_certificate` | `revokeCertificate()` |\n| `suspend_certificate` | `suspendCertificate()` |\n| `reward_student` | `rewardStudent()` |\n| `link_payment` | `linkPayment()` |\n| `create_opportunity` | `createOpportunity()` |\n| `fund_opportunity` | `fundOpportunity()` |\n| `submit_milestone` | `submitMilestone()` |\n| `approve_milestone` | `approveMilestone()` |\n| `release_payment` | `releasePayment()` |\n| `refund_opportunity` | `refundOpportunity()` |\n| `get_opportunity` | `getOpportunity()` (read / `simulateTransaction`) |\n\nThe network passphrase in `NEXT_PUBLIC_STELLAR_NETWORK_PASSPHRASE` must match the network the contract is deployed on (testnet), or the wallet rejects the signature.\n\n---\n\n## Quick Start\n\n### Prerequisites\n\n- Rust (stable) + `wasm32v1-none` target\n- [Stellar CLI v26+](https://developers.stellar.org/docs/tools/stellar-cli)\n- Node.js 20+ and npm\n- [Freighter](https://www.freighter.app/) browser extension set to **Testnet**\n\nFull setup guide: [`docs/reference/pre-workshop-setup-guide.pdf`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/reference/pre-workshop-setup-guide.pdf)\n\n### Smart Contract\n\n```bash\ncd contracts/stellaroid_earn\nmake test # cargo test (contract suite)\nmake build # builds wasm32v1-none target\n\n# Deploy to testnet\nstellar keys generate my-key --network testnet --fund\nstellar contract deploy \\\n --wasm target/wasm32v1-none/release/stellaroid_earn.wasm \\\n --source my-key --network testnet\n```\n\nCI runs the contract gate with `cargo test -p stellaroid_earn --locked` and `cargo build -p stellaroid_earn --target wasm32v1-none --release --locked` in [`Contract CI`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/.github/workflows/contract-ci.yml).\n\n### Frontend\n\n```bash\ncd frontend\ncp .env.example .env.local # fill in contract ID + read address\nnpm install\nnpm run dev # http://localhost:3000\n```\n\n**Environment variables** (`.env.local`):\n\n```env\nNEXT_PUBLIC_STELLAR_RPC_URL=https://soroban-testnet.stellar.org\nNEXT_PUBLIC_STELLAR_NETWORK=TESTNET\nNEXT_PUBLIC_STELLAR_NETWORK_PASSPHRASE=Test SDF Network ; September 2015\nNEXT_PUBLIC_SOROBAN_CONTRACT_ID=\nNEXT_PUBLIC_STELLAR_ADMIN_ADDRESS=\nNEXT_PUBLIC_STELLAR_READ_ADDRESS=\nNEXT_PUBLIC_SOROBAN_ASSET_ADDRESS=CDLZFC3SYJYDZT7K67VZ75HPJVIEUVNIXF47ZG2FB2RMQQVU2HHGCYSC\nNEXT_PUBLIC_SOROBAN_ASSET_CODE=XLM\nNEXT_PUBLIC_SOROBAN_ASSET_DECIMALS=7\nNEXT_PUBLIC_STELLAR_EXPLORER_URL=https://stellar.expert/explorer/testnet\nNEXT_PUBLIC_CANONICAL_URL=https://stellaroid.tech\n```\n\n---\n\n## Verifiable On-Chain\n\nEvery action in the demo flow is a real transaction on Stellar testnet.

Public browser clients do not automatically send signed XDR to `/api/fee-bump`.\n\n**How it works:**\n\n1. A trusted server obtains a user-signed transaction for an allowed Stellaroid Earn method\n2. The trusted server calls `/api/fee-bump` with `Authorization: Bearer `\n3. The route enforces XDR size, signature, operation count, network, contract ID, method allow-list, and fee-ceiling checks\n4. Only then does the sponsor key wrap the transaction as a fee bump\n\n**Implementation:**\n- Server route: [`frontend/src/app/api/fee-bump/route.ts`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/frontend/src/app/api/fee-bump/route.ts)\n- Request policy: [`frontend/src/lib/fee-bump-policy.ts`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/frontend/src/lib/fee-bump-policy.ts)\n- Config: `FEE_SPONSOR_SECRET` + `FEE_SPONSOR_TOKEN` are server-only. Public browser auto-sponsorship stays disabled; trusted server callers must provide the bearer token explicitly.\n- Browser fallback: normal user-paid Freighter transactions remain the default path.\n\n---\n\n## Metrics & Monitoring\n\n- **Status metrics:** [`/status#metrics`](https://stellaroid.tech/status#metrics) - public contract-event evidence, proof hashes, reward/payment events, and source labels on the operational status page\n- **Health endpoint:** [`/api/health`](https://stellaroid.tech/api/health) - cached JSON health check (config, RPC latency, contract availability)\n- **Events API:** [`/api/events`](https://stellaroid.tech/api/events) - structured contract event data for external consumers\n- **Events stream:** [`/api/events/stream`](https://stellaroid.tech/api/events/stream) - short-lived Server-Sent Events stream for live demo refreshes without adding a database\n- **MCP server:** [`/api/mcp`](https://stellaroid.tech/api/mcp) - read-only remote Model Context Protocol endpoint (Streamable HTTP, no auth) so AI agents can verify credentials, inspect issuers, and browse escrowed paid trials; built on Vercel's `mcp-handler` + the official MCP TypeScript SDK\n- **Vercel Analytics:** Page analytics plus privacy-safe custom events for proof sharing, proof-pack downloads, employer handoff, shortlist saves, and escrow-start actions\n\n![On-chain metrics panel with indexed contract events and the live activity feed](https://raw.githubusercontent.com/Iron-Mark/Hackathon-Stellaroid_Earn/main/images/status-onchain-metrics.png)\n\n### Data Indexing\n\nContract events are read from two public sources. The app first queries Soroban RPC `getEvents` for recent contract events, then supplements that result with Stellar Expert's public contract event index so older testnet activity does not disappear from the demo surface when the RPC retention window moves on. Events are decoded from ScVal/XDR where possible, categorized by kind (`cert_reg`, `cert_ver`, `reward`, `payment`), deduplicated, source-labelled, and served through `/api/events`, `/api/events/stream`, plus `/status#metrics`.\n\nThis remains a lightweight serverless evidence layer, not a full analytics warehouse. Vercel page analytics and custom events help inspect proof/share/employer flow interest without storing raw wallet addresses or proof hashes; durable proof history, issuer conversion, and long-term product analytics still require a first-party read model.\n\n---\n\n## Tech Stack\n\n| Component | Version |\n|---|---|\n| Soroban SDK | 26.1.0 |\n| Stellar CLI | 26+ |\n| Next.js | 15 (App Router) |\n| React | 19 |\n| @stellar/stellar-sdk | latest |\n| @stellar/freighter-api | latest |\n| @albedo-link/intent | latest |\n| Tailwind CSS | v4 |\n| PWA | manifest + service worker + iOS splash set |\n\n---\n\n## Project Structure\n\n```\nstellaroid-earn/\n├── Cargo.toml # Rust workspace (Soroban contract)\n├── contracts/\n│ └── stellaroid_earn/\n│ ├── src/\n│ │ ├── lib.rs # Soroban credential + payment contract\n│ │ └── test.rs # contract security and lifecycle tests\n│ ├── Makefile # build / test / fmt / clean targets\n│ └── Cargo.toml\n├── frontend/\n│ ├── src/\n│ │ ├── app/ # Next.js App Router pages\n│ │ │ ├── app/ # Participant dashboard (issuer + employer)\n│ │ │ ├── issuer/ # Issuer registration + lookup\n│ │ │ └── proof/[hash]/ # Public shareable verified badge\n│ │ ├── components/ # UI components (proof card, wallet, badges)\n│ │ ├── hooks/ # Freighter wallet state\n│ │ └── lib/ # Contract client, RPC helpers, types\n│ └── .env.example\n├── docs/ # Product docs, setup references, operations, and archives\n├── demo/ # Demo script, FAQ, press kit\n├── images/ # README screenshots\n├── scripts/ # Screenshot capture and operations scripts\n├── LICENSE\n└── README.md\n```\n\n---\n\n## Demo Video\n\n**Campaign cut (2026-08):** [`assets/campaign/stellaroid-promotional-demo.mp4`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/assets/campaign/stellaroid-promotional-demo.mp4)\n\n> Two-minute live-site walkthrough of stellaroid.tech with voice-over: landing, wallet-less `/demo` tour, verified proof, employer handoff, and the opportunity directory.

That total is two groups: **30 independent participant wallets** from the testnet review, plus **32 controlled QA accounts that I operate myself** for structured product verification (24 from the July guided cohort, plus 8 from the August QA wave). Both groups are listed in full below and every wallet and transaction links to Stellar Expert.\n\nThe 32 QA accounts are disclosed as QA personas, not as independent people. So the figure above is wallet-account coverage with real network activity. It is not a claim of 62 separate users, and the independent participant count remains 30. A prior snapshot of this figure was 54 (30 independent plus 24 QA).\n\n### Testnet Wallet Evidence\n\n30 independent participant wallet addresses from the Stellar testnet review are listed for public review. Each wallet address is verifiable on [Stellar Expert](https://stellar.expert/explorer/testnet). Some wallets have direct contract interactions such as `register_issuer`; others are funded participant wallets used during the review flow. The committed feedback snapshot keeps participant names and emails redacted.\n\n

\n\nThe 32 QA account addresses that complete the 62-account total are listed separately in the [guided QA evidence log](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/operations/guided-qa-cohort-2026-07.md) (24 July accounts) and the [August 2026 QA wave log](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/operations/guided-qa-wave-2026-08.md) (8 additional accounts I operate), so each group stays checkable on its own.\n\n\n| # |

\n\n### Guided Testnet QA Coverage\n\nAlongside the independent participant review, 24 controlled QA accounts I operate completed eight structured issuer, graduate, and employer journeys on the public testnet contract. The run produced 64 QA-account-signed transactions plus eight facilitator approvals, including eight verified credentials and eight released 1 testnet XLM paid opportunities (no monetary value).\n\nThe [guided QA evidence log](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/operations/guided-qa-cohort-2026-07.md) links every July public account and transaction. In August 2026 I added 8 more QA accounts I operate, logged in [guided-qa-wave-2026-08.md](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/operations/guided-qa-wave-2026-08.md). Those 8 are not independent participants. Combined QA coverage is 32 accounts I operate. The organization, credential, cohort, and opportunity names are fictional scenario data. All 32 QA accounts are included in the 62-account testnet coverage total and identified by their QA purpose in the evidence logs.\n\n### Feedback Collection\n\n- **Google Form:** [Stellaroid Earn - User Feedback Form](https://docs.google.com/forms/d/e/1FAIpQLSftFt8grSRUPecRVQWSRROLA8DAUOn4T61CrZQHtPQaMTxaWw/viewform)\n- **Response export (Excel):** [`docs/planning/user-feedback-responses.xlsx`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/planning/user-feedback-responses.xlsx) (plain-text CSV also committed: [`user-feedback-responses.csv`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/planning/user-feedback-responses.csv))\n- **Full feedback documentation:** [`docs/planning/user-feedback.md`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/blob/main/docs/planning/user-feedback.md)\n\n### Improvements Based on Feedback\n\nEvery improvement below maps to a piece of pilot feedback and the commit that shipped it:\n\n| Feedback | Improvement | Commit |\n|----------|-------------|--------|\n| \"Issuer vs Employer toggle was confusing at first\" | Contextual role guidance hints below the persona toggle | [`c1450bf`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/commit/c1450bf) |\n| \"Not clear which role to pick after connecting wallet\" | Fresh-state hint now shows what *both* roles do, so a new user can choose | [`09c9d45`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/commit/09c9d45) |\n| \"Would like to see transaction history in the dashboard\" | Added a wallet-scoped \"Activity involving your wallet\" panel on `/app` | [`fa0c5d0`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/commit/fa0c5d0) |\n| \"Mobile support would be great for checking proofs on the go\" | Mobile-first redesign, installable PWA, and WalletConnect mobile signing | [`145f6ad`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/commit/145f6ad) |\n| \"Would be nice to have a list of all credentials I've issued\" | Clarified where issued credentials surface, with a link to full account history | [`eb181b8`](https://github.com/Iron-Mark/Hackathon-Stellaroid_Earn/commit/eb181b8) |\n\n---\n\n## Community Contribution\n\n[![Threads Post](https://img.shields.io/badge/Threads-@iron__markk-000000?style=flat-square&logo=threads&logoColor=white)](https://www.threads.com/@iron_markk/post/DXeJNnlkgLF)\n\n---\n\n## Built By\n\n**Mark Siazon** - Hybrid Product Designer & Full-Stack Developer\n\n[![Portfolio](https://img.shields.io/badge/Portfolio-marksiazon.dev-F59E0B?style=flat-square&logo=vercel&logoColor=white)](https://www.marksiazon.dev/)\n[![LinkedIn](https://img.shields.io/badge/LinkedIn-Mark_Siazon-0A66C2?style=flat-square&logo=linkedin&logoColor=white)](https://www.linkedin.com/in/mark-siazon/)
