Hackathon Track

Built for AlgoBharat Hack Series 3.0, targeting the Agentic Commerce track, specifically the A2A Autonomous Payments and A2A Agentic Commerce Framework categories.

(<a href="#readme-top">back to top</a>)

About The Project

<div align="center"> <table> <tr> <td align="center"><img src="screenshots/landing-page.png" alt="Landing Page" width="420"> Landing Page</td> <td align="center"><img src="screenshots/dashboard.png" alt="Dashboard" width="420"> Dashboard</td> </tr> <tr> <td align="center"><img src="screenshots/subscriptions.png" alt="Subscriptions" width="420"> Subscriptions</td> <td align="center"><img src="screenshots/escrow-vaults.png" alt="Escrow Vaults" width="420"> Escrow Vaults</td> </tr> </table> </div>

Most subscription trackers are just spreadsheets with a nicer font. They show you what you spend, but they cannot do anything about it. Unsubscribely puts your subscriptions on-chain. You lock funds in an escrow vault you own, an autonomous agent releases payments on billing day, and every transaction is verifiable on Algorand.

Here is why this is different:

<kbd>Lock</kbd> funds in a smart contract vault - your keys, your control, kill switch on everything
<kbd>Agent</kbd> releases vaults on billing day every 30 min on Railway, no LLM needed
<kbd>MCP</kbd> Server with 12 tools - connect Claude, ChatGPT, or any AI to manage your subscriptions
<kbd>Telegram</kbd> bot (@unsublyybot) - cancel by voice/text, get alerts 3 days before renewal
<kbd>Gmail</kbd> auto-import - sign in with Google, we detect your subscriptions from receipts
<kbd>Tinyman</kbd> DEX swap integration + <kbd>Gora</kbd> Oracle ALGO/USD price feeds
<kbd>Proofs</kbd> on-chain cancellation proofs - immutable evidence you cancelled

[!NOTE] The average Indian developer pays for 8-12 SaaS tools in USD, losing 5-7% to forex markup per transaction. Unsubscribely eliminates this with sub-penny on-chain settlement on Algorand.

Deployed contracts Algorand TestNet

Contract	App ID	Explorer
ServiceRegistry <sub>A2A discovery, 5 services seeded</sub>	<samp>759205676</samp>	Lora
AgentEscrowVaultV2 template <sub>Box-storage billing history</sub>	<samp>759205677</samp>	Lora

Autonomous agent wallet: <samp>RVHOYLPY4L47JYCYEMCP7EMEC2AZ3HV53YHSL2ZISX6PSO5EQ6H5YVAE5U</samp>

Per-user vaults (Standard, AgentV2, Time-Lock, Multi-Sig, Dispute, ASA, Cancellation Insurance) are deployed on demand from the dashboard. MainNet singletons are not yet deployed. The app shows clear guards on mainnet for ServiceRegistry-dependent UIs.

[!IMPORTANT] Security: Smart contracts are compiled with AlgoKit/PuyaPy and tested on TestNet. A formal third-party security audit is planned before any MainNet deployment with real user funds. All contracts are open source for community review.

Getting Started

To get a local copy up and running, follow these steps.

[!TIP] The web app works fully without the agent running. You can browse, add subscriptions, connect a wallet, and create vaults without any Railway or Telegram setup. The agent only adds autonomous vault releases.

Prerequisites

Node.js 20 or later
A Supabase project. Create a free one at supabase.com
Pera Wallet on Algorand Testnet. Download Pera, switch to Testnet in settings, then get free test ALGO from the Algorand Testnet Faucet
Python 3.12 + AlgoKit - only needed if you want to recompile contracts (pre-compiled artifacts are already included)
```
pip install algokit
```

[!TIP] No wallet? The app is fully browsable without connecting Pera. You only need a wallet to deploy escrow vaults or sign transactions.

Installation

Clone the repo

git clone https://github.com/devndesigner6/unsubly.git
cd unsubly

Install dependencies
```
npm install
```
Set up environment variables
```
cp .env.example .env
```
Open .env.example first - every variable is documented with comments and a generation command. At minimum fill in:
- VITE_SUPABASE_URL and VITE_SUPABASE_PUBLISHABLE_KEY from Supabase, Settings, API
- SUPABASE_SERVICE_ROLE_KEY from Supabase, Settings, API (service_role key)
- CEREBRAS_API_KEY from cloud.cerebras.ai - powers AI Chat page and Telegram bot
- AGENT_WALLET_MNEMONIC and VITE_AGENT_WALLET_ADDRESS - generate with the one-liner in .env.example
Run the database schema (first time only)
- Go to your Supabase project, SQL Editor
- Paste the contents of supabase/migrations/FULL_SCHEMA_SETUP.sql and run it
- This file exists at the root of the migrations folder and creates all tables, RLS policies, and indexes in one shot
Start the dev server
```
npm run dev
```
App runs at http://localhost:5000

Mac users: port 5000 conflicts with AirPlay Receiver. Either disable AirPlay (System Settings, AirDrop & Handoff) or change the port in vite.config.ts and package.json scripts to 5001.

Run the test suite

npx vitest run                          # frontend unit tests
cd smart_contracts && pytest tests/      # smart contract tests

Production build and serve
```
npm run build
npm run start
```

<details open> <summary>Running the real OpenClaw agent locally</summary>

The production agent is a real OpenClaw Gateway workspace, separate from the web app. OpenClaw owns the runtime and cron schedule; the existing Unsubscribely vault code is exposed through the unsubscribely_vault_monitor workspace skill.

cd agents/openclaw
npm install
npm run start

Create agents/openclaw/.env or export these values before starting:

AGENT_WALLET_MNEMONIC=your_25_word_mnemonic
SUPABASE_URL=https://your-project-id.supabase.co
SUPABASE_SERVICE_ROLE_KEY=your_service_role_key
TELEGRAM_BOT_TOKEN=your_telegram_bot_token
TELEGRAM_CHAT_ID=your_telegram_chat_id
ALGO_NETWORK=testnet
SERVICE_REGISTRY_APP_ID_TESTNET=759205676
OPENCLAW_MODEL=google/gemini-2.0-flash
OPENAI_API_KEY=your_model_provider_key

npm run start writes an OpenClaw config, seeds a recurring OpenClaw cron job named Unsubscribely vault monitor, and starts openclaw gateway run. The cron job runs every 30 minutes and tells OpenClaw to execute npm run monitor:vaults from this workspace.

For a direct deterministic check without the Gateway, run:

npm run monitor:vaults

</details>

<details open> <summary>Optional: recompile smart contracts or deploy to testnet</summary>

Recompile contracts (pre-compiled artifacts are already included):

algokit compile py smart_contracts/escrow/contract.py
algokit compile py smart_contracts/agent_escrow/contract.py
algokit compile py smart_contracts/agent_escrow_v2/contract.py
algokit compile py smart_contracts/service_registry/contract.py
algokit compile py smart_contracts/time_locked/contract.py
algokit compile py smart_contracts/multi_sig/contract.py
algokit compile py smart_contracts/dispute/contract.py
algokit compile py smart_contracts/asa_escrow/contract.py

Deploy singleton contracts (requires a funded testnet account):

TESTNET_MNEMONIC="..." node scripts/deploy.js

</details>

<details open> <summary>Troubleshooting</summary>

Problem	Fix
Wallet not connecting	Make sure Pera Wallet is set to Testnet (Settings, Developer Settings, Node Configuration)
"Recipient has not opted in" error	The recipient address must have received at least 1 ALGO before a vault can pay them. Send a small amount first from the faucet
Agent wallet balance too low	Fund the agent wallet at bank.testnet.algorand.network. It needs ALGO to pay transaction fees
AI Chat returns error	Check that `CEREBRAS_API_KEY` is set in your `.env` and valid at cloud.cerebras.ai
Supabase RLS errors	Make sure you ran `FULL_SCHEMA_SETUP.sql` in the SQL Editor. Missing tables cause silent 403s
x402 payment rejected	Ensure `X402_PAY_TO_ADDRESS` matches `VITE_AGENT_WALLET_ADDRESS` or leave both blank to disable x402 in dev

How It Works

1. <kbd>Lock</kbd> - Add a subscription and deploy an escrow vault from the dashboard. Choose from 7 vault types: <samp>Standard</samp>, <samp>AgentV2</samp>, <samp>Time-Lock</samp>, <samp>Multi-Sig</samp>, <samp>Dispute</samp>, <samp>ASA</samp>, or <samp>Cancellation Insurance</samp>. Your ALGO sits in a contract you own.

2. <kbd>Release</kbd> - OpenClaw checks every 30 minutes. When a billing date hits, it verifies the recipient against the on-chain ServiceRegistry, checks your spending guardrails, and calls <samp>release()</samp> on the contract. Funds go directly on-chain. You get a Telegram notification with the transaction ID.

3. <kbd>Prove</kbd> - Mint an ARC-3 NFT receipt after each release. AgentEscrowVaultV2 also writes an immutable <samp>BillingRecord</samp> into Box Storage per cycle, giving you a full on-chain billing history.

(<a href="#readme-top">back to top</a>)

Usage

Sign up at unsubly.xyz - free, no credit card.
Add subscriptions manually, import CSV, or sign in with Google for auto-detection.
Connect Pera/Defly wallet ? create an escrow vault ? fund it with ALGO.
Connect Telegram (@unsublyybot) in Settings for renewal alerts and voice commands.
The agent runs every 30 min - releases vaults on billing day, notifies you via Telegram.
To cancel: say "cancel spotify" in Telegram, follow instructions, reply "done" - vault killed, ALGO returned.
Connect your AI agent (Claude/ChatGPT) from the Connect Agent page to manage subscriptions via MCP.

(<a href="#readme-top">back to top</a>)

Business Model

<kbd>Phase 1</kbd> current - Free for users. Revenue from x402 micro-payments: external AI agents pay 0.001 ALGO per API call to access subscription data. No API keys, no subscriptions needed. Payment IS the credential.

<kbd>Phase 2</kbd> post-audit - Mainnet launch. Premium MCP access ($5/mo for write+admin scope). ServiceRegistry listing fee (one-time ALGO payment for service providers to publish).

<kbd>Phase 3</kbd> - B2B vault infrastructure. Companies use escrow contracts for employee subscription procurement. Agent handles vendor payments autonomously.

Target users: Indian developers and freelancers (25-35) managing 8-12 SaaS tools (Notion, GitHub, Cursor, Figma) totaling $50-150/month in USD, losing 5-7% to forex fees per transaction.

Why Algorand: <samp>3.3s finality</samp> � <samp>sub-penny fees</samp> � ARC-4 ABI for clean contract interfaces � Box Storage for on-chain history � instant settlement without L2 complexity.
