Automate Recurring Payments with Blockchain Subscriptions
Create a secure and transparent subscription model using smart contracts, where users authorize recurring crypto payments and receive services without relying on centralized billing systems.Traditional subscription models rely on centralized platforms that can pause, block, or mismanage billing. A blockchain-based subscription ensures on-time, peer-to-peer payments that are secure, transparent, and free from middleman control.
Build a dApp where users can subscribe to digital services by locking crypto in a smart contract. The contract handles monthly/weekly/annual deductions and renewals automatically, while the provider gets paid instantly upon each cycle.
Recurring Smart Contract Payments
Define payment cycles and amounts in the contract, triggering automated transfers on schedule.
Subscription Plan Management
Allow service providers to create and modify plans while users select and subscribe securely.
User-Controlled Wallet Approvals
Users pre-authorize token allowances, ensuring they stay in full control of spending.
On-Chain Subscription Logs
Each transaction, renewal, and cancellation is logged immutably on the blockchain for transparency.
Service providers define subscription plans and prices. Users connect wallets, approve token spending, and subscribe. The smart contract deducts tokens on each cycle and pays the provider. All records are public and tamper-proof. Optional frontends allow viewing and managing active plans.
- Solidity contracts for managing subscriptions and periodic payments
- ERC-20 token interface for payments and allowances
- React frontend for plan selection, subscription, and cancellation
- Wallet integration using MetaMask or WalletConnect
- Chainlink Keepers for automated execution (optional)
Blockchain
Ethereum or Polygon for scalable payment execution
Smart Contracts
Solidity for recurring payment logic and subscription state tracking
Frontend
React.js + Ethers.js + Tailwind CSS for user dashboard and plan interface
Automation
Chainlink Keepers or scheduled bots to trigger payment cycles
1. Build Subscription Smart Contract
Enable plan creation, user subscriptions, and recurring payment logic with pause/cancel options.
2. Create Provider & User Dashboards
Providers list plans, users view subscriptions and toggle status via MetaMask.
3. Integrate Token Allowance Flow
Users approve limited token spending upfront using ERC-20 approve + transferFrom pattern.
4. Schedule Payment Triggers
Use Chainlink Keepers or cron bots to run periodic payment checks automatically.
5. Launch Testnet Subscription Store
Simulate real-world use cases like streaming services or SaaS tools with token payments.
Enable Seamless Subscription Services with Web3
Create a decentralized and autonomous billing model powered by smart contracts and user trust.
