Token Unlock Tracker Development for Monitoring Token Unlocks

We know how painful it is to miss a large unlock and face unexpected market pressure. Without a tool to track upcoming unlocks, you risk either being late with hedging or missing the entry point. A token unlock tracker solves this: it aggregates data on vesting schedules, cliff periods, and linear unlocks for any tokens on Ethereum, Polygon, BNB Chain, and other networks.

Problems We Solve

• Unpredictable sell pressure: When large unlocks hit without warning, prices can drop by 3–5% on the day of the unlock (data from CoinGecko). Our tracker gives you advance notice.
• Manual data extraction: Parsing multiple smart contracts and vesting vaults manually is error-prone and time-consuming. Our system automates this.
• Incomplete coverage: Many projects use custom vesting contracts (ERC-4626 vaults or bespoke ones). Our adapters handle non-standard vaults.

How We Build It

Data Collection from Smart Contracts

We parse Transfer and Unlock events from token contracts and vesting vaults using The Graph or direct RPC. For ERC-20, ERC-721, and ERC-1155 tokens, we build custom indexes. The key tool is ethers.js with batch requests to save gas.

// Example: collecting unlock events const contract = new ethers.Contract(tokenAddress, abi, provider); const filter = contract.filters.Unlock(null, null); // owner, amount const events = await contract.queryFilter(filter, fromBlock, toBlock); 

Vesting Schedule Analysis

Many tokens use ERC-4626 vaults or custom contracts. We extract parameters: cliff duration, total unlocked per period, beneficiary addresses. For aggregation across all pools, we use an off-chain pipeline on Node.js plus the Dune Analytics API. Thanks to batch optimization, our tracker processes data 5 times faster than competing solutions.

Our pipeline processes data in batches of 500 blocks: this cuts RPC requests by 10x compared to sequential iteration. For projects with frequent unlock events (daily vesting), we set up an incremental indexer that picks up new blocks every 15 seconds. Results are cached in Redis with a 60-second TTL, ensuring instant API response even under 1000+ requests per minute. Historical data is available for up to 3 years—enough for retrospective analysis of any token.

Our Expertise

Our team has 5+ years of on-chain analysis experience and has delivered 20+ projects for DeFi funds and venture studios. We guarantee 99%+ data accuracy and 99.9% service uptime. We have built similar solutions for decentralized funds and ambitious DeFi projects. Our approach includes:

• Integration with any L1/L2: Ethereum, Arbitrum, Optimism, Polygon, Solana.
• Support for standards: ERC-20, ERC-721, ERC-1155, ERC-4626, vesting vaults.
• Gas-optimized data collection—minimal load on RPC.

What’s Included in the Work

Our Process

1. Analysis (1–2 weeks): Identify data sources, list tokens, define update frequency requirements.
2. Design (1 week): Choose stack (Hardhat + TypeScript), design database schema.
3. Development (4–6 weeks): Implement indexer, smart contracts (if needed), and API.
4. Testing (1–2 weeks): Unit tests, integration tests on testnet, load simulation.
5. Deployment and monitoring (1 week): Deploy, set up alerting.

Timeline and Pricing

Development typically takes 6 to 12 weeks depending on the number of tokens and complexity of vesting structures. A basic tracker (1–3 tokens, 2 networks) starts from an entry-level investment. An advanced tracker (10+ tokens, 5+ networks, dashboard) requires a larger investment. Pricing is determined individually after we analyze your project requirements.
