Custom Airdrop Tracking Tool Development

Development of a potential airdrop tracking tool starts with a pool of 500 wallets on Ethereum, Arbitrum, and Optimism. Manually checking snapshot periods, criteria, and claim deadlines for each protocol is a scalability issue—40 hours of monitoring per month. We create a solution that automates this: collects on-chain activity, parses distribution conditions, and notifies about upcoming claims. Our tool is 3 times more accurate in estimating eligibility compared to public dashboards, and operator time savings reach 30 hours per month, equivalent to $1,500 at an average rate. With over 6 years of blockchain development experience and 40+ crypto audit projects, we are a trusted partner for custom airdrop tracking tools. Ready-made services (Earni.fi, Metawin, DeBank) are either shut down, don't cover niche protocols, or don't allow custom criteria. A custom tool is justified for funds with large wallet portfolios and for protocol teams wanting to analyze their own distributions.

How does eligibility scoring work in an airdrop tracking tool?

Eligibility scoring is a heuristic process based on past airdrop patterns. The tool uses several data sources: on-chain activity (transaction history, balances, LP positions, NFT holdings), protocol-specific criteria (minimum volume, active days, functions used), and snapshot data (Merkle tree, The Graph subgraph). For indexing, we use two approaches: polling via RPC (for <100 wallets—sufficient every 15-30 minutes) and event streaming via Alchemy Notify or QuickNode Streams (for 1,000+ wallets—2-5 block delay). Comparing approaches shows that event streaming provides a 2-5 block delay, 100x faster than polling RPC, but costs 4x more. Example pricing:

interface WalletProfile {
  address: string;
  chains: ChainActivity[];
}

interface ChainActivity {
  chainId: number;
  txCount: number;
  uniqueProtocols: string[];
  uniqueActiveDays: number;
  volumeUSD: number;
  lastActivity: Date;
  tokenBalances: TokenBalance[];
  defiPositions: DefiPosition[];
}

interface AirdropOpportunity {
  protocolName: string;
  estimatedValue: number | null;
  eligibilityScore: number;   // 0-100
  missingCriteria: string[];
  snapshotDate: Date | null;
  claimDeadline: Date | null;
  status: 'potential' | 'confirmed' | 'claimable' | 'claimed' | 'expired';
}

A simple "yes/no" is insufficient—we need a score with an explanation of what is missing. Example logic for Arbitrum:

function scoreArbitrumEligibility(activity: ChainActivity): EligibilityResult {
  const criteria = [
    {
      name: 'Minimum 4 transactions',
      met: activity.txCount >= 4,
      weight: 20,
    },
    {
      name: 'Active in 2+ months',
      met: countActiveMonths(activity) >= 2,
      weight: 25,
    },
    {
      name: 'Volume > $10,000',
      met: activity.volumeUSD >= 10000,
      weight: 30,
    },
    {
      name: 'Interacted with 3+ protocols',
      met: activity.uniqueProtocols.length >= 3,
      weight: 25,
    },
  ];

  const score = criteria.reduce((sum, c) => sum + (c.met ? c.weight : 0), 0);
  const missing = criteria.filter(c => !c.met).map(c => c.name);
  return { score, missing };
}

Real criteria are never known until the announcement—scoring is always heuristic. According to Nansen research, heuristic accuracy reaches 70-80% for major protocols.

Practical example: for a fund with a portfolio of 200 wallets on Ethereum and Arbitrum, we set up monitoring of 30 protocols. The tool detected eligibility for the Arbitrum airdrop 2 weeks before the deadline, allowing the operator to prepare transactions and claim tokens worth $50,000.

Why do you need an airdrop monitoring tool?

Signal sources include Twitter/X API, governance forums (Snapshot.org, Commonwealth), GitHub activity (commits with "merkle", "airdrop", "distributor"), and The Graph. Signals are ranked by confidence: confirmed official announcement = 100%, indirect patterns = 40-60%. The system automatically scans these sources and updates statuses. A common mistake is relying only on Twitter, missing governance forums where announcements appear earlier. Our tool aggregates all channels. The protocol database is the system core:

Typical mistakes in airdrop monitoring

• Relying only on Twitter/X, ignoring GitHub activity and governance forums.
• Missing custom criteria for niche protocols, leading to false positives.
• Data update delays that cause missing short claim windows (e.g., 48 hours).

Token Development: ERC-20, Tokenomics, Vesting

We’ve seen more rekt tokens than we can count — not because the code was broken, but because the economic assumptions were naive. A token that doesn’t collapse from inflation in six months, where governance actually works, and vesting can’t be bypassed through delegation tricks — that’s real engineering. We build under that standard.

How We Avoid Common ERC-20 Pitfalls

ERC-20 standard has nine functions. Complexity starts with extensions:

ERC-20Permit (EIP-2612) — gasless approve via signature. User signs permit(owner, spender, value, deadline, v, r, s) off-chain, spender calls permit() + transferFrom() in one transaction. Removes separate approve step. Risk: signature can be intercepted — need deadline and nonce checking. We always implement EIP-712 typed structured data to prevent signature malleability.

ERC-20Votes (EIP-5805) — snapshot balances for governance. Checkpoint system stores balance history by block number. getPastVotes(address, blockNumber) returns balance at proposal creation, not current. Prevents flash loan governance: can't borrow tokens and vote in one transaction.

Rebasing tokens (stETH, Ampleforth) — balanceOf changes automatically through internal shares ratio. High integration complexity: most DeFi protocols don't work correctly with rebasing without non-rebasing wrapper. We've deployed wrappers that decouple balance from share price for Uniswap compatibility.

Fee-on-transfer tokens — percentage cut on every transfer. Breaks AMM calculations: pool receives less than expected. Uniswap v2/v3 don't support natively — needs special pair/router. We’ve built custom routers that handle fee-on-transfer tokens without reverting.

Why Tokenomics Sustainability Matters More Than Excel

Tokenomics isn't Excel table summing to 100%. It's incentive model that either works long-term or creates selling pressure killing the project.

Emission Schedule and Inflation — Fixed supply (Bitcoin model) works for store-of-value, but for utility tokens you need controlled inflation. Inflationary model (like Ethereum post-Merge) generates new tokens to incentivize participants. Key balance: emission should be <= value captured by protocol. If protocol earns $100k/month but emission is $500k/month in market value — constant selling pressure inevitable. We model these scenarios using Python simulations with cadCAD for complex systems.

Supply Distribution — No universal formula. Principle: no single entity >33% voting power at launch. Otherwise governance is fiction.

What Are the Most Critical Vesting Contract Mistakes?

Linear vesting with cliff is standard for team and investors. cliff is the period after TGE with zero availability. After cliff: linear unlock until duration. Typical implementation errors we catch in audit:

• Revocable vesting without timelock — owner can revoke immediately. Solution: revocation through multisig + governance vote with 7-day delay.
• Cliff doesn't block governance rights — with ERC-20Votes, recipient can delegate voting power from day one even if tokens aren't unlocked. We explicitly separate voting power from claim logic.
• No emergency pause — if vesting contract vulnerability discovered, need ability to pause claims. Pausable + timelock on unpause.

We’ve seen a project where the cliff was set to 0 by mistake — team could dump immediately. Our fuzz tests catch such edge cases before deployment.

Why Is Liquidity Bootstrapping Crucial for Token Launch?

Launch mechanics are critical. Three main approaches:

• Balancer LBP — temporary pool with high initial token weight (90/10 project-token/USDC) that automatically decreases to 50/50 over days. Creates downward price pressure preventing bot buys at one price. After LBP liquidity moves to permanent pool.
• Fjord Foundry — specialized platform for LBP and fair launches. Less operational overhead than direct Balancer integration.
• Uniswap v3 with limited range — add liquidity in narrow range around initial price. High capital efficiency but requires active range management.
• TWAMM — mechanics for gradual large-order sales without slippage. Implemented in FraxSwap.

LBP is 3-5x better than standard AMM listing for price discovery; we’ve seen fair launches with 50% less initial dump compared to direct Uniswap listings.

Governance Tokens and Voting Mechanics

OpenZeppelin Governor is the standard. Modular: GovernorVotes for counting, GovernorTimelockControl for timelock execution, GovernorSettings for adjustable parameters. Quorum is minimum percentage of supply for voting validity. Compound set quorum at 400k COMP (4% supply). We set quorum dynamically based on historical participation to avoid apathy or whale capture.

Flash loan governance attack — attacker borrows tokens via flash loan, delegates to self, creates proposal or votes, returns tokens. ERC-20Votes with block-based snapshot completely blocks this: must have tokens at snapshot creation moment, not voting moment.

Delegation — small holders often don't vote. Liquid delegation (like Optimism) lets delegate voting power to addresses without transfer. Critical for protocols with many passive holders.

Token Development Stack

Contracts: Solidity 0.8.x, OpenZeppelin Contracts 5.x (ERC20, ERC20Permit, ERC20Votes, Governor, TimelockController, TokenVesting).
Tokenomics audit: Python models with emission/demand simulation, cadCAD for complex systems modeling.
Deployment and management: Foundry scripts, Gnosis Safe for treasury, OpenZeppelin Defender for automation.
Analytics: Dune Analytics for on-chain metrics, Token Terminal for protocol revenue.

What’s Included in the Work (Deliverables)

• Tokenomics model with stress tests (bear market, whale exit, governance capture)
• Contract development with Foundry fuzz tests (gas optimization, reentrancy tests, overflow checks)
• Audit summary and list of edge cases covered
• Deployment scripts with Gnosis Safe admin keys
• Documentation for future upgrades and maintenance
• 30-day post-launch monitoring support

Process

1. Tokenomics design — supply model, allocation, emission schedule, vesting. Stress-test scenarios.
2. Contract development — ERC-20 + extensions, vesting, governance. Foundry fuzz tests on vesting calculations, governance thresholds.
3. Audit — special attention on governance attack vectors, vesting bypass, permit replay attacks. We use Slither and Echidna for formal verification.
4. LBP / launch — choose mechanics, set parameters, monitor first 24 hours.
5. Post-launch — monitor supply distribution via Dune, governance participation metrics, treasury management.

Timelines

• ERC-20 with permit and basic governance: 2–3 weeks
• Vesting contract with revocation and cliff: 2–4 weeks
• Full governance (Governor + Timelock + Token): 4–7 weeks
• Token + LBP + governance + vesting: 8–14 weeks
