You farmed it for eight months.
A clustering script needed eight seconds to call you a bot.

That's how 803,093 LayerZero wallets found out — after the snapshot, when nothing could be fixed. Predrop runs the same classes of checks on your wallets before the snapshot does: what you actually hold, which streaks are at risk, which of your wallets would get clustered together, and which claim deadline is about to burn your allocation.

Every other tool works after the snapshot. That's too late.

Drops, Earndrop, and Earnifi (public pricing: $21–39/mo) tell you what you can claim once a snapshot has happened — when every positioning decision is already locked in. Predrop works on the other side of the timeline, while you can still fix things.

[flagship] sybil self-audit

"Would I get flagged?" — run the filters on yourself first

A sybil is one person pretending to be many wallets — projects scan for this and disqualify entire clusters. Predrop applies the same classes of heuristics the hunters use — shared-funder clustering, CEX-withdrawal lineage, synchronized transaction timing — to your own addresses, and shows you exactly which links would group them. LayerZero flagged 803,093 addresses; Linea cut ~40% of claimants. Find your flags while there's still time to restructure: predrop sybil audit.

[footprint score]

One number to check every morning

The Footprint Score, 0–100: streak consistency (40%), position coverage (25%), sybil risk inverted (25%), deadline hygiene (10%) — with a sparkline of its history. When it drops, the dashboard tells you exactly why and what fixes it.

[verify]

What you actually hold

Direct balanceOf checks across chains for your receipt tokens — the token a protocol gives you as proof you deposited; holding it is your on-chain attendance record. Not "you interacted once in 2024." Provable holdings, right now.

[streaks]

Streaks, milestones, decay alerts

2026 allocation criteria reward consistency over intensity. Predrop tracks per-protocol streaks with milestones at 7/30/90/180 days — and "streak at risk" is the loudest alert in the product, because a lapse can reset months of footprint.

[deadlines]

Claim-deadline dead-man's-switch

Escalating local alerts as claim windows close. Sonic burns 32.69M unclaimed S on Oct 15, 2026 — permanent, on-chain, no recovery. Nobody should donate a year of farming to a burn address by forgetting.

[points-pnl]

Points P&L ledger

Gas plus capital-lockup cost vs. realistic point value per farm — "$41 spent vs $0 realizable" gets a blunt kill this farm? flag. Stop paying rent on dead programs.

[share]

A footprint card worth posting

predrop brief --share generates a masked snapshot of your score and streaks — addresses always shortened to 0x12…ab, never the full wallet list. Brag without doxxing your cluster.

// for everyone

Never used a terminal? You're three lines away.

Predrop is a command-line tool with a friendly local dashboard. If you can copy and paste, you can run it. Here's the whole setup, honestly.

The entire quickstart

Install Node.js first if you don't have it (one installer from nodejs.org, version 20 or newer). Then open your terminal — Terminal on Mac, PowerShell on Windows — and paste these three lines, one at a time:

npm install -g predrop
predrop wallets add 0xYourPublicAddress
predrop scan

That's it. predrop serve opens your dashboard at localhost:4179. Want to look around with sample data before adding a real address? npx predrop demo — no install, nothing saved to your real setup.

Stuck at any point: predrop doctor checks your setup and tells you what to fix, in plain English.

What this does — and what it never does

PREDROP DOES

  • Read public blockchain data about addresses you paste in — the same data anyone can see on a block explorer
  • Store everything in local files on your computer
  • Show you streaks, flags, deadlines, and a score — locally

PREDROP NEVER

  • Asks for a private key, seed phrase, or wallet connection — there is no place to even type one
  • Signs or sends a transaction — it is structurally incapable of moving funds
  • Uploads your wallet list to Predrop or any product server — local files stay local

If any tool asks for your seed phrase to "check your airdrops," close the tab. That's the scam this design makes impossible.

// three steps

Install → scan → act

Your first full footprint audit in a few minutes. Bring your own RPC endpoints or use public ones.

step 1 / install

Install

One package on your own machine — or take the demo for a spin first.

$ npm install -g predrop
# or, sample data, no install:
$ npx predrop demo
step 2 / scan

Add wallets & scan

Paste public addresses. Predrop verifies holdings on-chain and builds your streak and lineage graph locally.

$ predrop wallets add 0x7f…1e
$ predrop wallets add 0x9b…a1
$ predrop scan
step 3 / act

Read the verdict, act

Decay alert? Top up. Sybil flag? Restructure. Deadline? Claim today. Score and streaks, every morning.

$ predrop serve  # localhost:4179
$ predrop sybil audit
$ predrop brief --share
// straight talk

What Predrop can't promise

You're trusting this with your positioning. Here's exactly where the edges are.

// pricing

Cheaper than the claim-checkers. Works earlier.

The post-snapshot tools' public pricing runs $21–39/mo, and they tell you about decisions already locked in. Predrop is self-hosted at every tier — paid plans are license keys with a 7-day offline grace period.

FAQ

Do I need to connect a wallet or share my keys?
Never. Predrop takes public addresses as plain text and makes read-only RPC calls (balanceOf, transaction history). There is no wallet-connect flow, no signing, no seed-phrase entry anywhere in the product. It is structurally incapable of moving your funds.
Where does my wallet list live? Isn't a list of all my farming wallets sensitive?
Extremely sensitive — which is exactly why Predrop is self-hosted. Your wallet list, lineage graph, and audit results live in local files on your machine (JSON-lines by default; SQLite if you install better-sqlite3). Predrop cloud never sees your addresses; outbound calls are limited to license checks and the RPC/webhook endpoints you configure. The cloud alternatives ask you to hand a third party the exact clustering map a sybil hunter would dream of.
How does the sybil self-audit work, and does running it expose me?
It runs locally against public on-chain data: it builds a funding graph of your wallets (who funded whom, shared CEX withdrawal addresses, common gas sources) and checks timing correlation across them — the same heuristic families used in public sybil reports like LayerZero's and Linea's. Running it creates no on-chain transactions and no external record. It estimates flag risk from known heuristics; no tool can guarantee what a specific project's filters will decide.
What's the Footprint Score, exactly?
A 0–100 number computed locally from four things: streak consistency (40%), position coverage against the protocol registry (25%), sybil risk inverted (25%), and deadline hygiene (10%). It exists so you have one number to check each morning instead of forty tabs — and when it moves, the dashboard names the reason and the fix. Share it (addresses masked) with predrop brief --share.
What chains are supported?
EVM chains via standard JSON-RPC (Ethereum, L2s, EVM sidechains — bring any RPC endpoint), plus Solana. Holdings verification works on any EVM chain where the receipt token has a standard ERC-20 interface. If you can give us an RPC URL and a token address, it generally works today.
What's the license?
Source-available: you can read and audit every line that touches your data — important for a tool you point at your whole wallet operation. Paid tiers unlock features by license key (validated online, 7-day offline grace period). Cancel anytime; your local data is yours and stays readable — plain local files, JSON-lines by default, SQLite optional.
How is this different from Drops, Earndrop, or Earnifi?
Those are claim-checkers: after a snapshot, they tell you whether an address can collect something. Useful — but by then every positioning decision has already been made. Predrop is the other side of the timeline: verifying holdings, protecting streaks, de-risking sybil exposure, and pricing your farms while the outcome is still changeable. Also: they're cloud services holding your address list. Predrop is local.
