zkSync Airdrop
A plain-language, security-first guide to zkSync Airdrop: what it is, how rewards are calculated,
how eligibility usually works (snapshots + scoring + anti-sybil), and exactly how to check and claim,
then prove the result on-chain using the explorer.
Quick rule: eligibility is address-based. Always verify outcomes with explorer proof (tx hash → status → token transfer → contract).
A zkSync airdrop is a token distribution connected to the zkSync ecosystem. Wallets can receive tokens for prior activity
(using apps, bridging, swapping, providing liquidity, participating in campaigns) before a defined time checkpoint called a snapshot.
Most confusion comes from one thing: airdrops are address-based. There is no username. If you used multiple wallets, each wallet can have a different result.
What an airdrop is (operationally)
Eligibility computed from wallet activity
Allocation is assigned to eligible addresses
Tokens are claimed (or auto-distributed)
Explorer shows proof of transfer/mint
What it is NOT
Not “guaranteed” for everyone who used zkSync once
Not a reason to share seed phrases (never)
Not something you can “fix” with random tools
For beginners: use an explorer as your truth source. If a UI says “claimed” but explorer shows no token transfer, treat it as “not claimed yet.”
zkSync Airdrop Rewards: How Distributions Usually Work
Rewards can arrive in different formats depending on how the distribution is designed. This section helps you understand what you’re receiving and how to verify it.
Reward format
What you receive
How it shows up
Claimable tokens
A fixed token amount assigned to your address
Claim tx → explorer shows token transfer/mint
Auto-distributed tokens
Tokens sent to your wallet automatically
Explorer shows incoming transfer (no claim UI)
Points → tokens
Points or campaign score converted into allocation
Allocation appears when distribution is published
Partner/ecosystem rewards
Tokens from projects in the ecosystem
Separate claim pages and separate contracts
Reality check: high “estimated value” screenshots are not proof. Only an on-chain transfer from an official token contract is proof.
Eligibility Explained: Snapshots, Scoring, and Anti-Sybil (Plain Language)
Eligibility is typically computed using a combination of timing + activity + quality filters. While exact rules differ by distribution, the logic usually includes:
Component
What it means
Why it exists
Snapshot
A cutoff time when your past activity is measured
Stops “last-minute farming” after announcement
Activity scoring
Actions can be weighted (not all tx are equal)
Rewards meaningful usage vs spam transactions
Anti-sybil filters
Heuristics to detect many wallets controlled by one actor
Reduces fake farming and improves fairness
Exclusions
Some behaviors can be excluded/penalized
Discourages manipulative patterns
Common “I’m confused” scenarios
Used zkSync but actions were after snapshot
Used a different wallet than the one connected
Wallet flagged by anti-sybil filters
Allocation exists but wallet UI doesn’t show token
What you should do first
Confirm your address (copy/paste exact)
Use the official checker (if provided)
Use explorer to verify claim/transfer
Ignore unofficial “fixers” and “boosters”
Key idea: anti-sybil filters are why “same actions” can lead to different outcomes. It’s not always a bug.
How to Check zkSync Airdrop Eligibility (Step-by-Step)
Open an official zkSync link (official website/docs/portal).
Navigate to the eligibility/claim page linked from official sources.
Connect your wallet and confirm you selected the correct account.
Read the eligibility result: eligible/not eligible/needs action.
Save proof: take note of allocation, eligibility page state, and any official claim contract reference.
Beginner tip: if you used multiple wallets, check each one separately. Eligibility is not “profile-based.”
How to Claim zkSync Airdrop (Step-by-Step How To)
A safe claim is a predictable workflow. Don’t rush. Most problems are preventable with 2 checks: the contract you interact with + the token contract you receive.
Prepare gas: keep enough ETH for fees on the chain where the claim happens.
Open the official claim page and connect your wallet.
Click “Claim” and carefully read the wallet prompt.
Confirm the transaction and copy the tx hash.
Verify on explorer: status success + token transfer event.
Verify token contract: open the token contract page and confirm it’s the official one.
Post-claim hygiene: review allowances and revoke what you don’t need.
What a normal claim looks like
Single claim transaction
Status becomes success on explorer
Token transfer/mint appears in events
Balance updates after adding correct token
What to avoid (safe claiming)
Seed phrase requests (never)
Unexpected approvals for unrelated tokens
Signing unknown “permit” messages without understanding
Transactions sending your assets away
If you’re unsure: cancel the signature and verify the contract address on the explorer first.
Deadlines, Snapshots, and Claim Windows (No Confusion)
These three timestamps matter in almost every airdrop:
Snapshot: the cutoff for eligibility calculation.
Announcement: when rules and allocations are published.
Claim window: the period when claiming is allowed.
If you miss the claim window, you may permanently lose the allocation. Always rely on official announcements for deadlines.
Operational rule: don’t claim “in a panic.” Claims remain available until the official window ends.
Wallet Setup (zkSync Era): RPC, Chain ID, Explorer
If the claim happens on zkSync Era, your wallet must have correct network settings. These values are commonly used in official zkSync resources.

Proof of tx + contract addresses
Tip: if a page asks to add a “new network” you’ve never heard of, stop and verify the domain + official docs first.
Explorer Proof: How to Verify You Received zkSync Airdrop Tokens
Explorer proof is the fastest way to confirm your claim. Use this checklist:
Open your address on zkSync explorer.
Find the claim transaction by time or tx hash.
Confirm Status: Success.
Open the event log / token transfers and identify the token contract.
Open the token contract page and confirm it is official.
Confirm your token balance (holders/balance view or token tab).
Review and revoke token approvals after claiming.
Open Revoke.cash
Most common issue: explorer shows the token transfer, but the wallet doesn’t show the token. Fix = add token using the explorer-verified contract address.
Best Practices: Safe Claiming Checklist (Fast + Practical)
Before you claim
Use a clean browser profile (wallet-only extensions)
Confirm domain from official zkSync sources
Keep ETH for gas (don’t go “all-in”)
Prefer hardware wallet for claims
Domain verifyGas bufferHardware wallet
After you claim
Verify tx + token transfer on explorer
Add token only via explorer-verified contract
Revoke unnecessary allowances
Save tx hash for your records
Explorer proofContract verifyRevoke
Beginner shortcut: if you do just (1) official link, (2) explorer proof, (3) revoke approvals — you’re already ahead of most people.
Troubleshooting: Common Problems and Fixes
“Not eligible”
Confirm you used the correct wallet address (and correct account in the wallet).
Check if the snapshot was before your activity.
Some wallets are filtered by anti-sybil rules; official sources are the only authority.
“Claim transaction failed / reverted”
Insufficient gas or temporary network congestion.
Try again once after verifying official claim page and having enough ETH.
If failures persist, check official status updates and wait.
“Claim succeeded but tokens not showing”
Use explorer to confirm token transfer and contract address.
Add the token manually using the explorer-verified contract.
Refresh the wallet, restart browser, or switch RPC (reputable only).
“Wrong wallet / wrong network”
Switch the wallet network to zkSync Era (if claim occurs on Era).
Verify the address on explorer; the chain context matters.
Golden rule: if explorer shows success + token transfer to your address, your tokens are almost never “gone.”

zkSync Airdrop FAQ
A token distribution connected to the zkSync ecosystem. Eligibility is usually calculated from past wallet activity before a snapshot time.
Start from official zkSync links, open the official checker (if provided), connect the correct wallet address, and read the eligibility result. Verify any claim result on explorer.
Open the official claim page, connect wallet, submit the claim transaction, copy the tx hash, then confirm success and token transfer on zkSync explorer.
Common reasons: activity happened after snapshot, activity was minimal, wallet behavior triggered anti-sybil filters, or you checked a different wallet address than the one you used.
Use explorer proof: confirm token transfer and the token contract address. Add the token manually using the explorer-verified contract. Wallet UIs often lag.
The commonly used zkSync Era Mainnet chain ID is 324. Verify using official zkSync documentation if you are unsure.
