Question 1

Is WENSER safe to use?

Accepted Answer

Yes. WENSER only reads publicly available on-chain data from block explorers to check wallet activity and airdrop eligibility. We never request, store, or have access to your private keys or seed phrase.

Question 2

Does WENSER ever ask for my seed phrase or private key?

Accepted Answer

Never. No legitimate crypto tool will ever ask for your seed phrase or private key, and WENSER is no exception. If anything claiming to be WENSER asks for this, it is a scam.

Question 3

Do I need to connect my wallet, or can I just paste an address?

Accepted Answer

You can check any wallet by simply pasting its public address - no connection required. Connecting your wallet is optional and only used for a more personalized dashboard experience.

Question 4

What permissions does connecting my wallet give WENSER?

Accepted Answer

Connecting your wallet only grants read access to view public balances and transaction history. WENSER cannot move funds, sign transactions, or approve token spending on your behalf.

Question 5

What is WENSER and how does it check for airdrops?

Accepted Answer

WENSER is a crypto wallet dashboard and on-chain activity checker. It scans a wallet's history across supported chains and breaks down the activity - balance, transaction volume, wallet consistency, contract and dApp interactions, deployed contracts, and token usage. These are the kinds of metrics airdrops commonly weigh, so you can gauge and improve your wallet's standing.

Question 6

Does connecting a wallet change what WENSER shows?

Accepted Answer

No. WENSER runs entirely on the public address you check, whether you paste it or connect a wallet. Connecting only makes it more convenient to load your own address; the on-chain data and calculations are exactly the same either way.

Question 7

How recent is the data, and does WENSER cache results?

Accepted Answer

Every check reads your activity live from the chain and its block explorer at the moment you run it, so the numbers reflect your latest on-chain state. Your balance in particular is fetched in real time directly from the network.

Question 8

How far back does WENSER scan my history?

Accepted Answer

WENSER reads your transaction history in pages, going back through your activity up to a fixed internal page limit. For the vast majority of wallets this covers your entire history. Wallets with an exceptionally large number of transactions may be read only up to that limit rather than in full, so the very oldest activity on those wallets may not be included.

Question 9

Why does WENSER only count outgoing transactions for activity metrics?

Accepted Answer

Metrics like wallet age, unique days/weeks/months, volume, and contract interactions are based on transactions you sent, not ones you received. This is intentional: outgoing transactions reflect real activity you initiated, so receiving airdrops, dust, or spam tokens can't inflate your numbers.

Question 10

Why might my numbers differ from the block explorer?

Accepted Answer

A few reasons: WENSER counts only successful transactions, excludes self-transfers (where you send to your own address), and focuses on outgoing activity for most metrics. It also reads your history in pages up to a fixed limit, so extremely large histories may not be read in full. The result is a cleaner view of meaningful activity rather than a raw transaction dump.

Question 11

How is wallet balance calculated?

Accepted Answer

Wallet balance is your current native token balance, read directly from the chain in real time. WENSER shows both the token amount and its USD value, which is the balance multiplied by the current market price of the native token.

Question 12

How are sent and received transactions counted?

Accepted Answer

WENSER pulls your full transaction history from the chain explorer and splits it into sent and received. A transaction counts as "sent" when it originates from your address and "received" when it arrives at your address. Transactions where you send to your own address (self-transfers) are excluded from both counts, so they never inflate your totals. WENSER also tracks your total transaction count and the timestamps of your first and last activity.

Question 13

How is wallet age calculated?

Accepted Answer

Wallet age is the number of days between your very first outgoing transaction on that chain and today. WENSER finds the earliest transaction you sent, then counts the full days elapsed since then. A wallet with no outgoing activity on the chain shows an age of 0.

Question 14

How are unique days, weeks, and months calculated?

Accepted Answer

WENSER groups your outgoing transactions by calendar day, ISO week, and calendar month, then counts how many of those periods show consistent activity. A day counts as "unique" when it has at least 2 transactions, a week when it has at least 4, and a month when it has at least 7. This rewards steady, ongoing usage rather than a single burst of transactions.

Question 15

How is volume calculated, and how are token values determined?

Accepted Answer

Volume is the total value you moved in your outgoing transactions, expressed in the chain's native token and its USD equivalent. WENSER adds up the native token amounts you sent, plus any token transfers in the same transactions. Stablecoins are counted at their face value in USD, while all other tokens are valued using their current market price. Everything is then combined into a single native-token and USD total. Only successful transactions are counted.

Question 16

How are contract and dApp interactions calculated?

Accepted Answer

A contract interaction is any successful outgoing transaction that carries call data (not a plain transfer), meaning you actually interacted with a smart contract. WENSER counts your total number of these interactions and, separately, the number of distinct contract addresses you touched. For dApps, each recognized protocol counts once, no matter how many of its contracts you use or how many times you use them.

Question 17

How does WENSER detect contracts I've deployed?

Accepted Answer

When you deploy a smart contract, the transaction carries a specific type of contract-creation data. WENSER scans your successful outgoing transactions for that signature to identify which ones deployed a contract, giving you a count of the contracts you've launched.

Question 18

How is token usage calculated?

Accepted Answer

WENSER looks at the token transfers you initiated and groups them by token. For each token it tracks how many times you used it and the total amount transferred. Tokens that WENSER recognizes for that chain are shown with their name and logo, and any unrecognized tokens you've used are still listed so you get the full picture.

Question 19

How is dApp usage calculated?

Accepted Answer

WENSER maintains a list of known dApps and their smart-contract addresses for each chain. It matches your outgoing transactions against those addresses to determine which dApps you've used, how many times you've interacted with each, the volume you moved through them, and when you first and last used them.

Question 20

Does WENSER guarantee I'll receive an airdrop?

Accepted Answer

No. WENSER breaks down your on-chain activity - the kind of metrics airdrops commonly weigh - but it cannot guarantee any airdrop. Projects set and change their own eligibility rules and can decide to exclude wallets at any time. Treat WENSER as a guide to understand and improve your positioning, not a promise of rewards.

Question 21

Which chains and networks does WENSER support?

Accepted Answer

WENSER supports a growing set of EVM chains, with new ones added regularly. The checkers we currently support are: Ethereum, Base, Arc, Ink, Robinhood, Linea, Optimism, Arbitrum, Monad, Polygon, Berachain, Scroll, Blast, Mode, Taiko, HyperEVM, Unichain, MegaETH, Soneium, Jumper, Relay, Swapscout, Zapper, Gas.zip, Across, Mayan, Polymarket. The full, up-to-date list is always shown in the checker selector on the dashboard.

Question 22

What can I check with WENSER?

Accepted Answer

Each supported chain has its own checker. Pick a checker, paste an address, and WENSER pulls that wallet's full activity for the chain - balance, sent and received transactions, wallet age, unique days/weeks/months, volume, contract and dApp interactions, deployed contracts, and token usage. You can search and filter checkers by name in the selector on the dashboard.

Question 23

Why is a checker marked "New", "Disabled", or "Under Maintenance"?

Accepted Answer

Checkers are tagged so you always know their status. "New" marks a recently added chain, while "Disabled" and "Under Maintenance" mean a checker is temporarily unavailable - usually because of an explorer or RPC issue on that chain. Disabled and maintenance checkers can't be selected until they're back online.

Question 24

What is the Lifetime Access NFT?

Accepted Answer

The Lifetime Access NFT is a one-time mint that unlocks full data on every WENSER checker, forever. There is no subscription and no renewal - mint it once and the wallet holding it keeps full access for life.

Question 25

What do I get for free, and what does Lifetime Access unlock?

Accepted Answer

The free tier includes core wallet stats, a contract and bridge summary, and airdrop simulations. Lifetime Access additionally unlocks your full transaction history, activity over time, a protocol-by-protocol breakdown, detailed token usage, and every checker - now and in the future.

Question 26

How much does Lifetime Access cost, and is it a subscription?

Accepted Answer

It is a one-time payment, not a subscription - there are no recurring charges or renewals. The exact mint price is read live from the contract on the chain you choose and shown on the mint button at checkout, so you always see the current price before confirming.

Question 27

Which chains can I mint Lifetime Access on?

Accepted Answer

You can mint on any supported chain, including Ethereum, Base, BNB Chain, Polygon, Optimism, Arbitrum, Linea, Monad. Access is tied to the wallet that holds the NFT, so a single mint on any one of these chains unlocks everything.

Question 28

Is Lifetime Access tied to my wallet?

Accepted Answer

Yes. Access is granted to the wallet that holds the Lifetime Access NFT. WENSER checks that wallet's balance of the NFT across supported chains, so as long as the NFT is in your wallet, full access stays active.

Question 29

What is the WENSER contract deployer?

Accepted Answer

The deployer lets you launch a smart contract in a few clicks, with no code. Pick a contract type, pick a chain, fill in a few details, and deploy straight from your connected wallet.

Question 30

Which contract types can I deploy?

Accepted Answer

You can deploy an ERC-20 token (fungible tokens), an ERC-721 NFT collection, or a simple storage contract. For tokens you set the name, symbol, and supply; for NFTs you set the name and symbol.

Question 31

Which chains can I deploy on?

Accepted Answer

Deployment is available on a growing set of chains, including Base, Linea, Optimism, Monad, Berachain, Scroll, Taiko, Unichain, Soneium, Arc.

Question 32

How much does deploying cost?

Accepted Answer

You pay the network gas fee plus a small deployment fee that is read live from the contract before you deploy. Because the fee is charged in the chain's native token and depends on network conditions, the exact amount is determined at deploy time.

Question 33

Are the deployed contracts safe?

Accepted Answer

The deployer uses standard, battle-tested contract templates (ERC-20, ERC-721, and simple storage) deployed through an on-chain factory. You always deploy from your own wallet and sign the transaction yourself, so you stay in full control.

Question 34

What is the WENSER faucet and how does it work?

Accepted Answer

The faucet gives you testnet ETH instantly by swapping a small amount of real ETH for it - no rate limits, no sign-ups, and no empty faucets. You send a small amount on the source network and receive testnet funds on the destination network.

Question 35

Which testnets does the faucet support?

Accepted Answer

The faucet supports testnets such as Arc, with more added over time. The available source and destination networks are shown directly in the faucet widget.

Question 36

Are there any rate limits or sign-ups?

Accepted Answer

No. Unlike traditional faucets, there are no rate limits, no captchas, and no accounts. The amount you can receive depends only on how much testnet ETH the faucet currently holds, which is shown before you confirm.

Question 37

Is WENSER free to use?

Accepted Answer

Yes. Checking wallet addresses and airdrop eligibility on WENSER is free. Lifetime Access is an optional one-time upgrade that unlocks the full data on every checker.

Question 38

Do I need to create an account?

Accepted Answer

No account is required to check airdrop eligibility. You can search any wallet address directly.

Question 39

Can I check a wallet that isn't mine?

Accepted Answer

Yes. Since WENSER only uses public on-chain data, you can check the eligibility of any public wallet address, including ones you don't own.

Question 40

How is WENSER different from other airdrop checkers?

Accepted Answer

WENSER combines airdrop eligibility checking with a full wallet dashboard, a no-code contract deployer, and an instant testnet faucet in one place - so you can track your activity and opportunities without juggling multiple tools.

Question 41

Where does your data come from?

Accepted Answer

WENSER reads data directly from each chain's block explorer and RPC, so the information you see always reflects the most up-to-date on-chain activity for your wallet.
