# Crypto Airdrops: Claim Deadlines and Official Contracts

> Crypto airdrops open to claim now: each claim deadline, the official claim contract checked on-chain, tokens left to claim and announced claims to come.

**Question:** Which airdrops can be claimed now, when do their claim windows close and which contract is the official one?

- Kind: Table in Voltfin Strata
- Topic: [Markets and trading](https://voltfincrypto.com/topics/trading)
- Chains: Multi-chain, Ethereum, Arbitrum, Base, Solana
- Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is.

Airdrops reward early users with tokens, and each one opens a claim window during which eligible wallets can collect. Fake claim sites appear around popular airdrops, copying their look and asking wallets to sign transactions that drain them. Knowing the official contract and the real deadline makes those fakes easier to spot.

This table lists airdrops that are open to claim or have announced claim dates. Each row names the distributor contract the project announced, checks it on-chain (its deployer, its token and the code it runs) and reads its deadline and the tokens still left in it at the latest block.

Use it to confirm a contract before interacting with any claim page. The table only reads public data; it never links to claim sites and never asks for a wallet connection.

## Blueprint

One row: One row per airdrop distributor contract

- **Airdrop** (`airdrop`): The project and the airdrop or season it distributes.
- **Token** (`token`): The token paid out, linked to its contract.
- **Chain** (`chain`): The chain the distributor contract lives on.
- **Official contract** (`distributor`): The distributor address from the project's announcement, linked to its on-chain record.
- **Status** (`status`): Open, announced or closed, from the claim window and the latest block.
- **Opens** (`claim_opens`): When claims open, from the contract where it is stored and from the announcement otherwise.
- **Deadline** (`claim_deadline`): The end time stored in the distributor, or the announced date marked as off-chain; shown as none when there is no deadline.
- **Tokens left** (`tokens_left`, tokens): The distributor's balance of the token at the latest block.
- **Claimed** (`claimed_share`): Tokens claimed as a share of the amount the distributor was funded with.
- **Checks** (`checks`): The on-chain checks passed: deployer, bytecode hash, token and funding transfer.
- **Announcement** (`source`): The project's own announcement that names the contract.

## How it will be measured

- An airdrop enters the table only when its distributor address comes from the project's own announcement, recorded with its source and date.
- Each distributor is checked on-chain: the deployer address, the hash of its runtime bytecode, the token it pays out and the transfer that funded it.
- The deadline is the end timestamp stored in the distributor where one exists; otherwise the announced date is shown and marked as off-chain.
- Tokens left and claims so far are the distributor's token balance and its Claimed events at the latest block.

## Data it needs

- `airdrop_claims` (to build): Claims from airdrop distributor contracts: eligible amount, claimed amount, claimers and what they did next.
- `address_labels` (to build): Labels for known addresses: exchanges, bridges, protocols, funds, treasuries, sanctioned addresses and known attackers.
- Source: Official claim contract addresses, tokens and claim windows from project announcements (off-chain)
- Source: Distributor contract deployer, runtime bytecode hash and token address read on-chain
- Source: Claim end timestamp, merkleRoot and remaining token balance read from each distributor at the latest block
- Source: Claimed event counts per distributor

## Questions

### How do I find the official airdrop claim contract?

Take the address from the project's own announcement channels, then check it against the chain: who deployed it, which token it holds and when it was funded. Each row of this table records those checks with its source.

### What happens if I miss an airdrop claim deadline?

Once a window closes, the distributor stops accepting claims and the project can usually withdraw the unclaimed tokens. Some distributors have no deadline. Each row shows whether the contract stores a deadline and when it is.

### How do airdrop scams work?

Most copy a real airdrop's site and ask the visitor to connect a wallet and sign a transaction or a permit that hands over token approvals. A genuine claim calls the official distributor and does not need approval to move your other tokens.

### Are all airdrops claimed on-chain?

Most are claimed through a distributor contract, but some are sent directly to wallets or credited on an exchange. The table lists on-chain claims only, since those are the ones with a contract to verify.

### Does this table say whether a wallet is eligible?

No. Eligibility is set by each project's snapshot and Merkle tree. The airdrop claim tracker can check whether a given wallet has already claimed from a tracked distributor.

## Glossary

- **Distributor contract**: The contract that holds an airdrop's tokens and releases each eligible wallet's allocation when it claims.
- **Runtime bytecode**: The code a contract runs once deployed. Its hash identifies the code, so copies and lookalikes can be compared.
- **Permit**: A signed message that grants a token approval without a transaction; phishing sites often ask for one to take a wallet's tokens.
