BNB Chain airdrops without the guesswork

Three chains under one name

The BNB Chain docs describe a family of three chains. Which one a campaign uses changes what you sign and what you pay, so ask first.

The docs add that BNB is the native token and, along with fuelling transactions, acts as a governance token. They describe the network as secured by more than 20M BNB staking and 20K delegators; we quote that as the docs' own claim. For comparison with other EVM environments see Ethereum and Base.

EVM rules apply, including the bad ones

Because BSC is EVM-compatible, the account model is the one you know. An address works across EVM networks, and approvals persist until revoked. That makes the revoke routine in our approvals guide as relevant here as anywhere. It also means the one address you use on BNB Chain is the same one you may use elsewhere, so a leak in one place is a leak in all of them. Use a separate wallet for campaigns, set up with the burner wallet guide.

One difference is chain-specific: network selection. Your wallet may show several networks with the same address. Sending a token on the wrong network is a common and often unrecoverable error, and a campaign page that tells you to "switch network" is asking you to take the step where mistakes happen. Check the network name and chain ID in your wallet before confirming anything.

Case study: Aster, a BEP-20 token and a cautious claim

Aster is a perpetual futures exchange with its own chain, and its ASTER token launched on 17 September 2025 as a BEP-20 token on BNB Chain with a maximum supply of 8 billion. Our Aster airdrop page has the complete record. The first airdrop, 704 million ASTER unlocked at launch, could be claimed from 17 September to 17 October 2025, and unclaimed tokens were redirected to the community rewards allocation.

Three routes qualified for the first airdrop: points in the Aster Spectra Stage 0 and 1 programmes above a minimum, an Aster Gems allocation from a community or partner initiative, or loyalty rewards from trading on Aster Pro after Stage 1. Later points pages, Stage 5 and Stage 6, remain in the docs. The Stage 6 page says points accumulate toward an ASTER airdrop share, but gives no end date, snapshot or token amount. Treat that as unconfirmed. The scoring itself rewards trading volume, position size and time, and the docs say weightings are undisclosed and farmed points may be adjusted. Perpetual trading involves leverage and liquidation risk, so chasing points with volume you would not otherwise trade can cost more than the points are worth.

Cost of participation

The docs name BNB as the fee token and cite a network-wide standard gas price of 0.05 gwei. They do not give a dollar figure, and we will not invent one. Here is how to think about total cost.

The biggest cost in most campaigns is not gas. It is capital at risk in an application. See airdrop farming for how we weigh that.

Wallets, RPC and explorers named by the docs

• Wallets. The BSC quick guide lists Binance Web3 Wallet, MetaMask, TrustWallet, OKX Wallet and Gem Wallet as compatible. A listing is a compatibility statement, not a security review.
• RPC. The JSON-RPC page gives mainnet chain ID 56 (0x38) and endpoints including https://bsc-dataseed.bnbchain.org and https://bsc-dataseed-public.bnbchain.org on the first-party domain. The public endpoints have a rate limit of 10K requests per 5 minutes, and eth_getLogs is disabled on them.
• Explorers. BscScan and NodeReal BSC Scan are listed on the quick guide.
• Bridges. The pages we opened have a cross-chain bridge section in navigation but no URL, so we name none. Find a bridge in the docs of the application that needs it.

Open these from the BNB Chain docs, not from an ad or a message. For the principles of holding keys yourself, see custodial versus non-custodial.

Scam patterns we would expect on BNB Chain

The docs do not catalogue scams, so this is editorial analysis built from the network's design and from the Aster documentation's own warnings.

• Approval phishing. The first thing a fake claim does is ask you to approve a token. Aster's docs say the real flow needs none.
• Fake tokens with a real-sounding name. Low fees make creating tokens cheap. Verify the contract address from the project's docs and the explorer before interacting.
• Wrong-network instructions. A page tells you to send funds on a specific network to a "verification" address. Real claims do not ask for deposits.
• Public RPC swaps. A guide telling you to add a custom RPC from an unfamiliar domain. Use the endpoints on bnbchain.org.
• Points-stage hype. Pages that describe an undisclosed payout as confirmed. Check the actual docs page for an end date or amount.

Our stance on exchange-linked and points campaigns

BNB Chain is a place where exchange products, wallets and DeFi sit close together. We only describe a campaign when its own documentation lets us verify the rules, and we do not rank projects by who is behind them. Points programmes and trading competitions are common here, and our points guide explains why points are not a contract. Where the docs do not state a payout, we say so, as with Aster's later stages.

When a BNB Chain campaign does appear, read it in this order. First, is the reward described as a token, as points or as nothing specific? Aster's Stage 6 page, for instance, describes how points accumulate but not what a point is worth. Second, who holds your assets while you earn: in Aster's claim flow the tokens were credited to a platform spot account rather than sent to your own wallet, which is a custody difference worth noticing (see our custody guide). Third, what is the stated end: a snapshot date, a stage end or a claim deadline. A programme with no stated end is an invitation to keep spending.

Finally, remember that receiving a token can have tax consequences that depend on where you live. We do not give tax advice, but our airdrop tax guide explains the questions to ask an adviser.
