How to spot a bundled launch

What a bundled launch is

A launch is bundled when one person or group buys a new coin through many coordinated wallets in its first seconds, often with wallets funded from the same place. The coin can look widely held while a few people control much of its supply and can sell it at once.

Send.Do does not currently detect or block bundled launches, and its public bundler list is not live. The checks below use public Solana data and a block explorer such as Solscan. You can run them on any coin, on any site.

Five checks you can run

1. Measure holder concentration against total supply. Open the coin's holder list. Add up what the 10 largest holders own, leaving out the bonding curve or liquidity pool account, which holds coins for trading rather than for a person. Then divide by the coin's total supply, not by circulating supply and not by the supply left after removing the pool. For example, if the top 10 wallets other than the pool hold 300,000,000 of 1,000,000,000 coins, they hold 30%.
2. Count wallets, not token accounts. One wallet can own several token accounts for the same coin. Explorers usually show the owner of each account; group accounts by owner before you count holders.
3. Look at the first buys. Sort the coin's transactions oldest first. Many different wallets buying in the same block as the launch, or within a few seconds of it, often in similar amounts, is a warning sign.
4. Check where early wallets got their SOL. For the largest early buyers, open each wallet's oldest transactions. Several wallets funded by the same address shortly before the launch suggests one owner.
5. Notice brand-new wallets. Large holders whose first activity was buying this coin, with no history before it, are harder to tell apart from one another and are worth a closer look.

What these checks cannot tell you

• None of them proves intent. Early buyers can be ordinary fast traders; sniping is not the same as bundling, and Send.Do does not prevent sniping either.
• A shared funding source can be innocent. Exchanges and payment services send SOL to many unrelated wallets.
• Coordinated wallets can be funded through many hops to look unrelated, so a clean result is not proof that a launch was not bundled.
• Holder lists change with every trade. A result is only true for the moment you check.

On Send.Do

Send.Do's coin pages show market context from OTC, public Solana data and market-data providers, which can be delayed or incomplete. A coin appearing on Send.Do, trending or featured is a discovery signal, not a check that it was launched fairly. See the Transparency page for what is live.
