Bundler

Bundler

A bundler is a tool or actor that groups multiple transactions into one bundle that lands together in a block. Technically this is neutral — bundles are a normal part of Solana infrastructure.

Neutral and problematic use

• Neutral: atomic execution of multiple steps, e.g. in DeFi strategies.
• At a token launch: an actor makes many of their own wallets buy in the same block to secure a large share of the supply early — often hard to distinguish from genuine demand.

Forensic relevance

Bundled initial buys from a wallet cluster are a common signal when analyzing token launches. On-chain, it is traceable which wallets bought in the same bundle and whether they are connected.
