Wu said that on-chain detective ZachXBT stated that he is currently focused on supporting blockchain ecosystems that actively fund his work, including Solana, Ethereum, Bitcoin, and OP/Stark. For chains that do not provide funding support, such as Arbitrum, Cosmos, zkSync, Aptos, Sui, and Scroll, he will not provide assistance for free. He explained that he receives over 1,000 requests each month, and to avoid wasting resources, he chooses to invest his time and energy into ecosystems that value his work, in order to support the ongoing development of public goods.
