Summary

SubQuery Network is a Web3 data indexing protocol originally built for the Polkadot ecosystem, founded by Sam Zou and James Bayly out of New Zealand-based OnFinality. The project raised $10.8M in seed and Series A funding, launched its mainnet and SQT token in February 2024, and suffered a significant smart-contract exploit on April 12, 2026 in which a missing access-control modifier allowed an attacker to drain approximately 382 million SQT tokens (~$134,000 USD) from staker and delegator wallets across five transactions. ZachXBT flagged the entity in connection with this incident; the team published a full disclosure report and executed on-chain compensation for all affected wallets.
