Corrections & Documentary Record
Approved factual wording for role history, Eminence context, and publisher correction requests.
This page provides approved factual wording for publishers, compliance teams, researchers, and data providers reviewing public information concerning Andre Cronje. It distinguishes company formation from technical creation, records the applicable Fantom and Sonic roles, and provides neutral context for recurring historical claims.
Scope and editorial standard
This record distinguishes documented factual errors from fair comment, criticism, and opinion. It does not seek removal of legitimate reporting merely because it is unfavorable. A correction is appropriate where a publication uses an inaccurate corporate title, conflates company formation with technical creation, or describes experimental deployed contracts as equivalent to a publicly announced production launch.
Claims that require additional legal, regulatory, or transactional evidence are not published here as verified facts until the relevant record has been reviewed and approved.

Fantom and Sonic role history
Fantom and the original Fantom project existed before Andre Cronje joined. He began contributing in 2018, after formation, initially as a technical advisor. He did not form Fantom or originate the original token, fundraising, or commercial project.
His role in the technology was foundational. He originated the core technical architecture and, together with Quan Nguyen, led the development team that implemented the working Fantom network.
Andre Cronje was appointed a director of Fantom on 13 December 2022, more than four years after the company was incorporated, and became Chief Technology Officer of Sonic Labs in August 2024. In that role, he led the design and development of the Sonic network, particularly Sonic Gateway. Sonic Labs announced his board resignation on 19 June 2026, after which he no longer participates in its business decisions.
Andre Cronje was not a founder of the company or the original Fantom token project. He was an originating technical architect of Fantom's working network, and later a director of Fantom and Chief Technology Officer of Sonic Labs.
He has sometimes used "co-founder" informally to describe his foundational technical role. That shorthand was imprecise because it collapsed company formation and technical creation into one term.
Andre Cronje did not found the company later known as Sonic Labs. He did lead the design and development of the Sonic network in his technical role. Publications should therefore use the applicable formal or technical title rather than Sonic founder or Sonic Labs co-founder.
Publisher replacement wording
Current/general biography correction
Andre Cronje is the founder of Flying Tulip. He previously served as a technical advisor and originating technical architect of Fantom's working network, later as a director of Fantom, and as Chief Technology Officer of Sonic Labs. Fantom and the original Fantom project existed before he joined.
Founder-title correction
Andre Cronje did not form Fantom, the original Fantom token project, or the company later known as Sonic Labs. Please replace `founder` or `co-founder` with the documented role applicable on the article's publication date. Where the article concerns the technology, the precise descriptions are `originating technical architect of Fantom's working network` and, for Sonic, `Chief Technology Officer of Sonic Labs who led the design and development of the Sonic network`.
Post-resignation current-role correction
Sonic Labs announced Andre Cronje's board resignation on 19 June 2026. He no longer participates in Sonic Labs' business decisions. His current primary focus is Flying Tulip.

Eminence: experimental contracts were not a public production launch
In late September 2020, users sent funds to smart contracts associated with an experimental project called Eminence. Media reporting at the time described approximately US$15 million being deposited and then drained through an exploit, with roughly US$8 million later returned by the attacker. Separately, Andre Cronje publicly warned that the project was not ready and advised users to avoid depositing in non-announced contracts.
Deployment of contracts to Ethereum mainnet made those contracts technically accessible. It was not equivalent to a publicly announced product launch.
Publisher replacement wording
Eminence involved experimental, non-announced smart contracts that were technically accessible after deployment to Ethereum mainnet. The contracts were exploited after users deposited funds. Deployment should not be described as equivalent to a publicly announced production launch.

Regulatory context
A publicly posted SEC Crypto Task Force staff memo cited Andre Cronje's "Why did I quit in 2022" post as an example in a broader discussion of how DeFi systems might be characterized under existing frameworks. This reference is included only as a pointer for researchers; it is not a finding about Andre Cronje or any specific project.
Publisher correction wording
General request
I am requesting correction of a factual description concerning Andre Cronje. The current wording conflates company or token-project formation with technical creation, or uses a title that was not his documented role. Please correct the headline, standfirst, article body, subject profile, metadata, structured data, translated editions, and syndicated copies where applicable. The approved role record and replacement wording are available at https://andrecronje.info/corrections/.
Fantom/Sonic request
Andre Cronje did not form Fantom, the original Fantom token project, or the company later known as Sonic Labs. Please replace `founder` or `co-founder` with the documented role applicable on the article's publication date. Where the article concerns the technology, the precise descriptions are `originating technical architect of Fantom's working network` and, for Sonic, `Chief Technology Officer of Sonic Labs who led the design and development of the Sonic network`.
Eminence request
Eminence involved experimental, non-announced smart contracts that were technically accessible after deployment to Ethereum mainnet. The contracts were exploited after users deposited funds. Deployment should not be described as equivalent to a publicly announced production launch.
