Summary

Fantom and the original Fantom project existed before Andre Cronje joined.

A contemporaneous Fantom publication identified Andre as a Technical Advisor in 2018. He later co-authored Fantom and Lachesis technical research, helped establish technical teams, became a director, and in August 2024 became Chief Technology Officer of Sonic Labs with responsibility for leading development of the Sonic network, especially Sonic Gateway.

Sonic Labs has publicly stated that Andre did not design the original 2018 Fantom tokenomics. Andre states that he did not design, author, sponsor, advise on, or participate in the FTM-to-S launch tokenomics or the later 2025 issuance and fee-and-burn governance proposal. That proposal quoted an earlier public statement by Andre and referred separately to DeFi activity he had led. A quotation or reference to unrelated activity is not evidence of authorship, participation, or decision ownership.

Andre resigned from the Sonic Labs board in June 2026 and no longer makes business decisions for the organization.

Verified public record

Initial role and technical authorship

The earliest official Fantom source reviewed for this page identified Andre as a Technical Advisor in 2018.

Public academic records identify Andre as a co-author of early Fantom and later Lachesis research with other contributors.

Fantom stated in 2022 that Andre helped establish the existing development team while emphasizing that he was not the sole or core developer of the complete Fantom technology stack.

The accurate description is:

Andre Cronje did not form the original Fantom company or token project. His technical contribution was foundational, and the working network was implemented by a wider team.

The 2022 departure and project continuity

On March 11, 2022, Fantom Foundation stated that Andre Cronje and Anton Nell had not terminated 25 projects and that involvement such as interfaces would be handed over to existing teams. Contributor departure, interface handover and protocol operation are distinct events.

Sources: Fantom Foundation's March 11 statement, items 3 and 6.

Scope. This is the Foundation's contemporary clarification, not a guarantee about every project's later survival, interface availability or user funds. The same statement credits independent project teams and the wider Fantom development team.

What the dated clarification establishes

  1. March 2022 — Departure announcement. The Foundation's subsequent statement addressed descriptions of 25 projects being terminated alongside Cronje and Nell's departure.

  2. . It distinguished contributor involvement from the projects themselves and described handover to teams already operating independently, including Yearn and Multichain.

Continued contract execution, maintained interfaces, governance and withdrawal access require separate evidence for each project and period. See the Yearn governance and continuity record and ve33 maintainer record for project-specific context.

Last checked . Added the dated clarification and continuity limits.

Bridge transfers were not a personal-profit calculation

In March 2022, Rekt withdrew a Fantom article after challenges to its wallet analysis. NewsBTC recorded Multichain's then-CEO explaining that questioned transfers replenished native-FTM bridge liquidity through Binance. Exchange transfers alone do not establish executed sales or personal profit. The reporting did not reconcile every transfer.

Sources: NewsBTC's March 11 account · Blockbytes' reproduced apology and withdrawal history.

Scope. These are contemporary reports of the explanation and withdrawal. NewsBTC discussed approximately US$750 million in gross FTM transfers, not a verified personal-profit total, and noted that some amounts remained unmatched. The original Rekt body and original social posts were not directly retrieved for this review.

Publication, withdrawal and source access

  1. Original article — The Fantom Menace. Contemporary coverage identifies Rekt's withdrawn article and its wallet-transfer interpretation. A March 10, 2022 archive link is available as a research lead; the archived body was not retrieved and is not treated as reviewed evidence here.

  2. . Blockbytes reproduces Rekt's dated apology and reports the article's withdrawal. This is a reproduction, not direct retrieval of the original social post.

  3. . NewsBTC attributes the bridge-liquidity explanation to Multichain's then-CEO and records the unresolved reconciliation gap.

  4. . Blockbytes recounts the withdrawal and reproduces the earlier apology. It is another account of the same event, not a separate transaction audit.

Gross transfer volume, executed sales and personal proceeds are different measures. The explanation does not classify every asset in the related wallets as bridge property or resolve all questions about their administration. A complete accounting would match the relevant deposits, withdrawals and bridge destinations and show unmatched amounts separately.

Last checked . Added attributed withdrawal history, bridge context and source-access limits.

Director and Chief Technology Officer

By August 2024, Andre was a Sonic Labs director and became Chief Technology Officer.

Sonic's official announcement stated that Andre's mandate included leading the design and development of the Sonic network, particularly Sonic Gateway.

Sonic Labs board statement

In February 2026, Sonic Labs published a board statement titled Setting the Record Straight concerning public commentary about Andre Cronje and the Sonic network.

The statement says that the original South Korean Fantom team launched the ICO, mismanaged proceeds, and failed to deliver a functional product. Sonic states that Andre became involved from June 2018 onward and that his work helped restructure, stabilize, and revive the project.

Sonic also states that the Seoul High Court judgment concluded that the current technical team led by Andre Cronje developed a working product that the South Korean team failed to deliver.

The same statement says that Andre was not responsible for designing the original Fantom tokenomics and did not abandon Fantom/Sonic.

This is an official Sonic Labs statement and should be cited as Sonic Labs' position.

Tokenomics

Andre states that he did not design or serve as decision owner for:

Sonic Labs' statement supports the original Fantom-tokenomics point. The broader statements about migration, airdrop and later proposals are Andre's account of his role; the reviewed public sources do not independently allocate every decision.

The 2025 governance proposal included a quotation attributed to Andre and referred to separate strategic DeFi activity. Andre states that he did not author, sponsor, draft, advise on, or participate in that proposal. The proposal should not be cited as evidence that Andre was involved in its tokenomics.

Migration and airdrop decision ownership

The public sources reviewed for this page do not independently establish who designed, approved, or operationally executed every element of:

Andre's personal statement addresses his role. A stronger public record should add an organization-confirmed responsibility matrix or governance and implementation records.

Board resignation and handover

On June 19, 2026, Sonic Labs announced that Andre, Michael Kong, and David Richardson were resigning from the board.

The announcement states that responsibilities were being handed off in full and that Andre would no longer make business decisions for the organization. Matt Visser became Chief Executive Officer and Kosta Kourkoumelis became Chief Operating Officer.

Responsibility accepted

What the public record does not establish

The sources reviewed for this page do not establish:

The public proposal text contains an attributed quotation and a reference to separate DeFi activity. Those facts do not establish authorship, drafting, sponsorship, advice, approval, or participation in the proposal.
