Editing Justin Sun

**Justin Sun** is a China-born crypto entrepreneur and the founder of the Tron blockchain. In memecoins he is known for launching [[SunPump]], a Tron launchpad, in 2024 and for becoming the largest known holder of [[Official Trump|TRUMP]] in 2025.[^1][^2][^3]

## Background
Reuters describes Sun as a China-born crypto entrepreneur. He is an adviser to World Liberty Financial, the crypto venture tied to the Trump family, and its second-largest known investor.[^1] In March 2023 the US SEC charged him and three related companies, including the Tron Foundation, with unregistered sales of the TRX and BTT tokens. It also accused him of [[Wash trading|wash trading]] TRX and of paying celebrities to promote the tokens without disclosure.[^4]

## Notable trades
### SunPump
- 2024-08: Sun introduced SunPump, which billed itself as the "first meme fair launch platform" and was positioned as Tron's rival to [[Solana]]'s [[pump.fun]]. The team marketed it as having no [[Rug pull|rug pulls]] and no team allocation, and Sun set aside $10 million for an incentive program for SunPump coins.[^2]
- 2024-08-15: SUNDOG launched and became Tron's flagship memecoin. It peaked at a $325 million market cap, and Decrypt compared its rise to [[dogwifhat]]. Dune data cited by Decrypt showed more than 11,000 tokens created on SunPump within its first week.[^2]

### Comedian
- 2024-11-20: Sun bought Maurizio Cattelan's banana artwork "Comedian" for $6.24 million at Sotheby's in New York. He called it "a cultural phenomenon that bridges the worlds of art, memes and the cryptocurrency community".[^5]
- After his bid was confirmed, the largest unaffiliated Solana memecoin themed on the artwork, [[Comedian|BAN]], fell 37%. Its market cap dropped from nearly $241 million to a low of $151 million.[^5]

### TRUMP
- 2025-05: before a gala dinner hosted by President Trump for top TRUMP holders, Sun said he held more of the token than anyone else, nearly $19 million worth.[^3]
- 2025-07-07: Tron DAO said TRUMP would launch on Tron.[^3]
- 2025-07-09: Sun posted "We are committed to buying $100 million of TRUMP", with the token trading at $8.89.[^3]

### World Liberty Financial
- 2024-11: weeks after the US election, Sun bought $30 million of World Liberty Financial (WLFI) tokens. He was then named an adviser and later raised his stake to $75 million.[^3]

## Controversies
### WLFI freeze
- 2025-09-04: WLFI's "guardian address" blacklisted a wallet owned by Sun holding about 545 million tokens, according to blockchain data reported by Reuters. Before that, Sun had moved 50 million tokens to another address, per a Nansen analyst.[^1]
- Sun posted that his tokens were "unreasonably frozen" and asked for them to be unlocked. World Liberty did not name him; it said it does not seek to blacklist anyone and acts when alerted to malicious or high-risk activity.[^1]

### SEC case
- 2025-07-09: lawyers for the SEC, Sun and his companies jointly asked the court to stay the case.[^3]
- 2026-03-05: under a Final Judgment in the Southern District of New York, the SEC dismissed its claims against Sun, the Tron Foundation and the BitTorrent Foundation. Rainberry, formerly BitTorrent Inc., agreed to pay a $10 million civil penalty. The defendants neither admitted nor denied the allegations, and The Block reported that the court still had to approve the judgment.[^4]
