Jump Crypto

Jump Crypto is the crypto arm of Jump Trading, a Chicago trading firm founded in 1999. Jump Crypto does three things. It trades crypto as a market maker. It builds open-source blockchain software. It invests in crypto projects. On Solana it is best known for Firedancer, a second version of the software that validators run to keep the network going.

Jump Crypto is a private firm that trades its own money. It has no token, and its website says it takes no funds from outside investors. The firm also has a legal past. One of its units paid $123 million to settle SEC charges over TerraUSD in December 2024, and related lawsuits were still open in October 2026.

What does Jump Crypto do? Trading, building and investing

Jump Crypto sums up its work in three words: trade, build and invest. It makes markets in crypto with its own money. It writes open-source code for blockchains. It puts money and engineers into other projects. The firm says it gives "time, capital, and code".

The three lines feed each other. Trading at high speed shows Jump Crypto where a blockchain is slow or weak. Building is how the firm tries to fix those limits, and Firedancer is the clearest case. Investing takes the same bets to outside teams.

If you use Solana, you are unlikely to deal with Jump Crypto directly. You are more likely to touch its work without seeing it: a swap that fills against its liquidity, a price feed from an oracle it helped start, or a block produced by a validator running its software.

Jump Trading vs Jump Crypto: how the two firms are related

Jump Trading is the parent firm and Jump Crypto is its crypto brand. Jump Trading is a proprietary trading firm. That means it trades its own money, in futures, stocks, options and currencies. Jump Crypto brings the same trading and coding skills to crypto and blockchains.

Jump Trading was founded in 1999 by Paul Gurinas and Bill DiSomma, two traders who met at the Chicago Mercantile Exchange, according to Wikipedia. The firm announced Jump Crypto as a separate brand in September 2021.

The line between the two is loose in practice. Court filings and press releases often name "Jump Trading" for work the crypto team does. The entity that settled with the SEC in 2024, Tai Mo Shan Limited, is a subsidiary of Jump Crypto Holdings LLC. When you read news about either name, check which legal entity is meant.

Firedancer: the Solana validator client built by Jump Crypto

Firedancer is a Solana validator client that Jump Crypto's engineers wrote from scratch in C. A validator client is the software that validators run to check transactions and agree on new blocks. Firedancer shares no code with Agave, the main client, which Anza looks after. With two clients built apart, a bug in one is less likely to stop the whole network.

Firedancer came to Solana mainnet in stages. A hybrid called Frankendancer came first. It used Firedancer's code to talk to the network and build blocks, and Agave's code for the rest. The full client was said to be live on mainnet at the Breakpoint event in Abu Dhabi in December 2025.

Two things changed in autumn 2026:

• The Firedancer team said on 11 September 2026 that it will stop supporting Frankendancer once Solana's Alpenglow consensus upgrade activates on mainnet, Crypto Briefing reported. The team cited the maintenance and security burden of the hybrid. Validators on Frankendancer need to move to full Firedancer or back to Agave.
• Alpenglow support in Firedancer is still arriving. Anza told testnet operators on 22 September 2026 that neither Firedancer nor Frankendancer supported the Alpenglow migration, as we covered in our report on the testnet activation. On 6 October 2026 a merged Firedancer change marked Alpenglow as supported, with a note that the migration step itself was not.

Our Firedancer profile covers the client's design, releases and adoption in more depth. For the engineers' own account, see our summary of Michael McGee on the state of Firedancer.

BisonFi and PropAMMs: Jump's on-chain market making on Solana

Jump runs its own PropAMM on Solana, called BisonFi. PropAMM is short for proprietary automated market maker. It is an on-chain program where one trading firm sets the prices. The firm works out its prices off-chain and keeps the program up to date. Your swap then settles on-chain against the funds held in that program.

Jump Crypto named BisonFi as its own in an April 2026 paper, "PropAMMs and the Next Chapter of Permissionless Market Structure". The paper argues that PropAMM prices on major Solana pairs matched or beat centralized exchanges. Keep in mind that this is a market maker grading its own product. We track the wider trend in our coverage of PropAMM market share.

Jump has since taken the model to tokenized stocks. On 5 May 2026, Securitize, Jump Trading Group and Jupiter JUP$0.315-1.3% announced regulated on-chain trading for tokenized equities on Solana, with Jump supplying liquidity through its PropAMM. On 8 October 2026, Securitize named Jump Trading as a market maker for Securitize Stocks.

If you swap through an aggregator, you may trade against Jump without knowing it. The aggregator picks the best quote, and some of those quotes come from PropAMMs.

Pyth, Wormhole, DoubleZero and Shelby: projects Jump Crypto helped build

Jump Crypto has helped start or fund several other projects besides Firedancer. Most now have their own team or foundation. Jump Crypto's role in each differs, so check what it does today before you assume it is in charge.

• Pyth Network PYTH$0.094+7.1% is a price oracle, a service that puts market prices on-chain for apps to use. Pyth was incubated at Jump Trading and went live on Solana in August 2021. In August 2023, former Jump staff left to found Douro Labs, which now works on Pyth, Bloomberg reported.
• Wormhole W$0.015-4.6% is a bridge that moves assets between blockchains. After an attacker minted 120,000 wrapped ETH in February 2022, Jump Crypto replaced the 120,000 ETH, worth more than $320 million at the time.
• DoubleZero 2Z$0.033-0.4% is a private fibre network for validators. Jump Crypto is a core contributor and supplied early bandwidth, CoinDesk reported in March 2025. DoubleZero was founded by Austin Federa, Andrew McConnell and Mateo Ward.
• Shelby is a decentralized storage network that Jump Crypto is building with Aptos Labs. Shelby is coordinated on the Aptos blockchain, so it sits outside Solana.

Jump Crypto also puts out research. In April 2026 it posted a paper on how Solana could move to quantum-safe keys. In July 2026, David Rubin and Emanuele Cesena of Jump Crypto wrote a paper on checking Falcon signatures faster. Falcon is a way to sign data that is built to hold up against quantum computers.

Jump Crypto investments and portfolio

Jump Crypto invests its own money in crypto firms and protocols. Its website has no portfolio page, so the public record comes from deal news.

Two deals show the pattern. Jump Crypto took an equity stake in Securitize in May 2025. A year later the two firms launched tokenized stock trading together. On 6 October 2026, Navra closed a $19 million Series A led by Ribbit Capital. Navra is an AI trading platform founded by Mike Cagney. Jump Crypto was named as a strategic investor, according to Crypto Briefing.

Investor databases often mix up Jump Crypto, Jump Trading and Jump Capital. Treat their portfolio lists as a starting point. Check each deal against the company's own news.

Is there a Jump Crypto coin, and who is Jump Crypto relevant to?

There is no Jump Crypto coin that we could find, and you cannot invest in Jump Crypto. The firm is privately held and trades only its own capital. Its website warns that anyone claiming to accept investor funds on behalf of Jump Crypto is fraudulent. A token called JUMP, announced for sale in September 2026, belongs to Jumper, an unrelated bridging app.

Jump Crypto matters most to three groups:

• Validator operators deciding whether to run Firedancer or Agave. Operators on Frankendancer face a deadline: the hybrid loses support when Alpenglow activates on mainnet.
• Traders and DeFi teams who want to know who is on the other side of a swap, since Jump's BisonFi PropAMM quotes prices on Solana.
• Founders and researchers who work near market structure, validator software or cryptography, where Jump Crypto invests and publishes.

If you hold SOL and want to know how resilient the network is, Jump Crypto is relevant for one reason. Its engineers maintain one of the two independent validator clients.

Jump Crypto lawsuits, the SEC settlement and other risks

Jump Crypto's biggest risk is legal, and it traces back to the collapse of TerraUSD in 2022. One case is settled. At least two others were still open in October 2026.

• SEC settlement. On 20 December 2024, Tai Mo Shan Limited, a Jump Crypto subsidiary, was ordered to pay about $123 million. The SEC found that the subsidiary negligently misled investors about how TerraUSD held its dollar peg, and that it acted as an underwriter for unregistered LUNA sales.
• Terraform administrator lawsuit. In December 2025, Todd Snyder, the administrator winding down Terraform Labs, sued Jump Trading, co-founder William DiSomma and former Jump Crypto president Kanav Kariya for $4 billion. A Jump spokesperson called the suit "a desperate attempt" to shift blame and said the firm would defend itself, The Block reported.
• Investor class action. In early September 2026, a federal judge in the Northern District of California ruled that Jump Trading must face most of the claims in a proposed class action by Terraform investors, according to Law360.

The claims in the open cases are allegations. No court has ruled on whether they are true.

Other risks are worth knowing about:

• Firedancer is still new code. The full client was the subject of an Immunefi audit competition with a $1 million prize pool, which ran from 9 April to 9 May 2026 and covered about 636,000 lines of C. Neodyme has also published a security audit of earlier versions. A Firedancer engineer told CoinDesk in May 2026 that the team wanted a gradual rollout until audits were complete.
• Solana depends on one company for its second client. Jump Crypto funds and staffs Firedancer. If Jump's priorities changed, the client would need a new home.
• Jump Crypto has conflicts of interest. The firm trades on Solana, invests in Solana projects and writes core Solana software. Read its research on market structure with that in mind.
• Leadership has changed under pressure. Kanav Kariya stepped down as president on 24 June 2024, days after Fortune reported a CFTC investigation into the firm.

Jump Crypto has no public on-chain programs listed on this profile, so there is no upgrade authority for us to report.

Who founded Jump Crypto, and how did it get here?

Jump Crypto grew out of Jump Trading, so its founders are Jump Trading's founders, Paul Gurinas and Bill DiSomma. The crypto team became a public brand in September 2021. Kanav Kariya, who joined Jump as an intern, led it as president until June 2024.

The years since have had sharp turns:

• August 2021: Pyth, the price oracle incubated at Jump, goes live on Solana.
• February 2022: Jump Crypto replaces 120,000 ETH after the Wormhole exploit.
• May 2022: TerraUSD collapses. Jump's earlier dealings with Terraform Labs become the subject of regulators and lawsuits.
• June 2024: Kanav Kariya leaves.
• December 2024: the Tai Mo Shan settlement with the SEC.
• June 2025: Jump Crypto publishes "(re)Introducing Jump Crypto" and resumes regular writing on its blog.
• December 2025: Firedancer is announced as live on Solana mainnet.
• September 2026: the Firedancer team sets an end date for Frankendancer.

Jump Crypto's website does not name a current head of the unit, so we have left that out.
