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. A Jump Crypto subsidiary agreed to pay about $123 million to settle SEC charges over TerraUSD in December 2024, and related lawsuits were still open in November 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 on 13 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 consensus and the rest. The team announced the full client live on mainnet at Breakpoint on 12 December 2025, The Block reported. On 16 October 2026, Jump Crypto wrote that Firedancer secured about 15% of Solana's stake.

The Firedancer profile goes deeper on how the client works and who runs it. For the engineers' own story, see our summary of Michael McGee on the state of Firedancer.

Firedancer, Frankendancer and Alpenglow in October 2026

Solana switched to a new consensus system, Alpenglow, on 21 October 2026, Anza announced. Consensus is how validators agree on which blocks are final. The switch ended the Frankendancer era. If you want to run Jump Crypto's code, you now run the full Firedancer client.

• Frankendancer is no longer supported. In September 2026 the Firedancer team said it would drop the hybrid when Alpenglow arrived, Crypto Briefing reported. Frankendancer relied on Agave's old consensus code, which Alpenglow replaces.
• Full Firedancer runs on Alpenglow. Support came in release v26.10.2 on 14 October. Its release notes say Firedancer would not support the move from TowerBFT to Alpenglow itself. Instead it can write an Agave-compatible vote history file, so an operator can fail over to Agave safely.
• Fixes kept coming. The team shipped mainnet releases on the day of the switch and again six days later, listed on its releases page.

We covered the day Alpenglow went live and the test run before it.

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 a paper on PropAMMs in April 2026. The paper argues that on SOL/USDC and SOL/USDT in March 2026, most PropAMM fills were cheaper for users than the best centralized exchange rates. 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. In May 2026, Securitize, Jump Trading Group and Jupiter JUP$0.260+21.0% launched regulated trading in tokenized stocks on Solana. Jump supplied the liquidity through its PropAMM. In October 2026, Securitize named Jump Trading as a market maker for Securitize Stocks. Securitize has since doubled the list of stocks on offer, as we covered in our report on the expansion.

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$0.067+3.8% 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, the Jump staff working on Pyth left to found Douro Labs, which now builds it, Bloomberg reported. Jump Crypto stayed on as a Pyth data provider.
• Wormhole W$0.011+3.9% 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$0.023+1.8% 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 research: quantum safety, Falcon and AI security

Jump Crypto publishes research on its blog, mostly about Solana, cryptography and market structure. Recent posts cover how Solana could prepare for quantum computers and how the team uses AI to find bugs. This is research from a trading firm, so read its market-structure work with that in mind.

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.

In late October 2026 the blog turned to AI. Josh Siegel wrote a guide to giving AI coding tools such as Claude and Codex the context they need to write Solana programs. Charles Moyes described how Jump sandboxes the AI agents it uses to audit Firedancer's code and build crash tests. The sandbox keeps those agents from reaching the wider network.

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, and Jump Crypto took part, according to Crypto Briefing. Navra, founded by Mike Cagney, is an AI-based trading screen that reaches many blockchain venues.

Jump Trading has also bought into prediction markets. It took small stakes in Kalshi and Polymarket in February 2026, Crypto Briefing reported, citing Bloomberg. Its Polymarket stake grows with the trading capacity Jump supplies in the US.

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 Jump Crypto leaving crypto? The pullback and the return

Jump Crypto has not left crypto. It cut back after the TerraUSD and FTX collapses in 2022, and has been rebuilding since. Stories about Jump "moving away from crypto" describe that earlier retreat. The firm still trades, ships Firedancer releases and backs new projects.

Jump lost nearly $300 million when FTX failed and then pulled back from US crypto trading, Crypto Briefing reported, citing CoinDesk. The same March 2025 report said Jump was reviving its US crypto desk. It was hiring crypto engineers and adding policy roles. In June 2025, Jump Crypto published "(re)Introducing Jump Crypto" and started posting on its blog again.

The record since points the same way. Jump Crypto runs a PropAMM on Solana, makes markets in tokenized stocks, and pays outside researchers to find bugs in Firedancer.

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, sold in late September 2026, belongs to Jumper, an unrelated cross-chain app.

Jump Crypto matters most to three groups:

• Validator operators choosing between Firedancer and Agave. With Frankendancer retired at the Alpenglow switch, Firedancer is now the only way to run Jump's code.
• 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, researchers and security researchers who work near market structure, validator software or cryptography, where Jump Crypto invests, publishes and pays bug bounties.

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. Most of it goes back to the fall of the TerraUSD stablecoin. One case is settled. Several others were still open in November 2026.

• SEC settlement. In December 2024, Tai Mo Shan Limited, a Jump Crypto subsidiary, was ordered to pay about $123 million. The SEC found that in May 2021 the firm negligently misled investors about how well TerraUSD worked. It also found the firm sold LUNA as an underwriter without the needed filing.
• 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 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.
• Price manipulation suit. In August 2026, a federal appeals court in Chicago refused Jump Trading's bid to move a separate investor case into private arbitration. That case claims Jump manipulated the price of a cryptocurrency.

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

Firedancer security: audits, the bug bounty and AI-written reports

Firedancer is still young code that secures a large share of Solana's stake. The full client went through an Immunefi audit competition with a prize pool of up to $1 million in spring 2026. Its scope was the v1.0 Firedancer binary and the code it reaches, about 636,000 lines of C.

The contest drew 809 reports, Jump Crypto wrote on 16 October 2026, and 127 were unique security findings. The team wrote that "nearly every submission was either discovered or written by an agent", meaning an AI tool. Neodyme has also published a security audit report on Firedancer code; check which version and components it covers before treating it as a review of today's client.

On the same day the team opened a bug bounty at bounty.firedancer.io. It pays double rewards, and triple for Alpenglow bugs, until 20 November 2026. Each report costs 1 SOL, which is burned. We covered the launch in our report on the Firedancer bug bounty.

Other Jump Crypto risks to know

• 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 who runs it now?

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

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 later draw an SEC case and lawsuits.
• June 2024: Kanav Kariya leaves.
• December 2024: the Tai Mo Shan settlement with the SEC.
• March 2025: Jump is reported to be rebuilding its US crypto desk.
• 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.
• October 2026: Firedancer opens its own bug bounty, and Alpenglow goes live on 21 October, ending Frankendancer support.
