Coinbase Global, Inc., branded Coinbase, is an American publicly traded company that operates a cryptocurrency exchange platform. Coinbase is a distributed company; all employees operate via remote work. It is the largest cryptocurrency exchange in the United States in terms of trading volume. The company was founded in 2012 by Brian Armstrong and Fred Ehrsam. In May 2020, Coinbase announced it would shut its San Francisco, California, headquarters and change operations to remote-first, part of a wave of several major tech companies closing headquarters in San Francisco in the wake of the COVID-19 pandemic.

Although cryptocurrencies can assure anonymous trade in principle, Coinbase trades are not anonymous: registered users are required to provide their taxpayer identification, and the transactions are reported to the IRS. Also, although Coinbase offers more than 250 different cryptocurrencies to U.S. customers in 2023, it does not trade Monero and other cryptocurrencies with enhanced anonymity protection due to KYC requirements in accordance with anti-money laundering regulations.

Coinbase was founded in June 2012 by Brian Armstrong, a former Airbnb engineer. Armstrong enrolled in the Y Combinator startup incubator program and received a US$150,000 cash infusion. Fred Ehrsam, a former Goldman Sachs trader, later joined as a co-founder after noticing Armstrong's posts on Reddit. British programmer and Blockchain.info co-founder Ben Reeves was originally supposed to be part of the Coinbase founding team but parted ways with Armstrong just before the Y Combinator funding event, due to their different stands on how the Coinbase wallet should operate. The company is named after coinbase transactions, which are special transactions that introduce cryptocurrency into circulation in proof of work cryptocurrencies. In October 2012, the company launched the services to buy and sell bitcoins through bank transfers.

In May 2013, the company received a US$5 million Series A investment led by Fred Wilson from the venture capital firm Union Square Ventures. In December, the company received a US$25 million investment from the venture capital firm Andreessen Horowitz, Union Square Ventures (USV), and Ribbit Capital. Olaf Carlson-Wee, a graduate from Vassar College, was hired as the first employee in the same year.

In 2014, the company grew to one million users, acquired the blockchain explorer service Blockr and the web bookmarking company Kippt, secured insurance covering the value of bitcoin stored on their servers and launched the vault system for secure bitcoin storage. Throughout 2014, the company also partnered with Overstock, Dell, Expedia, Dish Network, and Time Inc. allowing those firms to accept bitcoin payments. In the same year, the company also added bitcoin payment processing capabilities to the traditional payment companies Stripe, Braintree, and PayPal. In January 2014, Coinbase Global, Inc. was incorporated in Delaware as a holding company for Coinbase and its subsidiaries. The corporate reorganization that saw Coinbase become a subsidiary of Coinbase Global was completed in April of that year.

In January 2015, the company received a US$75 million investment, led by Draper Fisher Jurvetson, the New York Stock Exchange, USAA, and several banks. Later in January, the company launched a U.S.-based bitcoin exchange for professional traders called Coinbase Exchange. In September, Coinbase began to offer services in Canada and Singapore.

In May 2016, the company rebranded the Coinbase Exchange, changing the name to Global Digital Asset Exchange (GDAX). In July, they added retail support for Ether. Also, in July, they announced they would halt services in August after the closure of Canadian online payments service provider Vogogo.

In January and then March 2017, Coinbase obtained BitLicense and was licensed to trade in Ethereum and Litecoin from the New York State Department of Financial Services (DFS). In November, Coinbase was ordered by the U.S. Internal Revenue Service to report any users who had at least US$20,000 in transactions in a year. On December 19, Coinbase listed Bitcoin Cash, and the Coinbase platform experienced price abnormalities that led to an insider trading investigation.

On February 23, 2018, Coinbase told approximately 13,000 affected customers that the company would be providing their taxpayer ID, name, birth date, address, and historical transaction records from 2013 to 2015 to the IRS within 21 days. In March, Coinbase appointed Emilie Choi, a former LinkedIn executive, as Vice President of Corporate and Business Development. She was promoted to the role of president and chief operating officer in May 2019. On March 26, 2018, Coinbase announced their intention to add support for ERC-20 tokens. On April 5, 2018, Coinbase announced that it had formed an early-stage venture fund, Coinbase Ventures, focusing on investment into blockchain- and cryptocurrency-related companies. On May 16, Coinbase Ventures announced its first investment in Compound Labs, a start-up building Ethereum smart contracts similar to money markets. On May 23, GDAX was rebranded as Coinbase Pro. Also in May, Coinbase launched Prime, a platform dedicated to institutional customers. In August, Amazon cloud executive Tim Wagner joined Coinbase as vice president of engineering. In September, Coinbase, along with Circle and bitcoin miner company Bitmain, was part of a consortium called Centre that launched a digital coin called USD Coin, pegged to the U.S. dollar.

In January 2019, Coinbase stopped all trading on Ethereum Classic due to a suspicion of an attack on the network. In February, Coinbase announced that it had acquired "blockchain intelligence platform" Neutrino, an Italy-based startup, for an undisclosed price. The acquisition raised concern among some Coinbase users based on Neutrino founders' connection to the Hacking Team, which has been accused of providing internet surveillance technology to governments with poor human rights records. On March 4, Coinbase CEO Brian Armstrong said his company "did not properly evaluate" the deal from a due diligence perspective and thus any Neutrino staff who previously worked at Hacking Team "will transition out of Coinbase." In April, a U.K. corporate filing stated that Coinbase's non-U.S. revenue grew 20 percent to €153 million (US$173 million) in 2018 resulting in a net profit of €6.6 million. Coinbase U.K. CEO Zeeshan Feroz said the company's non-U.S. operations accounted for nearly one-third of the company's overall revenue and Reuters estimated that the company's global revenue totalled "around $520 million" in 2018. In August, Coinbase announced that it was targeted by a hacking attack attempt in mid-June. This reported attack used spear-phishing and social engineering tactics (including sending fake e-mails from compromised email accounts and creating a landing page at the University of Cambridge) and two Firefox browser zero-day vulnerabilities. One of the Firefox vulnerabilities could allow an attacker to escalate privileges from JavaScript on a browser page (CVE-2019–11707) and the other, could allow the attacker to escape the browser sandbox and execute code on the host computer (CVE-2019–11708). Coinbase's security team detected and blocked the attack, the network was not compromised, and no cryptocurrency was stolen.

In May 2020, during the COVID-19 pandemic, the company announced it was shifting completely to remote work and would no longer recognize a formal headquarters. Also in May, the company announced the acquisition of New York-based digital asset trading firm Tagomi for a price between US$75 and $100 million. In June, Coinbase received internal backlash after CEO Brian Armstrong initially refused to make a statement about Black Lives Matter, citing the company's apolitical culture, but Armstrong later reversed his course on Twitter. In September, Armstrong published a blog post emphasizing that Coinbase would not engage in social activism, citing that such activism had hurt other technology firms such as Google and Facebook, and offered a severance package for those who disagreed with this direction. The company also faced complaints by employees saying they were treated unfairly due to their race or gender.

In October, Coinbase announced the launch of a Visa debit card program. In December, The New York Times reported that based upon data up to 2018 (already two years old as of the date of publication) women at Coinbase were paid an average of eight percent less than men at comparable jobs and ranks within the company, and Black employees were paid seven percent less than those in similar roles.

In March 2021, the company fell under review by the Office of Foreign Assets Control, with concerns that the company may have provided their blockchain service to blacklisted individuals or companies, noting that the nature of blockchain technology makes it "technically infeasible" to prevent specific users from making transactions.

Later, In March 2021, the company agreed to pay US$6.5 million to settle regulatory claims that it had reported misleading information about its trading volumes. Also in March, Coinbase announced that it was establishing a business presence in India and hiring employees for IT services, including engineering, software development and customer support operations. The company also announced plans to open a physical office in Hyderabad.

In April 2021, with its final earnings release before its April 14 direct listing, the company reported a nine-fold increase in first-quarter revenue, to US$1.8 billion, up from US$190.6 million the previous year. The jump was attributed to the increase in the price of bitcoin over that period.

On April 14, 2021, Coinbase became a public company on the Nasdaq exchange via a direct stock listing. Before the listing, Nasdaq set a reference price of US$250 a share, giving the company an estimated value of US$47 billion. At the end of its first day of trading, Coinbase closed at US$328.28 per share.

In May, the company's chief people officer published a blog post announcing that Coinbase was eliminating salary and equity negotiations during recruiting, citing salary disparities with women and minorities. The announcement said that "all employees in the same position, in the same location, receive the same salary and equity offer."

In June, Coinbase added Dogecoin to its tradable assets for Coinbase Pro users. In September, the U.S. Securities and Exchange Commission reportedly threatened to sue Coinbase if the company decided to launch a cryptocurrency lending product called Lend. The company initially responded in a blog post that it was confused for being singled out by the SEC, but later announced it had cancelled the planned launch. Technology publication TechCrunch covered the story and noted the existence of similar cryptocurrency lending products already on the market.

In November, Coinbase made its first acquisition in India by purchasing AI-powered support platform Agara for an estimated US$40–50 million. The company stated that it would utilize Agara's technology to automate its customer experience tools. On December 15 a display glitch vastly inflated balances such that numerous users were, albeit briefly, trillionaires.

Coinbase's 60-second commercial during Super Bowl LVI achieved viral status and was considered to be the most effective of any commercial during the game. The ad, credited to Accenture Interactive, cost US$13 million and featured only a black, screensaver-like screen with a bouncing color changing QR code. The code directed users to a web page advertising US$15 in free bitcoin for new accounts plus entry into a promotion for a sweepstakes to win three US$1 million prizes for bitcoin. The low-tech image evoked the retro look of the old DVD screensaver logo bouncing around the screen.

The advertisement had no narration and only music. The influx of users caused Coinbase's website to crash. Coinbase's landing page received 20 million hits in one minute. Its iOS app jumped from No. 186 to No. 2 in overall downloads after the advertisement. The ad was parodied later in the night by Meta (which posted its own, similar ad on social media to advertise a streaming Foo Fighters concert after the game). Meta quipped "Hopefully this doesn't break." The Super Bowl which has been nicknamed the "Crypto Bowl" also featured commercials by Crypto.com, eToro, and FTX on the American telecast.

In response to the 2022 Russian invasion of Ukraine, Coinbase blocked 25,000 cryptocurrency wallet addresses related to Russia.

Coinbase began operations in India in April 2022. The company initially relied on Unified Payments Interface to allow users to convert rupees to cryptocurrencies, but ceased using UPI after a statement released by the National Payments Corporation of India indicating it was "not aware of any crypto exchange using UPI". This statement forced Coinbase to suspend most of its business in India. Users in India cannot convert rupees into cryptocurrency but can trade between different cryptocurrencies.

In May 2022, Coinbase-backed Mara raised $23 Million to build an African crypto Exchange.

On June 14, 2022, the company announced it would be laying off approximately 18 percent of its workforce, about 1,100 full-time jobs, amid the global downturn in cryptocurrencies and services.

In August 2022, Coinbase announced a partnership with BlackRock, a venture which allows BlackRock clients to use their Aladdin investment management system to oversee their exposure to bitcoin along with other portfolio assets, and to facilitate trading on Coinbase's exchange.

Coinbase reported a net loss of US$1.1 billion in the second quarter of 2022, a record for the company. In October 2022, Coinbase entered into a partnership with Google Cloud Platform that would allow the latter's customers to pay for cloud services with cryptocurrencies supported by Coinbase Commerce. Coinbase also agreed to transfer its data-related applications from Amazon Web Services to Google Cloud.

On January 10, 2023, Coinbase announced it would be laying off around 950 employees, incurring restructuring expenses of up to US$163 million. Citing the possibility of "further contagion" following the collapse of the FTX exchange, Brian Armstrong said Coinbase would be "shutting down several projects where we have a lower probability of success."

In February 2023, Coinbase launched its own layer 2 blockchain on Ethereum, based on MIT-licensed OP Stack of layer-2 blockchain Optimism.

On 22 March 2023, Coinbase received a Wells notice from the U.S. Securities and Exchange Commission signalling that the SEC intended to begin an enforcement action over Coinbase's staking products. Coinbase responded by calling the investigation "cursory", and stated that it would continue to operate as usual. The next month, Coinbase sued the SEC asking a federal court to force the regulator to respond to a rulemaking petition the company submitted last year asking it to make clear regulations pertaining cryptocurrencies.

In June 2023, the SEC said it was suing Coinbase, alleging that the company had been acting as an unregistered broker, exchange and clearing agency since 2019, requesting that the company be "permanently restrained and enjoined" from doing so. The SEC also alleged that Coinbase never registered its staking service as required by US securities laws.

In April 2023, the company announced that its Coinbase Bermuda division had been licensed to operate cryptocurrencies in Bermuda. The next month, the company launched the Bermuda-based crypto derivatives exchange, named Coinbase International Exchange, allowing non-U.S. customers to trade bitcoin and Ethereum futures. In July 2023, CEO Brian Armstrong stated that the SEC demand Coinbase stop trading all assets excluding bitcoin and the firm refused, stating “It kind of made it an easy choice . . . let’s go to court and find out what the court says.”

Coinbase offers products for both retail and institutional cryptocurrency investors, as well as other related cryptocurrency products.

The company's products for retail traders include:

• Coinbase, an app used to buy, store and trade different cryptocurrencies

• Coinbase Card, a debit Visa card that allows customers to spend cryptocurrency
• Coinbase Earn, a cryptocurrency learning platform that rewards users with small amounts of altcoins for watching videos and taking quizzes to learn about them

The company develops an application programming interface (API) for developers and merchants to build applications and accept payments in digital currencies.

Coinbase operates as a remote-first company and has no physical headquarters. As part of its SEC filing to go public, the company reported 43 million verified users, 7,000 institutions, and 115,000 ecosystem partners in over 100 countries. It also reported net revenue of US$1.14 billion in 2020, up from US$483 million the previous year. The company also reported a net income of US$322 million after posting a loss in 2019. Out of the US$782 billion worth of assets on the crypto market, some $90 billion worth is held on the Coinbase platform.

In a May 2022 Form 10-Q filing, Coinbase stated that "because custodially held crypto assets may be considered to be the property of a bankruptcy estate, in the event of a bankruptcy, the crypto assets we hold in custody on behalf of our customers could be subject to bankruptcy proceedings and such customers could be treated as our general unsecured creditors".

On February 16, 2018, Coinbase admitted that some customers were overcharged in error for credit and debit purchases of cryptocurrencies. The problem was initiated when banks and card issuers changed the merchant category code (MCC) for cryptocurrency purchases earlier that month. This meant that cryptocurrency payments would now be processed as "cash advances", meaning that banks and credit card issuers could begin charging customers cash advance fees for cryptocurrency purchases. Customers who purchased cryptocurrency on their exchange between January 22 and February 11, 2018, could have been affected. At first, Visa blamed Coinbase, telling the Financial Times on February 16 that it had "not made any systems changes that would result in the duplicate transactions cardholders are reporting." However, the latest statement from Visa and Worldpay on the Coinbase blog clarifies: "This issue was not caused by Coinbase."

In March 2018, the Quartz news website reported that the number of monthly customer complaints against Coinbase jumped more than 100 percent in January of that year, to 889, citing official Consumer Financial Protection Bureau data, with more than 400 of those categorized as "money was not available when promised". The article also noted that the company was subsequently increasing its customer service staff to reduce wait times.

In December 2021, CNBC reported that Coinbase froze the cryptocurrency GYEN due to a sudden price spike, resulting in many traders losing money.

On July 22, 2022, a former Coinbase product manager, Ishan Wahi, along with Nikhil Wahi (Ishan's brother) and Sameer Ramani (a friend), was charged in the first-ever insider trading case in cryptocurrency by prosecutors for the Southern District of New York and the Securities and Exchange Commission. According to the complaint filed in SEC v. Wahi, Ishan Wahi allegedly shared information that certain tokens were about to be listed by Coinbase with Nikhil Wahi and Ramani, who then allegedly acted upon that information to make trades for an alleged illicit profit over US$1.5 million. According to federal prosecutors, Ishan Wahi purchased a one-way ticket to India upon being summoned by Coinbase to the company's Seattle office for a meeting. Wahi was subsequently intercepted by law enforcement from boarding a May 16 flight to India. Coinbase's chief security officer, Philip Martin, noted that the company provided prosecutors with information from an internal investigation.

On January 10, 2023, Nikhil Wahi was sentenced to ten months in prison after he admitted to making trades based on confidential information from Coinbase. U.S. District Judge Loretta Preska said Wahi's crime was "not an isolated error in judgment." Ishan Wahi originally pleaded not guilty but entered a guilty plea on February 7, 2023. On May 9, 2023, Ishan Wahi was sentenced to two years in prison and ordered to forfeit various crypto assets that he received in connection with the scheme. Ramani remains at large.
