Crypto Infrastructure Companies: The Private Firms Behind Digital Assets

Behind every crypto trade, wallet transfer and stablecoin payment sits a layer of infrastructure: software that connects applications to blockchains, custodians that safeguard assets, analytics firms that trace funds for compliance, on-ramps that convert money into crypto, and issuers that create stablecoins. As crypto moved from a niche to a regulated part of finance, these infrastructure companies became some of the most valuable private firms in the industry. This guide ranks them by sourced valuation, explains what each segment does and covers the risks investors should weigh.

Every company in the table links to a full profile with its sourced valuation, funding history and investors. We include private companies that provide infrastructure, services or wallets rather than only trading. Exchanges such as Kraken are included because they also offer custody and infrastructure. Many valuations date from the 2021–2022 boom and should be read with their dates in mind. Our guide to the largest private crypto companies provides a broader ranking.

The ranking

Payments and stablecoins: Ripple and Paxos

Ripple builds payment infrastructure for financial institutions and issues its own stablecoin, and is the most valuable company in this ranking at US$50 billion, set by a March 2026 share buyback. Paxos issues stablecoins for itself and for partners, most notably PayPal USD, under its regulatory licences. Stablecoins have become one of crypto's most practical uses, enabling fast, low-cost dollar transfers worldwide. New US stablecoin legislation created a federal framework for issuers, encouraging banks and payment companies to explore their own tokens.

Exchanges and brokers: Kraken

Kraken, one of the oldest crypto exchanges, offers trading, custody, staking and other services, and was valued at US$20 billion in late 2025; reports in April 2026 put a new round at about US$13.3 billion. Exchanges have increasingly become infrastructure providers, offering services to other businesses and expanding into traditional assets.

Developer platforms: Alchemy and Consensys

Alchemy provides APIs and tools that developers use to build blockchain applications, and was valued at US$10.2 billion in 2022. Consensys makes the MetaMask wallet, the Infura node service and the Linea network, and has been preparing for a possible IPO. These companies supply the picks and shovels of blockchain development.

Custody and security: Fireblocks, Anchorage Digital and Ledger

Fireblocks provides technology that lets exchanges, banks and fintechs secure and move digital assets, and was valued at US$8 billion in 2022. Anchorage Digital operates a federally chartered crypto bank offering custody, staking and stablecoin services; Tether invested at a US$4.2 billion valuation in 2026. Ledger, based in France, makes hardware wallets for individuals and businesses. Secure custody is essential for institutional adoption, especially after the collapse of FTX showed the dangers of mixing custody and trading.

Compliance and analytics: Chainalysis

Chainalysis traces cryptocurrency flows for governments, exchanges and banks, helping fight money laundering, sanctions evasion and fraud. It was valued at US$8.6 billion in 2022. As regulation expands, every regulated crypto business needs transaction monitoring and screening, creating steady demand.

Wallets and on-ramps: Phantom and MoonPay

Phantom is a self-custody wallet that began on Solana and now supports multiple blockchains, valued at US$3 billion in 2025 with about 15 million monthly users. MoonPay lets users of wallets and applications buy and sell crypto with cards and bank transfers, valued at US$3.4 billion in 2021. Wallets are becoming the main interface for on-chain finance, while on-ramps connect crypto to traditional money.

How the infrastructure stack fits together

Consider a user buying a stablecoin and sending it to a friend abroad. They open a wallet such as Phantom or MetaMask and use an on-ramp such as MoonPay to buy the stablecoin with a card. The stablecoin was issued by a company such as Paxos or Circle and is backed by reserves. The wallet connects to the blockchain through node infrastructure from providers such as Alchemy or Infura. If the recipient later cashes out through an exchange, that exchange screens the incoming funds using analytics from Chainalysis or a competitor, and holds customer assets with custody technology from Fireblocks or a custodian like Anchorage. Each layer is a business, and each must work reliably for the system to function.

Regulation as a growth driver

For years, unclear rules held back institutional crypto adoption. Recent changes, including US stablecoin legislation, the European Union's Markets in Crypto-Assets regulation and a shift in US regulatory posture, have made it easier for banks, asset managers and payment companies to use crypto. Infrastructure companies with licences and compliance capabilities benefit most, because new institutional entrants need regulated partners. At the same time, regulation raises costs and can favour large incumbents.

Valuations and market cycles

Crypto infrastructure valuations peaked in 2021 and early 2022, when many companies raised at high prices. The market downturn in 2022, including the collapse of FTX, led to layoffs and lower valuations across the industry. Some companies have since raised at higher prices, such as Anchorage, while others have not set new prices. Public listings by companies such as Circle, and IPO plans from others, have provided benchmarks. Investors should check the date of each valuation and consider how much the market has changed.

How to evaluate a crypto infrastructure company

Useful questions include: how much revenue depends on trading volumes versus recurring fees? Which licences does it hold, and in which markets? How concentrated are its customers or partners? How does it protect against hacks and fraud? Is its technology tied to a single blockchain or broadly compatible? And how would a crypto downturn affect its business?

Risks

Crypto infrastructure companies face market cycles that affect trading volumes and asset values; security breaches that can cause large losses; regulatory changes; competition from traditional financial institutions entering the market; and dated valuations. Stablecoin issuers face interest rate risk, as falling rates reduce reserve income. Concentration among a few large partners is common.

What to watch

Watch for IPOs from Consensys, Kraken and Chainalysis, stablecoin growth, bank adoption of crypto services, and new funding rounds that update 2021–2022 valuations. Our guides to the largest private fintech companies and cross-border payments companies provide related context.

Key takeaways

Crypto infrastructure spans payments, exchanges, developer platforms, custody, analytics, wallets and on-ramps. Ripple and Kraken lead by valuation, while Alchemy, Chainalysis, Fireblocks and Consensys were among the most valuable in the 2021–2022 boom. Regulation and stablecoins are driving a new phase of growth, but market cycles and security remain central risks.

Institutions enter crypto

The launch of spot Bitcoin exchange-traded funds in the United States in 2024 marked a turning point for institutional crypto adoption. Large asset managers began offering crypto exposure to mainstream investors, which required custodians, trading desks and compliance infrastructure. Banks began exploring custody and stablecoin services, and payment companies integrated crypto features. Each new institutional entrant needs infrastructure partners, which has supported demand for custodians such as Anchorage Digital, technology providers such as Fireblocks and analytics firms such as Chainalysis. Institutions typically demand regulated partners, audited controls and insurance, raising the bar for infrastructure providers.

Tokenization of real-world assets

Tokenization means representing ownership of assets such as government bonds, money market funds, real estate or private credit as tokens on a blockchain. Supporters argue that tokenized assets can settle faster, trade around the clock and be used more flexibly as collateral. Large asset managers have launched tokenized funds, and infrastructure companies provide issuance, custody and compliance services. Paxos's tokenized gold product is an early example. Tokenization is still small relative to traditional markets, but it is one of the areas where crypto infrastructure and traditional finance are converging most quickly.

Security incidents and their impact

Crypto infrastructure is a constant target for hackers. Exchanges, cross-chain bridges and wallets have suffered large thefts, sometimes attributed to state-sponsored groups. Each major incident reinforces the importance of secure custody, multi-party approvals and transaction monitoring, and can lead to stricter regulation. For infrastructure providers, a strong security record is essential to winning institutional clients, while a single serious breach can damage a brand for years.
