FalconX is an institutional crypto prime broker that serves funds, trading firms and other large market participants. Many of them use it for trading, derivatives and credit. Exchanges, brokers, fintechs, payment firms and corporate treasuries often need a different toolkit, with aggregated spot liquidity, fiat settlement and accounts they can split by business line. That need sends them to look for a FalconX alternative.
This guide compares FalconX with CEX.IO Prime across liquidity, settlement, connectivity, custody and regulation, so you can see which platform suits your order flow.
What is FalconX, and how does it work?
FalconX is a digital asset prime brokerage that gives institutions trading, financing and custody through one relationship. The company has operated since 2018. Its client list covers asset managers, hedge funds, family offices, venture funds, miners, protocols, banks and fintechs. On its website FalconX reports more than $2.5 trillion in trading volume since launch.
The product line spans five areas:
- Trading in spot, derivatives and foreign exchange, with an execution management system.
- Financing through margin loans, OTC lending, structured products and yield products.
- Custody and staking, linked to the trading account.
- Direct Market Access, which lets clients trade on external venues with cross-margining.
- ETF solutions for fund issuers, including liquidity provision and hedging.
FalconX 360 ties these products together as one platform for electronic trading, financing and operations. The company earns revenue mainly from trading spreads and financing fees.
Options are a strong area for FalconX. The company says it ranks first in institutional options block volume on Paradigm, a network for crypto options block trades. In 2025 it bought Arbelos Markets, a crypto derivatives trading firm, and 21Shares, an issuer of crypto exchange-traded products.
These strengths make FalconX a natural fit for funds that trade derivatives and use credit. Businesses that run on spot liquidity, fiat rails and operational accounts often compare it with other providers.
Why look for a FalconX alternative?
A FalconX alternative is a provider that covers institutional crypto execution with a different product mix. Companies usually start the search for one of these reasons:
- They run an exchange, brokerage or app and need aggregated spot liquidity behind their own order flow.
- They move money in USD, EUR or GBP and want fiat and crypto settlement on the same account.
- They serve several business lines or end clients and need sub-accounts, address whitelists and approval rules.
- They trade large blocks and want an account manager who quotes a firm price.
- They want a second liquidity provider so their operations do not depend on a single counterparty.
Each of these needs comes from the client’s business model. A hedge fund and a payment institution can both trade crypto every day and still need very different things from a provider.

CEX.IO Prime
CEX.IO Prime is the institutional platform of CEX.IO Group. It gives a business one account for liquidity, OTC execution, fiat and crypto settlement, custody and reporting. CEX.IO has run a crypto exchange since 2013 and has kept it open through every market cycle since then. Prime opens that same infrastructure to institutions.
Aggregated liquidity
Prime pulls liquidity from more than 15 trading venues, including top-tier liquidity providers and exchanges, into one order book. Its routing engine sends each order to the best available price and splits large orders across venues to cut market impact. The client receives one consolidated fill at one price. When a pair has no direct market, Prime converts through an intermediate asset, so a wallet app can still let users swap between less common tokens.
Clients pick the execution style for each trade. They can trade on the live order book, use Instant Convert to lock a fixed price for a short window, send an RFQ to get a quote on a larger size, or hand a block to the desk through assisted OTC execution. Every trade lands on the same account and the same ledger, whatever route it takes.
OTC desk
The Prime OTC desk executes large or negotiated trades away from the public order book. Prime enables OTC access for each client individually. A trade follows six steps:
- The client sends its account manager a request with the asset, side, size and settlement asset.
- The account manager sources a price from the trading desk or a liquidity provider.
- The manager presents a quote with a validity period.
- The client confirms in writing inside that period.
- The manager executes the trade off the order book.
- The ledger settles the trade on the client’s account, and the trade appears in standard reporting.
The written exchange serves as the audit record. It gives the client an auditable workflow for internal governance, because compliance teams can trace every block back to a confirmed quote.
Fiat and crypto settlement
Prime keeps fiat and crypto on one account. It handles USD, EUR and GBP over SWIFT, SEPA, SEPA Instant and Faster Payments, along with domestic and international wires. On the crypto side it settles stablecoins, BTC, ETH and other assets on more than 60 networks. Fiat and crypto settle the same day.
This setup lets a payment firm offer crypto to its customers without holding crypto on its own books. An EU electronic money institution can fund Prime in euros, convert to USDC through the on-ramp and send the USDC to its users’ wallets. Its own accounts stay in fiat the whole time.
Two Prime clients can also pay each other through CEX.IO Pay. These internal transfers arrive instantly and cost nothing, which helps groups that move working capital between their own entities or pay suppliers who already use Prime.
Accounts, custody and control
Prime custody uses multi-party computation (MPC) with quorum signing, which splits signing power between several parties. Each client can open sub-accounts for a business line, a trading strategy or an end user, and Prime keeps the holdings of each sub-account separate. Withdrawals go only to whitelisted addresses. The client chooses single, dual or threshold approvals, and role-based access, SSO and 2FA decide who can act on each account.
Every operation posts to one ledger with consistent identifiers. Finance teams pull account and sub-account statements through the interface or the API and feed them into their own accounting and audit systems. Batch withdrawals take up to 10,000 rows, so a business that pays out to many wallets can send them in bulk.
Financing
Prime arranges financing case by case. After due diligence and a risk review, a client can open a trading credit line with same-day settlement or take a loan against collateral in fiat, stablecoins, BTC or ETH. A market maker can use a credit line to keep quoting through a busy window, and a long-term holder can raise working capital without selling the asset.
Connectivity, security and licences
Prime connects through FIX 4.4, REST and WebSocket, with webhooks for event alerts and a sandbox for tests before production. Teams that prefer a screen work in the web portal. Every client gets a dedicated account manager, and the institutional desk runs 24/7.
Prime publishes the minimum and maximum order size, lot size and price precision for every pair on prime.cex.io/markets. A desk can check these limits before it signs anything.
CEX.io LTD received a PCI DSS Level 1 certificate as a service provider in March 2026. CEX.IO Group entities also hold registrations and licences in several jurisdictions. These include FinCEN MSB registration and money transmitter licences in US states, FCA registration in the UK, VASP registration in Spain, FINTRAC MSB registration in Canada and a DABL licence in Bermuda. The CEX.IO Licenses and Registrations page names the group’s legal entities.
CEX.IO Prime Pros and Cons
Our review of Prime shows a platform built for companies that run crypto as part of daily operations. Its gaps sit in derivatives, an area FalconX covers well.
Pros:
- One account for liquidity, OTC, fiat settlement, custody and reporting.
- Same-day settlement in USD, EUR and GBP.
- FIX 4.4, REST and WebSocket with a sandbox.
- Sub-accounts, whitelisting and approval rules for each business line.
- Public order limits for every trading pair.
- PCI DSS Level 1 certification and an exchange track record since 2013.
Cons:
- Prime has no options or futures desk.
- Prime does not publish a minimum size for OTC trades.
- OTC access and financing need separate approval.
Why do businesses choose CEX.IO Prime?
Prime puts liquidity, fiat rails, custody and reporting behind one counterparty and one ledger. A business that works with separate vendors for each of these goes through separate onboarding, separate compliance checks and separate statements. Prime cuts that down to one relationship.
A neobroker can map each user to a sub-account and route orders through the Prime API. A regional exchange can back its own order book with Prime liquidity over FIX. A treasury team can trade, convert and settle on Prime and pull one monthly statement per sub-account for its ERP. The same account, the same reports and the same account manager serve all of these flows.
FalconX
FalconX is a crypto prime broker for funds and trading firms. It offers trade execution, liquidity, credit and clearing, and its products reach deep into derivatives.
FalconX Bravo, Inc. holds swap dealer registration with the US Commodity Futures Trading Commission (CFTC) and membership in the National Futures Association. Through this entity FalconX offers options and forwards to US clients. In June 2026 FalconX Limited received authorisation from the Malta Financial Services Authority as a crypto-asset service provider under MiCA, which lets it serve clients across the EU and EEA.
Credit forms a large part of the business. FalconX provides margin loans, OTC lending and structured products, and in August 2026 it announced a $1 billion warehouse financing facility with Ethena. In the US, clients can hold assets with Fireblocks Trust Company, a qualified custodian under NYDFS supervision, and trade and borrow against them through one interface. Prime Connect gives traders access to exchange liquidity with off-exchange settlement, so their assets stay off the exchange.
The company keeps growing through deals. Beyond Arbelos Markets and 21Shares, it bought the blockchain connectivity firm bloXroute in July 2026, and in May 2026 media reported a confidential IPO filing with the SEC.
FalconX Pros and Cons
FalconX suits institutions that trade options, swaps and leveraged positions at scale. Companies with simpler spot and payments needs may use only part of what it offers.
Pros:
- Deep expertise in crypto options and derivatives.
- Large financing and lending capacity.
- CFTC swap dealer registration in the US and a MiCA licence in the EU.
- Qualified custody for US clients through Fireblocks Trust Company.
- ETP and ETF solutions through 21Shares.
Cons:
- The FalconX website lists no minimums or fee schedules.
- The company states that some of its products fall outside MiCA and may not reach EEA clients.
- A business that only needs spot liquidity and fiat settlement may pay for a wider product set than it uses.
CEX.IO Prime vs FalconX Head to Head
Liquidity and execution
Both providers aggregate liquidity for institutional clients. Prime gives one order book across 15+ venues, with RFQ, Instant Convert and an OTC desk on the same account. FalconX offers electronic trading through FalconX 360 and an execution management system. The choice comes down to how you want to access the market.
Fiat settlement
Prime lists its fiat rails in full and settles USD, EUR and GBP the same day. FalconX offers FX trading and flexible settlement and names no specific rails on its website. A payment firm or fintech with daily fiat flows will find a clearer fit in CEX.IO Prime.
Derivatives and financing
FalconX leads here. Its swap dealer registration, options volume on Paradigm and lending book give it a clear edge for funds that trade derivatives. Prime offers credit lines and collateralised loans per client, and it has no options desk. FalconX wins this category.
Custody and operations
Prime builds custody into the account, with MPC, sub-accounts, mandatory whitelists and approval rules. FalconX integrates custody with trading and, for US clients, works with Fireblocks Trust Company as a qualified custodian. The better option depends on your jurisdiction and on how many business lines you need to separate.
Transparency of terms
Prime publishes order limits for every pair on a public page. The FalconX website lists neither minimums nor fees. Teams that want to check terms before the first call will find more public detail at CEX.IO Prime.
