About UNUS SED LEO (LEO)
UNUS SED LEO is a utility token created for Bitfinex and the wider iFinex ecosystem. LEO can be used for supported platform benefits, while iFinex’s repurchase-and-burn mechanism gradually removes tokens from circulation over time.
The token launched in 2019 and has since become closely tied to activity across Bitfinex and other iFinex services. This page explains LEO’s origins, utility, supply model and burn mechanism, alongside the current LEO token price and key market data.

THE WHITEPAPER
THE TOKEN SALE
THE TRANSPARENCY DASHBOARD
When Was UNUS SED LEO Created?
iFinex introduced UNUS SED LEO in May 2019 through a private token sale. Unus Sed Leo Limited issued the token for use across Bitfinex and other supported iFinex products and services.
Bitfinex completed the sale in under one week and received approximately $1 billion in Bitcoin, USD and USDt. The company launched its transparency initiative the following month to publish information about platform revenue and subsequent LEO burns.
The Private Token Sale Was Completed
Bitfinex completed the private sale in under one week, exchanging the outstanding LEO tokens for approximately $1 billion in Bitcoin, USD, and USDt.
The Transparency Dashboard Was Launched
Bitfinex introduced the LEO Transparency Initiative and a public dashboard covering platform revenue and subsequent token burns.

LEO Evolution
LEO developed from a fee-focused exchange token into a broader utility asset within the Bitfinex and iFinex ecosystem. Its original benefits included trading, lending, deposit and withdrawal fee reductions, while its repurchase-and-burn program introduced a continuing mechanism for reducing the outstanding supply.
Since 2019, Bitfinex has added burn reporting, expanded account-based benefits and updated LEO’s supported network infrastructure. Bitfinex removed trading fees from eligible products in 2025, which ended the corresponding LEO discount, but other benefits and the repurchase-and-burn framework continued.
The LEO Transparency Dashboard Launched
Bitfinex introduced the LEO Transparency Initiative and a public dashboard covering platform revenue and subsequent token burns.
LEO Reached 20 Million Tokens Burned
By August 4, Bitfinex had reported that the repurchase-and-burn program had permanently removed its first 20 million LEO from supply.
EOS-Based LEO Moved to Vaulta
Bitfinex moved the EOS-based version of LEO to Vaulta following the network’s rebrand. Users could continue converting between the Vaulta and ERC-20 versions through Bitfinex.
Bitfinex Changed LEO’s Fee Utility
Bitfinex removed maker and taker trading fees from eligible products, ending the associated LEO trading-fee discount. Other benefits continued, and the repurchase-and-burn terms remained unchanged.

How Does LEO Work?
LEO functions as a utility token across supported Bitfinex and iFinex services. Eligible users can hold LEO in a verified Bitfinex account to access benefits based on the platform’s current rules and the value or amount of LEO held.
iFinex also repurchases LEO under its revenue-based burn framework and permanently removes completed burns from supply. The market still determines the LEO price, and a lower token supply does not guarantee that its value will rise.
01
Keep LEO in a Supported Account
Eligible users hold LEO in a verified Bitfinex account. The platform calculates available benefits according to the user’s qualifying balance and current account requirements.
02
Apply the Available Platform Benefits
Qualifying holders may receive supported benefits such as lending-fee reductions, deposit and withdrawal discounts, affiliate multipliers or limited fee-free fiat withdrawals. Availability depends on the current Bitfinex terms.
03
Buy Tokens From the Market
Under the established framework, iFinex and its affiliates repurchase LEO using an amount equal to at least 27% of the previous month’s qualifying consolidated gross revenue.
04
Remove Repurchased LEO From Supply
iFinex permanently removes completed burns from the outstanding token supply and reports burn activity through the LEO transparency system.
What Shapes the LEO Price?
The LEO price reflects buying and selling across the markets where the token trades. Demand, available liquidity and the number of tokens in circulation can influence its value, while iFinex’s repurchase and burn program gradually reduces the outstanding supply.
Developments involving Bitfinex and iFinex can also affect the LEO token price. Changes to token utility, company operations, regulation, market access and wider cryptocurrency conditions may alter demand or trading activity.
Token Supply and Burns
iFinex periodically repurchases and burns LEO under the framework described in the token white paper. Burns permanently reduce the outstanding supply, but they do not guarantee that the price will rise.
Market Demand
Demand can change as traders increase or reduce their exposure to LEO. The relationship between available buyers and sellers determines the price at which trades execute.
Market Liquidity
LEO trades across fewer markets than many major cryptocurrencies. Limited order-book depth can allow relatively small trades to produce larger price movements or greater slippage.
Bitfinex and iFinex Utility
Eligible users can access supported benefits connected to the Bitfinex and iFinex ecosystem. Changes to these benefits may influence demand for LEO.
Company and Regulatory Developments
Announcements, legal proceedings, recoveries and regulatory decisions affecting Bitfinex, iFinex or their affiliates can influence market expectations and access to LEO.
Broader Market Conditions
Changes in cryptocurrency prices, risk appetite and global financial conditions can influence demand for exchange-related tokens such as LEO.
What Is the Price of LEO?
LEO is currently priced at $9.33 USD, down 0.26% over the past 24 hours. The live LEO snapshot above provides its market capitalization, trading volume, circulating supply and other current market data.
Will LEO Go Back Up?
No one can determine whether LEO will rise or return to a previous price. Earlier price movements do not guarantee future performance.
Future results will depend on market demand, liquidity, token utility, supply burns, developments involving iFinex and wider cryptocurrency conditions. A reduction in supply does not automatically produce an increase in price.
Is LEO Still Used?
LEO remains the utility token of the iFinex ecosystem. Eligible users can access supported benefits involving selected Bitfinex services, while iFinex continues operating the token’s repurchase and burn program.
Available benefits depend on the service, account status and jurisdiction. Bitfinex ended LEO trading-fee discounts when it introduced zero trading fees for eligible products in December 2025, although other supported benefits may remain available.
Can You Cash Out LEO for Real Money?
Yes. You can sell LEO for government-issued currency through a supported exchange or financial service where that option is available. If a service does not offer a direct fiat market, you may need to exchange LEO for another supported asset before withdrawing the proceeds.
The amount you receive depends on the LEO price when the order executes, the available liquidity and any trading, conversion, network or withdrawal fees. Verification requirements, account limits and available withdrawal methods also vary by provider and jurisdiction.
Select a Service That Supports LEO
Select a service that supports LEO trading and your preferred withdrawal method. Check its jurisdictional restrictions, verification requirements, supported markets and available token networks.
Send Tokens to the Matching Address
Choose the LEO network supported by the receiving service and send the tokens to the matching deposit address. Confirm the address, network and any required memo before authorizing the transfer.
Place the Order
Place an order to sell LEO for fiat currency or another supported asset. The execution price can differ from the displayed reference price because of market movement, order-book depth and slippage.

CASH-OUT CHECKLIST

These details affect how much money you receive, how quickly it arrives and whether the withdrawal is available in your location.
