Understanding the precise circulating supply of BNB is crucial for investors, developers, and enthusiasts within the cryptocurrency ecosystem. This guide provides a clear breakdown of the components and calculations involved in determining the current supply of BNB tokens.
The BNB Circulation Model
The BNB token operates across multiple chains, including BSC, Greenfield, and opBNB. This interconnected ecosystem relies on a sophisticated cross-chain communication architecture.
When BNB moves to Greenfield or opBNB, an equivalent amount is securely locked in specific smart contracts on the BSC. This mechanism ensures the total supply remains consistent and verifiable across all chains.
The original BNB Beacon Chain has been fully decommissioned. All its validators have ceased block production, and its assets have been transitioned to the BSC.
Understanding the BNB Burn Mechanisms
BNB employs several burn mechanisms to reduce its total supply over time. These processes are automated, community-driven, and part of official protocol upgrades.
Real-Time Burning (BEP-95)
BEP-95 introduced a real-time burn mechanism. A portion of the gas fees from every block on the BSC is permanently destroyed. The exact ratio is determined through governance by BSC validators. You can monitor the ongoing burn amount directly on popular blockchain explorers.
The Auto-Burn System
Binance employs an automated system designed to reduce the total supply to 100 million BNB. The amount burned each quarter is algorithmically adjusted based on the price of BNB and the number of blocks produced on the BSC during that period.
Community-Led Burns
Many community-driven projects contribute to the deflationary pressure by voluntarily sending BNB to a publicly verifiable dead address. This is a separate initiative from the protocol-level burning.
The Pioneer Burn Program
This initiative addresses cases of lost funds. In eligible circumstances, users who have lost access to their BNB can be reimbursed. The lost coins are then counted toward the official burn total, compensating users while reducing circulation.
Calculating the Total BNB Burned
To find the exact amount of BNB removed from circulation, you must aggregate the following components:
- Auto Burn: The sum of all BNB burned through the quarterly Auto-Burn system.
- Real-Time Burn: The cumulative amount burned via BEP-95, visible on blockchain explorers.
- Community Burn: This is calculated by checking the balance of the public dead address and subtracting the real-time burn and any other official burn transactions.
- Beacon Chain Fusion Burn: This includes 110,000 BNB from the decommissioned Beacon Chain validators, which is permanently locked.
The formula is:
Total Burned = Auto Burn + Real-Time Burn + Community Burn + Beacon Chain Fusion Burn

Determining the Circulating Supply
The final calculation for the circulating supply starts with the maximum supply and adjusts for all burned tokens and other permanent removals.
The core formula is:
Total BNB Circulation = 200,000,000 - Total Burned + (2,000,000 - 1,020,000) - 6,823
Supplementary Notes on the Calculation
- The 2,000,000 BNB refers to assets minted by a hacker during a past bridge incident. Of this, 1,020,000 BNB was successfully frozen and is treated as permanently burned.
- The 6,823 BNB represents funds irrevocably locked in a smart contract due to user error. This amount is also considered permanently out of circulation.
- The 110,000 BNB from the Beacon Chain Fusion is permanently locked as part of the network upgrade and is counted as burned.
Frequently Asked Questions
What is the purpose of burning BNB?
Burning BNB removes tokens from permanent circulation, creating a deflationary pressure on the supply. This mechanism is designed to increase the scarcity of the token over time, potentially supporting its long-term value in conjunction with network utility and demand.
How can I verify the current burned amount myself?
You can independently verify the numbers by using a BSC block explorer. Check the balance of the known burn address for community burns and review the transaction history for the official Auto-Burn events. The real-time burn from BEP-95 is also recorded on every block.
What is the difference between Auto-Burn and real-time burn?
Auto-Burn is a quarterly, algorithmic adjustment that burns a calculated amount to meet supply reduction targets. Real-time burn is a continuous process that destroys a portion of every block's gas fees instantly, as governed by BEP-95.
Are all burned BNB sent to the same address?
No. The real-time burn and Auto-Burn are handled by the protocol itself. Community-led burns are voluntarily sent to a public dead address. It's important to distinguish between these different flows when calculating the total.
What is the final target for the total BNB supply?
The automated burning mechanisms are designed to systematically reduce the total supply of BNB until it reaches 100 million tokens. This is a long-term goal that will be achieved through the combination of all burn processes.
Does staking or locking BNB reduce the circulating supply?
No. Staking or temporarily locking BNB in DeFi protocols does not equate to burning. These tokens are only temporarily removed from the active trading supply but are not permanently destroyed and can re-enter circulation later.
