What Is the Binance SAFU Fund?
The Secure Asset Fund for Users (SAFU) is Binance's emergency insurance fund, established on July 3, 2018. It acts as a financial safety net designed to protect users in extreme cases such as security breaches or critical system failures.
Binance allocates 10% of all trading fees to the SAFU fund. These assets are stored in segregated cold wallets, completely separate from Binance's operational funds. The wallet addresses are publicly available, allowing anyone to verify the fund's holdings on-chain at any time.
Cold Wallet Storage
SAFU assets are kept in segregated cold wallets, isolated from Binance's hot wallets and operational accounts.
On-Chain Verifiable
Public wallet addresses allow anyone to verify fund balances on blockchain explorers like BscScan and Etherscan.
10% Fee Allocation
A consistent 10% of all spot trading fees is directed to SAFU, ensuring the fund grows proportionally with Binance's volume.
Fun fact: SAFU was born from the viral "Funds Are SAFU" meme created by YouTuber Bizonacci in 2018. Binance embraced the meme and turned it into a billion-dollar protection fund -- one of the rare cases where internet culture directly shaped financial infrastructure.
The "Funds Are SAFU" Meme Origin
On July 7, 2018, Binance CEO Changpeng Zhao (CZ) tweeted "Funds are safe" during a routine system maintenance that had users worried. This brief message, intended to calm nerves, sparked one of crypto's most enduring memes.
Shortly after, YouTuber Bizonacci created a viral parody video featuring a distorted version of CZ's voice declaring "Funds are SAFU" -- a deliberate mispronunciation that instantly became iconic. The video spread like wildfire across Crypto Twitter, Reddit, and Telegram.
Rather than dismissing the meme, Binance embraced it and created the SAFU backronym: Secure Asset Fund for Users. What started as internet humor became the foundation for a $1 billion user protection initiative -- arguably the most successful meme-to-product conversion in financial history.

SAFU Fund Composition: Historical Evolution
The SAFU fund's composition has evolved significantly since its founding. What started as a multi-asset fund has undergone several strategic shifts, culminating in a bold move to convert entirely to Bitcoin in early 2026.
| Phase | Period | Composition |
|---|---|---|
| Phase 1 | 2018 - 2023 | BTC, BNB, USDT, TUSD, BUSD |
| Phase 2 | March 2023 | BUSD replaced with USDT/TUSD |
| Phase 3 | April 2024 | Full conversion to USDC |
| Phase 4 | Jan - Feb 2026 | Converting USDC to Bitcoin |
Current status: 6,230 BTC accumulated (~$402-434M at current prices), approximately 40% of the $1B conversion complete.
SAFU Wallet Addresses (On-Chain Verification)
Binance publishes SAFU wallet addresses so anyone can independently verify the fund's holdings. These addresses are trackable on BscScan, Etherscan, and Arkham Intelligence. Transaction IDs from major conversions are also published on X (formerly Twitter).

SAFU has been activated multiple times to reimburse users following security incidents. Here are the documented cases where the fund was used to cover user losses:
| Incident | Date | Amount | Outcome |
|---|---|---|---|
| Binance Hot Wallet Hack | May 2019 | $40.7M (7,000 BTC) | Full user reimbursement |
| BNB Chain Bridge Hack | Oct 2022 | ~$100M mitigated | Chain halted, SAFU topped up to $1B |
| Trust Wallet Chrome Hack | Dec 2025 | $7M | Full reimbursement via SAFU |
Total documented SAFU payouts: $47.7M+. In every recorded case, affected users were fully reimbursed without bearing any losses.
How SAFU Works: Technical Mechanism
The SAFU fund operates through a systematic process of funding, storage, and activation. Understanding how it works helps you evaluate the actual level of protection it provides.
What SAFU Covers
- Security breaches and hacking incidents
- Critical system failures causing user losses
- Exploits in Binance-affiliated wallets (e.g., Trust Wallet)
What SAFU Does NOT Cover
- Market losses from trading or price drops
- Losses due to user error (wrong address, etc.)
- Phishing or social engineering scams
- Insolvency or bankruptcy scenarios
Key Operational Details
SAFU vs Other Exchange Insurance Funds
Several major exchanges have launched their own insurance or protection funds. Here's how Binance SAFU stacks up against the competition:
| Feature | Binance SAFU | Bitget Protection | Bybit Insurance | OKX Risk Shield |
|---|---|---|---|---|
| Fund Size | $1B | $716M+ | Undisclosed | Not disclosed |
| Founded | 2018 | 2022 | N/A | N/A |
| Composition | BTC (converting) | BTC + USDT | Per-contract | N/A |
| Verified | On-chain | On-chain | Partial | PoR reports |
| User Coverage | 300M+ | 100M+ | 50M+ | 50M+ |
Latest News: The $1B Bitcoin Conversion (Feb 2026)
In late January 2026, Binance announced it would convert the entire $1 billion SAFU fund from USDC to Bitcoin within 30 days. This is one of the largest corporate Bitcoin acquisitions in crypto history. Here is the progress so far:
Conversion Announced
Binance announces plan to convert $1B USDC to BTC within 30 days
First Purchase
First tranche purchased: 1,315 BTC (~$100M)
Second Purchase
Second tranche purchased: 1,315 BTC (~$100.42M)
Third Purchase
Third tranche purchased: 3,600 BTC (~$250M)
Conversion Progress
Context: This move followed the October 2025 $19B liquidation event that shook crypto markets. CZ stated that holding SAFU in Bitcoin better aligns the fund with the long-term interests of Binance's user base.
Proof of Reserves & Transparency
In the wake of the FTX collapse in late 2022, Binance launched its Proof of Reserves (PoR) system to demonstrate that user funds are fully backed. This system works alongside SAFU to provide multiple layers of transparency.
Total Assets Verified
$162.8B
Asset Categories
45+
Verification Technology
Merkle Tree + zk-SNARK
Code Status
Open-sourced
Binance uses Merkle tree proofs combined with zk-SNARK (zero-knowledge succinct non-interactive argument of knowledge) technology. This allows users to verify that their individual account balances are included in the total reserves without revealing anyone's specific balance. The verification code has been open-sourced so independent auditors and developers can review it.
Controversies & Criticisms
While SAFU is widely seen as a positive initiative, it is not without criticism. A balanced evaluation requires understanding its limitations:
Not True Insurance
Unlike regulated insurance products (e.g., FDIC in the US), SAFU carries no legal guarantee. Payouts are entirely at Binance's discretion, and there is no independent regulatory body overseeing the fund.
Bitcoin Conversion Volatility Risk
Converting from USDC (stable) to BTC (volatile) means the fund's value could drop significantly during a bear market. A 50% BTC crash would reduce the effective protection to $500M.
October 2025 Liquidation Controversy
The $19 billion liquidation event in October 2025 raised questions about Binance's risk management. While SAFU was not depleted, the scale of liquidations tested user confidence.
Discretionary Payouts
Binance alone decides when and how SAFU is deployed. There are no published criteria or thresholds that automatically trigger fund activation.
Insolvency FUD (Feb 2026)
In early February 2026, unfounded rumors circulated about Binance's solvency. While quickly debunked by Proof of Reserves data, the incident highlighted that SAFU does not address insolvency risk.

How to Protect Your Crypto on Binance
While SAFU provides a safety net, you should also take proactive steps to secure your own assets. Here are 5 essential security practices:
Enable 2FA and Anti-Phishing Code
Activate two-factor authentication (Google Authenticator or hardware key) and set an anti-phishing code so you can identify genuine Binance emails.
Use Cold Wallet for Long-Term Holdings
Keep long-term holdings on a hardware wallet like Ledger or Trezor. Only keep funds on the exchange that you actively trade with.
Don't Keep All Funds on One Exchange
Diversify across multiple reputable exchanges and cold storage. No single exchange, regardless of its insurance fund, should hold 100% of your portfolio.
Monitor Proof of Reserves Regularly
Check Binance's Proof of Reserves page periodically to verify that user assets are fully collateralized. Look for consistent 1:1+ backing ratios.
Sign Up with Referral for Fee Discount
Use referral code TRADEOFF20 when creating your Binance account to get a permanent 20% discount on trading fees. Lower fees mean more capital preserved in your account.

Risk Warning
Cryptocurrency trading and investing carry significant financial risk. The SAFU fund is not a guaranteed insurance product and does not protect against market losses, user errors, or exchange insolvency. Past payouts do not guarantee future coverage. Never invest more than you can afford to lose. Always do your own research (DYOR) before making any financial decisions.
