Cryptocurrency derivatives exchange Bitunix has expanded its dedicated Care Fund from $30 million to $50 million USDC, enhancing user asset protection across its trading platform. The capital increase provides a fully backed reserve to cushion against unexpected operational or security emergencies.
- Bitunix increased its Care Fund reserve to $50 million USDC, expanding from its initial $30 million launch in 2025.
- The updated balance fully covers the total value of assets held in the exchange's internet-connected hot wallets.
- The reserve address is now publicly available for independent verification on Etherscan.
- Custody infrastructure relies on third-party providers Fireblocks and Cobo using multi-party computation (MPC) technology.
On-Chain Visibility and Hot Wallet Protection
By publishing the official Etherscan address for the $50 million USDC fund, Bitunix allows public oversight of its reserve balance. According to company disclosures, the $50 million allocation is sufficient to match the total market value of funds stored in its hot wallets, which process live user transactions and withdrawals.
The fund specifically targets extraordinary incidents that require an exchange-level resolution, excluding routine market outcomes or standard trading losses. Potential claims undergo individual reviews, account verifications, and factual investigations before any compensation is dispersed. This commitment to operational verifiability mirrors broader market trends where platforms maintain transparent Proof of Reserves data to build user trust.
MPC Custody and Multi-Layer Security Architecture
Rather than constructing wallet management tools internally, Bitunix partners with institutional custody specialists Fireblocks and Cobo. Both custodians implement multi-party computation (MPC), splitting private key shares so no single entity can unilaterally transfer funds. A substantial portion of customer deposits also remains in offline cold storage.
Serving over 5 million users across more than 150 countries, Bitunix integrates the Care Fund alongside account security controls, penetration tests, user insurance, and Proof of Reserves (PoR). Its trading ecosystem also features Fixed Risk controls, TradingView-powered chart suites, indicator alerts, and cloud-synced templates.
Why It Matters
As trading activity expands across global derivatives venues, dedicated reserve funds offer a critical safety cushion against major smart contract or wallet vulnerabilities. By explicitly capping hot wallet exposure with a $50 million USDC liquid balance, Bitunix mitigates systemic insolvency risks during unexpected crisis events. Public on-chain verification on Etherscan also establishes a transparent standard for custodial safety that competitors may be pushed to adopt.
