Industry leading security & velocity.

Bullish’s best-in-class crypto custody architecture maximizes the security of your assets by mitigating risks, without sacrificing the speed of your deposits or withdrawals.

Multi-layer protection.

Bullish combines industry leading technology and operational procedures developed by security and custody experts to ensure customers’ digital assets remain secure.

Hardware safeguards.

Cold custody. A majority of assets are stored offline in cold wallets.

Offline cold key storage. All private keys are isolated from one another and stored offline or in secure modules on shielded cloud servers.

Software safeguards.

Signed & attested systems. All custody software components and operating systems are cryptographically signed.

Multi-signature wallets. Signing processes are distributed across independent actors for collusion resistance.

Blockchain security. Blockchain-based oracles verify provenance of custody actions and stop man-in-the-middle attacks.

Operational safeguards.

Policies. Our protocols govern which crypto wallets interact with one another, what keys are required to sign a transaction, and the limits to transaction size and velocity.

Disaster recovery. Our procedures include globally distributed backup keys.

Faster on, faster off.

Bullish also gives you the security of knowing you can quickly move digital assets on or off the exchange when you want, regardless of market conditions.

Segregation of assets.

Customer funds are always separated from company assets, so co-mingling on any account or blockchain address never occurs.

Wallet architecture


Speed without sacrificing security.

Bullish uses cold, warm, and hot wallets. Our whitelisting protocol ensures maximum protection for your digital assets, with all transfers carefully monitored to minimize 
any risk of loss or theft.

Speed without sacrificing security.

Bullish’s AML and Transaction Monitoring systems flag suspicious or fraudulent activities and move these assets into an AML wallet. Allowing us to segregate these funds immediately and protect our customers.
