Blockchain Security Consulting

Blockchain's security story is genuinely different from a traditional application's. The ledger itself is hard to tamper with, but almost everything that goes wrong in practice happens around the edges: smart contracts with logic bugs, private keys that get mishandled, and the bridges and off-chain components that connect a blockchain system to the regular internet.

If you're building or operating something on-chain, the honest starting question is: where's the actual trust boundary, and what happens if it fails? A smart contract bug that lets someone drain funds, a compromised signing key, a bridge contract with an unchecked assumption — these are the incidents that actually make headlines, far more often than the underlying consensus mechanism being broken.

What a review actually covers

For smart contracts, that means reading the code for the well-known failure classes — reentrancy, integer overflow in older Solidity, access control gaps, oracle manipulation — and thinking through what happens under adversarial economic incentive, not just adversarial code. For key management, it means understanding how private keys are generated, stored, and used for signing, and whether a single compromised machine or person can move funds.

For anything with an off-chain component — a bridge, an oracle, an API that feeds data on-chain — that's often where the actual attack surface lives, and it deserves the same scrutiny as any other piece of software, because that's exactly what it is.

Being direct about this

I'll tell you plainly if something looks fine and if something looks genuinely risky. This space has a lot of incentive to reassure clients that everything's secure; I'd rather you hear the real answer from me before you hear it from an attacker.
