VaultMind is now CoinSec. We've taken a new name, one that better reflects what we do and where we're heading: securing the code the on-chain economy runs on.
Every computing shift required a new approach to security
Every computing shift has moved the attack surface and needed a new kind of security to cover it. The PC put the risk on the device, and antivirus was the answer. Networks put it at the boundary between companies, and the firewall was the answer. The cloud put it in infrastructure companies no longer owned, and cloud security was the answer. Each time, a new company grew up around that answer: McAfee and Symantec, Check Point, CrowdStrike and Wiz.
Blockchains are the next computing shift
That shift is happening again, and this time the computer is a blockchain: a "computer in the sky" that nobody owns and everyone shares.
Financial institutions have recognized that potential and are using it to build new payment rails: money that settles cheaper and faster, anywhere, around the clock, with the rules written in programs called smart contracts. Stablecoins moved $33 trillion on-chain in 2025, more than Visa and Mastercard combined. JPMorgan's deposit token went live on a public blockchain in November 2025. Twenty-one banks, including Goldman Sachs, Citi and Bank of America, are building a joint dollar stablecoin for 2027.
With this shift, the attack surface is moving to a new place: smart contracts. And a vulnerability in a smart contract is fatal in a way it isn't elsewhere. Exploiting it takes a single transaction: by the time anyone sees it, the money is gone. There is no fraud desk, no chargeback, no window to respond. Of the 207 crypto hacks recorded in the first half of 2026, 125 exploited a smart contract, and the fastest exploits now hit a contract within minutes of its launch.
Blockchains need a new approach to security
Today, smart contracts are secured by manual audits: a team of experts reads the code once, before launch, and lists what it finds. Everything shipped after that goes unchecked.
Until recently, that was good enough, because finding an exploit took a skilled person weeks. The scarcity of people who could do it was the real defense. AI changed that.
In December 2025, Anthropic tested AI agents on 405 smart contracts that had been hacked in the real world. The agents produced a working attack for half of them, and when pointed at newly launched contracts with no known vulnerabilities, they found two new ones, at about a dollar per attempt.
The frontier labs can gate the cyber capabilities of their most capable models. But the same capability now sits in open-weight models anyone can download, fine-tune and run without safeguards. Attackers run agents that hunt every new smart contract around the clock.
An audit that happens once cannot keep up with an attacker that never stops. Security has to be continuous, running every time the smart contract code changes, and it has to happen before the code goes live, when a vulnerability can still be fixed. That is what we are building at CoinSec.
What CoinSec does
CoinSec takes a company's smart contracts, makes a private copy of the live blockchain and tries to drain them there, the way an adversary would. And like AlphaGo, it learns from every attack it runs, the ones that work and the ones that fail, so it keeps finding attacks no human auditor has seen. It then suggests the patch and re-runs the attack to show the hole is closed. It can run once before a new launch, on every change a company ships, or as a dedicated attacker trained on one protocol.
