In the dynamic and constantly evolving domain of blockchain and smart contracts, the paramount concern is the security of investments. 2023 has been a year marked by significant vulnerabilities, with over $300 million lost in Q2 and more than $320 million in Q1 to blockchain-related hacks and exploits. Ethereum blockchain hacks alone led to losses of $221 million in the first quarter, highlighting the severity of such security breaches. The total losses due to exploits, scams, and hacks in the blockchain sphere have alarmingly reached approximately $1.34 billion by September 2023. This underscores the critical need for robust security solutions like Hackless Sentinel, which offers a shield against the risks associated with staking funds or investing in smart contract-based projects, particularly those susceptible to malicious activities or rug pulls. Let’s delve into the most prevalent scenarios where Hackless Sentinel can provide indispensable protection in this high-risk landscape.

The Scenario 1: A Risky Smart Contract

You’ve plunged into the digital finance world by staking funds in “FakeStaking”, a smart contract with a twist — a “claimByOwner” function that could let the contract owners whisk away your investment. Here’s where Hackless Sentinel comes to your rescue, turning your worries into a tale of smart security!

Step 1: Gear Up with Hackless Sentinel

First, head over to the Hackless Sentinel website. Imagine this as entering a digital fortress where your crypto assets are about to get some serious armor. Once you’re logged in, it’s time to set the stage for guarding your stake.

Step 2: Setting the Trap for “claimByOwner”

Now, let’s get down to the nitty-gritty:

  • Trigger Setup: In the Sentinel’s control room, you’ll create a new request. Think of this as laying a digital tripwire. You’ll enter the “claimByOwner” function as your trigger. If the contract owners try to pull a fast one, Hackless Sentinel will know instantly.
  • Your Secret Move: You’re not just going to wait around. You set up a counter-move — a transaction that will fire back, safeguarding your staked funds if the owners try anything funny.

Step 3: Customize Your Counter-Attack

Here’s where you need to become a crypto strategist:

  • Crafting Your Response: Using protocol, you create a transaction that could save your funds in a pinch. This is your secret weapon, hidden in the hex data — a code that’s ready to spring into action.
  • Fine-Tuning the Details: You’ll set a gas limit and maybe bump up the gas price a bit. Why? To ensure your transaction is quick on the draw, faster than the contract owners’ sneaky move.

Step 4: Lock and Load

Before you bring your plan to life:

  • Double-Check: Eyeball everything in your request preview. Every detail matters here.
  • Seal the Deal: Sign off on the transaction using MetaMask. This is like putting your digital signature on your master plan.

Step 5: Watch Your Plan Unfold

After hitting “Create Request,” your setup is complete. Hackless Sentinel now stands guard, watching for any move from the “FakeStaking” owners. If they trigger the “claimByOwner” function, your counter-transaction swoops in to save your stake.

Here is the example of the transaction sequence in the same block:

Claim — Position 1, ClaimByOwner — Position 105

After transaction processing your request will change status to completed.

The Outcome: Safeguarding Your Stake

In the complex environment of DEX pools, characterized by rapid and unpredictable shifts, a new protective solution offers technical sophistication combined with ease of use. This upcoming product provides a swift and efficient mechanism to safeguard against rug pulls. With just two clicks, it initiates a pre-set transaction protocol, strategically transferring assets to a secure state, effectively mitigating the risk of malicious withdrawal attempts. Detailed technical specifications and operational mechanisms of this innovative solution will be outlined in our upcoming announcement, promising a blend of advanced security and user-friendly operation.
