Smart contracts revolutionized the blockchain industry by bringing a significant shift in how agreements are conceptualized and carried out. Ethereum introduced smart contracts to ensure the creation of programs on blockchain networks, signaling the start of smart contracts in blockchain application development services. Smart contracts have facilitated the creation of dApps for various purposes, broadening the application of blockchain technology beyond decentralized financial dealings.

In recent years, many platforms with unique features and abilities have emerged to support smart contracts on the blockchain. The connectivity between the blockchain and smart contracts has helped to promote creativity in the web3 and blockchain sectors. Let's delve deeper into how smart contracts affect blockchain app development services.

## The Definition and Source of Smart Contracts

Smart contracts are agreements that automatically execute when conditions are met, with contract terms embedded in code. For transparency and immutability, the code is stored and copied across a decentralized blockchain network. The contract automatically enforces predefined conditions to enable secure and trustless transactions. Due to advancements in blockchain technology, smart contracts have made significant progress since computer scientist Nick Szabo first introduced the concept in the 1990s.

Nick Szabo originally introduced the concept of self-executing contracts written in computer code in his revolutionary publication from 1994. This is the birthplace of smart contracts. Smart contracts only gained popularity once blockchain technology became widespread, especially after Vitalik Buterin introduced Ethereum in 2015. Ethereum's programmable blockchain opened the door to a fresh era of digital agreements and automated transactions, allowing developers to create DApps and utilize smart contracts.\

## How Do Smart Contracts Work?

Essentially, smart contracts are the digital versions of traditional legal contracts that operate automatically. Software code is utilized to automate and execute the specified terms and conditions of an agreement. These agreements are secure since they are coded and stored on a transparent, secure, decentralized blockchain network.

Smart contracts are autonomous programs that execute actions once specific conditions are met. Examine a blockchain application designed for the supply chain. A smart contract can automatically trigger payment after receiving a delivery confirmation, eliminating the necessity for human intervention or third-party involvement.

It is fascinating to consider that the use of smart contracts reduces the necessity for traditional intermediaries such as banks or lawyers, thus reducing the risks of fraud, errors, or non-adherence. The popularity of these intelligent contracts grew mostly due to Ethereum's blockchain technology, offering a robust base for their development and application in sectors like supply chain management, real estate, and finance.

The consistent duplication of smart contracts on different nodes in a blockchain network, along with their predictable behavior, guarantees clear and coordinated execution of agreements for all participants. Despite the numerous advantages, one must remember that thorough testing and [auditing](https://www.cyberscope.io/smart-contract-audit) of smart contract code is essential before deployment to prevent any potential issues or vulnerabilities due to their immutable nature.

## What is Drainer-as-a-Service (DaaS)?

A crypto drainer is a phishing tool crafted specifically for the web3 ecosystem. Rather than stealing passwords and usernames, drainer operators typically pretend to be web3 projects, convincing victims to link their crypto wallets to the drainer and authorize transactions that give the operator access to the wallet's funds. If they succeed, drainers can immediately take users' money directly. Drain operators frequently advertise their fraudulent web3 platforms in Discord groups and on hacked social media profiles.

## An overview of DaaS and Crypto Drainers

A crypto drainer is a harmful tool or script created to move cryptocurrency from a victim's wallet to one controlled by an attacker. Drainers began targeting MetaMask in approximately 2021, when they were publicly advertised in secretive online platforms and markets.

However, there are various forms in which drainers and drainer-style attacks can manifest. Malicious smart contracts could have concealed features that activate unauthorized transfers. Alternative types of drains could utilise NFTs or token-triggered schemes to create counterfeit assets, enabling the covert and unauthorized exchange of cryptocurrencies.

Crypto drainers are frequently accessed via a Drainer-as-a-Service approach, where DaaS providers supply cybercriminals with software and assistance in exchange for a portion of the looted money. Some common services provided by a contemporary DaaS platform are

* Turnkey crypto-draining scripts
* Customizable smart contracts
* Phishing kits and social engineering services
* Premium OPSEC or security and anonymity services
* Integration assistance and mixing/obfuscation
* Ongoing updates, maintenance and technical support.

Cryptocurrency draining scripts that are turnkey or ready-to-use are utilized to automate the process of draining cryptocurrency from specific wallets. They are designed to be easy to comprehend and implement, without the need for much prior experience.

Quick link:[What is Proof of History and How Does It Work?](https://www.cyberscope.io/blog/what-is-proof-of-history-and-how-does-it-work)



## How to Avoid Crypto Drainers

As cyber criminals using crypto-draining techniques become more advanced, it will be more crucial for both web3 projects and users to integrate multiple security measures to guard against this harmful behavior. Wallet Guard and other Web3 security features can detect scam websites and pages, as well as evaluate potential security threats linked to digital currency wallets.

To avoid being exposed to drainers, individuals can store significant amounts of assets in an offline wallet and only move funds to a hot wallet as necessary. Participants in the ecosystem need to be cautious of links shared in chat rooms or on social media that might not be connected to the official account of a project.

In case a private wallet user must connect to a web3 site they are not familiar with, they can generate a temporary wallet without any assets and link it to the site. In case a drainer steals a victim's assets, the victim has the option to void any unfinished transactions.

## Who are the Targets of DaaS Attacks?

DaaS attacks can target a wide range of victims, but certain groups are more vulnerable:

* Individuals: People with limited cybersecurity awareness or weak security practices are prime targets for credential theft and subsequent account takeovers.
* Small Businesses: Small businesses often lack robust cybersecurity measures, making them susceptible to web injection attacks that target their online payment systems.
