EkoLance is launching a 10-week course for people seeking a career in the blockchain ecosystem as a smart contract auditor.

The official start date of the course is the 5th of September, 2023. The sessions take place every Tuesday at 6PM CET online via Zoom.

Why this training is important?

A smart contract audit is an assessment of the code and logic of a smart contract to identify potential errors, vulnerabilities, or security weaknesses that could result in unintended behavior or financial loss.


There have been several high-profile hacks of smart contracts due to weak audits or lack of auditing altogether. Some examples include:

  1. The DAO hack: In 2016, a hacker exploited a vulnerability in the code of The DAO, a decentralized autonomous organization built on Ethereum, and stole over 3.6 million ether (worth around $50 million at the time). The vulnerability was caused by a mistake in the smart contract code that allowed the hacker to repeatedly withdraw funds from the organization.

  2. Parity Wallet hack: In 2017, a vulnerability in a smart contract of the Parity Wallet library contract led to the theft of over 153,000 ether (worth around $30 million at the time) from several Ethereum wallets. The vulnerability was caused by a mistake in the smart contract code that allowed the hacker to gain control of the library contract and steal the funds.

  3. bZx hack: In 2020, a hacker exploited two separate vulnerabilities in the code of the bZx decentralized finance (DeFi) platform, which allowed the hacker to steal over $8 million worth of cryptocurrency.

  4. Harvest Finance: In 2020, a hacker exploited a vulnerability in the smart contract code of the Harvest Finance decentralized finance (DeFi) platform, which allowed them to steal $24 million worth of cryptocurrency.


These and other high-profile smart contract hacks have highlighted the importance of performing thorough and regular smart contract audits to identify and fix vulnerabilities before they can be exploited by attackers.

Due to the danger of smart audit hacks and vulnerabilities in smart contracts, which can lead to huge financial losses, the profession of a smart contract auditor has become extremely important and demanded.

A Smart Contract Audit Training is important because it teaches individuals how to perform the assesment of smart contracts in a systematic and thorough manner, so they can identify and address any issues before the contract is deployed on a blockchain network. Additionally the Smart Contract Audit Training covers understanding the mechanism and the code of a smart contract which help the auditor to identify possible risks which may lead to financial loss.

EkoLance understands the importance of making blockchain products more secure and is providing structured web3 training for web3 developers, who want to upskill and become smart contract auditors.
