(Cryptographic) Tokens

Representations of the virtual currency stand on a motherboard in this picture illustration taken May 20, Here is what we know so far about the heist. A lesser-known name in the world of crypto, Poly Network is a decentralized finance DeFi platform that facilitates peer-to-peer transactions with a focus on allowing users to transfer or swap tokens across different blockchains.

For example, a customer could use Poly Network to transfer tokens such as bitcoin from the Ethereum blockchain to the Binance Smart Chain. Poly Network was founded by Chinese entrepreneur Da Hongfei, who is currently chief executive of Neo, a blockchain platform.

According to Neo's website, Poly Network was launched in August last year as a collaboration between Neo, crypto trading platform Switcheo and blockchain company Ontology. Tokens are swapped between the blockchains using a smart contract which contains instructions on when to release the assets to the counterparties. One of the smart contracts that Poly Network uses to transfer tokens between blockchains maintains large amounts of liquidity to allow users to efficiently swap tokens, according to crypto intelligence firm CipherTrace.

Poly Network tweeted on Tuesday that a preliminary investigation found the hackers exploited a vulnerability in this smart contract.

According to an analysis of the transactions tweeted by Kelvin Fichter, an Ethereum programmer, the hackers appeared to override the contract instructions for each of the three blockchains and diverted the funds to three wallet addresses, digital locations for storing tokens. These were later traced and published by Poly Network. The attackers stole funds in more than 12 different cryptocurrencies, including ether and a type of bitcoin, according to blockchain forensics company Chainalysis.

A person claiming to have perpetrated the hack said they had spotted a "bug," without specifying, and that they wanted to "expose the vulnerability" before others could exploit it, according to digital messages posted on the Ethereum network published by Chainalysis.

Reuters could not verify the authenticity of the messages. Coindesk reported on Tuesday that the hackers had initially tried to transfer some of the assets from one of the three wallets into liquidity pool Curve. But early Wednesday the hackers started transferring assets back to Poly Network into a wallet which both parties controlled.

It added that it was still communicating with the hackers, referring to them as "Mr White Hat" - an ethical hacker who generally works to expose vulnerabilities so they can be fixed. The hacker or hackers have not yet been identified. Cryptocurrency security firm SlowMist said on its website that it has identified the attacker's mailbox, internet protocol address, and device fingerprints, but the company has not yet named any individuals.

SlowMist said the heist was "likely to be a long-planned, organized and prepared attack. Despite the purported hacker posing as a so-called "white hat", an ethical hacker who had "always" planned to give the money back, according to the messages published by Chainalysis, some crypto experts are skeptical. Gurvais Grigg, chief technology officer at Chainalysis and former FBI veteran, said on Wednesday that it was unlikely that white hat hackers would steal such a large sum and that they may have returned the money due to the difficulties of laundering it.

ICOs are another form of cryptocurrency that businesses use in order to raise capital. It is a means of crowdfunding through the creation and sale of a digital token to fund project development. This unique token functions like a unit of currency that gives investors access to certain features of a project run by the issuing company. These tokens are unique because they help fund open-source software projects that would otherwise be tough to finance with traditional structures. This information will include, but is not limited to: what the project is about; what objectives the project will aim to fulfill upon completion; how much money is necessary to undertake the venture; how many virtual tokens the issuers will keep for themselves; what type of currency is accepted; how long the ICO campaign will run for; and who the team is behind the white paper. The company issuing the ICO prepares the white paper prior to launching the currency.
