In 2022, Web3 globally lost $2.3 billion to different frauds and vulnerabilities, with 377 incidents registered. Cryptocurrency exit scams made up 97.7% of tokens offered on the decentralized crypto market Uniswap. If you invest in cryptocurrency, and especially if you like to buy into smaller projects, understanding this type of scam is a must.

What Is an Exit Scam?

An exit scam is a deceptive strategy used by unscrupulous cryptocurrency promoters who set up a phony cryptocurrency company and then disappear with investors' funds after they have amassed a large enough sum. The rug pull is a popular sort of exit scam in which scammers advertise a project and then abandon it after filling their wallets.

Unlike in centralized financial systems with central bank control, the decentralized, anonymous structure of digital currencies makes it difficult to track down fraudsters who defraud investors. Due to this, many gullible and uninformed investors have been duped out of their money through exit scams.

DeFi Exit Scams

DefI Exit scams are most common in tokens on decentralized exchanges (DEXs) that rely on a liquidity pool held on the DEX. Scammers that masquerade as developers typically develop and launch a promising Defi project that attracts a big number of users, they then raise funds from various investors and after that the firm may or may not operate for a period of time before the promoters vanish, either by fleeing with the ICO capital, removing the liquidity pool, or selling their own coin, leaving investors in the dark.

Decentralized finance-related projects published on decentralized exchanges are extremely dangerous due to the abundance of exit scams in the field. Defi exit scams have occurred on several occasions, even with currencies listed on prominent centralized exchanges.

Modus Operandi

  1. Promoters launch a new cryptocurrency platform with exciting and promising investment concepts. It then starts to seek funds from investors via an ICO. The company may or may not operate. The promoters then vanish with the ICO funds, leaving the investors without anything.
  2. Another sort of exit scam involves scammers operating a Ponzi scheme under the cover of a cryptocurrency exchange or investment firm. They keep the project going until the truth is revealed, at which time they vanish with all of the investment funds.
  3. In certain situations, they may even manage the project for a period of time, pushing and boosting prices before trading their tokens and disappearing. In any case, after they've made their money, they're out the door, which is why these schemes are regarded as exit scams.

Closing Thoughts:

Despite the numerous frauds, the blockchain ecosystem is still producing outstanding businesses that tick all the right boxes. Aptos Network is a good example.

Aptos, a Layer 1 POS network with over 100 apps developed on it, was established by Mo Shaikh and Avery Ching with the goal of creating the most secure and scalable blockchain possible. After a series of testnets were released at the beginning of the year, the mainnet went live on October 19, 2022.

For application development, the Aptos blockchain employs the Move programming language and the Move VM, both of which were built and optimized for blockchain use cases. The language was created with scalability and security in mind.

Aptos blockchain is a Proof of Stake network with low latency Byzantine Fault Tolerant (BFT) technology. When a node or set of nodes behaves maliciously, the BFT mechanism prevents network failure.

Pontem is developing the next generation of dApps with simplified experiences supported by Aptos and Move in order to accelerate global adoption for both customers and institutions.

Pontem also created a fork of the Diem Move Virtual Machine that is easily deployable to other current chains such as Polkadot, Avalanche,  Cosmos, and others.
