Cause of losing money when farming

Indirect causes

Due to Smart Contract errors, the intervention of changing data input from Oracle causes farming protocols to be hacked, causing damage to the platform. Some recent “explosions” such as Harvest Finance, Origin Protocol, … are certainly no longer strangers to brothers, causing indirect damage to assets on farming platforms. If the platform is reputable, the user will be compensated, otherwise the brothers will likely lose crypto assets.

Of course, this incident was completely force majeure and no one expected this situation to happen.

Below are some projects that yield farming, lending, and staking projects that have had hacking problems recently with Harvest Finance, which have suffered the heaviest losses with 33.8 million USD.

Direct cause

First of all, you should understand the generalization of farming, this is the activity of providing liquidity to the pool of a protocol or platform to try to make profits from crypto assets.

In order for farming activities to take place, you need to connect your personal wallet with the farming platform. Approve operation is the step you must go through if you want to swap or farming.

Approve is an approval for owners of Smart Contract / farming platform to have the right to connect, access and have full control over your funds to swap or provide liquidity to the pool.

Suppose, you want to farm 1000 ABC Token into pool X of platform Z, to provide liquidity to pool X, you need to connect your personal wallet containing 1000 ABC Token and click. Approve so that the platform’s smart contract connects to the wallet.

After clicking Approve, the Z platform has full right to use the approved sibling quota of 1000 ABC Token.

  • Case 1: Good, reliable project → Project to bring your money and provide it to the pool for farming.
  • Case 2: Project scam, scam → Taking advantage of the Approve operation to swap your coin to another coin → Withdraw the pool’s liquidity and disappear → You lose money but don’t know the reason .

Approve actions also include the Unlimited Approve feature. Unlimited Approve is a feature that allows the platform, smart contract to fully process the amount of money stored in your wallet with a maximum limit.

  • Benefit: Save fees for transactions, fast manipulation, no need to click approve for the next transaction and farming time. Approve has no time limit.
  • Disadvantage: Risks directly affect the assets, giving 100% rights to contract owners.

How safe farming and limit the risk of wallet hack?

Store assets in many different wallets

You should store assets in many different wallets and especially dedicate one wallet just to store the property and not interact with any other smart contract or platform.

Need a wallet specializing in farming, if you want to farm any coin, just transfer money from the exchange or another wallet into a farming wallet. This helps you to limit the risk of losing assets when farming. In the case of the farm brothers having to cheat the project, they only lose the money in the wallet, not any other money.

You see many organizations introducing farming platforms with high annual interest rates (APY) without any unconfirmed proof of pouring money into the farm, it is very likely that your money will not fly. .

Please consider, carefully consider the project on reliability (audited or not, of course, audited projects are still at risk of hacking, but when there is confirmation, you also have more confidence), Look at the project team, technologies, roadmap and development ways to evaluate the project before putting money into farming.

Approve after farming times

After each farming review, immediately visit to cancel the approval rights for platforms to avoid checking your wallet and realizing your money was lost on a fine day.
