An unspent transaction output (UTXO) is the amount of digital currency that remains after a cryptocurrency transaction. We can think of it as the change we receive after buying an item. Please read below.

MEV occurs when block producers in a blockchain (miners, validators) are able to extract value by reordering, including or excluding transactions within a block. They can determine order of transactions processed & exploit power to their advantage.

In 2022, according to blockchain analytics firm, Chainalysis, out of $3.1 billion stolen from DeFi protocols, 64% of these funds were lost to exploits of bridging protocols.

For better bridging solution, LayerZero was born. Stargate, Synapse & Composable uses LayerZero Protocol.

ERC20 tokens return a boolean value upon executing transfer/transferFrom functions & revert transaction in case of failure. However, in USDT the return value of the transfer/transferFrom function is always false leading to DOS attack. Please read below.

Weird ERC20 Tokens

ERC20 specification is so loosely defined that they are routinely violated by token developers.

Please check below repo where the tokens are based on real tokens, many of which have been used to exploit smart contracts in the past.

To make sure the price of perpetual contracts does not diverge too much from the price of their underlying assets, perpetual contracts use a funding rate.

[Nupur Panjiar @NPanjiar]

Perpetual Futures allows for gaining exposure to a price of a particular financial instrument without holding the underlying asset. This can be useful for multiple purposes including price speculation, hedging or arbitrage. Please read below.

In standard futures, the settlement date is quite important as it allows the price of future contracts to converge with the actual price of the underlying asset as the settlement date approaches.

What is Hedging in crypto❓

Hedging provides traders a form of insurance when prices move in an unfavorable direction. It involves the use of financial instruments - derivatives. Two of the common derivatives are options and futures.

Liquidity refers to how easily users can trade one cryptocurrency for another on an exchange. If a token lacks liquidity, holders may not be able to sell their tokens when they wish.

An important point to consider before purchasing crypto tokens.
