An Automated Market Maker (AMM) is part of a decentralized exchange (DEX) and automatically gives the trader a quote for price between two assets, thus allowing direct automated settlement of the transaction.
If a user wants to move funds from one blockchain to another, so say from Ethereum to Solana, or just want to make use of L2 scaling solutions on a sidechain of Ethereum, a bridge helps to transfer these funds.
A Call option gives the right to buy an underlying asset for a specific price within a specific period of time.
The collateralization of a loan gives the lender some level of reassurance against the default risk of the borrower. Collateralization is normally done by locking some valuable asset as a security to the loan, that is then seized by the lender and sold to offset the loss from the defaulted loan.
Correlation is a statistical relationship between two random variables.
As a blockchain works like a decentralized database, understanding how data can be sourced and how you can deal with data issues is crucial for any kind of understanding, analyzing & modeling metrics and tools. Please look here for more details on the general purpose of Data sourcing as well as Market Data and Account Level Data.
Short for Decentralized Finance, thus the offering of financial instruments, products and services peer-to-peer via a distributed ledger technology (like the Ethereum blockchain) without a centralized third party like a bank or other institution.
Short for Discounted-Cash Flow, a common methodology to value an asset by discounting the future cash flows and thus calculating the fair present value of the asset.
The Efficient Frontier describes a concept of the Modern Portfolio Theory to optimize a portfolio (so a number of different assets) for the lowest level of risk with a given return target. It reduces the variability of the portfolio return and hence increases the Sharpe ratio. More details on the Efficient Frontier can be found here.
Gas refers to the unit that measures the amount of computational effort required to execute specific operations on the Ethereum network. Gas fees are the reward given to miners for putting transactions in the blockchain or executing them. Learn more here.
In distributed ledger systems like blockchains, L1 refers to Layer 1, the so-called base layer of the blockchain where all transactions are finally settled.
L2 refers to a third-party integration (like a side-chain) that processes transactions and bundles them for final settlement on the underlying L1 blockchain. L2 solutions abstract the majority of the processing in order to improve scalability and efficiency.
Liquidity Coverage Ratio (LCR) is used to measure liquidity risk. LCR is defined as the proportion of highly liquid assets held by an organization to ensure that they maintain an ongoing ability to meet their short-term obligations (cash outflows for 30 days) in a stress situation. Learn more here.
For every blockchain, the Mempool (short for Memory Pool) is a database of unconfirmed transactions. As soon as a transaction is submitted by a user, it gets to the Mempool and as soon as a transaction is picked up in a new block, it gets removed from the Mempool.
Short for Maximum Extractable Value, in the past Miner Extractable Value. The term refers to the profit someone can make by adding, removing or rearranging transactions in the new blocks that are produced by a blockchain. Please find more details here.
An Optimistic Rollup is a Layer-2 scaling technique developed by the Optimism Foundation, that is used by major L2 like Optimism and Arbitrum. Optimistic Rollups assumes every transaction is valid (until proven that it is false) and bundle several transactions into one single transaction, that is then published to the Ethereum execution layer.
A Perpetual Swap is a form of a futures contract that allows speculation (with leverage) on future price movements of a token without an expiration date. Most of these swaps are collateralized with stablecoins and allow for Long (rising prices) or Short (falling prices) positions.
A Put option gives the right to sell an underlying asset for a specific price within a specific period of time.
A token that tries to maintain a stable exchange rate to an established fiat currency is called stablecoin. Thus, most stablecoins try to maintain a 1:1 peg to the US-Dollar.
For Proof-of-Stake blockchains, Staking refers to locking your funds in the native crypto asset of the blockchain to secure the network and be rewarded when a new block is mined and attached to the blockchain.
Short for Traditional Finance, so the existing financial infrastructure and the banking system with centralized parties like the Central Banks, Banking institutions and the government.
A loan without any form of collateral as security based on some basis of prior credit or evidence of future cash flows to sustain the obligation.
Yield farming is a popular strategy in DeFi to boost your yield by lending and re-investing token in various protocols to earn high returns in form of additional token.
