Ethereum

ETH serves many roles within the Ethereum ecosystem:

• Transaction fees: Users pay with ETH to execute transactions and use or deploy smart contracts on the network. The fee, known as gas, compensates miners or validators for processing transactions, and is proportional to the computing effort required. More complex functions, such as NFT mints, tend to consume more gas than a simple token transfer.
• Smart contract execution: Developers use ETH to pay for computation in the execution of smart contracts powering decentralized applications (dApps), which run autonomously on Ethereum.
• Staking: Since Ethereum's transition to a proof-of-stake (PoS) consensus mechanism in 2022, Ether is staked by validators to secure the network. Validators must stake 32 ETH in return for a chance to validate blocks and receive staking rewards.
• Collateral in DeFi: ETH is a primary choice as collateral for loans and various financial instruments within DeFi platforms.

Ether's supply is affected by a combination of issuance and burning mechanisms. New ETH is issued as staking rewards, while some ETH is burned as part of transaction fees due to Ethereum Improvement Proposal (EIP) 1559, which was introduced to reduce ETH inflation by permanently removing a portion of transaction fees from circulation.

Ether (ETH) is natively available on the Ethereum mainnet. Additionally, Ethereum-based Layer 2 solutions like Optimism, Arbitrum, and Base also use ETH as their native token to pay for gas. These chains use the Ethereum Virtual Machine (EVM), ensuring cross-compatibility across networks.

ETH can be transferred between different EVM-compatible chains and Layer 2s through official bridges or cross-chain swaps on Matcha, allowing you to move your assets across networks while retaining functionality and value.

ETH can also be wrapped as WETH (Wrapped Ether) to adhere to the ERC-20 token standard, with WETH also found on many blockchains. WETH is particularly useful in DeFi, as it is easier to integrate WETH with applications designed for ERC-20 tokens than it is to integrate native ETH.

Ether (ETH) is part of the broader Ethereum project, which was initially proposed by Vitalik Buterin in 2013 and developed by a core team that included developers like Gavin Wood, Joseph Lubin, and others. Ethereum is now maintained by a large, decentralized group of developers, researchers, and community contributors worldwide. The Ethereum Foundation, a non-profit organization, plays a central role in managing development grants and guiding the protocol’s evolution.

Ether (ETH) is the native cryptocurrency providing utility token on the Ethereum network. Its primary use case is paying for gas fees on the Ethereum blockchain, but it also serves as a store of value, collateral in decentralized finance, and a staking asset in Ethereum's proof-of-stake (PoS) consensus mechanism. Unlike many ERC-20 tokens that operate on Ethereum, ETH is not bound by any specific token standard; it exists as the base asset of the Ethereum network itself.

Ether (ETH) was launched on July 30, 2015, alongside the launch of the Ethereum mainnet. ETH was distributed to early participants during a pre-launch crowd sale held between July and August 2014. During this event, participants could buy ETH in exchange for Bitcoin (BTC). The sale raised about $18 million and allocated approximately 60 million ETH to buyers, with an additional 12 million ETH set aside for the Ethereum Foundation and early developers.

ETH has no fixed supply cap, and new ETH is minted to reward validators for their role in securing the network. Ethereum's switch to proof-of-stake and the implementation of EIP-1559 introduced deflationary mechanics, where a portion of the transaction fees paid in ETH is burned, reducing the overall supply. The annual issuance of ETH has also decreased significantly since the transition to PoS, reducing inflationary pressure, and a growing amount of ETH being locked in staking contracts has further reduced the circulating supply.

MEV (Maximal Extractable Value) is a measure of the profits that validators can extract from onchain transactions by ordering transactions within a block. MEV is present because Ethereum allows validators some control over the order in which transactions are executed, giving rise to opportunities to front-run or sandwich attack transactions for profit.

MEV can cause issues such as higher gas fees and worse trade execution prices. You can avoid losing money to MEV by using private mempools through tools such as Matcha Auto or RFQ liquidity sources.
