Definition. The total amount of gas consumed by the Ethereum network by transaction category. Transactions are classified into the following categories:

• Vanilla: Pure ETH transfers between externally owned accounts (EOAs) with no contract calls.
• ERC20: Transactions calling ERC-20 contracts. Contracts in the Stablecoins category are excluded here.
• Stablecoins: Fungible tokens whose value is pegged to an off-chain asset, either by the issuer or by an algorithm. The category includes 150+ stablecoins, with USDT, USDC, UST, BUSD, and DAI the most prominent.
• DeFi: On-chain financial instruments and protocols implemented as smart contracts, including decentralized exchanges (DEXs). The category includes 90+ DeFi protocols such as Uniswap, Etherdelta, 1inch, Sushiswap, Aave, and 0x.
• Bridges: Contracts allowing transfer of tokens between different blockchains. The category includes 50+ bridges such as Ronin, Polygon, Optimism, and Arbitrum.
• NFTs: Transactions interacting with non-fungible tokens. The category includes both token-contract standards (ERC-721, ERC-1155) and NFT marketplaces (OpenSea, Blur, LooksRare, Rarible, SuperRare) for trading them.
• MEV Bots: Miner Extractable Value (MEV) bots execute transactions for profit by reordering, inserting, and censoring transactions within blocks.
• Other: All other Ethereum transactions not included in the categories above.
