Definition. The number of transactions in the Ethereum network by category. Transactions are classified into the following categories:

• Vanilla: Pure ETH transfers between Externally Owned Accounts (EOAs), with no contracts being called.
• ERC20: All transactions calling ERC20 contracts. Contracts in the Stablecoins category are excluded here.
• Stablecoins: Fungible tokens that have their value 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 being the most prominent.
• DeFi: On-chain financial instruments and protocols implemented as smart contracts, including decentralized exchanges (DEXs). The category includes over 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. This category includes both token contract standards (ERC721, ERC1155) 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 transactions in the Ethereum network not included in the categories listed above.
