1.ethereum.erc1155_approval_for_all
Table Description
ERC1155_approval_for_all is an event related to the ERC1155 token standard on the Ethereum blockchain. This standard is designed to enable a single contract to manage multiple token types, both fungible and non-fungible. The approval_for_all functionality is an important part of this standard.In the context of ERC1155, approval_for_all is a method that allows a token holder to give approval to another address (often referred to as an operator) to manage all of their tokens within the particular ERC1155 contract. This is useful in scenarios where a user wants to allow a third-party smart contract or another user to transfer tokens on their behalf without having to approve each transaction individually.

2.ethereum.erc1155_transfer_batch
Table Description
ERC1155_transfer_batch in blockchain data refers to a batch transfer operation using the ERC1155 standard on a blockchain network, particularly Ethereum. ERC1155 is a multi-token standard that allows for the creation and management of multiple types of tokens, including fungible (like ERC20) and non-fungible tokens (like ERC721), within a single contract.In the ERC1155 standard, the transferBatch function enables users to transfer multiple types of tokens to several recipients in a single transaction. This approach is efficient as it reduces the number of transactions that need to be sent, thus saving on transaction fees and reducing congestion on the blockchain.

3.ethereum.erc1155_transfer_single
Table Description
The ERC1155_transfer_single event is part of the Ethereum blockchain’s ERC1155 standard. This standard allows for the creation and management of both fungible (similar to ERC20) and non-fungible tokens (similar to ERC721) within a single smart contract. In contrast to the ERC1155_transfer_batch event, which facilitates the transfer of multiple token types in a single transaction, the ERC1155_transfer_single event is emitted for single-token transfers. This event is used when a user or a smart contract transfers a specific amount of a particular type of token to another address.

4.ethereum.erc1155_uri
Table Description
The ERC1155_URI event in the blockchain’s ERC1155 standard is particularly significant for addressing how metadata is associated with the tokens managed under this standard. ERC1155, known for its efficiency in handling both fungible (like ERC20) and non-fungible tokens (like ERC721) within a single contract, also provides a flexible mechanism for linking token types to metadata.In ERC1155, the URI event (often referred to as ERC1155_URI) is emitted when the URI for a token type is set or changed. The URI is a Uniform Resource Identifier that points to a resource where metadata for the token can be found. This metadata typically includes information such as the token’s name, description, image, and other attributes.

5.ethereum.erc20_approval
Table Description
The ERC20_approval event is a key component of the ERC20 token standard, one of the most widely used token standards on the Ethereum blockchain. ERC20 tokens are fungible tokens, meaning each token is identical and holds the same value as others of the same type, much like traditional currencies. In the ERC20 standard, the approval function and the corresponding Approval event play a crucial role in enabling delegated token transfers. This feature allows token holders to give permission to another account, typically a smart contract or another user, to transfer a specified amount of their tokens on their behalf. This mechanism is essential for many decentralized applications (dApps) and services within the Ethereum ecosystem.

6.ethereum.erc20_balances
Table Description
ERC20 balances refer to the quantity of ERC20 tokens held in a particular Ethereum wallet. ERC20 is a standard for tokens on the Ethereum blockchain, providing a set of rules that all Ethereum-based tokens must follow. To check the balance of ERC20 tokens in a wallet, you can use various blockchain explorers or wallet applications that connect to the Ethereum network. These tools allow you to enter a wallet address and view the balance of all ERC20 tokens that the wallet holds. The balance is typically displayed in the token’s units and can be affected by transactions such as transfers and token swaps.

7.ethereum.erc20_balances_historical
Table Description
To view historical balances of ERC20 tokens for a specific Ethereum wallet, you would typically use blockchain explorers that support historical data queries. These platforms can track and display the balance of ERC20 tokens in a wallet at any given point in the past. This is possible due to the immutable nature of blockchain transactions. Each transaction is recorded and can be queried to reconstruct the balance of a wallet at a particular time. However, this process might require advanced tools or APIs provided by blockchain analytics platforms.

8.ethereum.erc20_transfer
Table Description
The ERC20_transfer event is a fundamental component of the ERC20 token standard on the Ethereum blockchain. ERC20 tokens are fungible, meaning each token is identical to every other token of the same type, similar to traditional currencies. This standard is widely adopted for the creation of fungible digital assets on Ethereum. In ERC20, the transfer function and the corresponding Transfer event are critical for moving tokens from one account to another. This is the primary mechanism through which token balances are adjusted within the network.

9.ethereum.erc721_approval
Table Description
The ERC721_approval event is an integral aspect of the ERC721 token standard on the Ethereum blockchain. ERC721 tokens are non-fungible tokens (NFTs), meaning each token is unique and can represent distinct assets, such as digital art, collectibles, or real estate.In the ERC721 standard, the approval function and the associated Approval event are crucial for enabling delegated transfers of individual tokens. This feature allows a token owner to grant permission to another account, typically another user or a smart contract, to transfer a specific ERC721 token on their behalf. This is particularly useful in scenarios where an NFT needs to be managed or utilized by a third party, such as in a marketplace or a game.

Table Sample
10.ethereum.erc721_approval_for_all
Table Description
The ERC721_approval_for_all event is a key feature of the ERC721 token standard on the Ethereum blockchain, which is primarily used for non-fungible tokens (NFTs). Unlike the ERC721_approval event that pertains to granting permission for a single NFT, ERC721_approval_for_all involves granting permission to an operator (another address) to manage all of an owner’s NFTs within a specific contract. This functionality is particularly useful in scenarios where an owner wants to allow a marketplace or another application to manage all their NFTs. It streamlines interactions with various applications by avoiding the need for approval on a per-token basis.

11.ethereum.erc721_transfer
Table Description
The ERC721_transfer event is a crucial component of the ERC721 token standard on the Ethereum blockchain. ERC721 tokens are non-fungible tokens (NFTs), meaning each token is unique and can represent individual assets, such as digital art, collectibles, real estate, or other unique items. In the ERC721 standard, the transfer function and the corresponding Transfer event are central to the movement of these unique tokens from one account to another. This is the primary mechanism through which ownership of NFTs is reassigned.

14.ethereum.nft_holders
Table Description
NFTs are unique digital assets that are stored on a blockchain, which is a decentralized and distributed digital ledger. Unlike fungible tokens like cryptocurrencies, where each unit is identical and interchangeable, each NFT is distinct and cannot be exchanged on a one-to-one basis with another NFT. This uniqueness is what makes them valuable for representing ownership of specific digital or tokenized physical assets. NFTs are commonly used for digital art, collectibles, virtual real estate, gaming items, and other digital goods that require proof of ownership and authenticity.
