Transfer

eth.token.transfers.v1.Transfer

stringschema = 1

Schema is the string representation of one of the enum defined in Schema. We use it as a String here because Rust code uses a u32 for its representation but it's nicer for the file format to have the type as a string.

stringtrx_hash = 2

The transaction hash that generated that transfer.

uint64log_index = 3

The index of the log within the transaction's receipts of the block.

stringfrom = 4

The person that received the transfer, might not be the same as the one that did initiated the transaction.

stringto = 5

The person that received the transfer.

stringquantity = 6

How many token were transferred in this transfer, will always be 1 in the case of ERC721.

stringtoken_id = 7

TokenID the identifier of the token for which the transfer is happening. Only available when schema = ERC721 or schema = ERC1155. When schema = ERC20, the token id will be empty string "" as the contract itself is the token identifier.

stringoperator = 8

Operator is the "sender" of the actual transaction that initiated the transfer, it's equal to msg.sender within the smart contract. This will be different than from in case of Approval for example. Only available if schema = ERC1155, for ERC20 and ERC721, this will be the empty string "".

substreams.sink.files.v1

Linesmain

substreams.sink.files.v1.Lines

Lines represents an ordered list of lines that have been extracted of a single block. You are free the format each line as you please, the substream-sink-files tool does not make any assumption about the content and simply write the content to the current bundle with a trailing new line.

It is expected that your line do not contain a new line character as it will be managed manually by the substream-sink-files tool.

The most common use case is to use CSV or JSONL format for your line. For example, you can extract each transaction out of the block as a single line in JSON format as an object. The substream-sink-files will then package them in a bundle for N blocks.
