ERC4626 Token Vault Indexer

This repository contains an indexer for OpenZeppelin Tokenized Vault Contracts (ERC4626) that facilitates easy querying and presentation of tokenized vault events through a custom GraphQL API with Envio.

Schema and Event Details

The schema includes three main types: TokenVault, Deposit, and Withdrawal. The TokenVault type stores information about the tokenized vault, such as assets, shares, proportions, and exchange rates. Deposit and Withdrawal types capture details about corresponding events, including sender, owner, assets, shares, and the associated vault.

Event Occurrence:

• Deposit Event: Captures details when liquidity is added to the vault.
• Withdrawal Event: Records information when liquidity is removed from the vault.
