This Arkive keeps an accurate historical record of the sharePrice of a given set of YearnV2 Abi Vaults. sharePrice increases as profits are distributed to the vaults, but may also decrease if loss is incurred. It may be valuable to track this information in case of incidents or in order to optimize the vaults for instance.

This Arkive keeps an accurate historical record of the balance of an account of a given ERC20 token. It uses the Balance entity as a mutable variable updates as events are handled and is used to keep track of an accounts balance as we sync eventually reflecting true onchain balance. BalanceHistory is an unchanging entity which stores balance over time and is indexed by the `block` field.

This Arkive has two entities, Transfer and Approval. The Arkive also has two corresponding event handlers onTransfer and onApproval which are triggered when the `Transfer` and `Approval` events are emitted by the source contract which is configured to `WETH` in the manifest. When the handlers are triggered they parse the amount and store either an Approval or Transfer entity in the database.
