ERC20 Events Arkive

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.

Dependencies

• Docker
• Full Archive RPC (Infura, Ankr, Alchemy, etc)
