USDC transfers indexing squid

This example squid indexes USDC transfers by tracking the historical Transfer(address,address,uint256) logs emitted by the USDC contract on the Ethereum Mainnet. For an extensive reference of Squid SDK and the Subsquid ecosystem, go to the docs.

One can use this example as a template for scaffolding a new squid project with sqd init:

sqd init my-new-squid --template https://github.com/subsquid-labs/evm-logs-example

Prerequisites

• Node v16.x
• Docker
• Squid CLI

Navigate to the example folder.

npm ci
sqd build
# start the database
sqd up
# starts a long-running ETL and blocks the terminal
sqd process

# starts the GraphQL API server at localhost:4350/graphql
sqd serve
