Exosama NFT collection

This sample squid indexes Exosama NFT transfers on the Ethereum Mainnet by subscribing to the Transfer logs. For each new batch, the processor detects the NFTs that have not yet been indexed and populates the metadata calling the contract state (see initTokens()). The contract state queries are batched using the Multicall contract and the Multicall facade class generated with sqd codegen. Note the --multicall flag in the codegen command defined in commands.json.

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/multicall-example
