@DenisCarriere or @YaroShkvorets how would you find the creation of a new token from parsing the blocks?

YaroShkvorets commented 1 year ago

We don't have an ERC-20 like standard, but the defacto standard is eosio.token contract. This would be the action to look for: https://bloks.io/transaction/b510b95094909d6c551be5136ba483946f2263d6c8ffa154be3b26685248ba66?tab=traces

First stab: https://github.com/EOS-Nation/substreams-monorepo/tree/develop/substreams/tokens Can be improved upon, but seems to work.

Implemented via https://github.com/EOS-Nation/substreams-antelope/tree/develop/substreams/eosio.token

StreamingFast team needs to implement kV Sink to make it useful
