What is Otterscan?

Created in 2021 by William Mitsuda, Otterscan is an Ethereum blockchain explorer built on top of Erigon. Users can run it locally on their laptops with an archive node companion, more specifically, with Erigon. Developers can use some custom methods created by Otterscan and implemented at rpcdaemon level so it is fast.
