@ASvanevik@nanexcool@MartinLSanchez@etherscan AFAIK they rely on Transfer events for Transfer overview (ignoring Mint + Burn events, expecting token contracts to also emit Transfer events from/to 0x0 address).
For balances they use getBalance.
For historical balances, probably checkpointing if indexer notices balance change.
@nanexcool@BitcoinSuisseAG@svantetobias You are very welcome 👌 It is great to get them out in the wild! Btw, you don't actually have to uncover the priv key.. The DAI notes will by proxy auto-convert themselves to ETH notes once Emergency Shutdown of SAI effectuates - in turn adding a bunch of vintage value 😉
