1/ Over 44 MILLION contracts have been deployed to @ethereum since genesis 🤯

I analyzed all 44M using @InsightsFlow so you don’t have to.

Turns out, 70% of live contracts (~15M) are copies from one of 15 templates.

🧵 Here’s a breakdown of the dominant contract codes

2/ Destroyed contracts 💀

🏷️ ~50% of ALL contracts (~22M)

More 'anti-code' than code, but what does this mean? It means 'self-destruct' was called on the contract, removing all bytecode.

Why?
My guess is gas is to save gas ⛽ (see below)

3/ Gas Token contracts

🏷️ ~10% of live contracts (~2M)

To disincentivize state bloat, EVM refunds gas to a user for destroying a contract. This resulted in users deploying empty contracts when gas prices were low & destroying when high, for a quick refund 🎰.

4/ Forwarders

🏷️ ~50%+ of live contracts (~12M)

These are contracts deployed by exchanges as sth like a PO box for users. Gives user an address, custodied by exchange & allows exchange to collect ETH/ERC20s sent to user.

Often include various safety and batch tx mechanisms

5/ OwnableDelegateProxy

🏷️ ~0.5% of live contracts (~1M)

Created by @WyvernProtocol w/ @opensea as the biggest deployer. Deprecated but is essentially a "wallet-contract" created for selling NFTs (1 per wallet per collection)

6/ DSProxy

🏷️ ~0.1% of live contracts (~200k)

Created by @dapphub, can be considered a smart contract wallet. Common use case is to exec multiple actions in 1 tx (not possible w/ regular wallet)

E.g.
- Draw collateral from @MakerDAO vault > sell 4 DAI > pay back debt

7/ ENS Deeds

🏷️ ~0.7% of live contracts (~150k)

@ensdomains' deed contract was also in the top25, with over ~150k contracts.

These were created as part of the old ens domain registration mechanism, but are no longer in use.

8/ What about ERC20s, NFTS?

They didn't make the list! 😮

This is not to say they aren't popular, but there is enough variation in their code making them not _exactly_ the same.

Hint: there are over 400k ERC20s - stay tuned for a Part 2

9/ Like the thread and/or want to see a part 2 going over ERC20/721s?

correction: 1 OwnableDelegateProxy is created for each seller*
