Reentrancy contract from the June 17, 2016 DAO attack. Its owner triggered recursive splitDAO calls to drain The DAO. Exact structural source reconstruction.

DAO drain contract deployed by the attacker EOA on June 15, 2016. Byte-identical to the primary reentrancy exploit. Structural reconstruction.

The classic Frontier 'greeter' (Jan 2016): a mortal-derived contract storing a constructor-set greeting returned by greet(), with an owner-only kill().

A token with transfers and allowance spending, and an owner who can mint new units, deployed June 2016.

The first Ethereum token to implement an on-chain, increasing-difficulty hash-based minting mechanism.

A mineable subcurrency where claimMiningReward() mints 1 token to block.coinbase once per block. Deployed Jun 16 2016.

Gold (G), a 5 decimal token holding just 1.5 whole units, deployed 19 June 2016.

DAO reentrancy exploit redeployed June 19, 2016, after the attack. Byte-identical to the drain contracts but never configured. Structural reconstruction.
