An address to address map with iteration, deployed as a shared library
Historical Significance
Part of a 2016 attempt to sell working organisations as deployable parts: a governance contract, a token or a payment splitter bought from a counter for a fee, with the created contract's shape published on chain beside it.
Context
Deployed in the Homestead era, when deploying a contract meant compiling one yourself.
Key Facts
Description
AddressMap is a data structure library from Airalab's DAO toolkit. It pairs a mapping from address to address with a list of the keys, so a contract can both look a value up in one step and walk every entry in order, which a bare Solidity mapping cannot do. Deployed on 19 October 2016 by 0x4af013afbadb22d8a88c92d68fc96b033b9ebb8a and recovered from airalab/core. Etherscan cannot verify it: solc writes its link placeholder as the library name in lowercase at this vintage and Etherscan will not resolve that, so this record is the published form.
