Link addresses on chain

Anyone can use the Bloom Protocol smart contracts using any address. Bloom supports regular EOA addresses or smart contracts like multisigs. The Account Registry Logic contract enables users to demonstrate ownership of multiple addresses by linking the addresses on chain.

Contract name Network Address

AccountRegistryLogic Rinkeby 0xAe89E1c6E82e3cd602EEa08A1C40cAf110dB9295

Links are stored as a mapping from an address to a linkId. Users can have any number of addresses point to the same linkId. A linkId of 0 indicates that an address does not have any active links

mapping(address => uint256) public linkIds;


Public Functions




When the contract is first deployed it is in an initializable state. The deployer specifies an address that has privileges to migrate data from a previous version of account registry. Once initialization is complete the initializer relinquishes this privilege.

Account Registry Logic emits events when the user addresses are linked or unlinked.

event AddressLinked(address indexed currentAddress, address indexed newAddress, uint256 indexed linkId);
event AddressUnlinked(address indexed addressToRemove);
