Buying an Address

Using manyzeros.xyz you can easily buy a vanity address. Once purchased it can immediately be used to deploy your contract.

Zero Addresses​

Zero Addresses are pre-mined vanity addresses with leading zeros like 0x000000000000b361194cfe6312EE3210d53C15AA. They can make your contract cost less gas when used stored in calldata or when used to store data more compactly in contract storage.

Custom Addresses​

The site also allows you to request a custom address with a certain number of specified digits/letters. When you make a request we mine it for you automatically before fulfilling the request automatically on-chain.

Once the request is placed you will not need to take any additional action.

note

In the event that our service should shutdown/disappear for any reason before your request is fulfilled the contract has a trustless refund process you can trigger.

Getting your Address on Other Chains​

When you buy your address you initially only receive the token on Ethereum mainnet. To receive the token on other chains the website will give you a cross-chain authorization.

note

The cross-chain authorization is only granted after a delay to protect against Ethereum reorgs.

You can claim the token on another chain by submitting the authorization via a call to the following function:

function claimGivenUpWithSig(
    address to,
    uint256 id,
    uint8 nonce,
    address claimer,
    uint256 deadline,
    bytes memory signature
) external;

The to address receives the token, the claimer is who the authorization was granted to. The signature is the signature of the owner embeded in the id.

The authorization is entirely chain independent, given a valid signature on one-chain it will be valid on all other chains as well. This ensures you can trustlessly claim your address without depending on bridges.
