New DAS Reverse Record is live now! →


A future-proof, cross-chain decentralized account system

DAS is a decentralized, open-sourced and highly-compatible account system based on blockchains, in contrast to those centralized account systems such as cell phone numbers/email addresses/social accounts. It is the first cross-chain account system with the user of an account having full control and ownership of the account. DAS can be used as a digital assets collection account, and as an account for accessing general Internet services.

DAS Features

Personalized & Unique

All DAS accounts end in ".bit" and you can register in different languages, even emojis, such as "hi.bit", "你好.bit", "こんにちは.bit" and "🚀🌕.bit". Each DAS account is unique, as duplicate names cannot be registered.


You can register a DAS account without permission. After registration, you will be the one and only person who has full control over the account.

Compatible with all Public Chains

You can register and manage DAS using any public chain's private key, or even email; DAS accounts can be transferred between any public chain's addresses. (based on PW-SDK)

Flexible Records

You can set up any blockchain address, email address, web address, social account and any other data as a record for DAS.

If you own "alice.bit", then you are automatically granted a site of "", which you can access through a browser. By default, the site displays your NFT and your DAS account information; you can change the content to a static page on IPFS by editing records.

Open Source

As an infrastructure, DAS uses open source modules that can be maintained by developers worldwide.

Usage Scenario 1

DAS as a unified digital assets receiving account

You can add multiple addresses from different chains to your DAS records, so that when others need to transfer digital assets to you, they can simply enter your DAS account instead of the complicated address. You can even label the addresses to distinguish them.

Usage Scenario 3

DAS as a portal for Dapp or decentralized website *

The portal of a contract on the blockchain is its Hash, and the portal of a web page hosted on a decentralized store is also a Hash. By associating these hashes as a resolution record to a DAS account, users can access these services directly using their DAS account.

Usage Scenario 4

DAS as an end-to-end encrypted communication account *

End-to-end encrypted communication software such as WhatsApp and Signal still use real-name account systems such as cell phone numbers. DAS, on the other hand, is anonymous and decentralized. So we can build a truly end-to-end encrypted communication system based on DAS.

Usage Scenario 5

DAS as passwordless login authentication *

Each DAS account can be associated with a public-private key, and each DAS account is highly identifiable. Based on W3C's WebAuthn, DAS accounts can naturally be used as login authentication to third-party systems. The login method is changed from entering the account password to using the private key associated with the DAS account to sign the login operation, which can greatly improve the security and user experience.

Usage Scenario 6

As a token of honor *

If Alice is a top VIP customer of Coinbase, then Coinbase, as the owner of "coinbase.bit," can create a secondary account "alice.coinbase.bit," and map all of Alice's addresses in Coinbase to this secondary account.


For Alice, this is the official recognition of her VIP status from Coinbase, a status symbol.


If Alice needs to deposit to her Coinbase account, she can just enter "alice.coinbase.bit" in her wallets instead of logging in Coinbase for her deposit address.

We believe DAS can do much more than what is listed above, and we hope to cooperate with great minds to explore more scenarios for DAS.
