# ADO V2 -> ADO V3

Old V2.0 Contract: 0x717926326fAb42c12E7d6102e2CD6c43683aA1ae

The idea of the V3.0 contract came up in early December when we discovered the need to remove on-chain tax so we can introduce Ado Travel, Ado NFTs and Ado Earn.

V3.0 was airdropped to V2.0 holders after a snapshot at a ratio of 1:1 and we've kept the affiliate levels of previous holders.

Improvements and bug fixes of ADO V3.0:

* rebrand Ado.Network to Ado Protocol
* change the website from [www.ado.network](http://www.ado.network) to [www.adoprotocol.com](http://www.adoprotocol.com)
* no on-chain tax for any transfer of ADO
* 3 tax levels with adjustment to max referrals payout: 10/10; 5/5; 2/2
* possibility to remove tax completely which also burns the holdings of the affiliate contract
* loyalty rewards (raffle) removed (gambling laws in some jurisdictions)
* BNB rewards removed (securities laws in some jurisdictions)
