 This BEP proposes to securely and smoothly decommission the build-in decentralized exchange on BNB Beacon Chain.
 
 ## 2. Abstract
-BNB Beacon Chain's primary focus, its native decentralized application ("dApp") BNB DEX, has demonstrated its low-latency matching with large capacity headroom. With the evolution of the framework, the high-speed DEX became a burden of the whole BNB ecosystem. After implementing this BEP, the DEX module will be disabled.
+BNB Beacon Chain’s primary focus, its native decentralized application ("dApp") BNB DEX, has demonstrated its low-latency matching with large capacity headroom. With the development of BNB Smart Chain and AMM-based decentralized exchanges running well on it, BNB DEX has less usage and liquidity. After implementing this BEP, the DEX module will be disabled, which will give Beacon Chain more computing power for the future computing and governance focuses.

 Decommissioning the DEX module will reduce the need for system resources significantly for both validators and full nodes. The demand for liquidation can be fulfilled by BNB Smart Chain or the upcoming zkBAS.
 
 ## 5. Specification
-After the implementation of this BEP, transactions related to DEX(including `NewOrderMsg`, `ListMsg`, `ListMiniMsg`, etc) will return an error to disable listing new trading pairs or placing any new orders.
-All the existing orders will be canceled either by traders or by 3 days timeout. Thus there will be no more DEX transactions on Beacon Chain.
+After the implementation of this BEP, transactions related to DEX(including `NewOrderMsg`, `ListMsg`, `ListMiniMsg`) will return an error to disable listing new trading pairs or placing any new orders.
+All the existing orders will be canceled either by traders or by 3 days timeout(or 30 days for orders in the best 500 price levels, according to [BEP-67](https://github.com/bnb-chain/BEPs/blob/master/BEP67.md)). Thus there will be no more DEX transactions on Beacon Chain.
 
 ### 5.1 Safety
 After the implementation of this BEP, there will be no more new orders.
 The existing orders which are not matched yet will not be matched anymore.
-They can be canceled by the traders directly or by timeout automatically after 3 days, and refunded to the traders.

 All the funds are SAFU.
 
 ### 5.2 Impact
-
-- For funds holders. It's recommended to refer to [this documentation](https://docs.bnbchain.org/docs/learn/cross-chain-transfer) to transfer existing tokens to BNB Smart Chain for more use scenarios.
-- For token owners. For tokens already issued on BNB Beacon Chain, It's recommended to transfer to BNB Smart Chain. For new token issue demand, it's recommended to issue on BNB Smart Chain directly.
-- For market makers. It's recommended to migrate to other DEXs on BNB Smart Chain. There is also an upcoming zkBAS which will provide an AMM DEX with high performance and low latency. Keep an eye on that.

-### 5.3 Decommission Plan
-
-1. Activate the hardfork.
-2. Wait for at least 1 week, confirm that there are no new orders and all existing orders are canceled.
-3. Decommission associated services.

-### 5.4 Others
 Transactions `MsgSubmitProposal` with type of `ProposalTypeListTradingPair` or `ProposalTypeDelistTradingPair` are used for submitting proposals to list new trading pairs or delist trading pairs.
 
 They might be not useful any longer but still valid after the BEP. It's not encouraged to send these transactions anymore.
