      "body": "EtherDelta was once the only usable decentralized exchange for ERC20 tokens, but it has suffered from numerous issues and setbacks throughout the last several months. If you’re looking for a newer, safer alternative for decentralized Ethereum-based token trading, DDEX is a great platform to check out! The migration process from EtherDelta to DDEX is quick and smooth.\n\nIf your primary exchange was EtherDelta and you’re coming to DDEX, there are a few things that might cause confusion initially:\n1. Wrapping ETH and Unwrapping WETH vs Depositing and Withdrawing\n2. Limit orders\n3. Enabling Trading A New Token Type\n4. Token Listings\n\nThis article explains all of these in detail.\n\n-----------------------------------------------------\n \n**Wrapping ETH and Unwrapping WETH vs Depositing and Withdrawing**\n\nOne difference between EtherDelta and DDEX is a difference in approach to smart contracts for token security. In EtherDelta, users are familiar with the process of depositing ETH into EtherDelta, purchasing tokens, then withdrawing the tokens. **With DDEX, there is no depositing or withdrawals at all.** In DDEX’s interface, all of your tokens stay in your digital wallet — so if you buy some ZRX on DDEX, it immediately appears within your wallet: there is no extra step to withdraw it from the exchange!\n\nDDEX does this through utilizing the 0x protocol. There is one step though that can cause some confusion regarding 0x settlement: the need for “WETH”. WETH is simply wrapped ETH — ETH is not normally an ERC20 token itself, and it does not adhere to the typical rules that ERC20 tokens do. EtherDelta got around this through their smart contract structure which required depositing and withdrawing. 0x does this through “wrapping” the ETH into an ERC20 token called WETH. WETH is completely equal to ETH (always a 1:1 ratio), and can be converted back and forth on DDEX and a few other 0x websites (and other 0x relayers).\n\n<center>![p 1.png](https://steemitimages.com/DQmeGgnxhE7ZoXBd3H4XiiCLpaP4SpktaHig55nEYFjEJce/p%201.png)</center>\n<center>_Wrapping ETH and Unwrapping WETH section of DDEX.IO_</center>\n\n\nSo in order to buy a token using ETH on DDEX, you first have to wrap your ETH into WETH. This requires a transaction on the blockchain (Metamask will prompt when you click either of the buttons). \n\nWe also recommend adding the WETH token contract address to your MetaMask wallet. It’s nice just to see that the WETH stays in your wallet and isn’t held by some 3rd party.\n\n_WETH Contract Address: 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2_\n_WETH Symbol: WETH_\n_WETH Decimals: 18_\n\n---------------------------------------\n**Limit Orders**\n\nDDEX allows for limit orders. This is similar to what you would typically experience on centralized exchanges, but if your experience is primarily on EtherDelta it might be a bit unfamiliar. \n\n<center>![p2.png](https://steemitimages.com/DQmYjAwKLKxFB5dvZwWynakyJMcsK4mdmnk3PsU1tKtdDzs/p2.png)</center>\n<center>_An example of a limit order placement in DDEX_</center>\n\nRather than having to click on many individual orders manually to purchase or sell large quantities of tokens, you can simply place a single limit order on DDEX. The matching algorithm will find all current buy/sell orders within your limit and fill them immediately. If there is any left over, the remaining limit order will appear in the order book.\n\n<center>![p3.png](https://steemitimages.com/DQmbpNavxkTbE9Xw17eXq3u2NQd3pf2BEL19TkNVgDYdnHW/p3.png)</center>\n<center>_An example of the DDEX order book. Sell orders in Red, buy orders in Green._</center>\n\nThere are a few nice advantages here - really this is just a more user-friendly system. Most notably: typos will not result in such devastating consequences. For those that liked being able to click on an order to fill it, that capability still exists. Clicking on an existing order populates the buy/sell limit price accordingly.\n\n-------------------------------------------------------------------\n\n**Enabling Trading A New Token Type For Selling**\n\nIn order for the 0x Smart Contract to interact with your digital wallet, 0x relayers like DDEX require a one-time “enabling” before selling a new token type. \n\n<center>![p4.png](https://steemitimages.com/DQmRPgh1ttnSwyeTEu7DCHLNoRS3Egc8UEvY3Fn76MubWoo/p4.png)</center>\n<center>_You will see a green button similar to this picture when you go to sell a token for the first time._</center>\n\n**You will only need to enable selling a new token type once ever.** After that initial enabling, you can place as many sell orders as you want without additional prompting from MetaMask. \n\nWhen clicking this enable token button for the first time, MetaMask will prompt you to sign a transaction. After you accept the transaction, it typically takes less than 2 minutes for token trading to be enabled. That’s it! No more depositing/withdrawing tokens constantly.\n\n--------------------------------------------------------\n**Token Listings**\n\nOne thing a lot of users really enjoyed about EtherDelta was the vast number of different tokens they listed. If you’re concerned that DDEX only lists a couple of that tokens you are interested in trading and you need more options: you can actually request tokens to be listed here — https://medium.com/ddex/how-to-get-new-tokens-listed-on-ddex-a8117c4ed05c\n\n--------------------------------------------------------\n\n**Lower Fees**\n\nEtherdelta charges a 0.3% transaction fee plus gas cost for transactions, while DDEX charges only a 0.1% transaction fee plus gas cost. DDEX also has a tooltip that automatically estimates your fee for a given order depending on the current Ethereum network traffic. \n\n--------------------------------------------------------\n\n**Summary**\n\nThere are a few things that are really nice about the DDEX system coming from ED:\n- Everything stays in your wallet. You don’t have to constantly deposit and withdraw tokens and ETH\n- Limit orders are awesome\n- System is super fast and support is great\n\nCompared with EtherDelta, the DDEX platform provides a better overall experience, lower fees, and the customer support is excellent. While the volume is still a bit low now, that seems likely to change in the near future. I’m excited to have a new great DEX option available as users look for more decentralized trading options.",

In EtherDelta, users are familiar with the process of depositing ETH into EtherDelta, purchasing tokens, then withdrawing the tokens. **With DDEX, there is no depositing or withdrawals at all.** In DDEX’s interface, all of your tokens stay in your digital wallet — so if you buy some ZRX on DDEX, it immediately appears within your wallet: there is no extra step to withdraw it from the exchange!\n\nDDEX does this through utilizing the 0x protocol. There is one step though that can cause some confusion regarding 0x settlement: the need for “WETH”. WETH is simply wrapped ETH — ETH is not normally an ERC20 token itself, and it does not adhere to the typical rules that ERC20 tokens do. EtherDelta got around this through their smart contract structure which required depositing and withdrawing. 0x does this through “wrapping” the ETH into an ERC20 token called WETH. WETH is completely equal to ETH (always a 1:1 ratio), and can be converted back and forth on DDEX and a few other 0x websites (and other 0x relayers).\n\n<center>![p 1.png](https://steemitimages.com/DQmeGgnxhE7ZoXBd3H4XiiCLpaP4SpktaHig55nEYFjEJce/p%201.png)</center>\n<center>_Wrapping ETH and Unwrapping WETH section of DDEX.IO_</center>\n\n\nSo in order to buy a token using ETH on DDEX, you first have to wrap your ETH into WETH. This requires a transaction on the blockchain (Metamask will prompt when you click either of the buttons). \n\nWe also recommend adding the WETH token contract address to your MetaMask wallet.

You don’t have to constantly deposit and withdraw tokens and ETH\n- Limit orders are awesome\n- System is super fast and support is great\n\nCompared with EtherDelta, the DDEX platform provides a better overall experience, lower fees, and the customer support is excellent. While the volume is still a bit low now, that seems likely to change in the near future. I’m excited to have a new great DEX option available as users look for more decentralized trading options.",

ICO 势能强劲，2017年7月份单月， 6.65亿美金 融资额，是2017年1-5月总额的两倍\n    1. 所有的ICO平台，以太坊是现有最手环一尼姑的平台\n    2. 69/100个最具有价值的token是基于以太坊的\n4. 0x 已经和Ethfinex ， District0x ，Augur ， Melonport达成合作协议\n5. 0x 会帮助Bitfinex Spinoff Ethfinex， 和 ANX International \n    1. Bitfinex 是世界上最大的交易所之一， 24小时交易额在2.5亿美金 \n    2. 如果Ethfinex 会接近 Bitfinex的交易额，0x的会被重用\n    3. Bitfinex上线了 Omise GO, 和Santiment \n    4. 目前看来 Ethfinex会是未来的重心 \n6. 多家crypto fund背书 \n\n\n* * *\n\n担忧\n\n1. SEC 限制美国公民参与交易，可能被认定为Securities \n2. ICO 不能被MyEtherWalet 支持 ， 很多人不熟悉Metamask， Parity 交易界面， 提高了操作难度\n3. 0x只支持ERC20 Token， 如果另一个智能合约公链变得更受欢迎，需求可能大幅降低 \n\n\n* * *\n\n结论\n\n短期和长期看好0x\n\n短期交易\n\n1. 24 Million的 Hard Cap很容易被达到， 13793 注册成功 ， 每个人份额为1736 美金， 约为 5个ETH \n2. 和 Bitfinex 好的合作关系 \n3. Token没有锁定期， ICO结束立刻发放 \n\n长期持有\n\n1. ZRX 会有实用需求 \n2. 如果我们认为区块链技术会继续发展5-10年 ，市场的大小会数倍与现在\n    1. 如果有10000以上ERC 20 Token ， 去中心化交易协议必不可少\n3. 0x协议优于现有解决方案",
