在上一课中，我们介绍了如何在OceanOne交易比特币。OceanOne支持交易任何Mixin Network上的token，包括所有的ERC20和EOS token，不需要任何手续和费用，直接挂单即可。下面介绍如何将将一个ERC20 token挂上OceanOne交易！
此处我们用一个叫做Benz的ERC20 token为例。这个token已经被充值进Mixin Network，你可以在区块链浏览器看到这个token在Mixin Network内部的总数和交易
预备知识:
先将Benz币存入你的钱包，然后使用getAssets API读取它的UUID.
取得该币的UUID
调用 getAssets API 会返回json数据, 如:
- asset_id 币的UUID.
- public_key 该币的当前钱包的地址.
- symbol 币的名称. 如: Benz.
if ($line == 'aw') { $mixinSdk_eachAccountInstance = GenerateWalletSDKFromCSV(); $asset_info = $mixinSdk_eachAccountInstance->Wallet()->readAssets(); foreach ($asset_info as $key => $asset) { echo $asset["symbol"] . " " . $asset["asset_id"] ." ". $asset["balance"] . " ". $asset["public_key"].PHP_EOL; }}调用 getAssets API的完整输出如下:

- 挂限价买单 低于或者等于市场价的单.
- 挂限价卖单 高于或者是等于市场价的单.
OceanOne支持三种基类价格: USDT, XIN, BTC, 即: Benz/USDT, Benz/XIN, Benz/BTC, 这儿示范Benz/USDT.
限价挂卖单.
新币挂单后,需要等一分钟左右，等OceanOne来初始化新币的相关数据.
if ( $ocmd == 's1') { $p = readline("Input the Price of XIN/USDT: "); $a = readline("Input the Amount of XIN: "); $tMemo = GenerateOrderMemo("A",USDT_ASSET_ID,$p); echo $tMemo . PHP_EOL; $mixinSdk_WalletInstance = GenerateWalletSDKFromCSV(); $asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(XIN_ASSET_ID); print_r($asset_info); if ( (float) $asset_info["balance"] >= (float) $a ) { $transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(XIN_ASSET_ID,OCEANONE_BOT, $mixinSdk_WalletInstance->getConfig()['default']['pin'], $a, $tMemo); print_r($transInfos); echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL; } else { echo "Not enough XIN!\n";}}限价挂买单.

PHP_EOL; } else { echo "Not enough USDT!\n";}}读取币的价格列表
读取币的价格列表，来确认挂单是否成功!
if ( $ocmd == '2') { getOceanOneMarketInfos(ERC20_BENZ,USDT_ASSET_ID);} function getOceanOneMarketInfos($targetCoin, $baseCoin) { $client = new GuzzleHttp\Client(); $baseUrl = "https://events.ocean.one/markets/".$targetCoin."-".$baseCoin."/book"; $res = $client->request('GET', $baseUrl, [ ]); if ($res->getStatusCode() == "200") { // echo $res->getStatusCode() . PHP_EOL; $resInfo = json_decode($res->getBody(), true); echo "Side | Price | Amount | Funds" . PHP_EOL; foreach ($resInfo["data"]["data"]["asks"] as $key => $exchange) { echo $exchange["side"] .
