Token senden und Guthaben prüfen

Ich möchte besser verstehen, wie ich überprüfen kann, wie viel von einem Token sich in meinem Konto befindet, und wie ich diesen Token an eine andere Adresse senden kann.

Angenommen, ich besitze eine Melone (MLN) und möchte überprüfen, wie viel ich habe. Ich habe wie folgt vorgegangen:

var tokenContractABI = [{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}]," zahlbar":false,"type":"function"},{"constant":true,"inputs":[],"name":"minter","outputs":[{"name":""," type":"address"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_spender","type":" address"},{"name":"_value","type":"uint256"}],"name":"approve","outputs":[{"name":"success","type":" bool"}],"zahlbar":false,"type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type": "uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"newAddress","type":"address"} ],"name":"changeMelonportAddress","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":" sender","type":"address"},{"name":"recipient","type":"address"},{"name":"amount","type":"uint256"}]," Name":"transferFrom","outputs":[{"name":"success","type":"bool"}],"payable":false,"type":"function"},{"constant":true," input":[],"name":"decimals","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function" },{"constant":true,"inputs":[],"name":"endTime","outputs":[{"name":"","type":"uint256"}],"payable" :false,"type":"function"},{"constant":true,"inputs":[],"name":"MAX_TOTAL_TOKEN_AMOUNT_OFFERED_TO_PUBLIC","outputs":[{"name":"","type" :"uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"newAddress","type":"address"}] ,"name":"changeMintingAddress","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name":"_owner ","type":"address"}],"name":"lockedBalanceOf","outputs":[{"name":"balance","type":"uint256"}],"payable":false, "type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"}],"name":"balanceOf","outputs ":[{"name":"balance","type":"uint256"}],"payable":false,"type":"function"},{"constant":true,"inputs":[]," name":"startTime","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant": false,"inputs":[{"name":"recipient","type":"address"},{"name":"amount","type":"uint256"}],"name":"mintIcedToken ","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"recipient","type":" die Anschrift"},{"name":"amount","type":"uint256"}],"name":"mintLiquidToken","outputs":[],"payable":false,"type":"function"},{"constant ":true,"inputs":[],"name":"symbol","outputs":[{"name":"","type":"string"}],"payable":false,"type ":"function"},{"constant":true,"inputs":[],"name":"MAX_TOTAL_TOKEN_AMOUNT","outputs":[{"name":"","type":"uint256"} ],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"recipient","type":"address"},{"name ":"Betrag","type":"uint256"}],"name":"transfer","outputs":[{"name":"success","type":"bool"}],"payable":false ,"type":"function"},{"constant":false,"inputs":[{"name":"recipient","type":"address"}],"name":"unlockBalance"," Ausgänge":[],"zahlbar":false,"type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"} ,{"name":"_spender","type":"address"}],"name":"erlaubnis","outputs":[{"name":"remaining","type":"uint256"} ],"bezahlbar":false,"type":"function"},{"constant":true,"inputs":[],"name":"melonport","outputs":[{"name":""," type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"THAWING_DURATION","outputs": [{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"inputs":[{"name":"setMinter"," type":"address"},{"name":"setMelonport","type":"address"},{"name":"setStartTime","type":"uint256"},{"name":" setEndTime","type":"uint256"}],"payable":false,"type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_from ","type":"address"},{"indexed":true,"name":"_to","type":"address"},{"indexed":false,"name":"_value", "type":"uint256"}],"name":"Transfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name": "_owner","type":"address"},{"indexed":true,"name":"_spender","type":"address"},{"indexed":false,"name":"_value ","Art":"uint256"}],"name":"Approval","type":"event"}] // Melonenvertrag ABI

var tokenContract = eth.contract(tokenContractABI).at("0xbeb9ef514a379b997e0798fdcc901ee474b6d9a1") // das ist die Adresse des Melonenvertrags

tokenContract.balanceOf(eth.coinbase) // Guthaben prüfen

Dies scheint eine übermäßig umständliche Methode zu sein, um den MLN-Saldo auf meinem Konto herauszufinden. Kann man etwas sauberer machen? Darüber hinaus möchte ich jetzt MLN-Token an eine andere Adresse senden, aber es ist mir nicht klar, wie das geht.

Danke für die Hilfe.
