Как из транзакции Ethereum получить токены а не eth?

Question

[yarovoi_ivan]

У меня есть контракт и токены и вот не могу взять историю транзакций
Вот код
var filter = web3.eth.filter({fromBlock:0, toBlock: 'latest', address: addr_contract });
filter.watch(function(error, result) {
var tx = web3.eth.getTransaction(result.transactionHash);
console.log(tx);
if (tx != null) {
console.log(" tx hash : " + tx.hash + "\n"
+ " nonce : " + tx.nonce + "\n"
+ " blockHash : " + tx.blockHash + "\n"
+ " blockNumber : " + tx.blockNumber + "\n"
+ " transactionIndex: " + tx.transactionIndex + "\n"
+ " from : " + tx.from + "\n"
+ " to : " + tx.to + "\n"
+ " value : " + tx.value + "\n"
+ " gasPrice : " + tx.gasPrice + "\n"
+ " gas : " + tx.gas + "\n"
+ " input : " + tx.input);
}
});

в переменной tx.value = 0 это эфиры а как токен взять ?
