Operators who work like intelligent
bots that help token holders

Any token holder can “authorize” or “revoke” the existence of third parties who can perform transaction of their behalf: operators. These operators may be only smart contracts who can work as autonomous intelligent systems that are able to manage accounts for the token holder. An operator can be in charge of managing one’s funds and execute regular functions like filling one’s hot account (the account one uses the most to make payments) by moving tokens from a more secure personal account periodically in a smart way. An operator can also be an intelligent exchange, a cheque processor or an automatic charging system. Operators can be seen as smart robots working for the token holder from inside the Blockchain. They offer high level of security. One can program the operator to be able to execute withdrawals only to one’s own address making it invulnerable to hacking.

Compatibility with any ERC20 wallet

ERC777 standard is backwards compatible with DApps that do not implement its advanced functions, like any wallet made for the ERC20 standard (all common wallets like MEW, MIST, MetaMask, etc.). This also means that any exchange supporting ERC20 tokens will be able to list our ERC777 token, CALL.

Updatable token functions that allow improvement

A token, as opposed to a coin, is basically a program running in a Blockchain constructed to be a super computer. The best example of a super computer of this kind is the Ethereum network. As any other computer program, a token contains a number of functions inside that are developed and implemented by software developers in computer code. Many tokens have the disadvantage that, after being deployed to the Blockchain, they cannot be modified. So, it is impossible to add new functionality to them. Un-scalability is one of the negative features that can make hundreds of tokens lose value in the future, since one has to destroy all the tokens and replace them with new ones to add one new function. CALL token solves this major issue by providing the capacity to update functionality and develop new versions of the token according to new future needs and advances.

Increased security

It has been a well known security issue in ERC20 standard, that, if a holder sends tokens to a smart contract, since most contracts can not verify if they are able to receive and administer the tokens properly, it is easy to end up getting one’s tokens locked in a smart contract forever. So far, millions of dollars are reported to have been lost because of this kind of errors. ERC777 solves this problem by improving the functions related to withdrawals whose target is a smart contract, and by analyzing the functions of the smart contract before the withdrawal is executed.


The First Powered By ERC777

Latest advanced Dapp-friendly features

ERC777 Standard uses the same kind of function Ether uses when sending coins; this enables the sending of information about the transaction together with the data of destination and amount; this way the sender of tokens can also specify details about the transaction.

Newest philosophy of genuine full control
of accounts for holders

Both contracts and regular addresses implement a modern paradigm of full control of the function of sending tokens by registering the destinations. Also all types of addresses implement a revolutionary paradigm of full control of the function of receiving tokens by registering unwanted tokens’ contract. This means token holders can choose to whom they want to send, or from whom they want to receive, tokens. The common ERC20 standard does not provide this level of freedom or free will. In ERC20 one cannot register in the Blockchain to whom one wants to deposit tokens. And the reception of tokens can happen as an imposition, because you are not able to reject unwanted tokens. ERC777 has solved these issues.

Batch Transfer - Capacity to execute 255 payments in one transaction

As with any form of computation performed on the Ethereum network, all token transactions must pay gas (Ether) for the network to process the transaction. Each transaction pays a certain amount of gas which for most tokens presents an issue when they are considered for massive adoption. CALL token implements one distinguishing feature: the capacity to execute up to 255 payments in one transaction, but pay a network fee equivalent to just one transaction.


Offers a wide range of transaction-handling mechanisms

Total Supply locked at 777 Million tokens

The maximum amount of CALL tokens that will ever exist is 777,000,000 tokens (777 Million CALL). Never will this amount of tokens increase. This total supply is locked by the smart contract and cannot be modified anytime in the future by any means.

GCA will not host an ICO

We have decided to seek an alternative route for funding. We will be hosting a private sale that will be by invitation or recommendation only, and when our services are ready to be offered. With this strategy, we can guarantee true value for early investors. If you are interested in updates, please fill in the early bird form.
