(EFG) dApp is created based on smart contracts architecture. The basic logic is the system to be fully decentralized. The dApp goal is decentralized finance (DeFi) and it has fixed total supply (of 1, 000, 000 tokens). All the tokens, including the basic system tokens (EFG and GPT) and collateral assets, are ECRC-20 standard which is similar with ERC-20 (Ethereum) standard. They are freely transferable by users, and they can be even delegate handling(allowance). Additionally, the system can also accept ECOC (the native coin).

The EFG dApp can be cross-platform. This can be done with 'wrapped tokens.' Any assets (native coins or tokens) on any blockchain can be swapped in a decentralized way (atomic swaps), with wrapped tokens moving back and forth between Ecochain and the other blockchains. Wrapped tokens follow ECRC-20 standard so that they can join the dApp without problems.

EFG dApp also includes an Oracle system and open source client for user interface and interaction with the blockchains. Oracle system obtains real-time exchange rates from many different trusted sources and injects them into smart contracts. All these mean that the system stays decentralized.

EFG token details EFG has a total and fixed supply of one million tokens. That means that tokens can't be created, minted, or burned. The token shares the same interface as the ERC-20 (Ethereum) standard, as already mentioned. The interface standard provides the owner's functionality to transfer, allow some other entity to act for him, or even act on behalf of the other owner (if he gets an allowance from him). In short, it is easy even for third parties to build tools or clients to interact with EFG token.
