For users who hold ERC-20 GRAM, the ERC-20 GRAM contract will be suspended and brand new contract address, 0x02163178f5de7e55eb3f4008a153523910e9d738 will be activated. OpenGram team will airdrop newly generated GRAM to users’ original ERC-20 addresses.

Powerful Protocol Support


GRAM has no limits on the size of your media and chats. Unawares network switch over Countries and all different situations.


GRAM uses an end-to-end encryption scheme so your privacy is fully protected. With end-to-end encryption, the content of your communications will not be decrypted by servers so your messages are protected against intrusions.


GRAM delivers messages faster than any other application based on public chain and private side node. We also provide a open source platform for developers worldwide to contribute into this open network protocol.

Instant Hypercube Routing

GRAM can grow new valid blocks on top of any blocks that were proven to be incorrect to avoid unnecessary forks. This self-healing mechanism saves resources and guarantees that valid transactions will not be discarded due to unrelated errors.
