About EtherGem (EGEM)

EGEM is the stable, pure, no pre-mine coin with applied technologies peernet and per block endowment.

What does that really mean, though?

EtherGem, "EGEM," is first and foremost, a pure community coin with no pre-mine. True to its roots as a cryptocurrency, the Proof of Work mining community will always be a part of EGEM's future and is the foundation of the EGEM launch. There is no ICO on EGEM and EGEM is its own primary blockchain, not just a token or concept on another chain. The EtherGem blockchain is an Ethereum network, meaning it starts with the tested and proven Ethereum (as in ETH) core technologies and builds from there. Technically, EGEM is an Ethereum chain as described in the yellow paper, with EIP150, EIP155, EIP158 applied from block 0. Block Rewards have 7 eras of reduction, including a dev reward enabled after block 5000. Developers and Community Managers are bound by a continuity agreement to maintain the network, community, and coin. There is no cap to EGEM at the moment. A monetary cap will be put in place when the community determines that the logical progression would be to cap the coin.

An "applied technologies peernet" is where the EtherGem blockchain grows on a mineable token sidechain. Dual mining ethergem and a token is something new. The EGEM sidechain is designed to be very much an integral part of ongoing mainchain development, where peers can implement new technology while continuing to rely on a solid foundation. The sidechain and token will be available shortly after the mainnet release.

Frequently Asked Questions

Q: What is the max supply of EGEM?
A: After the final era which is the 7th there will be roughly 45 million EGEM in circulation, and each year following will produce 350k new coins give or take.

Q: What makes you different than any other chain?
A: We have implemented our own difficulty adjustment per block to keep the chain under a 13 second average, and we also use a custom block halving scheme to slowly reduce the amount of coins that get created over time.

Q: Why the Name?
A: Ether - a medium that in the wave theory of light permeates all space and transmits transverse waves. Gem - something prized especially for great beauty or perfection.

Sapphire is an integrated sub-chain that interweaves the mainchain on EGEM and includes a DEX. It is dual-mineable with EGEM and companies can ICO on the multicurrency wallet and DEX - paying in EGEM, with proceeds enhancing the quarry node payments.

Work is Ongoing!

Product integration and growth

Fiat to crypto conversion capabilities, ATM development and implementation, integration of both with DEX.

Coming/Starting Soon!
Quarry (Master) Nodes

Interested in earning a return on your EGEM holdings? EGEM quarry nodes (a form of master node) allow node operators to receive EtherGem in exchange for running a node. There are currently two tiers of nodes:

As the EtherGem network grows, there are plans to add additional node tiers with increasing returns. This gives node investors the ability to exponentially grow their holdings as they acquire more EGEM. Click here to access the GitHub code for setting up a node.

EtherGem has a full-service Discord bot that allows you to manage your node(s). You can perform such actions as: registering a node, changing the IP address of a node, turning automatic payments on/off, checking your wallet balance. And also being able to set when you would like to have the system send node rewards.

Node Stats:

Nodes map updates every 24h.

You can store EGEM on the following wallets.

Give the OPAL desktop wallet a try here.

Ledger Trezor

We also have our own branded MEW located at

There will be more wallets and places to store EGEM as the project/platform evolves, We would also like to mention that it is never a good idea to store and/or mine to an exchange wallet, as things can and have happened in the past to other coins.


We are proudly listed on the following exchanges. The EtherGem team is actively engaged in talks with additional exchanges, and they will be listed here as they become available for trading.
