These Terms govern your use of the website gembachain.io, the GembaBlockchain network, the testnet faucet, the contact form, the facility to acquire GMB through GembaPay, and the ecosystem dApps (together, the "Services"), operated by GEMBA EOOD, Bulgaria ("GEMBA", "we"). By using the Services you accept these Terms. If you do not accept them, do not use the Services.
Gemba (GMB) is the native utility token of GembaBlockchain. Its only functions are: (a) paying network gas (transaction fees), and (b) paying for the services of the ecosystem applications. GMB is acquired to be used inside the ecosystem.
For the avoidance of doubt, GMB is NOT: a security or financial instrument; a share, equity or ownership interest; electronic money or a deposit; a fund or collective-investment unit; or an investment of any kind. Holding GMB grants no ownership, voting rights in GEMBA, dividend, distribution, interest, or any expectation of profit. GMB confers only the right to use the ecosystem's services and to pay network gas.
GembaBlockchain is built for use, not for speculation. Accordingly: GMB is not listed on any exchange (centralised or decentralised); GEMBA provides no liquidity and operates no liquidity pool or market-maker; GMB has no market price; GMB cannot be redeemed for fiat currency; and there is no buyback. The only price is the fixed rate set by GEMBA: 1 GMB = €1. We do not promise, and you must not expect, that GMB can be resold or that its price will change. Any third-party market that might nonetheless appear is outside our control, is not operated or endorsed by us, and does not represent a price set or recognised by GEMBA.
You may acquire GMB through the GembaPay service (card or crypto) at the fixed rate 1 GMB = €1. Acquiring GMB means obtaining credit usable for the ecosystem's services and network gas — it is a purchase of utility, not an investment.
GMB is used to pay for the services of the Gemba ecosystem applications. Paying for a service in GMB grants a 20% discount versus the standard price — this discount is the purpose of holding GMB. The discounted fee is computed at the fixed rate 1 GMB = €1. The applications that accept GMB are:
The GMB you hold is meant to be spent on these services and on network gas — that is its purpose. See gmb.gembachain.io for exactly what GMB can and cannot be used for.
GembaBlockchain is permissionless: anyone may operate a validator under the published protocol rules (entry self-bond of 1,000–10,000 GMB, the network incentive schedule, the daily cap, the unbonding period and on-chain governance). The full rules and node software are open-source on GitHub. Operating a validator means providing a network service (producing and validating blocks) and receiving GMB as a network incentive / utility credit for that service. This is not a passive-income scheme and is not an investment: the GMB received is utility credit, intended to be spent on the ecosystem's services and on gas, not as financial gain. Validators bear their own operating costs and risks (including slashing for misbehaviour, per the published rules).
The live network (gemba-testnet-1, EVM chain ID 821207) is a public test network. Testnet GMB
and the test stablecoins are valueless and for testing only. The network may be reset, paused, upgraded or
discontinued at any time and balances may be lost.
The faucet dispenses small amounts of valueless testnet assets on an "as available" basis, subject to per-wallet cooldowns and limits. It may be rate-limited, paused or removed at any time. Automated abuse is prohibited.
You are responsible for your own wallets, private keys and addresses. We never have custody of your funds or keys, cannot recover lost keys or restore access, and cannot reverse transactions. Loss of your keys means permanent loss of access to your GMB.
You must be at least 18 years old and legally able to enter these Terms. You may not use the Services if you are located in, or a resident of, a sanctioned or prohibited jurisdiction, or where use would breach applicable law. You are responsible for complying with the laws that apply to you, including any tax obligations. Where we carry out identity (KYC) or anti-money-laundering (AML) checks in connection with a purchase, you agree to provide accurate information.
You acknowledge and accept that: the Services and network are provided "as is" without guarantee; loss of keys results in permanent loss of access; smart contracts may contain bugs or behave unexpectedly; blockchain and token regulation may change and affect the Services; and GMB may have no resale value and is not intended to be resold. Use the Services only if you understand and accept these risks.
The GembaBlockchain code is open-source (Apache-2.0); documentation is CC BY-SA 4.0. The software is provided "as is". Running a node or deploying contracts is at your own risk.
The Services and network are provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, availability, security or non-infringement.
To the maximum extent permitted by law, GEMBA and its team are not liable for any indirect, incidental, special or consequential damages, or for any loss of tokens, data or access, arising from the Services, the network or your use of GMB — including losses from incorrect addresses, irreversible transactions, network resets, smart-contract behaviour, or third-party services.
Certain network and treasury parameters are controlled by on-chain governance and time-locked execution, as described in the public documentation. Changes to the chain's own software are coordinated, documented node-operator upgrades.
The Services rely on third parties, including GembaPay (and, through it, payment providers such as Stripe/PayPal) and Cloudflare (security/anti-bot). Your use of those is also subject to their terms and privacy policies.
We may update these Terms at any time; the "Last updated" date will change. Continued use after an update means you accept the revised Terms.
These Terms are governed by the laws of the Republic of Bulgaria and applicable European Union law, without regard to conflict-of-law rules; disputes are subject to the competent courts of Bulgaria, to the extent permitted by mandatory law. Contact: [email protected].
