Explore native markets, evaluate an exchange integration, or build payment and asset workflows. Graphene brings these paths together with on-chain records, visible fees, and an Ethereum-compatible API.
Token trading, liquidity, and swaps require the trust flag. Native GRPH is accepted separately.
Watch for changes
Governance can change the flag. Existing orders and pools are checked again when used; cancellations and liquidity withdrawals remain available.
Check the asset itself
A trust flag does not prove backing, redemption rights, a price peg, or liquidity. Borrowing also needs valid oracle coverage: an available on-chain price source.

Names such as USD, EUR, GOLD, or Silver identify tokens; they do not establish backing or a redemption promise. This list describes the selected network only.
KNOW THE COST BEFORE YOU ACT
Current fees. Plain numbers.
Graphene charges a governance-set base transaction fee. Some actions also have a module charge or a refundable deposit.

Plus the base transaction fee
Total on successful execution10.001 GRPH
Invoice payments
0.2% of the invoice’s gross payment, taken in the requested asset. Invoice creation also locks a refundable deposit: 10 GRPH. The deposit returns to the creator when the invoice is fully paid.
Governance proposal deposit
100 GRPH. Locked when proposing. Returned if quorum is reached; collected as a protocol fee if quorum is missed. The base transaction fee is separate.
Saved settings snapshot · live check pending · Checked:
A transaction that passes validation but fails during execution still pays the base fee. Swap and other module charges depend on the action. The final receipt records what was charged.
HOLDERS HELP SHAPE THE RULES
A clear path from proposal to change.
Graphene uses on-chain proposals and votes to change supported settings, token trust, token issuance, and fee-account actions.
01
Propose a supported change
Submit a proposal and lock its GRPH deposit. A proposal freezes its rules and takes voting eligibility from the parent committed block.
02
Vote with eligible GRPH
Lock a positive amount within your snapshot balance. Voting power is the integer square root of that amount, subject to a per-wallet cap. Each wallet votes once per proposal.
03
Meet both thresholds
The vote must reach quorum: the required share of eligible voting power. It must also reach the required share of yes voting power. Vote locks are released when voting ends.
04
Wait, then apply
A passed proposal waits for a timelock: a delay counted in blocks. The chain then rechecks and applies the change. A change that fails execution checks is rejected.
Current proposal rules
New proposals use the current settings below. Existing proposals keep the rules captured when they were created.
Durations are block counts, not seconds or calendar dates. Same-block transfers cannot increase a proposal’s snapshot power. Quadratic voting and a wallet cap do not by themselves prevent one person from controlling multiple wallets.

IDEAS, WITH BUILDING BLOCKS
Make it useful. Make it yours.
Native modules provide starting points for applications that move value and record activity.
01 / COMMERCE
From invoice to paid.
Build a payment flow that tracks contributions and shows a clear invoice status.
Native financial workflows.
One connected foundation.
Graphene combines native financial modules, a community trust policy, and governance-set transaction prices behind an Ethereum-compatible RPC API.
Useful modules already in the protocol
Start from native assets, orders, pools, invoices, attestations, and borrowing workflows. The application can focus on how people use them.
Shared trust and pricing rules
The protocol rechecks token trust in supported markets. Governance controls supported fee settings and changes through proposals.
Familiar tools at the edge
Use supported Ethereum JSON-RPC methods and the explorer while working with the network’s native modules.

Graphene’s value proposition is this integrated combination. Native modules and on-chain governance are also available in other stacks. This comparison does not establish a speed, security, adoption, or cost ranking.
FAMILIAR TOOLS. A NEW FOUNDATION.
Hello, Graphene.
Graphene exposes an Ethereum-compatible JSON-RPC endpoint alongside native state APIs. Start with a read-only request, then explore the modules behind it.
Set GRAPHENE_RPC_URL to your node’s endpoint. This request reads the latest block number; it does not send a transaction.
FOR EXCHANGE TEAMS AND PARTNERS
Start with a concrete integration brief.
Use this overview to begin a technical or commercial conversation. It describes the available building blocks and the questions to resolve for your chosen deployment.
Assets and network
Confirm the chain ID and node endpoints. GRPH is the native asset; other tokens are identified by their chain and address, with explicit decimals.
Transactions and operations
Check the supported Ethereum JSON-RPC methods, blocks, receipts, nonces, and fee settings. Test deposit crediting and withdrawal handling against the selected network.
Markets and business flows
Evaluate funded orders, liquidity pools, payment invoices, or attestations against your use case. A token trust flag controls eligibility in supported native markets.
A shared evaluation
Agree on the integration scope, required documentation, operational responsibilities, and acceptance tests with the team.

A FEW THINGS WORTH KNOWING
Good questions. Clear answers.
Understand the network, its tools, and the scope of these facts.
What are trusted tokens on Graphene?
+
Trusted tokens carry a governance-controlled flag that makes them eligible for native trading and trusted-token lending markets. Check the token’s chain and address, not just its symbol. Governance can revoke trust, and borrowing also depends on valid oracle coverage. The flag does not guarantee backing, a price peg, redemption, or liquidity.
What is the Graphene blockchain?
+
Graphene is a blockchain project that combines Tendermint consensus with a Java and Quarkus chain service. Its codebase includes native modules for assets, trading, payments, staking, attestations, and governance. An Ethereum-compatible RPC API and a React explorer provide ways to read and interact with the network.
Does Graphene use DPoS consensus?
+
The inspected workspace uses Tendermint consensus and includes validators and stake delegation. That does not establish the witness-based DPoS design associated with other projects named Graphene. This page describes this workspace only. Confirm the consensus configuration of the network you intend to use before relying on it.
Can I use Ethereum tools with Graphene?
+
Graphene exposes an Ethereum-compatible JSON-RPC endpoint, and its explorer uses Viem to interact with the network. Begin with read-only calls such as eth_blockNumber. Compatibility depends on the method and feature you need, so check the implementation and test your integration against your selected node before sending transactions.
What can I build with the native modules?
+
The codebase provides modules for tokens, funded orders, liquidity pools, payment invoices, staking, attestations, and governance. These can support asset and payment workflows without assembling every part yourself. Treat them as development building blocks: review the module rules, fees, and deployment configuration before designing an application around them.
How fast is Graphene, and what does it cost?
+
This page does not publish a throughput benchmark or a fixed block time. Actual timing depends on the network and its configuration. Protocol fee logic exists in the codebase, with prices controlled through governance. Read current network settings and inspect representative transactions to assess timing and costs for your application.
Where do the network figures come from?
+
The figures use the same state statistics endpoint as the explorer. Blocks and transactions reflect the indexer, while addresses reflect synced state. They may lag the chain and do not represent individual people. If the endpoint cannot be reached, the page shows an unavailable state instead of made-up numbers.
