Blockchain for Developers: Build Scalable dApps
QIE is an EVM-compatible Layer 1 blockchain built for developers who need real throughput and predictable costs. Deploy your existing Solidity contracts, keep your MetaMask and Hardhat workflow, and ship on a chain built to handle 25,000+ transactions per second.
Why developers build on QIE
A blockchain platform for app development that removes the two biggest blockers to shipping a dApp: throughput and cost.
High-throughput by design
Full EVM compatibility
Near-zero, predictable fees
Built-in interoperability
Real developer support
Security without the overhead
Built for scalable dApp development
QIE Blockchain runs Delegated Proof-of-Stake consensus on top of Tendermint Core, the same consensus engine family used across the Cosmos ecosystem. Validators are chosen by stake delegation rather than energy-intensive mining, which is what lets the network finalize blocks quickly without sacrificing decentralization.
Because QIE is fully EVM-compatible, none of that architecture changes how you build. Your Solidity contracts, your Hardhat or Truffle deployment scripts, and your MetaMask-based user flows work exactly as they would on Ethereum. You're just deploying to a chain built to handle significantly higher transaction volume at a fraction of the cost.
QIE supports 25,000+ TPS versus roughly 4.6 TPS on Bitcoin and roughly 20 TPS on Ethereum's base layer, a meaningful throughput gap for high-frequency dApp use cases like gaming and trading.

How QIE compares for dApp development
The specs that actually affect a build decision: throughput, fees, and tooling compatibility.
| Factor | QIE Blockchain | What it means for your dApp |
|---|---|---|
| Consensus | Delegated Proof-of-Stake | Fast finality without Proof-of-Work energy costs |
| Throughput | 25,000+ TPS | Headroom for high-frequency use cases: gaming, trading, social |
| Block finality | < 2 seconds | Fast, near-instant confirmation for users |
| Avg. transaction fee | $0.0001 | Microtransactions and frequent interactions stay viable |
| Smart contract language | Solidity (EVM) | Reuse existing contracts and audits, no rewrite |
| Tooling | MetaMask, Hardhat, Truffle, Remix | Your existing deployment pipeline works unchanged |
| Developer funding | 5,000–500,000 QIE grants | Non-dilutive capital to scale past the prototype stage |
Frequently asked questions
The questions developers ask most before choosing a chain to build on.
Weigh four things against your app's actual requirements: transaction throughput and finality speed, gas costs at your expected usage volume, compatibility with existing tooling (EVM/Solidity support means you can reuse MetaMask, Hardhat, Remix, and Truffle rather than learning a new stack), and the strength of developer support such as documentation, testnets, and grant programs. A chain that's EVM-compatible with high throughput and low, predictable fees removes most of the friction of shipping a production dApp.
Scalability comes down to how many transactions a network can finalize per second without fees or confirmation times spiking under load. It's shaped by the consensus mechanism (Delegated Proof-of-Stake, for example, finalizes blocks faster than Proof-of-Work), block time, and how the network handles congestion. QIE Blockchain uses Delegated Proof-of-Stake consensus built on Tendermint Core to support 25,000+ transactions per second with block finality in under 2 seconds.
There's no single universal answer. It depends on your app's throughput needs, your budget for gas costs, and whether you want to reuse Ethereum-standard tooling. For teams that want Ethereum-compatible development (Solidity, MetaMask, Hardhat, Remix) combined with higher throughput and near-zero fees, QIE Blockchain is built specifically for that profile: EVM compatibility with 25,000+ TPS and an average fee of $0.0001.
The typical path is: get testnet tokens from the chain's faucet, connect your wallet (e.g., MetaMask) to the testnet, write and test your smart contract in Solidity using a tool like Remix or Hardhat, deploy to testnet and verify it behaves as expected, then deploy to mainnet once you're satisfied. On QIE Blockchain, testnet tokens are available free through the developer portal, and because QIE is EVM-compatible, the Solidity contracts and tooling you already know work without modification.
TPS (transactions per second) measures how many transactions a blockchain network can process and finalize each second. It matters for dApps because low TPS means slower confirmations and higher fees during periods of high demand, a problem for anything with frequent user interactions, like gaming, trading, or social apps. QIE Blockchain is built to support 25,000+ TPS, compared to roughly 4.6 TPS for Bitcoin and roughly 20 TPS for Ethereum’s base layer.
If the chain is EVM-compatible, the process is the same as deploying to Ethereum: write your contract in Solidity, compile it, connect your wallet to the target network (adding the correct RPC endpoint and chain ID), and deploy using Hardhat, Truffle, or Remix. Because QIE Blockchain supports the same tooling and languages as Ethereum, existing Solidity contracts can be deployed to QIE without rewriting them.
QIE Blockchain runs a Developer Grant Program offering funding from 5,000 to 500,000 QIE depending on a project's scope and impact, alongside mentorship and development resources, for teams building on the QIE network.
