Build on Autheo: Sovereign Developer Infrastructure
Autheo gives developers a complete infrastructure stack for building decentralized applications: integrated identity (TheoID), decentralized compute (decentralized compute through the Autheo Marketplace), persistent storage, a native development workspace (DevHub), and AI orchestration (THEO AI). Deploy smart contracts in Solidity, Move, Vyper, Rust, Go, or C using a single unified platform.

Build Without Limits
Autheo gives builders the power to:
- Launch secure, scalable projects and ecosystems
- Create with integrated infrastructure, not makeshift fixes
- Scale, evolve, and own what they build, without compromise
Build
Launch projects, ecosystems, and developer hubs on infrastructure designed for ownership, not dependency. Your logic. Your systems. Your pace.
Connect
Tap into a composable network of builders, assets, and protocols, where every connection strengthens the collective. Build wide. Move smart.
Own
Take full control of your code, data, distribution, community, content, branding, monetization and analytics. Autheo puts you in charge.
On Autheo, Every Stack Becomes a System
Whether you're launching a project, scaling an enterprise, or building an entire network, Autheo turns isolated stacks into living, connected systems.
Custom Projects
Protocols, apps, and dApps built with full backend, identity, and infrastructure integration.
Sovereign Marketplaces
Fully owned digital economies, DeFi systems, or tokenized platforms with control over distribution and value flows.
Integrated Networks
Interconnected ecosystems, DAOs, private networks, or industry consortiums that scale without fragmentation.
Developer Hubs
On-chain environments and toolkits for building, testing, and scaling applications across Web2 and Web3.
Enterprise Solutions
Permissioned networks, cross-chain integrations, and vertical-market deployments with compliance and scalability built in.
Seamless Integration
Applications and services with unified APIs, SDKs, and backend sync, interoperable by design, not by assembly.
Your Workflow in One Place
DevHub is where builders come to launch fast and grow without limits.
Generate your TheoID
A secure, private identity, yours to control.
Start a Project
Choose a template or start from scratch.
Join Your Builder Community
Connect with builders across the ecosystem.
Ask THEO AI
Describe what you want. THEO helps you build it.
Add What You Need
Wallets, DeFi logic, tokens, payments, permissions, storage, and more.
Set Up Your Workflow
Automate processes, connect agents, and orchestrate adaptive systems.
Test & Launch
Deploy your app, chain, or agent in one click with native compliance, compute, and identity.
Publish to the Marketplace
Share what you've built so others can use, buy, or remix it.
Earn & Grow
Monetize your build through usage, staking, or token logic, fully on-chain and trackable.
One Runtime, Six Languages
Autheo Chain is EVM-compatible, so any Solidity contract that runs on Ethereum runs on Autheo with no changes. Deploy with the same tools you already use, Remix, Hardhat, or Foundry, instead of retraining for a new chain-native syntax.
Solidity
EVM-compatible. Deploy existing Ethereum contracts with minimal changes and reuse familiar tooling, ABIs, and audit patterns.
Vyper
EVM-compatible, security-focused syntax with a smaller attack surface than Solidity for teams that want stricter language guarantees.
Rust
Memory-safe systems language for performance-sensitive contract logic and complex state machines.
Go
A familiar backend language for teams building services and contracts side by side without switching ecosystems.
Move
Resource-oriented language with built-in asset-safety guarantees, useful for token and asset-heavy applications.
C
Low-level control for deterministic, performance-critical routines that benefit from a systems-language implementation.
Every target language still needs its own compiler pipeline, test suite, and audit scope. Multi-language support means optionality, not a shortcut around review.
Inside the DevHub Workspace
DevHub is Autheo's native development workspace, live today, covering the full lifecycle from scaffolding to deployment in one place.
Create a project
Start from a language-specific template (Solidity, Vyper, Rust, Go, Move, or C) or import an existing repository.
Write and compile
Edit contract code in the workspace editor and compile against the EVM-compatible runtime target using standard Solidity tooling.
Run your test suite
Execute unit and integration tests directly in DevHub before touching testnet, catching failures early.
Deploy to testnet
Push a compiled build to Autheo testnet with one click, using faucet-funded THEO for gas.
Monitor and iterate
Track contract calls, gas usage, and errors from the workspace, then redeploy as you fix issues.
Promote to mainnet
When your test suite and manual review pass, deploy the same artifact to mainnet, where staking and transaction fees are live.
SDK and API Access
The Autheo SDK wraps contract deployment, calls, and account management behind a consistent API regardless of which language compiled the contract.
import { AutheoClient } from "@autheo/sdk";
const client = new AutheoClient({
network: "testnet",
rpcUrl: "https://testnet-rpc.autheo.com",
});
// Deploy a compiled Solidity contract (EVM bytecode)
const deployment = await client.contracts.deploy({
bytecode: compiledArtifact.bytecode,
abi: compiledArtifact.abi,
args: [ownerAddress],
});
console.log(deployment.address, deployment.txHash);
// Call a contract method
const result = await client.contracts.call({
address: deployment.address,
method: "balanceOf",
args: [ownerAddress],
});Deploy Solidity contracts using standard Ethereum tooling, Remix, Hardhat, or Foundry all work against Autheo Chain's EVM-compatible execution environment with no special configuration.
Gas Optimization Notes
Transaction fees are live on Autheo mainnet, so gas-aware design matters from day one, not as a later optimization pass.
- Batch state writes where possible. Each storage write costs more than in-memory computation, regardless of target language.
- Prefer fixed-size data structures over dynamically growing arrays in hot paths to keep gas costs predictable.
- Cache repeated external calls and reused values in local variables instead of re-reading contract state.
- Profile gas usage in DevHub before mainnet deployment. Fix expensive loops and redundant checks while iterating on testnet.
- For Rust, Go, and C targets, watch for unnecessary allocations inside contract entry points; they carry a gas cost like any other computation.
- Right-size event emissions. Logging is useful for indexers but adds cost, so emit only what downstream consumers actually need.
Testing Frameworks
Bring the testing tools your Ethereum stack already trusts. Autheo Chain's EVM compatibility means Hardhat and Foundry test suites work with no proprietary test runner required.
Solidity / Vyper
Use Foundry or Hardhat for unit tests, fuzzing, and gas snapshots against an EVM-compatible target.
Rust
Standard Rust unit and integration tests, plus property-based testing with proptest for contract invariants.
Go
Native Go testing package for unit tests, with table-driven tests for contract method coverage.
Move
Move's built-in unit test framework, useful for verifying resource-safety and asset-conservation invariants.
Cross-language
DevHub runs your project's test suite in CI before testnet deployment, regardless of source language.
Migrating From Ethereum
Autheo's runtime is EVM-compatible for Solidity and Vyper, so migration is usually a redeployment with verification, not a rewrite.
Inventory your contracts
List deployed contracts, external calls, privileged roles, and oracle dependencies before touching code.
Update RPC and tooling
Point your existing Hardhat or Foundry config at Autheo testnet RPC endpoints instead of an Ethereum node.
Redeploy through DevHub
Deploy the same Solidity or Vyper bytecode to Autheo testnet and confirm addresses, events, and ABI compatibility.
Re-verify gas assumptions
Gas costs differ by network. Re-run your gas profiling and adjust before promoting to mainnet.
