Does Autheo support EVM-compatible smart contracts?

Autheo's EVM adapter is built and maintained by the core protocol team, ensuring compatibility is tested against every AEE runtime update.

Direct Answer

Yes. Autheo's Eigensphere Engine includes an EVM adapter layer that allows Solidity smart contracts to be compiled and deployed on Autheo with minimal changes. Existing Ethereum dApps can be ported to Autheo to benefit from higher throughput, lower fees, post-quantum security, and native AI — while retaining Solidity as the development language.

How EVM Compatibility Works on Autheo

The AEE's EVM adapter accepts Solidity contracts compiled to standard EVM bytecode and executes them within the Autheo runtime environment. From a developer perspective, standard Hardhat or Foundry workflows compile Solidity contracts as usual, and the Autheo CLI handles the translation layer for deployment. Most standard ERC-20, ERC-721, and DeFi contract patterns work without modification.

What Changes When Moving from Ethereum to Autheo

The primary differences are: (1) transaction fee denomination — THEO instead of ETH; (2) RPC endpoint — Autheo's validator RPC rather than Ethereum's; (3) gas model — Autheo's fee structure targets near-zero costs versus Ethereum's dynamic fee market; and (4) optional but available: access to Autheo-native features like AutheoID, THEO AI, and cross-chain routing that Ethereum contracts cannot natively access.

Migration Path for Existing Ethereum Projects

The Autheo DevHub provides a migration guide and toolchain for existing Ethereum projects. The standard path is: (1) compile your existing Solidity contracts; (2) update the network configuration in your deployment scripts; (3) deploy to Autheo testnet and verify; (4) optionally integrate Autheo-native features via SDK. Most ERC-standard contracts can complete this migration in under a day.

Key Statistics

~3,700

New Ethereum contracts deployed daily

Ethereum sees approximately 3,700 new smart contract deployments per day — representing a large developer base that Autheo's EVM compatibility targets for migration.

Estimated migration time for standard ERC contracts

Standard ERC-20 or ERC-721 contracts on Ethereum can typically be deployed to Autheo testnet within a single development day using the Autheo migration guide.

50x

Throughput improvement over Ethereum L1

Autheo's 1,500+ TPS capacity represents approximately 50x the throughput of Ethereum L1, reducing congestion risk for migrating applications.

Expert Perspective

“
EVM compatibility is the lingua franca of smart contract development. Any serious alternative network must speak Solidity if it wants to attract the existing developer base.
