# Welcome to Oceanum (OXN)

**Oceanum (OXN) is a confidential EVM Layer 1, secured by hardware-attested Trusted Execution Environments (Intel SGX).**

Deploy the Solidity contracts you already know — but with end-to-end confidentiality: encrypted contract state, encrypted transaction inputs, and encrypted logs. Confidentiality is enforced by real TEE hardware on every validator, not by trust assumptions or off-chain cryptography.

***

### **Why** Oceanum (OXN) <a href="#why-oxn" id="why-oxn"></a>

**Confidential by default.** Contract storage and calldata are encrypted. Only the contract itself can decrypt its own state. There is no separate "private mode" to opt into.

**Full EVM compatibility.** Deploy any Solidity contract. Use Hardhat, Foundry, ethers.js, viem, and MetaMask exactly as you do on Ethereum. Standard ERC-20 / ERC-721 / ERC-1155 work unchanged.

**Hardware-secured, not trust-secured.** Every validator executes contracts inside Intel SGX enclaves. Remote attestation cryptographically proves that your transaction runs in a genuine TEE — the node operator cannot see your state, and neither can we.

**Sovereign Layer 1.** Oceanum (OXN) runs its own consensus and validator set. It is not a rollup and does not depend on any other chain for finality or data availability.

### Network at a Glance <a href="#network-at-a-glance" id="network-at-a-glance"></a>

Oceanum (OXN) is currently available as a public testnet. Mainnet is on the roadmap.

Solidity compiler settings

Oceanum (OXN) currently targets the `paris` EVM version. If you use solc `0.8.20` or newer, set `evmVersion: "paris"` in your compiler config. See [EVM Compatibility](https://docs.bout.network/concepts/evm-compatibility) for the full opcode support matrix.
