BASE

Ethereum-compatible Layer 2

Fast for agents. Predictable for everyone.

Digital products need settlement that feels immediate without turning checkout into a fee auction. Base gives 0xRouter a fast, low-cost EVM execution environment with a clear receipt and finality policy.

Fast L2 feedback

ETH gas on Base

Receipt-driven delivery

Fast L2 feedback

Base provides fast L2 transaction feedback while 0xRouter waits for its configured receipt threshold.

Lower payment friction

L2 execution is typically low and stable, while ETH remains the gas token.

Receipt-based settlement

The app verifies the x402 settlement receipt and configured confirmations before releasing access.

WHY THIS CHAIN

The right defaults for agent-native commerce.

An AI agent should not need to wait through a slow confirmation loop or compete with a larger fee budget just to buy a small, clearly priced product.

Near-instant confirmations

Base is designed for fast L2 transaction feedback, keeping wallet flows responsive for everyday product purchases while the app enforces its settlement threshold.

Low-cost execution

Base executes on an Ethereum Layer 2. Gas is paid in ETH, and the final cost reflects L2 execution plus data posted to Ethereum.

Predictable ordering

0xRouter uses transaction receipts, contract logs, and a configured confirmation threshold instead of trusting a client-side payment response.

TRANSACTION FLOW

From signed payment to product access.

The fast path is designed for normal purchases. High-value or irreversible actions can use a stricter confirmation threshold before the app treats them as fully settled.

The wallet signs

The buyer or agent signs the requested payment with their own wallet policy.

Base settles

Base accepts and executes the transaction; 0xRouter waits for the configured receipt and finality threshold.

0xRouter delivers

The app verifies the receipt and configured confirmation level before releasing the license and content.

Fast does not mean careless.

Fast L2 feedback is the responsive everyday UX. The configured receipt and confirmation threshold is the checkpoint used for license delivery and high-value operations.

THREE BUILT-IN PROFILES

Local first. Base when you deploy.

The application keeps one chain-neutral EVM integration across local development, Base Sepolia, and Base mainnet. Only runtime network values, contracts, payment assets, and RPC endpoints change. See the full lineup on the supported networks page.

Local EVM

#31337

eip155:31337

Hardhat-compatible local testing with no external chain dependency.

Base Sepolia

#84532

eip155:84532

The x402 integration and contract verification target before a production network gate.

Base mainnet

#8453

eip155:8453

The production profile, selected through environment values after the Base Sepolia gate passes.

EVM-COMPATIBLE

Build with the tools you already know.

Base supports standard Ethereum tooling. 0xRouter uses Solidity contracts, viem, wagmi, and profile-aware RPC adapters so local, testnet, and mainnet use the same application boundary.
