Agentic Browser Documentation

The first agentic browser with built-in wallet and native x402 protocol support. Designed for the autonomous agent economy.

Introduction

Learn about x402 protocol, HTTP 402, and why agentic browsers need built-in wallets.

x402 Protocol

Deep dive into the technical specification of x402 payment channels and micropayments.

Architecture

Browser architecture, MPC wallets, threshold signatures, and security model.

Key Custody

Self-custody principles, distributed key generation, and why "not your keys, not your crypto" matters.

>< Tokenomics

Native payment token, cost-basis API pricing, strategic partnerships, and fair launch economics.

Integration Guide

Developer documentation for integrating x402 middleware and building agentic applications.

Quick Start

Get started with the Agentic Browser in three steps:

  1. Join the waitlist - Sign up for early access at Q4 2025 launch
  2. Connect your wallet - Phantom, Solflare, or any Solana-compatible wallet
  3. Configure agent spending - Set auto-approval limits and transaction thresholds

Why Agentic Browsers?

As autonomous AI agents become more prevalent, they need:

  • Self-custody of keys - Agents must manage private keys securely without exposing them to third parties
  • Micropayment capability - Pay fractions of a cent for API calls, content access, and compute resources
  • Spending controls - User-defined thresholds and auto-approval rules for autonomous transactions
  • x402 protocol support - Native HTTP 402 implementation for seamless machine-to-machine payments

Traditional browsers were designed for humans. Agentic browsers are designed for autonomous agents operating on behalf of users - while keeping users in full control of their keys and spending.

Quote from Andreas Antonopoulos:

"Your keys, your Bitcoin. Not your keys, not your Bitcoin."

This principle is fundamental to the Agentic Browser's architecture - users maintain full custody of their private keys, even when agents operate autonomously.

Technical Stack

  • x402 Protocol - HTTP 402 micropayment implementation (Coinbase standard)
  • MPC Wallets - Multi-party computation for distributed key management
  • Threshold Signatures - TSS/ECDSA for secure transaction signing
  • Solana Integration - Native SPL token support with sub-second finality
  • >< Token - ERC-20 utility token on Base (Solana launch via PumpFun)
  • Payment Channels - L2 micropayment infrastructure for high-frequency transactions
