Permissionless

zkStash is built on the core belief that AI agents should be autonomous economic actors that can operate, coordinate, and transact without human intervention.

Imagine a world where AI agents:

• Discover and use services independently, without waiting for human configuration
• Coordinate with other agents to solve complex tasks
• Pay for the resources they consume using their own wallets
• Persist knowledge across sessions, building expertise over time

This is only possible with permissionless infrastructure.

What do we mean by Permissionless?

In the context of zkStash, “permissionless” means:

1. Trustless Access: Agents authenticate with cryptographic wallet signatures—no registration, no API keys, no central authority to grant permission.

2. Borderless Payments: Pay with crypto (USDC, SOL, ETH) from anywhere in the world. No banks, no credit cards, no payment processors required.

The Agentic Economy

We envision a future where fleets of agents interact with each other, sharing knowledge and paying for resources autonomously.

• Own Resources: Agents “own” their memories. The cryptographic identity that creates a memory is the only one that can update or delete it.
• Pay for Usage: Agents pay for their own storage and compute costs on a per-request basis or via pre-funded balances.

x402 Protocol

x402 is an open standard that brings payments into the HTTP request flow. It enables seamless, programmatic payments for internet resources.

Key Principles

• HTTP-Native: x402 seamlessly complements existing HTTP—no additional requests or special protocols required.
• Chain-Agnostic: Support for multiple blockchains (Solana, Base, and more). Agents choose what works best for them.
• Gasless: The facilitator (zkStash) handles gas fees, so agents only pay for the resource, not network overhead.
• Trust-Minimizing: Payments are cryptographically verified on-chain. Neither the facilitator nor the resource server can move funds without client authorization.

Supported Networks

• Solana: Ultra-fast, low-cost transactions
• Base: Coinbase L2, EVM-compatible

Why This Matters

• True Autonomy: Agents can operate indefinitely as long as they have funds in their wallet.
• Coordination at Scale: When agents can pay for their own resources, multi-agent systems become practical. Dynamic teams can form and dissolve automatically. Specialized agents can be created on-demand without human provisioning or central payment bottlenecks.
• Sybil Resistance: The cost of memory operations acts as a natural spam filter. Creating thousands of fake memories costs real money, preventing free tier abuse and keeping the system healthy through economic incentives.
• Global, Borderless Operation: Traditional payment systems require banks, credit cards, and compliance with geographic restrictions. x402 micropayments work anywhere.

The Vision

We’re building infrastructure for a future where millions of agents collaborate to solve problems too complex for single systems. Agents will fund themselves from their economic activity—like a trading bot that pays for memory from its profits. Human involvement will focus on high-level goals, not operational maintenance. Innovation will accelerate because agents can compose services without integration friction.

This is the agentic economy, and we are committed to making it a reality.
