The Scale Problem
“Managing spend for 5 agents is a settings page.
Managing spend for 500 agents is an operations problem.

The agent economy isn't coming. It's here. Budget allocation, per-agent rules, instant revocation, real-time monitoring — this is infrastructure, not a feature.

01
One Wallet
All agents spend from your existing wallet. No new wallets, no new keys.
02
Unlimited Agents
Each gets its own credential with independent daily limits.
03
Instant Revocation
Kill any agent immediately. Compromise is always capped.
04
Mission Control
See every agent, every limit, every payment in one place.
The Problem

Agents need money.
The tools to give it safely didn't exist.

Without PaySpawn
With PaySpawn

Private key lives in .env file

One breach = wallet drained. No limits, no recovery.

Agent holds a credential string

Compromised credential can only spend within your preset limits. Not your keys, not your wallet.

x402 needs agents to have their own wallets

Key management per-agent. Fund each one separately. One gets compromised, it's gone.

One wallet rides any x402 rail

Credential delegates from your wallet. Agent pays any x402-enabled API — no owned wallet needed.

Managing 100 agents is a spreadsheet

Which agent spent what? Who has access? No visibility, no control at scale.

Mission Control — fleet management built in

Every agent, every limit, every transaction in one dashboard. Revoke any agent instantly.

Custodial service holds your keys

Trust a third party. Hope they don't get hacked or go offline.

Non-custodial. You keep your keys.

Limits enforced by smart contract. We can't move your money. The chain enforces the rules.

Agents need ETH for gas

Fund two tokens per agent. Monitor two balances. Agent stops when gas runs out mid-task.

Agent only needs USDC

Our relayer covers gas. One token, zero headaches. $0.005 per transaction.

Sending to 0x4eB1b8Dd6eccBE4fE...

Off by one character = funds gone forever. Every payment is a risk.

Send to alice.pay

Human-readable .pay names on-chain. Agents paying agents — readable, verifiable, permanent.

x402 ProtocolNative

Every API on the internet
is about to have a price.

HTTP 402 has been dormant for 30 years. x402 brings it back: API returns a price → agent pays USDC → gets access. No accounts, no API keys, no billing cycles. Stripe launched it. Coinbase built for it. The standards war is happening now.

x402 tells agents how to pay. It doesn't tell you who controls how much they spend. PaySpawn is the wallet layer — the fleet credential that lets any agent ride any x402 rail, within your limits, without owning a single private key.

“x402 is the payment rail. PaySpawn is the wallet your agent uses to ride it.”

Send — Agent pays x402 APIs

Your agent hits a 402 API → PaySpawn handles the payment automatically, within your spending limits

POST /api/x402 → payment settled, access granted
Receive — Accept x402 for your APIs

Gate your own services behind x402 — PaySpawn is the full facilitator stack

How it works

One wallet.
Unlimited agents.

Each agent gets its own credential with its own daily limit, all delegating from one wallet you already have. No new wallets, no new keys, no new risk.

01

Connect your wallet

Any wallet. MetaMask, Coinbase, Smart Wallet. Your keys never leave your device.

02

Create agent credentials

One per agent — each with independent daily limits. 3 agents or 300, same flow.

03

Deploy and ride the x402 rail

Paste the credential string. Agent calls our API or SDK to pay any x402 API, on-chain, within your limits.

Integration

One line.

Credential string in env. SDK call to pay. Agent sends USDC to any wallet, .pay name, or x402 API — on-chain in ~2 seconds. No private keys. No ETH. No complexity.

No private keys for agents
Pay wallets, .pay names, or x402 APIs

$0.005 per transaction
// agent.js
import { PaySpawn } from '@payspawn/sdk'

const ps = new PaySpawn(
  process.env.PAYSPAWN_CREDENTIAL
)

// pay a .pay name
await ps.pay('alice.pay', 5.00)

// call any x402 API — payment handled automatically
await ps.fetch('https://api.example.com/data')
Name System

Agents paying agents.
Human-readable.

When agent-to-agent commerce becomes real — and it's coming fast — hex addresses aren't an identity layer. .pay names are. Registered on-chain on Base. Resolved anywhere PaySpawn is accepted.

alice.pay sends to research-bot.pay. On-chain. Verifiable. No typos, no hex, no fear.

The Landscape

Every option in one place.
Why PaySpawn is different.

There are now a dozen products claiming to solve agent payments. Most solve wallets — where money lives. PaySpawn solves control — how it moves. These are different problems.

PrivyKey Management

Custodial wallet-as-a-service. They manage keys on your behalf via secure enclaves.

The gap

Custodial — Privy holds the keys. Software-enforced limits. If their servers go down, your controls go with them. Enterprise pricing ($5K+/mo).

SpongeYC W26 · Agent Payments

Financial infrastructure for agents. Bank accounts + crypto. x402 support. MCP integration. Fund once, agents spend autonomously.

The gap

Built on Privy — same custodial model, same server dependency. Software spending limits. No on-chain enforcement. No fleet provisioning or counterparty whitelists.

Coinbase AgentKitAgent Wallets

Agents create and own their own wallets. Full autonomy — agents hold their own keys and sign their own transactions.

The gap

The agent IS the wallet owner. No delegation, no spending limits, no revocation. A compromised agent has full control of its funds with nothing to stop it.

TurnkeyMPC / TEE Key Infra

Hardware-backed key management via Trusted Execution Environments. Sub-100ms signing. Multi-chain. Policy engine with granular controls.

The gap

Software-enforced policies — enforcement lives in their TEE servers. No on-chain limits. Enterprise-grade complexity and pricing. Clients include Polymarket, Axiom.

MetaMask ERC-7710Wallet Delegation

Wallet-native delegation with spending constraints baked into MetaMask. Set limits directly inside the wallet UI.

The gap

Enforcement lives in the MetaMask client. Switch wallets = controls gone. Only works if the agent uses MetaMask. No fleet management, no batch provisioning.

MoonPay AgentsFiat Onramp + Swaps

Fiat-to-crypto onramp and swap rails for agents. x402 compatible. npm install CLI. Agents can fund wallets and execute swaps.

The gap

Payment rails only — no spending limits, no caps, no revocation. Gets money IN, but nothing controls how it goes OUT. Complementary to PaySpawn, not competing.

Safe (Gnosis)Multisig + Modules

Programmable multisig wallet with spending limit modules. On-chain rules enforced by the Safe contract. Industry standard for DAO treasuries.

The gap

Requires migrating to a Safe wallet. Complex multisig setup. Not designed for AI agent delegation. No fleet provisioning. High setup friction — days, not minutes.

Only PaySpawn

Capabilities no other solution offers.

The others solve wallets and key management. PaySpawn solves the layer above — what the agent is allowed to do with the money it can access. That's a different problem.

Contract-Level Enforcement
Limits live in the PaySpawn smart contract on Base. No server. No software. No company needs to be running. The blockchain enforces it.
Wallet-Agnostic
Keep MetaMask, Coinbase Wallet, Ledger, Safe — whatever you have. PaySpawn is a permission layer on top of any wallet. No migration. Sign once.
Budget Pools + Fleet Provisioning
One pool of capital. Unlimited agents. Each gets their own credential with independent daily + per-tx limits. Provision 50 agents in a single transaction.
Counterparty Whitelist
Lock an agent to only pay specific contract addresses. An agent running a DeFi strategy can only interact with Uniswap — nowhere else. Enforced by math.
Signed Receipts + Webhook Dispatch
Every payment generates a cryptographically signed receipt. Other agents can verify they received payment before completing work. Agent-to-agent trust without intermediaries.
On-Chain Pause
Instantly suspend any credential with one transaction. Not 'revoke access on our servers' — it's on-chain, immediate, and verifiable by anyone on Basescan.
5-Minute Setup, Zero Enterprise Sales
npm install, generate credential, done. No Privy onboarding, no Turnkey enterprise contract, no Safe multisig migration. Works with what you have today.

MoonPay gets money in.
Sponge lets agents spend it.
Coinbase gives agents their own wallet.
PaySpawn controls how it moves — and the math enforces it.

These aren't competitors. They're different layers of the same stack. PaySpawn is the control layer. It works on top of all of them.
