Agentic commerce on XDC · x402

Payment rails for AI agents.

Give any agent a non-custodial smart wallet and let it pay for APIs per call in USDC - within an on-chain spending limit you control. No gas, no seed phrase, no credit card. Built on the open x402 standard, settled on XDC.

How it works

From setup to paid API call in four steps

One-time setup, gas sponsored, no contracts. Then the agent drives the whole loop.

1
Set up your account
One signature creates your own non-custodial smart wallet with a spending limit you set - gas is sponsored.
2
Fund with USDC
Deposit USDC to your smart wallet address. That's the only balance an agent ever needs.
3
Connect an agent
Add the MCP connector in Claude/ChatGPT, or run the CLI in terminal agents - one time.
4
Call & pay
The agent pays per call from your wallet, capped on-chain - the x402 loop runs itself.

Funding

Two ways to fund the wallet

The agent spends USDC. Top it up directly, or put your XDC to work as collateral and borrow against it - without selling.

Deposit USDC

Send USDC straight to the wallet address shown at login. It's the only balance an agent needs - gas is sponsored, so no native XDC required.

Any wallet or exchange that supports USDC on XDC
Spendable immediately, metered per call

Coming soon

Borrow against XDC

Hold XDC and don't want to sell? Lock it as collateral on an XDC lending market and borrow USDC to fund the agent - keeping your XDC exposure while it spends.

Collateralize XDC → borrow USDC
Stay long XDC while your agent transacts in stablecoins

Use cases

Anything an agent can pay for, in stablecoins

XDC AI is the rails - builders ship the services. Each one is just an x402 endpoint, paid in USDC, gasless, per call.

Paid in USDC · gasless · per call

Send & receive

Move USDC to any address in a single call - agent-to-agent or agent-to-human payouts.

Swap stablecoins

Swap between stablecoins and tokens on XDC, priced and settled per request.

Book a hotel

Reserve a room and pay on confirmation - travel checkout an agent can complete end to end.

Book flights

Search fares and ticket a flight, paying the exact amount in USDC at purchase.

Order pizza

Real-world commerce: place an order and pay at checkout - food to your door, agent-driven.

Build your own

Wrap any API in x402 and name your price. If an agent can call it, it can pay for it.

Use it in your LLM

Add XDC AI to Claude, ChatGPT, or your terminal

Two ways in: connect the MCP server in chat apps, or run the CLI in terminal agents. Then just ask, in plain language.

Chat apps

Claude.ai · ChatGPT

no terminal

Add one custom MCP connector in Settings → Connectors. It runs the wallet and payments server-side, so the chat app can log in, check balance, and pay - just by asking.

Setup for Claude.ai & ChatGPT

Terminal agents

Claude Code · Cursor · Codex · Hermes

Run the CLI and let the agent drive it. One JSON object per command, gasless payment on every 402 - nothing else to wire up.

DeFi partners

Put idle USDC to work across XDC DeFi

Supply, withdraw, borrow, and repay on integrated protocols - human-approved, executed by your smart wallet.

Why XDC AI

The missing wallet and checkout for autonomous agents

Gasless by default

Payments use EIP-3009 transferWithAuthorization: the agent signs off-chain and a relayer pays the XDC gas. Agents only ever spend USDC - never native gas.

Non-custodial by design

You own a smart wallet (Safe) with an on-chain spending limit your agents can never exceed. The platform holds no keys to your funds, and you can revoke access any time.

Pay exactly per call

Each request settles the exact USDC price on-chain - no subscriptions, no invoices, no minimums. Metered, programmatic spend that an agent can reason about.

Built right

Everything an agent needs to transact safely

Agent-native output

Exactly one JSON object per command on stdout, structured errors on failure - any LLM can parse and act on the result.

MCP & SKILL.md

Ships a skill manifest and MCP discovery tools so Claude, Codex and other agents drive it autonomously.

Open x402 standard

Speaks x402 exact-evm - works with any compliant facilitator or resource server, not a walled garden.

Swappable wallet

Ports & adapters: move from HD to MPC to smart accounts or a 3rd-party custodian with zero caller changes.

Settled on XDC

Fast, low-cost finality with USDC (Circle FiatTokenV2). Real on-chain transfers, with an explorer link per call.

Two-sided

Providers wrap any API in middleware to earn USDC per call and get discovered by paying agents.

For agents & developers

Ship an agent that pays its own way

A non-custodial smart wallet with an on-chain spending cap agents can't exceed
Works from chat apps (MCP) and terminal agents (CLI)
One JSON object per command, SKILL.md + MCP so agents self-drive

Set up your account

For API providers

Turn any API into per-call USDC revenue

Wrap any existing API - no code changes, return 402, get paid
Receive USDC to your address; a relayer pays the gas
Get discovered by paying agents in the marketplace

List your service

Get started

Two ways in

Set up your account to pay for services, or list your own service to get paid. Both take one signature - gas is sponsored.
