Live
Payment Links
Shareable links with a fixed amount, token, network, and expiry. Payers connect a wallet or scan the checkout QR. Create from the portal or POST /api/v1/payment-links.
PayAgent is Live
Non-custodial crypto payments for humans and AI agents. Payment links, invoices, profile pay, and a live merchant API on Ethereum, Base, and Solana. Built by LCX AI Labs.
Every AI agent will need a wallet, payment rails, and financial autonomy. PayAgent is how they pay.
What is PayAgent
PayAgent by LCX (Liberty Crypto Exchange) is crypto payment infrastructure for humans and AI agents. Merchants create links and invoices. Agents register via API, follow a spend policy, pay on-chain from their own wallet, and report the hash. PayAgent verifies the transfer before it is recorded.
Non-custodial. No private keys stored. No cut of the payment amount. The sender pays network gas. USDT and USDC are first-class on Ethereum, Base, and Solana.

What is Live
Live
Profile Pay
Receive any amount at /{username}. Same non-custodial checkout as links. Agents can pay a profile by username.
New
Invoices
Line items, PDF export, email share, and an optional attached payment link. Portal and POST /api/v1/invoices.
New
Ethereum, Base, and Solana
Checkout on Ethereum, Base, and Solana. USDC and USDT on all three. ETH on EVM, SOL on Solana, LCX on Ethereum.
Live
Non-custodial Settlement
PayAgent never holds keys and never broadcasts. The payer or agent signs in their own wallet. We record the payment only after the on-chain transfer is verified. No cut of the amount. Gas is paid by the sender.
New
Merchant Agent API
Register an agent, attach a wallet, preflight, then POST /api/v1/pay with txHash. Pay a link, profile, or raw address. OpenAPI at /api/v1/openapi.json.
New
Spend Policies
Fail-closed compliance: per-payment and daily/monthly caps, network and token allowlists, human approval above a threshold. No active policy means no pay.
Live
Verified Wallets
Merchants verify a receiving wallet per network with a signed message. Agent payer addresses are registered separately. Keys stay with the wallet.
Live
Webhooks
HMAC-signed events for link created, paid, and expired, profile pay, agent pay, and compliance approvals. Test deliveries from the portal or API.
Live
Transactions and Activity
Confirmed on-chain payments land in the workspace activity and transactions views as they settle.
New
Public Agent Leaderboard
Any API-registered agent with a confirmed txHash ranks on /leaderboard by volume. Filter by network. No private allowlist.
New
WDK protocol on npm
npm install @payagent/wdk-protocol. Pass a Tether WDK WalletAccount. The module preflights, sends, and records txHash. PayAgent never holds the seed. Docs: Docs v2.
New
Solana WDK test agents
Two dummy agents hop USDT on Solana mainnet through WDK. Register, attach networkId: solana, no-approval USDT policy, then pay. Step-by-step in Docs v2.
Live
Rewards and Referrals
Rewards default to USDT or USDC on confirmed payments. LCX is an optional extra, never required to send or receive. Referral credits still apply at sign-up. Rewards are not a checkout fee.

What is Coming

Mandates and Auto-Pay
Link an agent once, set a mandate, and let it pay later without a new browser popup each time. Built in product, not launched yet.
Planned
USAT and XAUT
Add Tether’s USAT and XAUT to checkout, invoices, and agent policies after official chain and contract addresses.
Planned
QVAC plugin
A QVAC / Bare plugin that calls the published @payagent/wdk-protocol module. The npm package is out; the QVAC catalog listing is next.
Planned
More Networks
Further EVM chains such as Arbitrum, plus Liberty Chain when settlement is ready. Base and Solana are already live.
Planned
ChatGPT plugin
Uploadable ChatGPT plugin plus hosted MCP at https://www.payagent.co/mcp. Opens PayAgent checkout and merchant/agent tools. ChatGPT does not hold keys or send the chain tx. Personal / workspace only until Legal clears a public listing.
Planned
Agent Framework Plugins
Drop-in tools for other agent runtimes so they can open a PayAgent checkout or record a hash from the environment they already use.
Planned
Deeper Payment Analytics
Richer filters, export, and reporting on top of the live transactions and activity feeds.
The opportunity
The Opportunity
There will be 10 billion AI agents by 2030. Every one of them needs to pay and get paid. PayAgent is building the financial infrastructure for autonomous commerce.
Today, no one owns this space. Stripe is not crypto-native. Existing crypto wallets are not built for agents. PayAgent is purpose-built for a world where both humans and autonomous software transact value on the same rails.
