Ecosystem

Plug in what you already run

Paxeer X speaks the payment and agent protocols your software already uses, bridges to nine chains, and works with the wallets, runtimes and tools builders reach for first.

Nothing here asks you to learn a new protocol. Each adapter turns a request your stack already makes into a payment the user signed and a receipt anyone can check.

Six protocols, one network

A seller charging per request, a checkout waiting on a payment, an assistant that needs a wallet. Each arrives through a protocol it already knows and leaves with a signed receipt.

x402
Charge for an HTTP route. Your server answers 402 with a price, the agent pays, the request goes through. No facilitator holds the money and no card is on file.
Open
AP2
Accept an agent's payment mandate, check it against what its owner allowed, then execute the payment it permits and nothing more.
Open
UCP
Complete a commerce checkout only once a verified receipt says the money moved. Carts, orders and fulfilment stay in your stack.
Open
Visa TAP
Verify a trusted-agent intent and settle it as a payment the user signed, so an agent can shop where cards are accepted today.
Open
MCP
Give Claude Code, Claude Desktop, Cursor or VS Code a wallet, payments and receipts as tools, held to limits you set. Thirty-six tools, one install command.
Open
A2A
Run a payment-capable agent-to-agent server so other agents can hire yours, pay it, and check the receipt themselves.

Bring funds from nine chains

Lock PAX on any of these chains and it is released on Paxeer X once independent attestors agree; send it back the same way. SID moves between Paxeer X and Solana, its other home.

Treasury on Ethereum, agents on Paxeer X: a transfer in, a month of per-request payments, a transfer out, each step with its own receipt.

How the bridge works
  • EthereumPAX
  • BasePAX
  • ArbitrumPAX
  • OptimismPAX
  • BNB ChainPAX
  • PolygonPAX
  • AvalanchePAX
  • HyperEVMPAX
  • SolanaPAX and SID

Works with the runtimes you build agents in

Install the MCP server and any of these can hold PAX, pay for a tool and hand you the receipt, within the limits you set.

Around the chain

Where to hold PAX, where to look things up, and where to check that everything is running.

PaxPort
The Paxeer X wallet. Sign in with email, Google or a passkey; your key is split across independent signers and recoverable if you lose a device.
Open
MetaMask and any EVM wallet
Add chain 125 with the standard parameters and you are in. Rabby, Rainbow, Ledger and the rest work the same way.
