Send by @handle

Type a username instead of a 36-character address. xchng resolves handles instantly — no copying, no pasting, no mistakes.

Address-based transfers

Every account gets a unique vp1_ wallet address. Share it with anyone to receive funds — no personal details exposed.

Stripe bank linking

Connect your bank securely via Stripe Financial Connections. Your credentials never touch xchng's servers — Stripe handles the entire authentication flow.

Stripe Connect payouts

Set up a Stripe Express account to withdraw your wallet balance directly to your bank. Supports both individual and business accounts.

QR code payments

Generate a branded QR code for your wallet address. Recipients scan it to send instantly — works in person or shared over a message.

4-digit transaction PIN

Every send, deposit, and withdrawal requires your personal PIN. Stored as a SHA-256 hash on your device — never transmitted to any server.

Full transaction ledger

Every credit and debit is recorded with timestamp, amount, and counterparty. A clean, tamper-evident audit trail — synced to our server ledger in real time.

Multi-bank support

Link multiple bank accounts and choose which one to draw from on each deposit. Unlink accounts at any time with a single tap.

Agent Commerce

Your wallet, on autopilot.

Register autonomous spending agents with granular policy controls. Agents can transact within your defined limits — no human approval required below the threshold you set.

  • Granular policy controls Cap each agent by transaction size, daily total, and the specific wallet addresses it can send to.
  • Approval thresholds Set a dollar threshold below which the agent auto-approves. Above it, the transaction routes to you for manual confirmation.
  • Full audit trail Every agent action — approved, rejected, or circuit-broken — is logged with timestamp, amount, and outcome.
  • Freeze and resume Suspend any agent instantly without deleting it. Resume when ready — policy and history are preserved.
  • API key authentication Each agent gets a unique API key. Integrate with your own systems or AI workflows to trigger transactions programmatically.

How it works

Up and running in minutes.

01

Create your wallet

Enter your name, choose a @handle, and verify your email. xchng generates a unique vp1_ address instantly. No KYC, no waiting.

02

Link a bank

Connect via Stripe Financial Connections. xchng only reads your balance to verify funds — no credentials stored, no recurring access.

03

Send by handle or address

Type @username to find anyone on the network, or paste a vp1_ address. Authorize with your PIN — done in seconds.

Security by design

Your credentials never leave Stripe.

xchng is built on the principle that a payments platform should never need more access than the transaction requires.

  • Zero credential storage Bank login credentials go directly to Stripe's hosted UI. xchng receives only a tokenized account reference — never your login details.
  • 4-digit transaction PIN Every send, deposit, and withdrawal is gated behind your PIN, stored as a SHA-256 hash on your own device — never transmitted or logged.
  • Agent policy enforcement Agents operate within strict limits you define. Transactions exceeding your threshold require your explicit approval before they execute.
  • Address-only transfers Sending requires only a wallet address or @handle — never a name, phone, or account number. You control what you share.
  • Server-backed ledger Balances are reconciled against a Firestore ledger with atomic transfers — ensuring debits and credits are always consistent across devices.
