Rozo Cross-Chain Payments / Bridging

Send cross-chain crypto payments and bridging via Rozo. Send USDC/USDT across Ethereum, Arbitrum, Base, BNB Chain (BSC), Polygon, Solana, and Stellar (Base and Stellar are USDC-only; Solana receives USDC only but can pay in USDT).

Confirmation: every payment, any amount, shows full details and waits for an explicit yes/no. Small-amount auto-execute exists but ships OFF (thresholds 0 in version.json); it runs only if the user raises them.

Routing

Determine the user's intent and load the matching sub-skill:

Intent	Sub-skill	Triggers
Send a payment	skills/send-payment/SKILL.md	"pay", "send", "transfer", "payout", shares a QR code, provides an amount + address
Check wallet balance	skills/check-balance/SKILL.md	"check balance", "how much do I have", "show my balance", "wallet balance"
Parse a QR code	skills/parse-qr/SKILL.md	"scan QR", "parse QR", "read this QR", shares a QR image without mentioning payment
Check payment status	skills/payment-status/SKILL.md	"check payment", "payment status", "where is my payment", "track payment", provides a payment UUID or tx hash

Rules:

1. If the user mentions sending/paying → route to send-payment (it handles QR parsing internally)
2. If the user shares a QR code WITHOUT mentioning payment → route to parse-qr first, then offer to send
3. If the user asks about balance before sending → route to check-balance, then continue to send-payment if they want to pay
4. If ambiguous, ask the user what they'd like to do

Supported Chains

Pay-Out (sending to)

Chain	USDC	USDT
Ethereum	Yes	Yes
Arbitrum	Yes	Yes
Base	Yes	No
BSC	Yes	Yes
Polygon	Yes	Yes
Solana	Yes	No
Stellar	Yes	No

Pay-In (paying from)

Base	Yes	No
BSC	Yes	Yes
Polygon	Yes	Yes
Solana	Yes	Yes
Stellar	Yes	No

Trust the live API over these tables. Do NOT refuse a user's request based purely on the tables above. Tables can be stale or misread — always call create-payment.js --dryrun first and let the API be the source of truth. If dryrun returns success: true, the route is supported; if it returns an error, report that error to the user. Never tell a user "this route isn't supported" without running the dryrun first.

Runtime

Requires Node.js (ES modules). All scripts in scripts/dist/ are run with node.

Authentication & Rate Limiting

The Rozo APIs are public and rate-limited — no API keys or authentication tokens are required.

Endpoint	Host	Auth	Notes
Payment API (create, get, check)	intentapiv4.rozo.ai	None (rate-limited)	Main Rozo payment API
Balance API (check balance)	api-balance.rozo-deeplink.workers.dev	None (rate-limited)	Rozo balance service (Cloudflare Workers)

Both hosts are operated by Rozo. The balance endpoint uses a separate Cloudflare Workers deployment for performance.

Data sent to Rozo: as part of normal operation, wallet addresses, chain/token choices, amounts, memos, and payment IDs are transmitted to Rozo's public rate-limited APIs (intentapiv4.rozo.ai, api-balance.rozo-deeplink.workers.dev). No API key is involved. Anyone who can observe a payment ID can query that payment's status.

Quick Reference

• Amount limits: $0.01 minimum, $10,000 maximum per transaction
• Token selection: Auto — fetch balance, prefer USDC, fall back to USDT
• Payment type: exactOut by default — recipient gets exact amount, fee added on top

Scripts

Shared Node.js scripts in scripts/dist/ (run with plain node):

Script	Purpose
check-balance.js	Fetch wallet balances via Rozo balance API
check-stellar-trustline.js	Verify asset trustline (USDC/EURC) on Stellar G-wallets
create-payment.js	Create a payment (or dryrun for fee estimate) via Rozo API
get-payment.js	Get payment status by ID, tx hash, or address+memo
parse-qr.js	Parse payment QR code URIs (EIP-681, Solana Pay, Stellar URI)
chains.js	Shared chain/token config (imported by other scripts)
