One Protocol. Any Wallet.
Verifiable Settlement.
The open interoperability protocol that lets any merchant accept payments from any app — through one integration.
The Problem
Payments are fragmented. Every merchant integration is a new silo.
Payment Silos
Each payment provider requires separate integration, approval, and maintenance.
Automated Vendor Hell
Getting Automated vending machines to work across several jurisdictions is a nightmare .
Border Barriers
Traders can't pay local vendors. Cross-border settlements are complex and expensive.
Closed Systems
Users are locked out if they use the "wrong" wallet. No interoperability.
The Solution
OpenCharge Network: An open protocol for payment interoperability.
Single Integration
One protocol routes dozens of payment providers integrations.
Any Wallet Works
Users pay with their preferred app. No more "we don't accept that."
Verifiable Settlement
Payments can be verified off-chain, regardless of the payment app used.
DAO Governed
Protocol upgrades decided by stakeholders, not a single company.
Today
- Integrate with all 5-10 payment APIs separately
- Negotiate with each provider individually
- Users rejected if their wallet isn't supported
With OpenCharge
- One integration accepts all compliant apps
- Join the network permissionlessly
- Any OpenCharge compliant app works everywhere
How It Works
Simple example. Trustless settlement. Universal acceptance.
User Wants to pay
Merchant publishes protocol config via nft metadata
Users App makes Payment
Payment app collects via local method (MoMo, card, etc.)
On-Chain Settlement
Users app settles USDT/USDC to the protocol smart contract
Merchant App verifies
Merchant app verifies the payment on-chain, releases goods/service
Key Principle
The protocol decouples "who collects the money" from "who receives the money." The merchant app never trusts the payment app. They trust the blockchain settlement.
Edge Use Cases are baked in
Anywhere a merchant needs to accept auto-payments from diverse sources.
Why go to the extreme?
- — they can't fall back on cash or manual workarounds.
- — Integration cost is highest relative to revenue
- — Clear ROI: "plug in and start earning" vs. "hire a dev team"
- — Hardware manufacturers are motivated partners
