Create request
The merchant creates a QR payment or a secure remote payment link.
NexaChain Web
The modern payment network for stablecoins.
Accept payments in person or remotely using QR codes and secure payment links. Built for self-custodied wallets and direct blockchain settlement.
How it works
One payment network. Two ways to pay.
NexaChain supports both in-person QR payments and remote payment links while preserving the same user-authorized settlement flow.
Share or display
The request is displayed as a QR code or shared through email, WhatsApp, or another app.
Review payment
The buyer reviews the merchant, amount, service fee, token, and network.
Authorize
The buyer signs the transaction locally using their self-custodied wallet.
Settle on-chain
The blockchain confirms the payment and funds are delivered directly.
NexaChain ecosystem
Infrastructure for local and remote stablecoin commerce.
Merchant tools, buyer authorization, payment links, and direct blockchain settlement operate as one connected system.

◇
Self-custodied wallets
Private keys remain on the user’s device and transactions require explicit approval.
◎
Direct settlement
Payments are submitted directly to the blockchain without NexaChain holding user funds.
≋
Transparent pricing
Payment details, the 2% software service fee, and network requirements are shown before authorization.
Security by design
User control remains at the center of every transaction.
NexaChain is designed as a non-custodial software interface. Users retain control of their wallets, review transaction details, and authorize payments locally.
Core principle
NexaChain helps users create, review, and submit payment instructions. It does not take custody of customer funds.
Keys stay with the user
Private keys and recovery phrases are generated and stored on the user’s device. NexaChain does not receive, store, or control them.
Every payment requires approval
The buyer reviews the merchant, amount, token, fee, and network before authorizing the transaction.
Direct blockchain settlement
Signed transactions are submitted directly to the blockchain through the network RPC infrastructure.
No centralized custody
NexaChain does not maintain a pooled customer balance or centralized vault containing user funds.
