A New Model for Digital Dollar Payments
Stablecoin innovation is expanding beyond traditional fiat-backed models. As digital commerce evolves, new forms of dollar-denominated assets are emerging, designed for scalability, programmability, and on-chain-native infrastructure.
USDe by Ethena on WalletConnect Pay brings this next-generation digital dollar to checkout.
This article explains:
- What USDe is
- How it differs from traditional stablecoins
- How WalletConnect Pay enables USDe payments
- What this means for merchants and PSPs
What Is USDe?
USDe is a synthetic dollar protocol developed by Ethena. It is designed to maintain a stable value relative to the US dollar, but unlike fiat-backed stablecoins, it uses crypto-native collateral and hedging mechanisms.
USDe is:
- Dollar-denominated
- Designed for onchain environments
- Integrated across DeFi and wallet ecosystems
- Structured to operate independently of traditional banking rails
It represents a different approach to digital dollars, one built entirely within blockchain infrastructure.
Why Synthetic Dollars Matter in Payments
As blockchain ecosystems mature, not all dollar-denominated assets follow the same model.
Fiat-backed stablecoins prioritize:
- Bank reserves
- Regulatory reporting
- Offchain custody frameworks
Synthetic dollars like USDe prioritize:
- Onchain-native collateral
- Crypto-based stabilization mechanisms
- Integration across decentralized financial systems
For wallet-native consumers and onchain economies, this creates additional flexibility in how value moves and settles.
Bringing USDe to Checkout with WalletConnect Pay
WalletConnect Pay enables merchants to accept wallet-based payments across a wide range of supported digital assets, including USDe.
The model remains consistent:
- The customer selects “Pay with Wallet” at checkout.
- A WalletConnect QR code or deep link appears.
- The customer confirms the transaction in their wallet.
- USDe is transferred onchain.
- The merchant receives confirmation and settlement.
From a merchant perspective, the experience is seamless and consistent, regardless of the underlying asset.
WalletConnect Pay abstracts the complexity of wallet connectivity and multi-chain interactions into a structured, merchant-grade checkout flow.
Multi-Wallet, Multi-Chain Support
USDe operates within Ethereum-based ecosystems and compatible networks.
WalletConnect Pay supports:
- Multi-wallet interoperability
- Wallet-agnostic checkout
- QR-based and deep-link payments
- Integration across e-commerce and POS environments
Consumers can pay using the wallet they already use.
Merchants integrate once and access the broader wallet ecosystem.
USDe is particularly relevant in:
Onchain-Native Marketplaces
Platforms operating within Web3 ecosystems where synthetic dollars are already widely used.
DeFi-Integrated Commerce
Services and digital platforms that operate adjacent to decentralized finance infrastructure.
Global Digital Services
Online platforms that prioritize blockchain-native settlement.
WalletConnect Pay does not require merchants to specialize in crypto mechanics. It provides a standardized payment layer, while asset selection remains configurable at the integration level.
Synthetic Dollars vs Fiat-Backed Stablecoins
It’s important to distinguish between models.

WalletConnect Pay supports diverse digital assets to ensure interoperability across the wallet ecosystem, allowing merchants to align with the assets most relevant to their customers.
Infrastructure That Supports Choice
The evolution of digital payments is not one-size-fits-all.
Some merchants prioritize regulated fiat-backed stablecoins like USDC.
Others serve on-chain-native communities where assets like USDe are prevalent.
WalletConnect Pay provides:
- A universal wallet connection layer
- PSP-ready integration
- Structured checkout flows
- Compatibility with terminal and e-commerce environments
The goal is not to prescribe a single digital dollar model, but to enable interoperable commerce across them.
Expanding Payment Optionality
Digital payments are diversifying.
Alongside cards, open banking, and fiat-backed stablecoins, synthetic dollars represent another emerging category of programmable value.
USDe on WalletConnect Pay enables:
- Onchain settlement
- Wallet-based checkout
- Global accessibility
- Asset flexibility within merchant payment stacks
As digital commerce continues to globalize and decentralize, flexibility becomes infrastructure.
