• Backing: Each eXRD is backed 1:1 by XRD held at a custodian
• Launch: November 2020 on Ethereum
• Swappable: 1:1 with XRD via Instabridge or Bitfinex
• Underlying network: Radix Public Network, a Layer 1 DeFi-focused blockchain
• Smart contract audited: Quantstamp security audit, November 2020

Introduction

e-RADIX (EXRD) is the wrapped Ethereum representation of XRD, the native token of the Radix Public Network. It is an ERC-20 token that allows XRD holders to access Ethereum's vast DeFi ecosystem without leaving the value of their Radix tokens behind.

Think of eXRD the way most crypto users think of wBTC: just as wrapped Bitcoin brings BTC into Ethereum DeFi, eXRD brings XRD into the same ecosystem — fully backed and always redeemable 1:1.

History & Background

Radix was founded by Dan Hughes, a UK-based developer who discovered Bitcoin in 2012. After years of research, Hughes and his team built the Radix protocol with one specific goal: to become the first Layer 1 specifically designed to serve decentralized finance (DeFi).

eXRD was launched in November 2020 as an ERC-20 token on Ethereum. It was issued prior to XRD going live on the Radix mainnet, serving as an early mechanism for distributing tokens widely before staking began on the Radix network.

How e-RADIX Works

eXRD is created when XRD is deposited with a secure third-party custodian. An equivalent amount of eXRD is then minted on Ethereum, maintaining a strict 1:1 peg with the underlying XRD.

Users can swap eXRD back to XRD at any time — there is no expiry or cutoff for this conversion. The swap can be performed via Instabridge, Hyperlane, or through exchanges such as Bitfinex. Arbitrageurs are expected to keep prices between the two tokens at parity.

Tokenomics

eXRD's supply is dynamic. It expands when XRD is deposited and wrapped, and contracts when eXRD is unwrapped and redeemed for XRD. This means the amount of eXRD in circulation at any given time reflects exactly how much XRD has been bridged to Ethereum.

Because eXRD is always backed 1:1, its economic value is tightly linked to XRD. There are no separate emissions or inflation mechanics for eXRD itself — its design is intentionally straightforward and transparent.

Ecosystem & Use Cases

The primary purpose of eXRD is to bring Radix's native value into Ethereum's DeFi ecosystem. This opens up liquidity pools, decentralized exchanges, yield protocols, and other DeFi applications to XRD holders.

The Radix network itself, which underpins XRD (and by extension eXRD), is built around Scrypto — an asset-oriented programming language — and the Radix Engine, a programmable DeFi execution environment. Together, these tools aim to make building secure DeFi applications much more accessible for developers.

Team, Governance & Community

Radix is built and maintained by Radix DLT, the team founded by Dan Hughes. The project is supported by the Radix Foundation, which manages token allocation and ecosystem development.

Governance on the Radix network uses a Delegated Proof of Stake system, where XRD holders stake tokens and participate in network security decisions. Community engagement happens across official Telegram channels, Twitter, and developer forums.

Advantages

• 1:1 backing ensures full transparency and redeemability at all times.
• No expiry on swaps means eXRD holders are never under pressure to bridge back.
• Access to Ethereum DeFi without sacrificing exposure to the Radix ecosystem.
• Audited smart contract by Quantstamp provides a baseline of security assurance.
• Arbitrage mechanism helps maintain price parity between eXRD and XRD naturally.

Risks & Challenges

• Custodian risk: XRD backing eXRD is held by a third-party custodian, introducing counterparty risk.
• Bridge risk: Swapping between eXRD and XRD relies on bridge infrastructure, which can be a security vulnerability.
• Liquidity dependence: eXRD's DeFi utility depends on sufficient liquidity being present on Ethereum platforms.
• Market adoption: As a bridged asset, demand for eXRD is tied to the broader adoption of Radix and its native ecosystem.

Long-Term Vision

The long-term role of eXRD is to serve as a permanent bridge between the Radix and Ethereum ecosystems. As the Radix network grows and its DeFi ecosystem matures, eXRD is designed to remain a stable gateway for Ethereum-native participants who want exposure to XRD.

The Radix team envisions their protocol eventually serving the needs of the entire global financial market, with eXRD acting as the conduit that connects Radix's scalable infrastructure with the liquidity and tooling already established on Ethereum.
