Nexus OrderBook DEX Apothem Testnet Launch

NEXUS — Mon, 30 Mar 2026 22:09:44 +0000

🚀 We're excited to launch the first fully on-chain orderbook DEX built on XDC Apothem Test Network — and we need your help to test it!

What makes Nexus Orderbook DEX different?
Most "DEXs" use AMM liquidity pools (like Uniswap). Nexus runs a real limit orderbook entirely on-chain — every order, match, and trade is executed by smart contracts, with no off-chain components other than a data indexer for chart/candlestick data. This is only possible on XDC thanks to its 500M gas block limit, speed, and efficiency — orders of magnitude beyond typical Ethereum limits — which makes complex on-chain matching economically viable.

What you can do:
-Place limit & market orders
-Create your own trading pairs
-Earn maker rebates & pay tight taker fees
-View real-time charts, depth, and trade history
-We need testers!
-We're currently live on XDC Apothem Testnet (free test tokens via the Faucet tab). Your feedback helps us find bugs and fine-tune the experience before we launch on XDC Mainnet at some point in the future.

👉 Try it now at this url: https://trade.thenexusportal.io/

Connect your wallet, grab some TXDC and test tokens from the faucet steps, and start trading. Drop any bugs or feedback, every test helps get us closer to a mainnet launch.

Key Features 🌟

🔄 Multi-Farm Rewards System

The Multi-farm/Super-farm rewards system sets NEXUS apart by allowing users to earn rewards in various tokens. This unique feature enables multiple different rewards simultaneously, mitigating some impermanent loss risks for liquidity providers.

🚀 Platform Utilization for Projects

NEXUS isn't just for individual users; it's a versatile tool for projects. Projects can reward their token holders with multiple rewards and yield farming opportunities, enhancing community engagement and adding value.

🏛️ Nexus Core Multi-staking

Stake NEXU and time-lock to earn LP tokens from trading fees, 10% NEXU inflation, XINU distributions, and more!

🎉 NEXUS Portal Opening Celebration and Invitation

We're making it easy to dive into the NEXUS platform! XINU or NEXU tokens are being dropped into thousands of wallets on the XDC network. If you received these tokens, you can start exploring the portal for free! Whether you're a DeFi newbie or a seasoned trader, it's your chance to experience all NEXUS DEX offers without using any XDC.

If you held 1000 XDC or more, you likely received a drop. Simply check the block explorer to see if you got any tokens! To add the tokens to MetaMask or another wallet, use the official contract addresses:

NEXU: 0x6daf228391e388b05bbc682fea3cb1cc3e38c44e
XINU: 0x834a6cd4cc361e4b9b1694d2e9df3eeb0cb45c5a

Missed the Drop? No worries! New users who missed out can still get a small amount of XINU and NEXU to explore the platform. Just follow our socials and complete a request in the NEXUS Discord to claim your tokens. (Limited time and supply!)

Also you can single side-stake WXDC or FXD in the Multi-farm to earn XINU for free, with no risk!

💡 Token Information

🌌NEXU: The core platform token of NEXUS, NEXU powers the exchange and yield farming rewards. It can be staked in various places in the Multi-farm or Multi-staking. NEXU will also play a key role in future governance and has additional uses yet to be revealed.

👽XINU: A fun ecosystem token to incentivize and support the XDC Network. XINU is used to test and interact with various features within and beyond the NEXUS ecosystem, complementing NEXU and supporting multi-earning pairs.

[Informative] ✨Introducing The Nexus Portal

NEXUS — Wed, 03 Jan 2024 01:13:21 +0000

Greetings,

We are excited to announce that The Nexus Portal is now live on the XDC Apothem testnet! We have been developing The Nexus Portal for XDC and other EVM chains since early last year, and we've reached our first significant milestone – deploying on XDC Apothem.

The Nexus Portal is a unique multi-dimensional DeFi/NFT ecosystem. What sets Nexus apart?

Holographic UI: A special user experience, that feels like logging into a SciFi/futuristic interface.
Superfarm Multi-Reward System: A novel incentive system for liquidity providers to earn rewards that can help mitigate impermanent loss. XDC community projects can gain whitelisting to create their own single or multi-earning pools, enhancing liquidity provider incentives for the community.
Multi-Staking System: Allows staking of NEXU and/or NFTs to earn diverse rewards.

NexusMultiStaking

This novel feature enables users to stake and time-lock NEXU and/or NFTs, earning 10% of the daily NEXU rewards and a variety of other tokens including LPs from different contracts.

NexusGenerator

Mints NEXU: Distributes NEXU to applicable LPs. -Superfarm: Can distribute a plethora of XRC-20 Superfarm rewards to different LPs.
Minting Rate: Begins at 5 NEXU per block, decreasing approximately every 25K blocks (half a day at XDC's 2-second block time). This is the current setting on apothem and is subject to change for main net.
Max Supply Timeline: At the current rate, projected to reach max supply of 1.1 Billion in about 42 years.
