A Developer's Guide to Stader ETHx: A Dual-Reward Liquid Staking Token

Stader Labs Official offers a unique liquid staking solution on Ethereum with its ETHx token. Unlike traditional LSTs, ETHx is designed with a dual-reward mechanism that benefits stakers and supports a decentralized network of node operators. This guide explains the technicals.

Core Concept: ETHx Explained
When you stake ETH with Stader, you mint ETHx. Here’s the key difference: Stader ETHx Staking splits rewards.

Staker Rewards: 90% of the staking rewards are passed directly to the ETHx holder, causing the token's value to appreciate against ETH.

Node Operator Rewards: 10% of the rewards go to the Stader Labs Node Operator, creating a powerful incentive for a permissionless set of operators to join the network.

This model is a core part of How to stake with Stader Labs.

Step 1: Staking ETH for ETHx
The process is streamlined for simplicity.

Navigate to the Stader Labs Ethereum staking page.

Connect your Web3 wallet.

Enter the amount of ETH to stake.

Confirm the transaction. You will receive ETHx in your wallet and begin accruing rewards.

Step 2: Understanding the Reward Mechanism
In addition to the 90% of ETH staking rewards, ETHx holders are also eligible for SD Token Rewards. The SD token is Stader's governance token, and distributing it to stakers aligns long-term incentives.

The modular architecture also extends beyond Ethereum. The Stader Labs Multi-chain Guide shows similar LSTs on networks like Stader Labs Polygon and Stader Labs BNB.
