What is Stader?
Stader is a multi-chain liquid staking protocol that offers ETHx, a liquid staking token for Ethereum. Originally launched on Terra in 2021, Stader has expanded across multiple blockchains including Ethereum, Polygon, BNB Chain, and others. On Ethereum, Stader distinguishes itself through a permissionless node operator model that enhances decentralization while maintaining competitive yields.
The protocol's Ethereum offering, ETHx, allows users to stake any amount of ETH while maintaining liquidity. Stader has implemented a permissionless system where anyone meeting the requirements can become a node operator, promoting network decentralization. The protocol emphasizes transparency, with on-chain verification of all staking operations and a strong governance framework through the SD token.
Stader's multi-chain experience gives it unique expertise in liquid staking mechanics across different consensus systems. This experience informs its Ethereum implementation, which balances accessibility, decentralization, and yield optimization.

How Stader Works
The Staking Process
Stader's Ethereum liquid staking follows a straightforward flow:
- User deposits ETH into Stader
- Receives ETHx at current exchange rate
- ETH distributed to permissionless node operators
- Operators stake on Ethereum's Beacon Chain
- Rewards accrue, increasing ETHx value
Understanding ETHx
ETHx is a value-accruing liquid staking token:
- Exchange rate vs ETH increases as rewards accumulate
- No rebasing complexity
- Fully liquid and composable
- Redeemable for ETH through withdrawal queue
- Usable across DeFi protocols
Permissionless Node Operators
Stader's decentralization approach:
- Anyone can become an operator (with requirements)
- Operators bond 4 ETH + SD tokens as collateral
- Collateral protects stakers from slashing
- Performance-based rewards
- Promotes geographic and client diversity

Risk Considerations
Smart Contract Risk
Stader contracts have been audited multiple times but smart contract vulnerabilities remain possible.
Slashing Risk
Node operator misbehavior could result in slashing. Operator collateral provides partial protection.
Depeg Risk
ETHx could trade below ETH in extreme market conditions, though arbitrage typically maintains the peg.
Operator Risk
Permissionless operators may have varying quality and reliability.
Multi-Chain Risk
Stader's multi-chain operations add complexity. Issues on other chains could impact reputation.
Liquidity Risk
ETHx has less liquidity than larger competitors like stETH.
Risk Disclaimer: DeFi protocols carry inherent risks including smart contract vulnerabilities and market volatility. Never invest more than you can afford to lose.Frequently Asked Questions
