What is Stader Labs (SD)?

🟢 The simple version
Plain English — no jargon. Start here.
Stader Labs is a multi-chain liquid staking platform — one protocol, multiple blockchains — where you can stake ETH, MATIC, BNB, NEAR, Hedera, and other assets and receive liquid staking tokens (MaticX, BNBx, ETHx, etc.) that let you earn staking rewards while keeping your assets deployable in DeFi.
Why multi-chain liquid staking?
Most liquid staking protocols specialise in one chain: Lido dominates Ethereum, Marinade dominates Solana, and so on. Stader's approach is to build the same liquid staking infrastructure across many chains simultaneously, using a common codebase and the SD governance token to tie them together. For users on chains like Polygon, Hedera, or BNB where dedicated LST options are fewer, Stader often provides the most liquid and battle-tested option available.
Stader's flagship Ethereum product is ETHx — a decentralised liquid staking token with a focus on permissionless node operators and a lower collateral requirement for operators (4 ETH instead of the 32 ETH full requirement, with the rest provided by Stader's pool). This design targets solo stakers and smaller operators who want to run validators without the full 32 ETH.
SD token — utility, not just governance
SD is notable because it has actual utility beyond voting. Node operators on Stader are required to hold SD tokens as collateral — a minimum SD stake is required to run a validator on the Stader protocol. This creates ongoing buy pressure for SD from operators entering the network. SD is also used for governance and as a fee-sharing mechanism. This utility-driven demand model differentiates SD from purely governance-only LST tokens.
Is SD legal in India?
Yes. SD qualifies as a Virtual Digital Asset (VDA) under Indian law. 30% tax on gains and 1% TDS applies. Always consult a tax professional. Note: Stader Labs was founded in India (Bangalore) and has significant Indian team presence.
🟡 A bit more detail
For when you want to go a little deeper.
ETHx — Stader's Ethereum LST
ETHx uses a "permissioned + permissionless" node operator model. Permissioned operators (curated by Stader) run validators with standard capital. Permissionless operators can enter by bonding 4 ETH (plus SD tokens) — Stader's pool provides the remaining 28 ETH. This creates a lower entry barrier for solo validators, potentially improving Ethereum's decentralisation compared to Lido's more centralised operator set. ETHx is integrated as collateral in Aave and other Ethereum DeFi protocols.
Multi-chain LST portfolio
Stader operates: ETHx (Ethereum), MaticX (Polygon — now POL), BNBx (BNB Chain), NearX (NEAR Protocol), HBARX (Hedera), and previously others. Each has separate smart contracts and node operator sets on that chain. The SD token provides a common governance and economic layer across all deployments. MaticX has been particularly successful, becoming one of the largest LSTs on Polygon by TVL.
Stader's multi-chain strategy means it has thinner market share on each individual chain compared to specialists. ETHx is much smaller than stETH (Lido). MaticX competes with Lido's stMATIC. Being number two or three on multiple chains is a defensible but not dominant position. SD's operator collateral requirement creates genuine token demand — worth tracking staking/operator growth as a health metric. Live data: CoinGecko

SD collateral mechanism — technical
When a permissionless node operator registers on Stader ETHx, they must bond 4 ETH plus a minimum amount of SD tokens (the SD amount scales with the number of validators they want to run). The SD acts as slashing insurance — if the operator is slashed on Ethereum, their SD bond is used to compensate the pool depositors first, before touching the pooled ETH. This SD collateral is locked for the duration of their operation. When they exit, SD is returned. The collateral requirement creates a structural floor for SD demand tied directly to Stader's TVL and validator count growth.
