Cross-chain staking allows you to stake tokens on one blockchain while using assets from another. This process typically involves bridging assets, locking them in smart contracts, and earning rewards. Here's a step-by-step guide:
1. Choose a Cross-Chain Staking Platform

Popular platforms that support cross-chain staking include:
-
Polkadot/Kusama (via parachains)
-
Cosmos (ATOM) (via IBC)
-
Thorchain (RUNE) (for native cross-chain swaps & staking)
-
Ankr (ANKR) (multi-chain liquid staking)
-
Stargate Finance (STG) (cross-chain DeFi)
-
Synapse Protocol (cross-chain liquidity & staking)
-
LayerZero-based protocols
2. Bridge Your Tokens to the Target Chain
Since you can't stake tokens directly across chains, you need to bridge them first:
-
Use a cross-chain bridge like:
-
Multichain (formerly Anyswap)
-
Synapse Protocol
-
cBridge (by Celer Network)
-
Wormhole
-
Swap to a wrapped version (e.g., WBTC for Bitcoin on Ethereum).
3. Stake via a Cross-Chain Protocol
After bridging, stake using:
-
Liquid Staking Derivatives (LSDs): Stake via platforms like Lido, Rocket Pool, or Ankr to get staked tokens (e.g., stETH, rETH) that can be used across chains.
-
Yield Aggregators: Use Stargate, Beefy Finance, or Yearn Finance to auto-stake across chains.
-
Thorchain: Stake native assets (BTC, ETH, etc.) without wrapping.
4. Monitor & Claim Rewards
-
Track rewards via the staking platform’s dashboard.
-
Some chains allow auto-compounding (e.g., Cosmos via Keplr Wallet).
-
Withdraw via the reverse bridge if needed.
Example: Cross-Chain Staking ETH → Polygon
-
Bridge ETH to Polygon using Synapse or cBridge.
-
Stake MATIC or wrapped ETH via Ankr or Lido on Polygon.
-
Receive aStMATIC or stETH (usable in DeFi across chains).
Risks of Cross-Chain Staking
-
Bridge hacks (e.g., Wormhole, Ronin exploits)
-
Smart contract risks
-
Impermanent loss (if staking in LP pools)
-
Slippage & high gas fees
Best Practices
✔ Use audited bridges (e.g., LayerZero, Stargate)
✔ Prefer native cross-chain staking (e.g., Thorchain) over wrapped assets
✔ Check APY vs. gas costs (high fees may negate rewards)
