5 min readApr 10, 2024


XLM users can now send their tokens to Zenlink DEX on Polkadot through the Spacewalk Bridge, opening up access to several XLM pools, including the new XLM.s/PEN pool. This marks the first occasion for Stellar Lumen holders to directly contribute liquidity on Polkadot and reap rewards.

To participate in the PEN/XLM liquidity pool and earn rewards on Zenlink, you’ll first need to acquire PEN and XLM tokens. Here’s a comprehensive guide to get you started, including how to use Spacewalk to acquire XLM:

1. Get PEN
2. Bridge XLM with Spacewalk
3. Get a Polkadot Wallet & Connect on Zenlink
4. Choose the Pool
5. Add Liquidity

Step 1. Get PEN

If you already have PEN >> skip to step 2.

From Centralized Exchange

  • Sign up with MEXC and purchase Pendulum (step-by-step guide) Withdraw your PEN tokens to your Pendulum address. If you need help setting up your Polkadot/Pendulum wallet, check out our docs.

From Decentralized Exchange (DEX)

  • PEN is listed on Zenlink DEX and StellaSwap.
  • On Zenlink DEX, connect your wallet to Zenlink, and ensure your wallet is on the Pendulum network. Go to the “Swap” section of Zenlink. Select the asset you want to swap for PEN such as DOT or GLMR.
  • You can also swap a variety of Polkadot native assets (e.g. DOT, USDT, USDC) for PEN tokens using the Stellaswap trading UI on Moonbeam.
