XLM holders can now transfer tokens to Polkadot’s Zenlink DEX via the Spacewalk Bridge, and access various XLM pools. For the first time, XLM holders have the chance to add liquidity and earn rewards natively on Polkadot.

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

1. Get PEN (for gas fees)
2. Bridge XLM with Spacewalk
3. Get DOT
4. Transfer DOT to Pendulum network
5. Get a Polkadot Wallet & Connect on Zenlink
6. Choose the Pool
7. Add Liquidity

Step 1. Get PEN (for gas fees)

First, you will need a small amount of PEN (less than 10 PEN) to fund the gas fees for Spacewalk and Zenlink transactions. 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.

Step 2. Bridge XLM with Spacewalk

I. Stellar Wallet Setup

  • Visit the Lobstr wallet website to create a Stellar wallet.
  • If you already have a Lobstr wallet with Stellar assets, proceed to the next step.

II. Acquire Assets on Lobstr

  • Utilize MoonPay or Stripe within Lobstr to purchase XLM or USDC with fiat (e.g., USD, EUR).

III. Bridge Assets with Spacewalk

  • Navigate to the Spacewalk on the Pendulum Portal.
  • Select ‘To Pendulum’ and choose the asset (XLM) you wish to bridge.
  • Enter the XLM amount and initiate the bridge process. Connect your Polkadot wallet if prompted, then click ‘Approve’.

IV. Deposit via Lobstr

  • Return to Lobstr, select ‘Send’, and enter the deposit details as specified by Spacewalk.
  • Ensure to paste the recipient’s address from the ‘In a single transaction to’ section on Spacewalk.
  • Then, tick the ‘Add Memo’ box to input the required text memo.
    Note: Stellar transactions require memos for processing.
  • Review your payment details before clicking ‘Send.’

V. Success

  • The bridging transaction usually completes within a minute. Check the status via the ‘Transfers’ tab on Spacewalk.
  • If the transaction hasn’t been processed after 10 minutes, reach out to support through Telegram or Discord.

Step 3. Get DOT

From Centralized Exchange

From Decentralized exchange (DEX)

  • DOT can be purchased on several DEXs, including Stellaswap, Zenlink, and HydraDX. Then, send the DOT to the Pendulum address.

Step 4. Transfer DOT to Pendulum network

If you already have DOT on the Pendulum network >> skip to step 5.

To send DOT to the Pendulum network, please use NovaWallet on your mobile for the transfer.

  • Within NovaWallet, locate ‘Polkadot’, then click DOT.
  • Choose ‘Send’. Then, switch the recipient network to Pendulum.
  • If you are using the same wallet for Zenlink, select ‘Myself’. If using another wallet later for Zenlink, carefully copy the correct Pendulum address.
  • Enter the DOT amount and continue to execute the transfer.

Step 5. Get a Polkadot Wallet & Connect on Zenlink

  • For newcomers, a user-friendly wallet experience is crucial. We suggest Talisman or Subwallet for desktop users, and Nova Wallet for those on mobile.
    (Note: After transferring DOT to the Pendulum network with NovaWallet, it’s advantageous to continue using NovaWallet for a more seamless experience.)
  • Once your wallet choice is made, navigate to Zenlink’s Pool UI.
  • Click “Connect Wallet” and select your wallet type. For NovaWallet users, choose ‘Wallet Connect’, scan the QR code with NovaWallet, and complete the connection steps.
  • Once connected, ensure your wallet is switched to the Pendulum network.

Step 6: Choose the Pool

  • At ‘All Pools’, it displays all the available liquidity pools of the networks. Switch the ‘All Networks’ to ‘Pendulum’ to see the available pool on Pendulum.
  • Select the DOT/XLM pool to provide liquidity.
  • Once you have selected the pool, click ‘Deposit’ which will bring you to the page for adding liquidity.

Step 7: Add Liquidity

  • Enter your desired amount of DOT or XLM.s. The corresponding amount needed for the other token in the pair will be automatically calculated based on the current pool ratio.
  • Review the pool details. After approval, click on “Add Liquidity” to add your tokens to the pool. Then, confirm the transaction in your wallet.
  • Navigate to the ‘My Position’ section to view your contributed liquidity.
