PulseChain Native PLS bridge for direct transactions

Latest News

On June 2, the PulseChain community celebrated the arrival of the long-awaited Native PLS Bridge to Ethereum and vice versa. The news was announced by Richard Heart on Twitter and was met with great enthusiasm. PulseChain was almost inaccessible for new users despite another bridge being in operation soon after launch. With the arrival of Native Bridge, two-way communication and direct unwrapping of WPLS are now available for everyone.

PulseChain Native Bridge

PulseChain has been a mostly isolated network since its launch on May 13. For the first few days, the chain was operational only for those who participated in the sacrifice phase that ended almost two years ago. Native Bridge is a communication channel between Ethereum and PulseChain. It works both ways, and it transfers assets like WPLS from Ethereum to PLS on PulseChain. 

Richard Heart announced it on Twitter:

Despite the Pulse Ramp bridge opening soon after launch, it didn’t unwrap ETH on Pulsechain, and people who were new to the network couldn’t make their first transaction without having gas.

This was a major issue that people were trying to solve with different faucets, donations, and p2p trading until CEXes like OKX or Kanga provided direct access to PLS. Now, with the advent of Native Bridge, the issue of unwrapping is solved, and sending WPLS from Ethereum warrants that you will get PLS and be ready to make transactions straight away. For this, you need to make sure to use a new WPLS contract on Ethereum:

There’s a daily limit on the quantity of PLS that can be bridged. The minimum WPLS per transaction is 50k, and the maximum is set at 500B WPLS. The bridge fee is 0.3%. You can bridge also other tokens making sure first there’s a pool on the other side. If no pool exists, you won’t be able to swap this token for any other. The UI of the bridge doesn’t show if there’s a pool or not. Until it’s not shown somehow, it’s probably better to not bridge other tokens than PLS however you could  check on if pool exists and then move your tokens.

How to use the Native Bridge

  1. Connect your wallet
  2. Choose WPLS from the drop-down menu
  3. Insert the amount of WPLS to transfer from Ethereum to PulseChain
  4.  Approve allowance in your MetaMask
  5. Send tokens

If you want to send funds from PulseChain to Ethereum then you need to switch the network in your MetaMask first and then send PLS to receive WPLS on Ethereum. You’ll need ETH on Ethereum to unwrap the token though. 

When you send funds from PulseChain to Ethereum you need to switch to the destination chain and go to “Transactions” to claim your tokens.

On the image below, you can see which token on PulseChain corresponds to a token on Ethereum. You can use PulseCheck to verify contract addresses on both chains.

In the next example, we use WETH from Ethereum token on PulseChain to move it across the bridge, where we’ll get ETH on the Ethereum network. The advantage of moving WETH from Ethereum is that you do the wrapping on PulseChain, where gas costs are low, and you get an unwrapped ETH on the other side. You don’t need to do the unwrapping there anymore and suffer high gas fees. Remember to switch the network to Ethereum and claim your ETH on the other side of the bridge. Claiming ETH incurs a fee so make sure to have some ETH on your account.
