Import MRC20 token from Amoy

Tamas_Toth · February 19, 2025, 11:41am

Hello! I created a simple MRC20 token on Bitbond Token Tool. On that platform was no such function that allow me to wrap my token. For testing purposes yet! Only want to implement and importation of my existing token.

I read an article about the wrapper process, but I think it is outdated. Can you help, which articles can be relevant in my case?

Thank you for your help!

Hi, welcome to the community!

Wrap token? Like wrapping ETH to WETH? Or something else?

Hi Skyge!

I have a separate testnet token... Its first version was deployed on Amoy Polygon network. Yet, slowly discovered that my idea is possible yet to implement on a different chain.

Its not the core test token, like POL on Polygon network. My token its not core ETH... Its called SRC. On Ethereum Sepolia are deployed now by Bitbond Token Tool. Now it turned into an ERC 20 token. I want the existing token allowing become wrapped like wSRC of SRC.

I started to study the OZ documentation, but I have little knowledge about web 3. Still its a big tall for me, can you help in this process? Which article can be relevant for my case?

Thank you for your help!

I already have an ERC20 Ethereum Sepolia token. I don’t want to recreate this token on the OpenZeppelin Defender interface to simply duplicate it under a different address. Instead, I’d like to import the token that already exists on the Bitbond platform using its current token address, and from that, create a wrapped token. Which documentation would be relevant in this case?

How about this wrapper contract?
