Metamask compatible json-rpc server

This project is a proof of concept - It implements the minimum required ethereum rpc apis to be able to accept simple metamask transactions (transfert only).

This will be included in sub.net library.

Prerequisites :

• dotnet 7 sdk to build the project

• Metamask extension depending on your browser :

  • chrome web store
  • firefox addons

Clone the subdotnet/metamask-mini-api repository

git clone https://github.com/subdotnet/metamask-mini-api.git

Run the demo :

1) The simple blockchain has 2 prefunded wallets. You can import these private keys in metamask :

• 616b28bfaa49973faf243ec3296a01675c742533f06c325c78f3d63ceef67963
  • public key : 0x145272D2e9828aE2A25913c0643ff0cb486bBAD1
• ff067934635e368095f47bfc72942087e07b097d0c541b8f4602dcd255de50fd
  • public key : 0x169E72fa2CC6Ec61402dc3C5D3c16ACc4d83BAD2

The public keys end with "BADx".

Install metamask and import prefunded dev addresses :

2) Run the project
Inside the cloned repository, simply execute dotnet run and you should have this output in the console : json-rpc api listening on http://localhost:5035

3) Configure localPLOP network in metamask
Open metamasks settings and go to the network tab.
Add new network with the folowing values :

• name : localPLOP
• RPC Url : http://localhost:5035/
• Chain id : 12345
• Currency symbol : PLOP

You should have 42 PLOP in your BAD1 wallet and 1337 PLOP in your BAD2.

Configure custom network in metamask and transfer funds :
