I am an blockchain+crypto+ethereum developer and I can develop your project. I have worked with ERC20 tokens, wallets, Raiden, etc and can handle your project with ease.
Worked with ERC20 tokens, wallets, Raiden, MetaMask. I have developed Dapps (Decentralised applications) on ethereum and helped companies launch their ICOs also.
