This app is a digital pen for signing any Factchain-enabled application.
Factchain enables digital signatures to provide proof that a user signed or otherwise agreed to the contents of a file, adding true "trust" to transactions.
Factchain provides proof that files are not fraudulent and have not been altered in any way as well as proving that a user "signed" the file.
Factchain can use the Ethereum blockchain to provide public tamper proof evidence. This allows 3rd parties to independently validate the authenticity of a file and its associated signatures.
