EasyBitcoin is a simple haskell library providing types and class-instances for bitcoin related code; it also include an small set of functions to handle addresses, transactions and escrows.
I tried to keep it as simple as possible while yet, being usefull to code applications that need to read/create
bitcoin transactions and multisignature escrows. It started as a forked from the Haskoin haskell bitcoin library.
Documentation about its usage and some examples can be found on it Hackage page.
