v0.21.0

Introduces new RemoteError and ParserError constructors into Web3Error, to allow more graceful handling of failure modes when making requests to Web3 providers.

v0.20.0

• rework type-level numbers in base 10 with Increment class #88 @safareli

Using purescript-eth-core

In an effort to move all js dependencies to the corner, we factored out the core modules to purescript-eth-core. This means that all the HexString and BigNumber utils got pushed there, but also that library exports additional functionality like RLP encoding and ECDSA support

MonadPar Instances

We introduce an opaque Web3Par type with

instance monadParWeb3 (Web3Par e) (Web3 e)

deploying helper functions

Deploying (#73)

* deployContract

* untag args

* eq error instances

* eq error instances

* add status

* fix status

Using ReaderT for providers

We use a ReaderT in the Web3 monad stack rather than a phantom type and proxy approach.

upgrade purescript-tagged

Release (#64)

* use published version of purescript-tagged

* auto publish tagged versions on travis

Better Transaction Options

TransactionOptions now takes a phantom type indicating the currency contained in it. eth_sendTransaction converts this to Wei on the way out the door. Then _value lens got smarter.

Also started using the modules package for better interplay between Int and BigNumber and Value.
