Description

Issue by kennyrowe Thursday Nov 16, 2017 at 20:52 GMT Originally opened as https://github.com/dapphub/seth/issues/20

Description:

Add a flag to seth to check the calldata of an onchain transaction.

Specification:

$ seth -verify <txHash> <bytes>

Example:

$ seth -verify 0x036ae8fa1a31e36787f524e3ac21ec2fa44d3b0ff9bcf3fdd3a7933498a18095 $(seth calldata 'transfer(address, uint256)' 1dacd2508778b5caebe71f86f646793acfe22b89 $(seth --to-uint256 1501933000000))

Contributor guide

Research direction
Add a ` verify` flag to seth that takes a transaction hash and bytes, then fetches the transaction and compares the calldata. Implement in Haskell, likely modifying the CLI parser and adding a new function to interact with an Ethereum node.
