Contract creation with BlockCypher
View bc-contract-doc
# The contract API includes the following endpoints (API token always required):
#
# POST /v1/eth/main/contracts
# Creates a new contract. Expects the solidity definition, the private key paying for the publication, the name of the
# contract to be published, the gas amount to use and eventual constructor parameters. The solidity code is compiled
# and the contract creation transaction built and broadcasted. Both the code and the ABI are saved for further
# retrieval. If invoked without contracts to publish, simply compiles and returns the result of compilation.
# Otherwise, along with the compilation results, will return the contract address and creation transaction hash and the
# contract methods will be exposed as endpoints (see below).
