"Researching" a smart contract just means broadcasting a transaction to a node in the network. There are over 15,000 Ethereum full nodes, you can hit one not in the US from your own reported location not being in the US. The gas you use in your address also needs to be unlinked from your identity too. So basically over tor just shapeshift like $5 worth of Monero to an ethereum address you just created. A transaction with a specific set of instructions will execute the smart contract program on any of the 15,000 nodes in the network.
