For example, if a smart contract were set up to transfer USDC worth one BTC from Jane’s wallet to Jill’s wallet at a certain date, the smart contract would need to reference an oracle to determine the exact value of BTC in USDC to transfer to Jill’s wallet – and have awareness of the date and time.
