PoC built with Cairo-0.4.1 compiler

• Update L1 to Goerli testnet
• Add L2 contract interactions: Proxy contract can read from/write to RFQ contract
  • use get_caller_address for permission check
• Add unit tests

PoC built with Cairo-0.3.0 compiler

• Add deposit/withdraw to RFQ program
• Add L1 <-> L2 contract interaction, i.e., interaction between Ethereum L1 contract and StarkNet contract
  • using token deposit/withdraw as an example
• Note: StarkNet periodically cleans up contract state so don't expect contract state to remain

PoC built with Cairo-0.1.0 compiler

• Simple RFQ order settlement Cairo program
• State comprise two layer dicts: State -> Accounts -> Token balances in an Account
• Cairo program is compiled with Cairo-0.1.0 compiler and it is a stateless program, i.e., you have to provide the state and verify the state in the Cairo program

PoC built with Cairo-0.2.0 compiler

• Update RFQ program rfq.cairo into a StarkNet contract
• The balances are now kept in the contract, i.e., you don't have to provide state to the Cairo program anymore
