Deploying dollars on the blockchain
summary
Builds an ERC20 USDK 1:1 backed token on a local Ganache chain, deploys the contract, and mints tokens via Go code using the go-ethereum bind package. The mint flow is split into mint with explicit signing: create an unsigned transaction, sign it separately, then broadcast it. Tests run with go test (one failing case shows 0 minted instead of expected 1.5), the demo mints 100 USDK to a MetaMask address, and the full pipeline works locally.
