Writing ABI Compliant Smart Contracts PyTEAL
summary
Explains Algorand ABI support in PyTeal and shows a working algobank demo with three methods (deposit, get_balance, withdraw) that compiles to TEAL, emits an ABI JSON and executes CLI calls successfully in a local sandbox. Demonstrates atomic groups, inner transactions for withdrawals, decoded return values from logs, and the router that maps method selectors; shows reference types (account/asset/app), transaction types, tuples (limit 5) and dynamic arrays, and that the router can produce ABI JSON used by SDK/goal to call methods.
