Writing Smart contracts in pyTEAL
summary
Shows how PyTeal generates TEAL from Python ASTs, compiles to bytecode and deploys via the SDK, and demonstrates concrete primitives: 64 global keys and per-app local state, 256 scratch slots for temporaries, 64-bit unsigned integers, logging as the only direct return channel, and no reentrancy across contract calls. Covers inner transactions (up to 256 in a group), the need to predeclare resources and accounts, the subroutine decorator to avoid code bloat, and cautions about weak timestamp guarantees and atomic group ordering.
