- The example traces a TypeScript instruction through six checks, including account ownership, instruction-data length, and checked u64 arithmetic.
Field notes
The counter walkthrough maps a TypeScript function to generated C and labels the generated checks in sequence, including account count, signer status, writability, ownership, discriminator, and data length. It also shows little-endian decoding of an eight-byte `u64` argument and a checked addition that returns an overflow error instead of wrapping. The page links to examples covering account data, program-derived addresses, token operations, and cross-program invocation.
