Solana Program Entry Point — Deploy & Verify — Forge College

Need a deployable Solana program entry point that correctly handles borsh-serialized client requests and survives real-world input? This lesson walks you through assembling, testing, and deploying a functional entry-point implementation that is ready for client interaction and verification. What you'll learn In this lesson you will integrate validated borsh schemas, hardened entry-point parsing, and a client-side test harness into a single deployable artifact. You will compile a Solana program binary with deterministic borsh deserialization, add runtime checks that detect malformed payloads (buffer-length mismatches, enum discriminant errors), and instrument logging to surface structured fields at the entry boundary. The lesson shows concrete build steps and code snippets for both the on-chain program and the client harness, how to run the harness against a local validator or devnet, and how to produce a concise end-to-end verification report that includes serialized payload bytes, program logs, and test assertions. Who this is for Intermediate Solana developers who already know basic Rust and Solana program concepts and want to produce a deployable, testable entry-point implementation and verification artifacts. Key topics covered - Deterministic borsh schema integration and versioning hooks - Entry-point instruction parsing, dispatch, and robust input validation - Runtime checks for malformed borsh payloads and edge-case fixes - Client-side test harness: serializing instructions and submitting transactions - Deploying to a local validator or devnet and inspecting program logs - Producing a verification report and runnable deployment artifacts Ready to assemble, deploy, and verify your program-entry-point deliverable?
