A practical orientation for Solana developers
Developer work begins with a clear understanding of the boundary between an application, a program, an endpoint, and the network. Gajema explains those boundaries so readers can approach documentation with useful questions rather than assumptions. This page is educational and is not a substitute for current technical documentation, testing, code review, or security assessment.
A reliable workflow is less about memorizing every term and more about making dependencies visible. Identify the accounts involved, understand instruction permissions, record the software versions used, and test behavior in an environment that does not expose sensitive data.
Before writing code
- Define the user action and the network state it needs to read or change.
- Identify authorities, signers, accounts, programs, and external endpoints.
- Read current documentation and note version-specific behavior.
- Decide how errors, retries, timeouts, and partial progress will be observed.
Development sequence
- Write a small requirement and a diagram of the data flow.
- Build a minimal test case with explicit inputs and expected outputs.
- Inspect logs, account state, and returned errors rather than relying on interface appearance.
- Review authority boundaries and failure paths with another developer.
- Document the tested version, known limitations, and rollback approach.
The sequence is deliberately conservative. A feature that works in one local example may behave differently when accounts are missing, permissions differ, a provider is unavailable, or a transaction is retried. Documentation should preserve those conditions for the next person who maintains the code.
“Good developer documentation makes assumptions visible before they become production surprises.”
Questions by component
| Component | Review question | Evidence to keep |
|---|---|---|
| Program | Which instructions and authorities are accepted? | Tests, interface definition, source reference |
| Account | What data is stored and who may change it? | Schema, owner, permission notes |
| Endpoint | What limits, errors, and availability conditions apply? | Provider documentation and observed logs |
| Client | Which software version and configuration are used? | Lockfile, release note, environment record |
Useful review checklist
- Inputs are validated before instructions are assembled.
- Unexpected account state produces a readable error.
- Secrets are kept out of source control, logs, and screenshots.
- Retries cannot create unintended repeated actions.
- Dependencies and release versions are recorded.
Developer questions
Is an endpoint the network?
No. An endpoint is an interface operated by a provider or organization. Its availability, limits, and data presentation should be evaluated separately from the underlying protocol.
Why document account permissions?
Because an application may appear simple while relying on several authorities and data containers. Permission notes help reviewers understand what a request can change.
Where can I learn the vocabulary?
Use the glossary alongside the architecture and infrastructure guides, then confirm exact behavior in current source documentation.
