A Solana program is only half a product. Your frontend, backend, bots and partners all need to talk to it: build the right instructions, pass the right accounts, sign, send and confirm. That is the job of a program client. A good client makes your program easy and safe to use; a weak one causes failed transactions, confused users and support tickets.
What We Build
- TypeScript clients for web apps and Node.js backends, built on the current Solana JavaScript libraries.
- Rust clients for bots, high-throughput services and other programs.
- Generated code from your IDL: with Anchor or code generators, instructions and account types are generated from the program's interface definition, so client and program never drift apart.
- Account parsing: deserialising program accounts into typed objects, including PDA derivation helpers.
- SDKs for partners: a documented package that other teams can integrate without reading your program code.
Transactions That Land
Most frustration with Solana apps comes from transactions that expire or fail. We build clients that handle this properly:
- Priority fees: setting a compute unit price based on recent network conditions, so transactions get included during busy periods.
- Compute budget: requesting the compute units a transaction actually needs, based on simulation, instead of the default.
- Simulation first: simulating before sending, so errors are shown to the user before they sign.
- Blockhash expiry and retries: tracking when a transaction's blockhash expires and resending safely, without double execution.
- Confirmation levels: choosing between processed, confirmed and finalized depending on what is at stake.
- Versioned transactions and lookup tables: for transactions that touch many accounts and would otherwise exceed the size limit.
Frequently Asked Questions about Solana Program Clients
Can you build a client for a program we did not write?
Yes. With a published IDL it is straightforward; without one, we work from the program's source or reconstruct the instruction layout, and test carefully against the deployed program.
TypeScript or Rust?
TypeScript for web frontends and most backends. Rust for latency-sensitive bots, high-volume services, or when the client shares code with the program itself. Many projects have both.
Why do Solana transactions fail during busy periods?
Usually because the priority fee is too low, the compute budget is wrong or the blockhash expires before inclusion. A well-built client handles all three.
Who owns the code?
Ownership of the source code is set out in the contract, and the code can be fully yours, including documentation and tests.
