Software for Solana

Hello, I have experience in development on Solana, but I will say right away that the speed depends not only on how the program is written (this is generally secondary), but rather on RPC, Jito, and other factors that need to be set up and obtained. Therefore, I can write the code in Rust without any problems, but I will explain where to get the RPC and other things for the necessary speed.

Hello.
I am ready to implement simple and fast software for Solana in Rust or JS.

The task is clear:
transactions are executed strictly in the specified order and time window, or not executed at all.

I have experience working with Solana, particularly with performance optimization and transaction execution control.
I can offer a neat and reliable implementation without unnecessary logic.

… Deadlines and cost are discussed after clarifying the details.

Hello, Ilya

Write the word "arbitration" in a private message and I will write my proposal.

Already had experience

Ready to do it, but would like to see a clear specification

If there is such an opportunity

And what is the deadline

Hello.
I can implement simple and reliable software in Rust (Solana SDK) or JS/TypeScript for fast transaction execution on the Solana network.

The solution will:
- execute a set of transactions strictly in the specified order
- operate within a clear time window (time slot / timestamp / block height)
- use the all-or-nothing principle — if conditions are not met, transactions are not sent at all, focusing on minimal delay and predictability of execution
Technically possible:
- pre-preparation and signing of transactions
… - control of recent blockhash / slot
- parallel sending or atomic logic (through bundling / simulation check)
- protection against partial execution

I am ready to discuss:
- Rust vs JS (depending on latency requirements)
- conditions of the time window
- number and type of transactions
- RPC / priority fees

I can quickly assemble an MVP and then refine it for a specific use case.

Good day. I have reviewed the task, and it is clear that a simple yet reliable software for Solana is needed, which executes transactions strictly in the specified order and time window, or does not execute them at all.

I can implement the logic with an emphasis on speed, sequence control, and correct handling of the "all-or-nothing" scenario, without unnecessary complications.

Please write to me in private messages with more details:
what specific transaction scenario,
how the time window is set,
whether interaction with specific programs/contracts is required,
the format of the result (CLI, script, service).
…
After this, I will be able to propose the optimal implementation option, timelines, and budget.

Hello. I will create a small software for Solana that sends transactions strictly in the specified order and "window," otherwise it does not send at all. I see the scenario like this: I will prepare and sign the transactions in advance, at the moment of the window the software only checks the slot/time, updates the blockhash, and sends. If "all or nothing" is needed for several transactions, I will create an atomic bundle (sequentially in one slot). If only one transaction with multiple instructions is sufficient, I will pack everything into one tx, then atomicity is guaranteed by the protocol. For strict "only within the window," I will add an on-chain guard (time/slot check) so that the network physically cannot execute outside the window.

I need to clarify: how many transactions in the chain (1 or 2–5), the window by time or by slots, and through which RPC/Jito you will be sending.

Good evening. I have extensive experience working with Solana, both with JS and Rust. Please clarify in private messages which specific transactions need to be executed and in what order.
