A paragraph about the problem is enough to start. We reply within two working days, usually with questions rather than a quote.
Solana programs in Rust with Anchor: account and PDA design, SPL tokens and Token-2022 extensions, tests against a local validator, and a security review.
Solana runs programs written in Rust under a different model from Ethereum: the code holds no state, and all data lives in accounts that each transaction must name in advance. We write Solana programs with the Anchor framework, design the account layout and its access checks, integrate SPL tokens, and test and review the result before it holds value.
Which accounts exist, who owns them, how program-derived addresses are seeded, and how the layout can change later.
Instruction handlers with explicit signer, owner and constraint checks — the checks whose absence is behind many Solana exploits.
SPL tokens and Token-2022 extensions such as transfer hooks and transfer fees, chosen for what the product needs.
Unit and integration tests against a local validator, including transactions built to pass the wrong accounts on purpose.
The upgrade key held in a multisig from the first deployment, releases scripted, and a decision on whether the program ever becomes immutable.
The account model and its invariants are written down before any instruction is coded.
Every instruction arrives with tests for the path that should work and the ones that should fail.
A second engineer who did not write the program tries to break it.
Devnet first, then mainnet, with the upgrade authority under shared control.

Engineers, designers and researchers who like systems that are hard to get right. Send something you built and what you would change about it now.
Based in India and working remotely, with overlap hours agreed up front so your team always has a time to reach us.
Guides on AI agents, RAG, MCP, tokenization and chain abstraction, written by the engineers who build them.
