Hire blockchain developers who treat an irreversible transaction like the constraint it actually is.
General-purpose blockchain and Web3 engineering, smart contracts, chain integrations, and wallet work, for teams that need broad on-chain capability rather than a single specialized build. If you already know you need a crypto exchange or an MLM compensation engine specifically, our dedicated builds for those are the more precise fit; this role is the generalist 'we need someone who knows blockchain' hire.
Solidity or Rust contracts written on the assumption an attacker will eventually test every edge case.
RPC nodes, indexers, and event listeners that keep an application in sync with on-chain state.
WalletConnect, multi-sig, and key-management patterns built for real funds, not a testnet demo.
Fuzzing and adversarial review before anything touches mainnet, not after an incident.
What strong Blockchain Developers know cold.

Answered before you ask.
Those are specialized builds we've done as dedicated engagements, see our crypto exchange and MLM software work elsewhere on the site. This page is for the broader hire: general smart contract, chain-integration, or wallet work that doesn't fit a single specialized category.
Depends entirely on the chain. EVM chains (Ethereum, Arbitrum, Base) run on Solidity; Solana runs on Rust via Anchor. We'll match the engineer to the chain your users are actually on, not push a default.
Automated fuzzing and static analysis first, then manual adversarial review, walking the contract's state machine looking for a sequence of calls that breaks an invariant. For anything holding meaningful value, we'll also scope a third-party audit rather than rely on internal review alone.
Yes. Most real engagements are mostly off-chain: the indexer, the API, the frontend wallet connection. The contract is often the smallest, most carefully built piece of a much larger system.
Every way out of this hire is already written down.
Not a fit? Replace anyone in the first two weeks. No questions asked, no replacement fee. We re-match from the same vetted pool.
You pay only for engineers who actually start. Seeing candidates costs nothing.
Dedicated and managed engagements run on a monthly rolling contract. Cancel with notice.
You see the number before you commit. Nothing is added on top of it later.
Bring us the on-chain problem. Three matched engineers in 48 hours.
Tell us what needs to live on-chain and what doesn't. We'll scope it honestly, including whether the honest answer is a simpler off-chain system.
We reply within an hour during our working day in India and the UAE.
