Most places you can hire blockchain developers sell you a résumé and a rate. You interview, you onboard, you read the pull requests, and when a contract does something it should not, you find out on a public chain.
We attach the review to the capacity. Smart contract, protocol and indexing work lands checked before it reaches your branch, and one named person is accountable for it.
That matters more on a chain than anywhere else. Off-chain, a bad write is reversed quietly. On-chain, it is public, permanent, and somebody else's argument by morning.
The work is Solidity and Rust, protocol integration, on-chain data and indexing, and the settlement and reconciliation paths that establish what actually happened.
It is the same engagement as our staff augmentation, with one difference: every path that moves value is walked before it ships, because there is no chargeback behind it.
The reconciliation discipline comes from card rails rather than from crypto. Anupam Shah ran payment infrastructure at $60M+ volume in MAS-regulated, SOC 2 / ISO 27001 environments.
Who writes a given engagement is named in the proposal, not on a website. What is fixed is who reads it before it merges.
We are engineers, not auditors. We do not issue audit reports or security sign-off. When a contract needs a formal audit we say so and name a firm that does that work.
Chains, contracts and the value paths, in writing
Simulated before it is broadcast
Read before it merges
The accent sits on review because that is where hired blockchain work fails when it fails: the code was written, and nobody accountable read it.
Scope
Smart contracts in Solidity; protocol integration, indexers and execution paths in Rust where correctness and latency justify it; TypeScript where they do not. Blockchain developers for hire are usually sold by language.
We scope by the value path the code touches, and pick the language second.
Before any contract or payout path ships, every route by which value can leave is listed, simulated against forked mainnet state, and signed off by a person.
Reorgs, stale RPC state, decimals assumed rather than read, a retry with no idempotency key — the boring failures are the expensive ones, and they are the ones checked first.
The unit you are buying is reviewed output, not a seat. Work lands in your repository checked, with the reasoning written down, and one named principal is accountable for what merged.
Not a coordinator, not an account manager, not a rotating reviewer you have never met.
Everything is written inside your repository and assigned to you in the contract. No key material of yours is ever held by us.
The simulation harness and the reconciliation checks are yours to run after we leave, so a change six months from now can be evaluated without a phone call to us.
No audit reports or security sign-off, no token or tokenomics design, no fundraising, no market making, no custody of funds, no financial advice. Engineering only.
Each of those is a different profession, and a firm that claims all of them is selling you something it cannot do.
Bring the chain, the contracts and the thing you need built. On the first call we walk the paths that move value and tell you what the work needs. Sometimes that is a smaller job than you arrived with.
Scope goes in writing with a fixed fee, a deposit clears, and work lands in your repository reviewed. There is no interview loop and no résumé stack, because the unit you are buying is reviewed output rather than a person.
A fixed fee against a written scope, never an hourly rate, and never a seat price. The scope is what sets the price, and the scope is written after we have walked the value paths with you, not before.
If the honest answer is that a formal audit or a configuration change covers your problem, you hear that first.
Yes. A single contract is a normal engagement shape here, and often the right one.
Hire smart contract developers for one contract and you should still get the full treatment: the value paths listed, the change simulated against forked state, retries made idempotent, and a person reading the diff before it merges.
A small contract that moves value is not a small risk.
No, and you should be wary of anyone who says they do. Writing and auditing the same code is the conflict a formal audit exists to remove.
We build, we harden, we simulate, and when a contract needs an audit we say so and name a firm that does that work. The audit is a referral, not a line on our invoice.
You own the code: it is written in your repository and assigned to you in the contract.
You hold the keys: no private key material of yours is ever in our hands, and any signing path we build hands the transaction to a signer you control.
When the engagement ends, the simulation harness and the reconciliation checks stay with you and run without us.
Ask any shortlist who reads the code before it merges, and whether that person's name is on the contract.
The discipline on this page was learned on payment rails, where a wrong write has a chargeback attached; on a chain it does not, so the same habits matter more.
We lead with AI implementation; on-chain work sits beside that line because it is the same discipline with worse recovery.
Nobody before an NDA. Access is read-only until scope is signed, and you can revoke it at any time. Most implementation is AI-assisted and every change is reviewed by a person before it reaches your branch.
Which tools see your code, and what they retain, is stated on the governance page.
Retainers end on 30 days written notice from either side, with no minimum term underneath. Milestone billing means you are never paid up ahead of delivered work. Written scope means you knew what you were buying.
Once scope is signed and the deposit clears, quickly. We do not quote a start date before that, because a date given before scope exists is a date that moves. We never start on a verbal agreement.
