OptionFlow

Smart contracts that survive mainnet — real users, real money, no patches.

We build contracts, dApps, and launches that work in production, not just demos. Tested Solidity, pre-deploy review, usable frontends. On-chain bugs are permanent — we deploy like it.

What you get

  • StackSolidity, EVM chains, TypeScript
  • TestingFull test suite per contract
  • SecurityPre-deploy review + gas optimization
  • OwnershipYour keys, your repo, your contracts
  • DeliveryTestnet first, verified source, docs

Sound familiar?

  • You have a whitepaper and a deadline, but nobody on the team has shipped a contract to mainnet

  • Your dApp works in the demo wallet and fails the moment a real user connects

  • A freelancer deployed your contract, and you don't know who holds the owner key

  • Gas costs make every transaction feel like a tax on your own users

  • Investors ask about your audit and you don't have an honest answer yet

  • Your token needs vesting and distribution logic no spreadsheet can enforce

What we build

  1. 01

    Smart contracts

    Solidity contracts — tokens, staking, marketplaces, custom logic. Proxy vs immutable decided upfront, owner and admin keys in a multisig ceremony, fork-tested against mainnet state.

  2. 02

    dApps & wallet integration

    React frontends hardened for mainnet: multi-wallet edge cases, chain switching, pending, failed, and replaced transaction states, event indexing, and human-readable errors — never raw hex.

  3. 03

    Tokenomics & token launches

    Supply, vesting, and distribution encoded on-chain — cliffs, unlocks, and allocations that match the counsel-approved whitepaper to the wei, with handover docs investors can verify.

  4. 04

    Contract audits & security

    A line-by-line review before deployment: reentrancy, access control, overflow, oracle manipulation, and gas waste. You get a written report and fixes, not a badge.

How it works

  1. 01

    Discovery call

    Tell us what the protocol or product should do, which chain you're on, and what's already deployed. No commitment.

  2. 02

    Scope & proposal

    A fixed-scope plan with price, timeline, and the contract architecture sketched out — before a single line of Solidity is written.

  3. 03

    Build in sprints

    Contracts and frontend on a testnet every one to two weeks, with demos, test reports, and room to adjust.

  4. 04

    Launch & support

    Final review, mainnet deployment, verified source code, key handover, and a support window so nothing surprises you after the block confirms.
