About the service
I write and optimize smart contracts in FunC for the TON blockchain — from a single message handler to a full-fledged protocol. FunC is a low-level C-like stack language for TON that compiles to Fift and TVM assembler, so I work close to the metal where gas and cell layout really matter. Need a token, custom wallet, escrow, vesting vault, marketplace or DEX pool — I'll design a suite of contracts, a message exchange scheme between them and a storage structure, then implement it all carefully.
What you get: production-ready FunC sources with clear structure and comments; implementation of Jetton per TON token standards (minter plus wallet) or your own design of fungible or non-fungible token; handlers for internal and external messages with proper bounce processing; op-code routing; a set of get-methods so frontend and indexers read state without extra requests. I pay attention to cell and slice work, reference depth and contract exit codes, because in TON sloppy layout is a constant tax on gas in every transaction.
Each contract comes with a test suite. I run scenarios in a local TVM sandbox: normal paths, broken messages, retries and calls from unauthorized senders, and measure gas per operation so you know the real cost before mainnet. I'll hook up deployment scripts, a build pipeline in Fift or TypeScript and a thin client without extra dependencies so the team calls the contract from Node or browser. I also review existing FunC code, hunt for message races, fix storage fee leaks and tighten hot spots in TVM assembler. Send a specification or repository link — I'll estimate scope, describe exit codes and deliver contracts you won't be ashamed to audit.
