Tollcraft

Profile Soroban (Stellar) contract WASM locally: Instruction & fuel costs, runaway loops, CI budget checks. Cut on-chain compute before mainnet.

[Tollcraft @tollcraft_dev]

1/ Soroban contract cost is invisible until you’re on-chain and paying for it.

Tollcraft is three open-source tools for Stellar smart contracts: lint at compile time, assert at test time, profile when a budget breaks.

Here’s how the pipeline works 🧵

Stop guessing your gas bill.

A Soroban tx dies on BudgetError and nothing tells you which line ate the budget. Tollcraft profiles your contract WASM locally, instruction by instruction, mapped back to the Rust source.

Most Soroban devs learn what their contract actually costs only after it's live and users are paying for it. We got tired of that. So we built Tollcraft a profiler that shows instruction + fuel cost locally, before you deploy.

i maintain @tollcraft_dev — a Rust profiler for Soroban contract WASM. Runs your contract locally, reports instructions + fuel usage per function. No node needed. Ship cheaper compute. Fully open source, and contributors welcome. Come build with us @BuildOnStellar @StellarOrg

7/ Prevent → detect → diagnose. Each tier catches a failure the others miss, so every instruction is accounted for before mainnet.
