Transaction re-tracer (step-by-step TVM)

Re-executes a mainnet or testnet transaction in your browser on the exact account state, config and libraries of its block, checks the result is bit-identical to the chain, and shows every TVM instruction with the stack and gas at that step.

Your browser queries public TON APIs (toncenter, tonapi) directly. We run no server in between and store nothing you enter.
