This directory contains tools for the contract size minification. Requirements: * cargo install wasm-snip wasm-gc * apt install binaryen wabt

WARNING: minification could be rather aggressive, so you must test the contract after minificaion. Standalone NEAR runtime (https://github.com/nearprotocol/nearcore/tree/master/runtime/near-vm-runner) could be helpful here.

Current approach to minification is the following: * snip (i.e. just replace with unreachable instruction) few known fat functions from the standard library (such as float formatting and panic related) * run wasm-gc to eliminate all functions reachable from the snipped functions * strip unneeded sections, such as names * run Binaryen wasm-opt, which cleans up the rest
