-[Fast](./Performance.md)
+Performs proper input validation, ensures no garbage-in-garbage-out
 
-Performs proper input validation
+Tested on Node.js, Deno, Bun, browsers, Hermes, and barebone engines in CI [(how?)](https://github.com/ExodusMovement/test#exodustest)
+
+## Fast
+
+* `10-20x` faster than `Buffer` polyfill
+* `2-10x` faster than `iconv-lite`
+
+The above was for the js fallback
+
+It's up to `100x` when native impl is available \
+e.g. in `utf8fromString` on Hermes / React Native or `fromHex` in Chrome
+
+Also:
+* `3-8x` faster than `bs58`
+* `10-30x` faster than `@scure/base` (or `>100x` on Node.js <25)
+* Faster in `utf8toString` / `utf8fromString` than `Buffer` or `TextDecoder`/`TextEncoder` on Node.js
+
