Translation Quality Review

Language: Czech (cs)
Files reviewed: 24 (all files spot-checked; 10 files read in full detail)
Model: Claude Opus 4.6

Quality Score: 7/10

Category	Score	Notes
Brand Name Preservation	10/10	Solidity, MetaMask, Ethereum, Hardhat, Alchemy, etc. all correctly preserved in English
Technical Accuracy	6/10	Strings inside code blocks (require(), console.log, alert, test descriptions) were translated -- fixed in commit c6a60ed
Naturalness & Fluency	8/10	Czech reads naturally and fluently; good idiomatic phrasing throughout
Terminology Consistency	8/10	Consistent use of "chytrý kontrakt", "transakční poplatky" (for gas), "peněženka", "uzel", etc.

Issues Found

Fixed (commit c6a60ed):

1. Translated code strings in 8 files -- String literals inside code blocks (Solidity require() messages, JS console.log(), alert(), test it() descriptions) were translated to Czech. These are executable code that developers would copy-paste, and translating them changes program behavior or breaks code. Restored all to original English.
   • how-to-use-slither-to-find-smart-contract-bugs/index.md -- "nej pokročilejší" (split word artifact) and "početkrát" (merged word artifact)
   • how-to-write-and-deploy-an-nft/index.md -- console.log("Kontrakt nasazen na adresu:", ...) and translated package.json test script
   • send-token-ethersjs/index.md -- alert("Odesílání dokončeno!") and 3 other alert() strings
   • interact-with-other-contracts-from-solidity/index.md -- 2 require() messages (x2 occurrences each)
   • sending-transactions-using-web3-and-alchemy/index.md -- 2 console.log() strings
   • short-abi/index.md -- 2 require() messages, 3 console.log() strings, 1 it() description
   • optimism-std-bridge-annotated-code/index.md -- 4 require() messages
   • scam-token-tricks/index.md -- 7 require() messages

Not fixed (minor, acceptable):

• Code comments in Solidity/JS blocks are translated to Czech. This is acceptable as comments are for comprehension and don't affect code execution.
• Hardhat CLI output and npm init prompts in how-to-write-and-deploy-an-nft are translated for reader understanding. These are illustrative, not executable.

Summary

The Czech translations are fluent and natural with excellent brand name preservation. The main issue was Crowdin translating string literals inside code blocks, which would produce broken code if developers copy-pasted the examples. All critical code strings have been restored to English. Two minor Crowdin word-splitting artifacts were also fixed.
