Hey Everyone, I’m Ismail, the maker of ChainCheck API. The story behind this product is a bit painful: I recently lost funds on a testnet because I pasted a smart contract address with a single typo. It made me realize that if I can make this mistake while testing, someone else can definitely make it with real money on Mainnet. I looked for a simple API to validate addresses programmatically, but everything was either too expensive or way too limited for an actual product. So I built ChainCheck API. It is a dedicated micro-service to sanitize crypto inputs before they hit the blockchain. What's included: - 120+ Chains Supported: (ETH, BTC, SOL, ADA, and more). - It's simple to use. Just hit the endpoint with the address and chain symbol. - You can test it immediately using the free tier (No Sign up required). I would love for you to try the API and let me know if I missed any edge cases! Thanks
