I’m interested in developing a bot for my Discord server that checks if users hold specific cryptocurrency tokens before they gain access to private channels. The plan is to ensure that members can demonstrate they possess a certain amount of tokens in their wallet to join our exclusive group.
I’m uncertain about the technical details. Do I need to use blockchain APIs to verify wallet addresses? How does the verification process function – do users provide their wallet address, and then the bot checks the blockchain?
I also have security concerns. Is it safe to request wallet addresses from users? What’s the best method to conduct the verification without risking anyone’s privacy?
Has anyone created something like this? I would appreciate advice on the overall setup and any tools or libraries that would be useful for a project like this.
i made a similar bot not long ago. the moralis api is gr8 for checking wallets - just gets the public address, which is safe to share. users give their address, and the bot checks the blockchain for you. took me like 2 weeks to sort it all out, but it was worth it!
Been running token-gated Discord servers for over a year. Alchemy API’s been my go-to - free tier is generous and response times don’t suck. Here’s what most people miss: users often split tokens across multiple wallets for security. I let people link up to 3 addresses to their Discord account. Watch out for staked tokens and LP tokens too - your verification needs to catch these if they count toward your threshold. Honestly, Discord was way more painful than the blockchain stuff. Build solid error handling for when the API craps out, or users will rage at failed verifications. Also set up a whitelist as backup when your bot inevitably goes down. Trust me, having multiple verification methods saves your sanity.
You’re definitely on the right track with blockchain APIs. I built something similar with Web3.js and Discord.js about six months back. Works exactly like you described - users drop their wallet address via bot command, and the bot checks the blockchain for token holdings against your minimums. Security-wise, you’re fine asking for public wallet addresses since that’s what they’re for. Just never ask for private keys or seed phrases, obviously. I’d set up role-based permissions so the bot auto-assigns roles after verification passes. Here’s what bit me: definitely add rate limiting and caching. Those blockchain API calls get pricey and slow fast, so cache successful verifications for a while. Also think about what happens when someone’s token balance drops below threshold later - might want to run periodic re-checks.
