hey guys dropped out at 16 to build in crypto. 8 years later, we still share wallet addresses like it's 2015. 0x742d35Cc6634C0532925a3b844Bc9e7595f8bE2e imagine sending this to a client. imagine getting it wrong by one character. built pay3 because i got mass of people complaining about this. now it's just: pay3.so/@varun client clicks. picks USDT. pays. done. --- for the technical folks: - non-custodial (we never touch funds) - multi-chain (eth, tron, solana, bsc, polygon) - walletconnect v2 - telegram bot for notifications --- what we're not: - not a wallet - not an exchange - not asking you to "connect wallet" before seeing anything --- this is my side project. built it, learned a lot, sharing it with you all. roast the UX if needed. genuinely want feedback. try it: pay3.so mine: pay3.so/@varun happy to answer anything below 👇

clean stack. curious how you're handling multi-chain address detection?

@yednap868 it's pattern-based detection, pretty straightforward actually.


0x + 42 chars -> EVM (works across ethereum, bsc)

T + 34 chars -> Tron

44 char base58 -> Solana

one EVM address covers multiple chains automatically. user adds one address, we map it to all compatible networks.

no blockchain queries needed at detection time - just regex matching on input.
