pay3

pay3 is a unified crypto payment link that consolidates all of a user’s wallet addresses into a single, human-readable URL (e.g., pay3.so/@yourname). Its primary purpose is to eliminate errors, friction, and complexity when sending and receiving crypto payments across multiple networks and tokens. Instead of sharing long hexadecimal addresses and checking networks manually, pay3 provides a simple payment page where payers can complete transactions in a few clicks.

The tool offers a POS-style interface that resembles familiar consumer payment apps, allowing payers to enter an amount, choose a token, and send funds without dealing directly with wallet addresses. Built-in smart fee recommendations automatically surface the cheapest supported network for a given token, helping users avoid unnecessary gas costs (for example, suggesting BEP20 instead of Ethereum when appropriate). pay3 also integrates directly with major exchanges and wallets such as Binance and Coinbase, enabling one-click payments from existing accounts. This reduces the risk of sending assets to the wrong network and shortens the end-to-end payment process from several minutes to under a minute.
