PingMe

PingMe is a stablecoin payment tool on Monad that turns a transfer into a claimable link or QR code: the sender sets an amount and currency, and the recipient opens the link and enters a phone number or email to collect, without installing a wallet first. It serves people collecting small sums in social settings, such as splitting bills, tipping content or selling at a stall, where the counterparty often has no on-chain account and will not set up a seed phrase and gas for a single payment.

On the mechanics, the contract issues a one-time claim voucher and locks funds in escrow, with the amount, expiry and number of claims encoded, while the key inside the link only proves the right to claim. When the recipient first opens it, a relayer pays gas, a custodial account is created after a single signature, and funds land there directly. Unclaimed vouchers return to the sender at expiry, who can also revoke at any time. Batch links support splitting, and a custodial account can be upgraded to a self-managed wallet that keeps the same address after the key is exported.
