Building Text-to-Pay for Crypto

Product prototype

Mar 30, 2026

A prototype for sending crypto payments via text, without wallet intricacy.

Sending crypto still asks people to think about addresses, networks, gas, and wallet state before they can do the simple thing: send money.

I studied UX flows for Venmo, Cash App, Base, and Phantom, then prototyped messaging-first flows across Solana and Base with smart-wallet and gas-paymaster patterns in mind.

The goal was to reduce wallet anxiety: hide gas choices, make recipients easy to verify, and make failures recoverable.

Highlights

  • Matched familiar payment patterns to crypto-specific needs.
  • Explored Solana and Base flows without locking the concept to one chain.
  • Designed for senders who should not have to parse wallet mechanics.
