Introduction
Welcome to VelumX, the premier gasless transaction infrastructure for the Stacks blockchain.Problem Statement
Traditional blockchain applications require users to hold native tokens (e.g., STX on Stacks) to pay for transaction fees. This creates significant friction:- Onboarding Barrier: New users must acquire native tokens before using dApps.
- Poor UX: Users must manage multiple token types for simple actions.
- Adoption Blocker: Limits mainstream DeFi adoption by requiring upfront capital.
The VelumX Solution
VelumX implements a universal paymaster pattern that enables users to pay transaction fees in any SIP-010 token (like USDCx, sBTC, or ALEX) instead of native STX.Stacks-Native
