No Gas Fees or Native Tokens Required

Two key benefits set Stackup apart:

  1. We pay all gas fees across every blockchain

  2. Fees are paid in the transferred token, not in native gas tokens

This means:

  • No need to hold ETH, MATIC, AVAX, or other gas tokens

  • No failed transactions due to insufficient gas

  • No exposure to gas price volatility

  • Simplified treasury management and accounting
