Before your first payment on EVM or Tron chains, your source account needs to grant permission for the Atum contracts to move tokens on your behalf. This is a one-time on-chain transaction per wallet and token — you don’t repeat it for every payment. Think of it like enabling autopay: you authorize once, and subsequent payments can proceed without re-approving.

​
When you need to do this

  • First time sending a given token from a given wallet on an EVM or Tron chain
  • After switching to a new wallet
  • Not required on Solana (different token model)
