Sponsoring types

depo.to supports the following types of sponsoring:
  • ALL: depo.to fetches the current quote for the swap to the target asset and ensures the user receives the same amount, without slippage, price impact, gas fees, or bridging fees. All fees are deducted from the sponsor account.
  • STABLES: depo.to credits stablecoins in the same currency group in a 1:1 ratio.
  • SAME_ASSET: depo.to credits the same asset in a 1:1 ratio.
  • NONE: Default option where none of the fees are sponsored
