If the recipient address does not yet have an Associated Token Account (ATA) for that specific token, the transaction creates it. ATA creation requires a one-time rent deposit on Solana (~0.002 SOL).
That rent is converted into the token fee for the first transfer. As a result, the very first gasless send to a brand new address is significantly more expensive than all the following ones.
After the ATA exists, every subsequent transfer only pays the actual tiny network fee + a small dynamic margin.
Call estimateTransactionFee on the same
endpoint with your unsigned transaction and the
fee_token (USDC or USDT mint). It returns
the precise amount that will be charged. No surprises.
Yes. Your transfer instructions and the fee payment are assembled into one Solana transaction. Kora co-signs as fee payer only after validation. The result is atomic: either the full transaction succeeds (transfers execute + fee is paid) or it fails entirely and nothing moves.
