Do credits expire?
No, credits never expire. Use them whenever you need.
What happens if I run out of credits?
Mainnet wallet adapter transactions will fail until you top up. Testnet always works for free. Script Composer is unaffected since it doesn't use credits.
Does Script Composer use credits?
No. Script Composer deducts a small fee directly from the token being sent — no credits required. Credits only apply to wallet adapter transactions on mainnet.
Can I get a refund?
Unused credits can be refunded within 30 days of purchase. Contact contact@smoothsend.xyz.
