There are two fees associated with each issuance of a Civic Pass:
1) Blockchain transaction fees are defined by the network and may also vary with network congestion. This cost doesn't go to Civic, it goes to the miners that maintain the blockchain.
2) The cost per issuance of each Civic Pass:
CAPTCHA $0.05
Liveness $0.15
Uniqueness $0.30
Please ensure you have enough funds in your wallet to cover the Civic Pass fee and the transaction fees. You can also check which blockchains are supported by the dApp first to see which of the supported blockchains have the lowest fees.
