Ink claim costs: Tokenry fee and gas in ETH
The Tokenry fee on Ink is 0.0015 ETH per claim from a position in your wallet, and each claim covers one position.
Gas is extra, paid in ETH, and varies with network use. On Ink it has 2 parts: execution, and a security part that pays for publishing Ink transactions to Ethereum (Ink's transaction fee docs).
You pay the Tokenry fee inside the claim transaction. If that transaction fails on-chain, it reverts as a whole, so you pay no Tokenry fee, but the gas is still spent. If the claim is likely to fail, the review warns you before you sign.
