Hello,
because atlos uses smart contracts, only evm compatible chains will be supported for now?
gas fees for bsc and polygon are fine. but for eth main chain, the gas fee may be astronomical, can you tell me how much gwei would cost the client for it to complete the transaction?
Hi tesloga,
Welcome to the forum.

Actually, on non-EVM compatible blockchains, we use a different method to detect payments. So, we support other blockchains too. Here’s a list of all supported blockchains and coins/tokens:

It costs as much as making a regular payment on a particular blockchain. This is the beauty of our system. You never have to worry about miner fees, because the end-users (your buyers) pay for them. When someone makes a payment, it goes directly from the user’s wallet to your wallet. There is no need to pay for any extra miner fees.
This fee amount varies depending on the blockchain, size of the transaction, and how many transactions are currently in the mempool. I won’t go into technical details here, but here’s an example of current gas price tracker for Ethereum:
Thanks. Is there any restrictions regarding use cases? My website would be involving AI porn, would that matter?
Is the smart contract verifiable? Can the payments accumulate and then get withdrawn at once, to minimize the block fees?

No, we do not have any restrictions for use cases or industries.

Payments are sent directly to your wallet, so “withdrawing” is not a thing 
In other words, each payment settles immediately. You do not have to withdraw it or pay any fee for that.
also, how does it work with bitcoin, litecoin etc? smart contracts on ethereum related chain could obviously be non-custodial, but for those?
Good question. We worked a lot on it actually. For non-EVM blockchains we use different methods to detect payments:
If the merchant entered a wallet public key, we generate a unique wallet address for each payment
If the merchant address is always the same, we vary the payment amount slightly (for a fraction of a cent) when multiple payments are expected at the same time
Lastly, if a user sent a wrong amount (or even a wrong coin or on a wrong blockchain), we have a comprehensive recovery mechanism that allows users to apply the payment correctly
