I will create ecommerce website to accept crypto payments with custom erc20 solana

Processors like BitPay are notoriously rigid, only offering payment options for Bitcoin, Litecoin, Ethereum, DogeCoin, etc. but no altcoins. With no coding, you can integrate your own processors to add the altcoins that you want to accept, even your own.

For automatic delivery, only ERC721, 721A, or 1155 NFTs can be listed as digital assets (sorry no Solana, etc.) This is because the marketplace contract is written for EVM-compatible assets. You can list anything you want (ebook downloads, etc.) but are responsible for the method of delivery.

The awesome thing about managing a decentralized marketplace is that there is zero accounting needed. Sellers decide what wallet address they want payments to be sent to and when a purchase is made, the payment is transferred automatically.

If you already have a token, you know that your ranking is largely dependent on 24-hour transaction volume. Launching a marketplace in which people transact and pay fees in your token not only adds utility, but helps to increase that 24H-TV. Check out my tokenomics gig if you need more help!

The payment processor currently handles tokens created on EVM-compatible networks (Ethereum, Polygon, Binance, Base) and Solana (SOL, SPL).

No. Bridging is basically the act of transferring one asset on one network to another network (e.g. Ethereum -> Polygon). While you will be able to deploy marketplace contracts to support however many networks you want, users who want to bridge assets should use a bridge service.
