Blockchain Ecommerce

Looking to build a blockchain system for transaction processing, loyalty/rewards, lend/lease, and staking for ecommerce systems. I would want a native token, a rewards token, and a swap site. I would prefer it be built on Solana or Avalanche.

Basically this would be an alternative payment gateway for ecommerce transactions as well as a store of value for sellers/suppliers to be able to resolve invoices on-net through smart contracts. This would avoid ACH or Wire fees and allow for near-instant settlement.
