a marketplace or an infrastructure to monetize solana programs. focussing on both buyers and sellers is crucial to create a fair market. so this uses PDA and not spl-token(which is the norm in marketplace). this is intentional. this avoids trading program access which affects the sellers in the market. and buyers are protected by provided a trial period with a minimal cost when they can test the functionality and usefullness for thier application.
- open a pda account with program id, seller pubkey as seeds with before mentioned details with amount stored in the struct.
- since transations are atomic in nature in solana, we can utilise it by including both the instruction in a single transaction
- and the two instructions are
- transfer amount which depends on trial or permanent access
- create access pda
- open a access pda is done by feeding buyer pubkey, program id into the seeds and a acc struct with all the details mentioned before with amount and expiry is created
In IDE
- add the macro provided by the commute market place in the acc intialization in your solana program
- upload ur program to the solana block chain
In Commute
- login in to commute with your wallet and create a seller program with program name, description, amount and program id
- and voila seller program is created in commute marketplace ready to be bought.
In Commute
- login to commute with ur wallet
- visit the seller program list and look for the solana program which best suites ur needs
- click to see the complete info of the seller program, if needed can verify everything in block explorer with the seller program pda
- once satisfied, choose trial or permanent access.
- go ahead buy the access pda. which will intiate a sol transfer to the seller pubkey and also create the access pda
In IDE
- to access the methods provided buy the seller program, we need to pass the access pda while invoking the functions.
- which does the relavent checks and validates the buyer
