Notifications
Notifications are special functions that are triggered when the system contract receives a message from an external contract
Transfer
When the contract receives a transfer action notification it first checks if the transfer is coming from the token.boid contract or the atomicassets contract and that the parameters are valid.
If the deposit is tokens from token.boid then it checks the memo to determine what kind of deposit to process. If the memo starts with "sponsor" the funds are directed to the deposit table. If the memo starts with "deposit" the funds are diverted to a boid account liquid balance. To determine what boid account should receive the BOID, it checks the memo for "boid_id=boidid". If the boid_id supplied is valid, then that boid account is credited for the deposit.
If the deposit is an NFT transfer from atomicassets then it makes sure the NFTs are issued by nft.boid and it reads the memo "boid_id=boidid" to determine which boid account should be credited with the NFTs. New rows are added to the nfts table.
logmint
When the contract receives a logmint action notification it makes sure the mint is coming from the atomicassets contract and issued by nft.boid. Next it checks the nftmint table to see which boid account should be credited with the newly minted NFT. The nft is then added to the nfts table and the account nft_balance is incremented.
