Solana program architecture
Solana is built as a program that derives new accounts for its supported tokens.
Solana architecture simplified
The program supports the following instructions:
// wrap fluid token
Wrap(u64, String, u8),
// unwrap fluid token
Unwrap(u64, String, u8),
// payout two accounts
Payout(u64, String, u8),
// initialise solend obligation account
InitSolendObligation(u64, u64, String, u8),
LogTVL,
// initialise the data account for this token
InitData(String, u64, u64, u8, u64, u64),
// move from prize pool to account
MoveFromPrizePool(u64, String, u8),
// update mint limit to an amount
UpdateMintLimit(u64, String),
// update the payout restriction limit
UpdatePayoutLimit(u64, String),
// update the payout authortity (the rng oracle)
UpdatePayoutAuthority(String),
// update the operator (the multisig)
UpdateOperator(String),
// confirm the payout authority in the two step replacement process
ConfirmUpdatePayoutAuthority(String),
// trigger emergency mode
Emergency(String)
- 1.Using Solend, the program deposits the user's given amount as liquidity
- 2.The program determines the collateral account from Solend
- 3.The program stores the collateral in the obligation account for the token
- 4.Using the SPL token, user tokens are minted proportionate to the amount deposited
- 1.Contract burns the user's SPL tokens
- 2.Refreshes the Solend reserve
- 3.Calculates the Solend collateral amount in the obligation account
- 4.Withdraws from Solend to the user's token account
