get_rent_statusread-onlyWhere Solana's rent reduction (SIMD-0437) stands: the live lamports_per_byte, which of the five steps are live, when the next is expected, and whether a step is already queued on chain (it then activates at the next epoch boundary). Older accounts keep their higher deposit until it is withdrawn; each step makes more SOL reclaimable.
scan_walletread-onlyReads the token accounts and mints of a Solana wallet and returns the SOL that can be reclaimed now: excess rent (WithdrawExcessLamports, accounts stay open), empty token accounts (CloseAccount) and mint excess, the UNRENT service fee, the net amount, a forecast for the remaining rent steps, and tokens that may optionally be burned and closed (dust). Read-only, needs no signature. Amounts are in S
build_reclaimRe-scans the wallet on the chain and builds the reclaim as unsigned, simulated Solana transactions (base64, versioned). They withdraw excess rent, close empty accounts and pay the service fee as the last instruction; nothing else leaves the wallet. Tokens are only burned for accounts listed in `burn`. The wallet's owner signs every transaction unchanged (the fee payer is the wallet, compute budget
