Server instructions

UNRENT returns overpaid rent from Solana token accounts. SIMD-0437 lowers lamports_per_byte in five steps; existing accounts keep their old, higher deposit until it is withdrawn. Flow: scan_wallet (read-only) -> build_reclaim (unsigned transactions) -> the wallet signs -> submit_reclaim. UNRENT never sees a private key. If you cannot sign for the wallet (its keys are in the user's browser wallet), give the user the signUrl from scan_wallet instead: they finish the reclaim on unrent.xyz. Show the user the net amount and the service fee before asking them to sign. Tokens are never touched unless the user explicitly asks to burn dust; then pass those accounts in build_reclaim.burn. Signed transactions must arrive within about 60 seconds of build_reclaim. If submit_reclaim reports an expired blockhash, call build_reclaim again.

Known tools 4

get_rent_status

Where Solana's rent reduction (SIMD-0437) stands: the live lamports_per_byte, which of the five steps are live, and when the next is expected.

Inferred read-only

scan_wallet

Reads 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).

Inferred read-only

build_reclaim

Re-scans the wallet on the chain and builds the reclaim as unsigned, simulated Solana transactions (base64, versioned).

Inferred read-only

submit_reclaim

Checks the signed transactions against the ones build_reclaim made (same instructions, same fee, signed by the wallet) and sends them to Solana.

Inferred read-only
