marginfi accounts (Project 0)

Find accounts with positive asset shares in marginfi’s Solana lending program. The official marginfi app now directs users to Project 0 to manage active positions. This check identifies recorded assets, but does not calculate token amounts, net equity or a withdrawable balance.

The program ID, account layout, official migration page and public mainnet accounts were checked. Interactive management and withdrawal steps have not been tested in the app.

What it is

marginfi stores deposits and borrowing in separate accounts owned by its lending program. An account may retain asset shares after you stop using it. Those shares need bank exchange rates to be converted into token amounts. Borrowing, account health and liquidity can limit withdrawals.

Who is eligible

The scanned address must be the authority of a MarginfiAccount in program MFv2hWf31Z9kbCa1snEPYctwafyhdvnV7FZnsebVacA. Group membership or a similarly named receipt token does not establish ownership.

The check uses the 2,312-byte layout and authority at byte 40. It inspects active balance slots for positive asset shares and distinguishes borrowing shares and accrued borrowing premiums. The layout comes from the official account types. Accounts with only borrowing produce an informational notice, not a finding of recoverable funds.

Up to 500 accounts are inspected. An invalid or truncated response is reported as an error or an incomplete result. The check does not calculate bank values, liquidation risk, pending external rewards, cross-protocol positions or refundable account rent. Unknown amounts and values are excluded from the USD total. Small share balances may be dust.

How to get it out

1. Read the official marginfi migration page. It links to the Project 0 app at https://app.0.xyz for managing active positions.
2. Review the complete account address shown in the report in the official app. DeFi Checkup never requests a wallet connection or signature.
3. Check the account’s actual token amounts, borrowing, net equity, health and any restrictions. A finding with asset shares does not establish that any amount can be withdrawn today.
4. Follow the app’s current withdrawal or repayment flow only after reviewing those conditions. Check every asset, destination and fee in a trusted wallet before signing.

What it costs

Unknown here. Withdrawal or repayment may need multiple instructions, protocol fees, priority fees or additional operations to keep the account healthy. No complete transaction was simulated or sent.

Deadline

No recovery deadline was identified in the reviewed sources. Program upgrades, account restrictions, liquidations and market liquidity can affect recovery even without a fixed deadline.

How to check

Scan your address without connecting a wallet or signing. Review borrowing notices and any incomplete results before using the official app.

FAQ

Does a finding mean the account has positive net equity?

No. The check proves positive asset shares, while borrowing can offset those assets. It reports borrowing separately and leaves token amounts, net equity and USD value unknown.

Where is the official app now?

The official marginfi app displays a migration page that links to Project 0. Start from that page and review the complete account address before managing a position.

Does an empty marginfi account mean refundable rent?

This check does not establish closure eligibility or count account rent. It only identifies positive asset shares and notices borrowing in the supported account layout.
