Early access

A swap desk for Solana that lands your trade with adaptive fees and then shows exactly why it succeeded, failed, or cost more than quoted.

Trading tools sell speed and breadth. Landed sells honest accounting: every fee shown before signing and every failure explained after.

Planned

Multi-path rebroadcast until the transaction lands or its blockhash expires.

After you sign, the same transaction is sent over several paths in parallel. Landed keeps resending until it confirms or the blockhash expires, and it never signs a second transaction on your behalf, so you cannot double fill.

Planned

Life of one transaction

Signed in PhantomTransaction is built with a fresh blockhash valid for about 150 slots.

Swap desk with pre-trade simulation, adaptive priority fee, and a hard slippage stop.

Every swap is simulated against current chain state before your wallet is asked to sign. You see the expected output, the priority fee Landed picked, and the slippage stop that will cancel the trade if the real output drifts past your limit

Planned

Results appear here.

Fee autopsy on every trade: all costs itemised, plus quoted versus received price.

Each landed trade gets an itemised receipt: network fee, priority fee, tip, any account rent, and the gap between the quoted price and what you actually received. Nothing is folded into the rate.

Planned

Autopsy: 2.5 SOL to USDC, 14:52

Item	Amount	Note
Base fee	0.000005 SOL	One signature
Priority fee	0.000210 SOL	Set from recent slot fees
Block engine tip	0.000100 SOL	Used on attempt 1 path
Token account rent	0 SOL	USDC account already exists
Quoted price	168.40 USDC	At simulation time
Received price	167.95 USDC	Difference 0.27%, 1.13 USDC

Failure reports that decode the error into a plain reason and a suggested fix.

When a trade fails, Landed reads the program logs and error code and tells you what happened in a sentence, then suggests a specific change such as a wider slippage limit or a smaller size.

Planned

Failure report: 45 USDC to JTO

Why did my JTO swap not go through?

The transaction was sent on 3 paths and resent 4 times, but it was not included before its blockhash expired at slot 3 slots past your last attempt. Nothing was charged.

Cause: priority fee of 0.000090 SOL was below the level needed during a busy window. Suggested fix: retry with the adaptive fee set to High, which would be about 0.000340 SOL.

Execution API with the same receipts for bots and agents, using the caller's own signing key.

The execution API returns the same simulation, landing status, autopsy and failure report as JSON. Your bot signs with its own key. Landed never holds it and only receives the signed transaction.

Questions.

Short answers. The docs have the rest.

What is Landed?

A swap desk for Solana that lands your trade with adaptive fees and then shows exactly why it succeeded, failed, or cost more than quoted. Trading tools sell speed and breadth. Landed sells honest accounting: every fee shown before signing and every failure explained after.

What works today?

Landed is in development. Every feature is on the status list with what ships next, and the app opens in a sample workspace so you can see how it will work.

Do I need a wallet?

No. You can explore without one. Connecting a Solana wallet only shares your public address so Landed can read your balances; it never asks you to sign a transaction.

Who is it for?

Active Solana traders, small funds, and bot or agent builders who care about landing rate and true cost per trade.
