How LANDED works

We cannot guarantee that a transaction will succeed. We guarantee that you do not pay for it if it fails.
We never hold your funds. We can only send the exact transaction you signed. There is no approval to us and nothing to revoke.
If you go over your failure budget for the day, we stop sending for you until the next day. The counter is shown in your activity.

The mechanism

Every Solana transaction names a fee payer. In a LANDED transaction the fee payer is our relayer, not you. That is a native feature of Solana: there is no LANDED program on chain, nothing to approve and nothing to delegate.

You ask for a sale or a transfer. The relayer builds the transaction and hands it to your wallet. Your wallet shows what it does, and you sign it. The relayer can send it or not send it. It cannot edit it: your signature covers every byte.

The fee is a USDC transfer inside that same transaction. A transaction is atomic: if the swap fails, or the price moved past your limit, nothing in it happened, the fee included.

The relayer simulates right before sending and refuses what would fail. When a transaction still fails on chain, the network fee is ours.

Fees

Fixed per action, in USDC, written into the transaction you sign. A failed transaction costs you zero. If a token account has to be opened (your USDC account, or the recipient’s), its rent is added at cost and shown before you sign. The fee table served by the relayer is signed.

Limits

A new account can have one transaction in flight and ten per day. Limits rise automatically as you land paid transactions.
Each account has a daily budget of failed sends. Past it, we stop sending for that account until the next UTC day.
If the global failure rate crosses a threshold, the relayer stops sending for everyone and says so.
A signed transaction is valid for about one minute. After that it can never land.

Which wallets work

Any Solana wallet that can sign a transaction without sending it: Phantom, Solflare, Backpack and most others. The wallet needs no SOL. Sales pay out in USDC; sending a token needs a little USDC in the wallet for the fee.

Leaving

There is nothing to leave. LANDED holds no approval, no delegation and no deposit. Close the tab and your wallet is exactly as it was.

Risks you should know

LANDED is new software and has not been audited by a third party. Read what your wallet shows before you approve.
Swaps are routed through Jupiter and the pools it uses. A token with thin liquidity can sell for less than its quoted price, down to the minimum shown before you sign.
USDC is controlled by its issuer, which can freeze accounts.
