QTC Swap Desk
NEAR Intents is Quantus's first exchange venue — and the official wallet already ships a two-way swap flow for it. The only missing piece is the listing itself: QTC isn't on Intents yet. This desk watches the live 1Click token list for the moment that changes, and meanwhile lays out exactly how the swaps will work — the real steps, the real fee math, the real failure modes — sourced from the wallet team's own integration docs.
Probing the live 1Click API…
Live listing watch
Asking the 1Click API for its token list.
What flips on listing day
- This card turns green and shows QTC's decimals + live USD price from the listing.
- The wallet's swap screen (behind its
enableSwapflag) starts returning real quotes instead oftokenIn is not valid. - Solvers can bid on QTC intents — that is when liquidity actually exists, not before.
The watch reads GET https://1click.chaindefuser.com/v0/tokens — the same public list the wallet reads. No API key, no account. A listing appearing here is necessary for swaps, not sufficient for deep liquidity: quotes still come from a solver auction.
How a swap will work
Fee & slippage lab
illustrativeThe 1Click platform fee lives inside amountOut — nothing is charged on top of what you send. Slippage sets your guaranteed minimum. Plug in a hypothetical solver offer and see what the documented parameters do to it. This is not a quote. Real quotes come from the live solver auction, which only runs once QTC is listed.
If a live quote guarantees less than the minimum you reviewed, the wallet shows the new terms and asks you to confirm again — it never silently accepts a worse price.
Order status lifecycle
After the deposit, the wallet polls GET /v0/status every 5 seconds. Click any state to see what it means and who acts next.

Deadlines, refunds & safety rules
⏳ Deposit deadlines
A live quote reserves its deposit address until deadline — the wallet requests now + 20 minutes and refuses any quote whose deadline is under 5 minutes away. Slow chains get more room: 2 hours from BTC, LTC, DOGE, BCH, DASH and ZEC.
↩️ Refund paths
Deposit less than quoted: refunded to refundTo after the deadline, minus a refundFee (0.30 USDC on ETH in the live probes). Deposit more: the swap still executes and the excess goes to refundTo. No fill or price past slippage: REFUNDED.
🔏 Tamper-proof quotes
Every quote carries an Ed25519 signature from the 1Click manager key. The wallet verifies it, checks the echoed request repeats your amount, assets, addresses, slippage and deadline, and rejects anything that doesn't match — a SwapQuoteIntegrityException, not a silent accept.
📬 Addresses are validated early
1Click validates refundTo against the origin chain at quote time, so a bad refund address never reaches the deposit step. Swapping out of QTC, the wallet itself signs the deposit transfer — only transparent accounts whose key lives in the app can swap; encrypted, Keystone and watch-only accounts see the button disabled.
🗂 Orders aren't persisted (yet)
Close the progress screen and the app forgets the order — a swap-in's deposit address lives on in your other wallet, a swap-out's deposit shows as an ordinary transfer in activity, and 1Click keeps processing regardless. Save the deposit address yourself if you navigate away.
🧪 No testnet for Intents
There is no NEAR Intents testnet — the wallet team's docs were verified against the live API. Until QTC is listed, every quote attempt fails with tokenIn/tokenOut is not valid, and the swap UI stays behind the enableSwap remote flag.
