Trading Hub — Swap, Fixed & Convert

Swap routes through OpenOcean for best-price execution. Fixed trades at our desk's fixed price with zero slippage. Convert chains two fixed legs (token → CFX → token).

Open /swap →
  1. Connect your wallet, then confirm you are on BNB Smart Chain (chain 56). Every tab guards this before signing.
  2. Swap tab: pick From/To, enter an amount, review price impact + slippage, then confirm. Approve the token first if asked.
  3. Fixed tab → Buy/Sell: pick the pay token, enter an amount, wait for the exact quote, then confirm. The desk reverts if the fill comes back smaller (stale-quote protection).
  4. Fixed tab → Convert: pick From and To (two different tokens), enter an amount, review the two-leg preview, then confirm Step 1 (buy CFX). After Step 1 lands, review the fresh Step 2 quote and confirm Step 2 (sell CFX for the target).
  5. Optional: paste a referral address to share commission with the referrer.

GOOD TO KNOW

  • Convert is two separate on-chain transactions — you hold real CFX between legs. If Step 2 can't fill, you keep the CFX and can resume later.
  • “Desk cannot fill this size” means payout inventory is short — reduce the amount or try another token.
  • All trades are non-custodial: funds never leave your wallet until you sign.

Convert details (two-step)

Convert = Buy CFX with token A, then Sell CFX for token B. Each leg is quoted and executed separately.

Open /swap →
  1. Step 1 uses buyWithBNB / buyWithToken with the leg-1 minOut as slippage protection.
  2. After Step 1 confirms, the app fetches a fresh leg-2 quote off the actual CFX received — never the pre-trade estimate.
  3. Step 2 uses sellForToken with the fresh leg-2 minOut. Both legs record to your trade history.

GOOD TO KNOW

  • Closing or refreshing between legs is safe — Step 1 already settled and the CFX is in your wallet.
  • If the desk's payout inventory moves between legs, Step 2 may need a smaller amount or a later retry.

NFT holdings

Your DN404 mirror NFTs (token IDs) with Alchemy-backed backfill, delta refresh, and on-chain ownership checks.

Open /nft →
  1. Connect the wallet that holds CFX/NFTs. Holdings load from cache, then delta-refresh.
  2. Use Rescan if you just transferred — it forces a full Alchemy backfill.
  3. Sending an NFT: confirm in your wallet, wait for the receipt, then the grid removes it optimistically and verifies against the chain.

GOOD TO KNOW

  • If a token still shows after sending, wait ~5 minutes (grace window) then Rescan.
  • Artwork is served locally as 1–44.gif mapped from token ID, with fallback to 1.gif.

Products store

Browse pay-token priced products, filter by category/price, and buy on-chain.

Open /products →
  1. Filter by category, price band, or featured; sorting and counts update from the URL.
  2. Open a product for full details, related items, and facts panel.
  3. Buy with the listed pay token — approve first when asked, then confirm.

GOOD TO KNOW

  • Sale inventory is checked live via balanceOf before you can buy.

Services

Service listings with banners, categories, and contact actions.

Open /services →
  1. Browse rails or filter by category; zero-count categories are hidden.
  2. Open a service for banner, description, features, and contact buttons.
  3. Use the on-page contact actions to reach the provider.

GOOD TO KNOW

  • Banners adapt to any aspect ratio (blur-fill + contain) — uploads up to the configured limit.

Games

16 seeded on-chain games with presets; play from the Games hub.

Open /games →
  1. Open Games, pick a title, follow the per-game panel to stake/play.
  2. Confirm each move in your wallet and track results on BSCScan.

GOOD TO KNOW

  • Presets are idempotent seeds — replaying the seed never duplicates.

Staking & vaults

Stage CFX in vaults; each action is chain-guarded to BSC.

Open /staking →
  1. Pick a vault, approve CFX if asked, then stage/unstage.
  2. Track positions and receipts in Transactions.

GOOD TO KNOW

  • Switch to BNB Chain (56) before signing — the UI blocks wrong-chain writes.

Referrals & commissions

Share your link; fixed-desk trades with your code record receipt-proven commission.

Open /referral →
  1. Copy your referral link from the Referral page.
  2. Fixed buys/sells that include your address record commission with tx-hash idempotency.

GOOD TO KNOW

  • Commission requires a valid 0x address in the referral field at trade time.

Transactions history

Every swap, fixed trade, convert leg, and commission receipt in one feed.

Open /transactions →
  1. Filter by type (swap / fixed_buy / fixed_sell / convert).
  2. Click any tx hash to verify on BSCScan.

GOOD TO KNOW

  • Convert appears as two linked entries sharing the leg-1 tx reference.

AI assistant

Session-bound AI chat; sessions are wallet-scoped.

Open /ai →
  1. Connect your wallet to start a session.
  2. Ask about trading, NFTs, or the marketplace.

GOOD TO KNOW

  • Sessions are bound to your wallet — reconnecting restores context.

Wallet & network

One rule everywhere: BNB Smart Chain (56), signed by you.

Open /swap →
  1. Install a BSC-compatible wallet and fund a little BNB for gas.
  2. If prompted, approve the switch to chain 56 before trading, buying, staking, or playing.
  3. Never share your seed phrase — support will never ask for it.

GOOD TO KNOW

  • Wrong-chain writes are blocked client-side with a “Switch to BNB Chain” message.
