Guides to how downbad works under the hood — the contracts, the fees, the mechanics of buying and selling on Algorand.
- The composable marketplace V2
Why we rebuilt the contract that holds every listing, what changed for creators, sellers, and buyers, and how cross-marketplace listings work.
- Royalties for creators
Step-by-step guide to setting your default royalty rate, deciding whether sellers can override it, and how earnings reach you.
- Offers
What an offer wallet is, why deposits exist, the difference between collection / trait / asset offers, and how accepted NFTs reach you.
- P2P NFT-collateralized lending
Borrow ALGO against your NFTs, or lend ALGO against a whole collection. How loans, interest, and collateral work, and how offers stay safe from fake mints.
- Deals
Trustless peer-to-peer trades — swap NFTs, tokens, and ALGO directly with another wallet. How the escrow works, how to spot fake assets, and what happens on-chain.
- Token swaps & fees
How the swap widget routes through the Haystack DEX aggregator, what the 1% fee covers, and why there is no extra markup on top of the displayed quote.
- Featured placements
How the homepage carousel is filled, how bidding for a slot works as a daily lottery rather than an auction, when you are charged, and how to verify the draw was fair.
- Shuffles
Run a randomized NFT drop: how to set one up from Creator Tools, how phases, eligibility, and fees work, and why real art in the pool can be peeked without a placeholder.
- Banner Studio
Publish background-free art so holders can build banners, wallpapers and profile pictures from your NFTs. The manifest format, hosting and CORS requirements, and how holder-gated overlays work.
