Based MediaX

  1. Introduction & Vision

Based MediaX (BMX) is an onchain media exchange designed for the era after “NFT marketplaces.” We focus on:

  • Provable Fairness – every random distribution is powered by Chainlink VRF.
  • Creator‑Aligned Feesall protocol fees are returned to BMX ecosystem token‑holders; no new token emissions.
  • Capital Efficiency – price curves, multi‑currency settlement, and pooled liquidity surface better risk/return profiles for traders.
  • Onchain First – royalties are contract‑level.

If you believe digital ownership should be transparent, fair, and fully onchain, BMX is built for you.

1. Core Concepts

TermMeaning
Onchain MediaThe umbrella term replacing “NFT” — avatars, art, music, video, documents.
Onchain AvatarPFP‑style collectible (e.g., Punks).
PoolSmart‑contract vault with ≥ 2 avatars offered under fixed rules.
Wheel of AvatarsFront-end animation + Chainlink VRF that randomly assigns one or more avatars from a pool to each buyer; the wheel can be spun for multiple avatars in a single transaction.
Price CurveHow pool price evolves: Static, Linear (+Δ), Exponential (×Δ).
Lock Duration1–7‑day period during which sellers’ assets are escrowed.
Vickrey AuctionSealed‑bid; winner pays the second‑highest bid.
English AuctionOpen ascending bids; highest at expiry wins.
  1. Why BMX Instead of OpenSea / Magic Eden?

Marketplace aggregators are great for price discovery, and BMX shows both OpenSea and Magic Eden floors directly in‑app so you can benchmark instantly (look for the twin floor‑price columns on the collection table).

AdvantageOpenSea & MEBased Media X
Automatic on-chain royalty enforcement⚠️ Opt-in “lock-in” escrow; creator must enable ERC-721-C / ERC-1155-C and trading elsewhere is disabled✅ Enforced at contract level, automatic
Provably fair randomised allocations (Chainlink VRF)⚠️ Random-mint style drops supported, but fairness relies on off-chain reveals / dev controls✅ Chainlink VRF guarantees on-chain, verifiable randomness
Buy-side odds analytics⚠️ Basic rarity & floor stats only (no Wheel of Avatars)✅ Full rarity breakdown + remaining supply (via Wheel of Avatars)
Multi-currency settlement pools
Trading-fee accrues to communityLimited100 % of protocol fees → 60 % BMX single-staking · 25 % BLT · 10 % liquidity incentives · 5 % buy-&-burn

Bottom line: You never have to leave BMX—OS/ME floor prices are surfaced alongside our listings, so benchmark instantly and list where fee rebates flow back to you.

  1. veAERO Listings – Why Based Media X Is the Natural Hub

What is veAERO?

veAERO is the NFT that represents a locked AERO position on Aerodrome. Each veAERO NFT carries two parameters that matter to buyers: voting power (how many votes it controls in Aerodrome gauge rounds) and time to unlock (when the underlying AERO can be withdrawn).

Why list on BMX instead of OTC chats or generic NFT markets?

RequirementOTC / Generic NFT siteBMX advantage
Native Base‑chain supportOften missing✅ Built on Base; no bridging friction
Accurate gauge‑vote metadata (votes, unlock date)⚠️ Often missing on generic NFT sites (OpenX does display the data)✅ UI surfaces voting power & remaining lock term directly in the listing card
Multi‑currency settlementLimited✅ Sellers can denominate in wBLT, AERO, wETH, USDC, cbETH, etc.
Fair auctions for high‑VP NFTs✅ Vickrey & English auctions built‑in
Fee rebates to the community✅ 100 % of protocol fees → BMX ecosystem stakers

Liquidity Flywheel

  1. veAERO whales list on BMX for discovery and better execution.
  2. Smaller DAOs & yield seekers buy, gaining instant gauge power without a manual 4‑year lock.
  3. Higher velocity of veAERO trading → more BMX fees → larger rewards pool → more sellers list here.

Goal: Make BMX the central trading hub for veAERO—transparent pricing, instant settlement, and deep liquidity all in one venue.

  1. Seaport Integration — Turbo‑charging Bot Liquidity

Plain‑English TL;DR:

Seaport is an open‑source order‑book that any trading bot can read and fill without touching the BMX front‑end. By speaking the same “language” as most NFT‑sniping and market‑making bots, BMX listings become programmatically tradable. That turns every listing you post into low‑friction inventory for automated traders, which means faster fills and tighter pricing for you.

How Bots Plug In

Bot ActivityHow Seaport Makes It Possible
Real‑time order scrapingBots subscribe to Seaport events and instantly see new BMX listings the moment they hit the chain.
Criteria‑based snipingA bot can issue one standing bid like “any veAERO with ≥ 20 k votes” and Seaport will auto‑match it against qualifying listings.
Atomic arbitrageArbitrageurs can bundle a buy on BMX and a sell on another Seaport‑compatible marketplace in the same transaction, locking in spreads with zero risk.
Liquidity‑provision loopsMarket‑makers rotate inventory: buy under‑priced avatars on BMX, relist at target margins, or vice‑versa—all via contracts, no UI required.

Why This Helps You as a Lister

  • Deeper Bid‑Side Liquidity – Bots running 24/7 vacuum up mis‑priced or trending items that human buyers might miss, giving you faster exits.
  • Tighter Spreads – Continuous arbitrage keeps BMX prices in line with global markets, so fair value is discovered quickly.
  • Higher Fill Probability for Auctions – Algorithmic bidders can monitor Vickrey & English auctions and step in with size near expiry, protecting you from lowball outcomes.
  • Zero Extra Work – You list once on BMX; Seaport broadcasts the order. Bots (or any other venue) can fill it without additional gas or approvals from you.

Bottom line: Seaport turns BMX into bot‑friendly territory. More automated takers → more reliable sales and better realised prices for every seller on the platform.

  1. Creating Listings
    1. Single Listing

Sell a specific avatar at a fixed price in the ERC‑20 of your choice or in ETH.

  1. Random Pool (Wheel of Avatars)
  2. Deposit two or more avatars.
  3. Set Sell Price – starting price per purchase.
  4. Choose Price Curve & Δ – Static / Linear / Exponential.
  5. Pick Lock Duration – 1–7 days.
  6. Select Currency – any whitelisted ERC‑20 (wETH, USDC, cbBTC, wBLT, etc.).
  7. Sign & List – assets are locked; buyers can now spin the wheel.
  8. Auctions
    • Vickrey – Sealed bids; winner pays second‑highest (truthful‑bidding incentive).
    • English – Open ascending bids; highest at expiry wins.

Flow on BMX

  1. Seller picks Vickrey or English, reserve price, and duration (1–7 days).

  2. Buyers lock bids (Vickrey) or place visible offers (English).

  3. On expiry:

    Vickrey: contract reveals bids, calculates winner’s payment = second‑highest bid, and refunds differences.

    English: highest bid auto‑settles.

  4. Net proceeds (after protocol fee) route straight to the seller’s wallet.

  5. Auction Mechanics – Vickrey vs. EnglishPowered by an exclusive licensing agreement with Sealed (opens in a new tab), bringing fully on-chain Vickrey auctions to Base. | Feature | Vickrey Auction | English Auction | | --- | --- | --- | | Bid Visibility | Private. All bids are encrypted on‑chain until the auction closes. | Public. Every bid is visible in real time. | | How to Bid | Submit one sealed bid ≥ reserve price.Gas is refundable if you’re out‑bid. | Place incremental bids, each higher than the current best offer. | | Winner Determination | Highest bidder wins, but pays the amount of the second‑highest bid – incentivises honest, value‑based bids. | Highest bidder at the moment the timer expires wins and pays their own bid. | | Strategic Edge | • No “sniping” risk – last‑second bids don’t beat you cheaply.• Ideal for rare grails where users may otherwise under‑state value. | • Transparent price discovery – good when true market value is unknown.• Encourages competitive bidding wars that can exceed expectations. | | When to Use | You have a 1/1 or ultra‑rare avatar and want to avoid low‑ball games. | You’re unsure of demand and prefer an open contest to maximise price. |

Price Curves – Static | Linear | Exponential

Curve TypeFormula (after each sale n)Example – Starting Price 0.05 ETHWhen to Use
StaticPn = P00.05 ETH → 0.05 ETH → 0.05 ETH …You just want to clear inventory quickly at a fixed price.
LinearPn = P0 + (n × Δ)Δ = 0.01 ETH0.05 → 0.06 → 0.07 → 0.08 …Gradually rewards early buyers while still capturing upside as pool inventory thins.
ExponentialPn = P0 × (1 + Δ)^nΔ = 10 % (0.10)0.05 → 0.055 → 0.0605 → 0.0666 …Scarcity premium ramps fast – great for rare‑heavy pools you expect to empty quickly.

Key Take‑aways

  • Static keeps entry simple; best for high‑supply, low‑variance pools.
  • Linear lets you pre‑define profit per sale – transparent and predictable.
  • Exponential compounds scarcity; small Δ creates steep climbs after a few buys, deterring late entries unless the remaining rare value justifies the jump.

Practical tip: back‑test your curve against collection floors. A pool that starts at 1.1 × floor with a 20 % exponential Δ becomes 2.11 × floor after just four purchases—brilliant if rares remain, toxic if they’re already gone.


  1. Buying from a Pool
  2. Open a Random pool from Active Listings.
  3. Analyse odds — price‑to‑floor ratio, rarity mix, remaining supply, time left.
  4. Click Buy (choose quantity). Wheel spins while Chainlink VRF finalises.
  5. Your avatar is revealed and lands in your wallet instantly.

Tip — Hunting Rares: If the only rare in a pool remains after multiple buys, the probability of pulling it increases with each remaining purchase.

  1. Rewards

Each Sunday at 00:00 UTC the epoch flips (when rewards campaigns are active).

  • Leaderboard – Top‑10 buyers and sellers share the fee‑rebate pool. Buyers and sellers split sales 50/50.
  • Claim Delay – Rewards become claimable 24 h after epoch end to discourage wash trading.

No extra steps: trade and you’re in.

  1. Fees

  1. Security & Fairness
  • Chainlink VRF – Verifiable proof for every random outcome.
  • Automatic on-chain royalty enforcement – Creator payouts are enforced at the contract level and cannot be bypassed on the BMX platform.
  • Non‑custodial – Assets reside in audited smart contracts; BMX never holds your keys.

  1. FAQ

Is the Wheel of Avatars gambling?

No. Every purchase yields an avatar; randomness only decides which one.

Can sellers withdraw mid‑pool?

No. Assets are locked until the selected duration expires.

Why would I pay above floor?

You’re paying for a chance at rarer avatars whose market value exceeds the current pool price.

Does BMX have its own token?

Yes—BMX governs certain protocol upgrades and can be staked to receive accrued fees from protocol operations, but there are no emissions.
