NFT EXECUTION LAYER

x671.space

The open execution layer for NFT trading. Built for creators, traders, and the next billion AI agents.

Pre-seed · $450K SAFE · February 2026

Problem

Blockchains have been designed to be open and permissionless, but the current NFT market operates on closed order books.

The result:

❖
Fragmented liquidity and worse prices for traders.
❖
An innovation bottleneck where a duopoly controls most order flow.
❖
Developers and AI agents still lack a neutral, open access layer.
❖
New marketplaces face a cold-start problem due to locked liquidity.

Solution

A Seaport compatible Open Order Book (OOB) with three access layers.

SDKfor Builders & Marketplaces

API / CLIfor AI agents

OPEN ORDER BOOK (OOB)

Seaport (Onchain Settlement)

The result:

❖
Users gets wider distribution at zero additional cost: Existing Seaport orders from OpenSea and Blur can be copied into the open order book, gasless.
❖
A shared liquidity layer for Builders and Marketplaces: Orders are cryptographically secured and portable across all interfaces.
❖
Programmatic NFT trading: Native access for Autonomous AI agents.

Why Now · Market inflection

Industry shift from platform lock-in to open execution + distribution.

AI agents already execute the majority of onchain transactions and are growing exponentially.

First AI-to-AI NFT trade already happened in [month/year].

~500M crypto users today → 1B+ by 2030.

No open shared liquidity layer has become the default rail for programmatic NFT trading. AI/bot trading needs API-first access.

Why this wins

  • Shared liquidity instead of isolated order books
  • API-native access for AI agents and bots
  • SDK and CLI make integrations faster for builders
  • Reference UI proves the infrastructure end to end
  • Protocol-level positioning creates leverage across every integration

Market

NFTs are not dead, but liquidity is locked.

NFT trading volume: ~$5.6B/year (2025)

OpenSea and Blur control ~95%+. Magic Eden sunsetting EVM and Bitcoin, Tensor 2-3%. Everyone else practically dead or disappeared.

Business Model & Revenue Path

  • 1. Open Order Book Fee (0.5%)

    Charged on every trade executed through the Open Order Book — whether filled via UI, external marketplace using SDK, or AI agent using API. Revenue scales with every integration.

  • 2. Token Swap Fees (0.3% via 0x)

    Users can swap any ERC-20 token directly within our marketplace. AI bots and human traders instantly rebalance portfolios without leaving x671. (OpenSea's swap volume exceeds NFT volume by 2-3x).

  • 3. API Subscriptions (Free / $9 / $42 / Custom)

    Tiered MRR from developers and AI operators. Paid tiers provide higher rate limits, dedicated websockets, and deep historical indexing to scale trading strategies.

"I've been deep in NFTs since 2021. I founded projects, traded, built communities — and watched every marketplace make the same mistake: locking liquidity behind their walls. When I couldn't find open infrastructure to build on, I decided to build it myself. This isn't a pivot or an experiment. This is the thing I've been working toward for four years."

Let’s unlock open liquidity for every creator, trader, and AI agent.
