BreadLinesMarkets

BreadLinesMarkets is an interactive Solana market-structure lens for the FCFS versus MCP debate.

The app is built to make one idea obvious: queueing rules shape markets. Under spam, FCFS starts to look like a bread line. Under MCP, oracle updates land earlier, useful flow gets blocked less often, and market conditions stay more stable.

It started as a simulator, but it is evolving toward real Solana flow analysis: simulated txs, perp execution pain, and wallet transfer activity all framed through the same question: does this flow get breadlined, or does market structure clear it cleanly?

Modes

• Normal Tx Simulator: paste a Solana transaction signature and generate a shareable breadline versus MCP receipt.
• Perps in the Breadline: paste or quick-test a perp route and compare FCFS queue pain against an MCP-style fill path.
• Helius Transfer Intel: paste a wallet address and bring real transfer flow into the market-structure lens through getTransfersByAddress.
• Protocol Comparison: compare FCFS, single-proposer batching, and MCP + FBO with replay priority.

What It Shows

• Wait time
• Txs blocked
• Oracle edge
• Market cost
• Spam pressure
• Perp slippage exposure
• Liquidation-risk pressure
• Funding exposure
• Parsed transfer rows
• Token-2022 fee rows
• Queue-sensitive transfer rows

UX

• Quick Test buttons for normal swaps and perp routes.
• Perps examples for Drift, Jupiter Perps, and Phoenix-style fills.
• Open Sprint popup for community flywheel context without cluttering the simulator.
• Live Solana context via Helius data when enabled.
• Wallet transfer scans powered by Helius getTransfersByAddress, including parsed rows that can surface p-token batch transfer activity when returned by Helius.
• Real-flow framing: transfer history is treated as context for breadline sensitivity, not as a claim that every wallet action is a perp trade.

Tech

• Next.js
• TypeScript
• Recharts
• Framer Motion
• Helius
