Builder Banter — Episode ~19/20: X402 Builders, Roadmaps, and Open Q&A

Opening, Format, and Disclaimers

• Host: Notorious (Pai / Pay AI; official comms referenced as “Kai Network”), ran the session and introduced recurring builders. Early audio hiccups (mute/echo) resolved quickly.
• Format: ~5 minutes per builder; quick intro, recent progress, what’s next; end-of-session Q&A using Stage X (anonymous questions). Host attempted Stage X wallet sign-in; Quicksync support noted.
• Core disclaimer (repeated twice): This is an open builder space. Nothing is financial advice or an endorsement. Some projects have rugged post-appearance; do your own research. Only trust official Pai token migration info from the official account and site.
• Pai/Pay AI update: Building payments for AI; deep synergy with X402. Token migration happening in ~24 hours via migrate.fund. Migrate ASAP to avoid a 5% penalty. Beware of scammers/fake accounts; only trust official handle and migrate.fund.

Tapestry AI (Kimbo, co-founder; Bobo, co-founder)

• Mission/problem: The IP landscape (copyrights, patents, etc.) is fragmented, with archaic APIs and inconsistent metadata. Tapestry aims to be the “Oracle of IP,” aggregating and standardizing IP metadata for creators, enterprises, and developers.
• Product components:
  • Willy: An AI agent with multimodal search to assess IP status. Users can upload a media asset and Willy will:
    • Flag potential copyright infringement and whether an asset is in the public domain.
    • Provide availability timing for assets nearing public domain.
    • Suggest legally-usable, similar IP alternatives (AI-driven recommendations).
• Launch/status: POC launched last week; onboarding waitlist cohorts daily. Access via tapestry.ai (login -> magic link -> waitlist; cohorts lifted regularly).
• Host suggestion: Highlight Tapestry capabilities with an “IP of the day” meme/token launcher (cross-chain possible). Team explored this at a prior hackathon; feasible, but not current focus.
• Roadmap highlights:
  • ERC‑8004: Upgrading Willy into an on-chain public-domain intelligence agent with provable, verifiable outputs. Two core capabilities:
    • Automated metadata aggregation (crawl/standardize archives).
    • Public-domain status verification with legal logic, anchoring results on-chain.
  • X402 integration: Handle paid requests (e.g., bulk datasets, detailed reasoning trails) common in B2B workflows; customer-tailored datasets monetized via X402.
• Notes: “Steamboat Willie” inspiration underlines the public-domain ethos; provenance on-chain can mitigate PVP/fake-origin problems for IP-themed launches.

Relay AI (Alex, 19, team lead voice on call)

• Vision: A platform/marketplace for developers to list APIs and earn per-call via X402, eliminating Stripe/PayPal overheads and infra complexity.
• Progress:
  • Closed beta open; 4 partners onboarded; selective admissions for quality. Early adopters get priority marketplace placement and incentives.
  • SDK progressing; pitch deck complete for partners/investors; forthcoming explainer video.
  • Treasury: Two $1,000 buybacks executed (measured; reiterated they’re a utility project, not a memecoin).
  • Upcoming article across business media explaining “list API, set price, get paid per usage” thesis.
• Q&A:
  • “What if I’m not a dev?” Early focus is developer market, but businesses will benefit as ecosystem matures.
  • “Will you increase liquidity?” No current plans; at current market/cap, liquidity is not the main concern.

Osgoliath (Lord of the Rings nod; Oregon-based)

• Vision: Open swarm autonomous AI systems plus privacy-first communications for storage/data centers.
• Product path:
  • 16TB open-source storage system (Raspberry Pi-based) with a fully open codebase for community replication.
  • Autonomous drone swarm layer to privately transmit crypto “over the air” using multiple privacy layers (ZKPs plus additional encryption), akin to Monero’s multi-layer privacy approach; integrate X402 for payments.
• Timeline: Storage testing roll-out targeted before Thanksgiving.
• Q&A:
  • Open-source? Yes, fully open for community audit of firmware/AI.
  • Host suggestion: Explore Radar.io for X402 privacy; ZK is the right direction.

Chroma Fund (Main developer)

• What: Web3 crypto-trading games on Solana — instant, fair, low-fee, and transparent.
• Problem vs solution:
  • Web2 gaming platforms: 5–10% fees, 24–48h withdrawals, opaque systems.
  • Chroma: ~2.5% fees, instant payouts, full transparency with VRF + real-time price oracles.
• Token: Chroma token is full platform utility (required to play; earnable; staking; IP benefits).
• Infra: Uses Pai to abstract gas complexity; praised Pai docs for easy integration.

Quicksync / Stage X (Waseem, founder)

• Quicksync: Building user-owned collaborative digital spaces (encrypted chat, file sharing, guest access, etc.).
• Stage X: A flagship built atop Quicksync infra — a live event platform powering this session’s Q&A.
  • Key features: Anonymous, structured Q&A (up/downvotes; Reddit-style), emojis and replies, live token buying within the space, no wallet/account required for listeners, minimal host friction.
  • Monetization (upcoming): Tips/donations, super-questions/super-votes, “book a host,” host share of live volume, fundraising curves — turning live streams into monetizable assets.
  • Results: 5–10x engagement over typical spaces; hub launched for creator profiles; video/screen-sharing on roadmap.
• Q&A: “How do hosts make money?” Via tips/donations, a share of in-session volume, paid super-interactions, fundraising, and bookings. Vision: creators stream on existing tokens and earn creator fees without minting new tokens.

Visor (Lil Fat Frank aka “Karen” handle; Solana dev at Oro Gold)

• Product: A browser extension that explains Solana transactions in plain English and analyzes a wallet’s last ~100 transactions.
  • Extension generates a secure local wallet (password-protected), holds user USDC for pay-per-call via X402, and only operates on Solscan transaction/wallet pages for safety.
  • Outputs include wallet activity timing, top interacted programs/addresses, total fees paid, and plain-English per-transaction summaries.
• Status: Open-source repo shared; built initial version months ago; wrapped with X402 during a mini-hackathon; submitted to the X402 hackathon.
• Roadmap: More analytics (token/dev histories), better UX (history/bookmarks), cleaner UI, multi-chain support.
• Host note: Client-side tooling is critical for seamless X402 adoption; great to see buyer-side UX advancing.

Dexfry / DexFro.xyz (Lego, CMO)

• What: An X402-powered AI/data layer for Solana — decentralized data/payment infrastructure for agentic apps and the next generation of on-chain intelligence.
• Core offerings:
  • Data Intelligence: >400 APIs (token analytics, smart money, risk, market, social, wallets), turning raw Solana data into machine-ready intelligence.
  • X402 Marketplace: A decentralized marketplace where anyone can list an API and instantly convert it to a pay-per-call X402 service (pricing, metering, micropayments handled).
  • Proxy Layer: Converts standard APIs into X402 endpoints so providers don’t need to learn X402 internals.
  • AI Arena: A competitive arena where LLMs (e.g., GPT variants) trade real capital on Solana DEXs using Dexfry’s data APIs; winners determined by PnL.
• Roadmap: Deliver live APIs + marketplace; AI Arena Season 1 in this quarter; Go-based proxy development ongoing.
• Q&A: “What if an agent runs out of funds?” Expect retry/reload handling; they aim to manage such cases gracefully.

work.fun (Static, founder)

• What: Micro-job/task marketplace — create tasks with rewards; others complete and claim. Goal: make Web3 work/collab easy and safe; agents included in the work economy.
• X402 progress:
  • Custom X402 server live; launched a helper agent to guide job creation.
  • Initially supported Solana USDT; now added Base USDC (bridge volume benefits back to Solana). All endpoints now support Base.
  • Anti-abuse: API keys for advanced job creation (moderation/spam prevention). Public, permissionless endpoints exist for simple jobs to maximize agent discoverability.
  • Listed endpoints on x402scan; host encouraged everyone to explore x402scan to understand agent/server interactions.
• Roadmap: More public endpoints and job types; Telegram bot for community jobs; potential collab with MemePewter.

MemePewter

• What: No/low-code agent builder that lets anyone create agents with personality, knowledge (document uploads), and skills/commands (from prompt templates to complex webhooks).
• Major X402 feature: One-click deployment of agents as public X402 pay-per-use APIs with auto-registration on x402scan — solves discoverability for creators.
• Vision: Composability — chaining multiple micro-agents/endpoints into higher-level workflows (compose-layer). Hackathon demo “Market Pewter” used a chain of agents (trend fetch → image gen → caption → post) to complete a marketing job on budget.

X402 Labs

• What: “Stripe for blockchain access” focused on RPC aggregation for autonomous agents.
  • Single endpoint fans out to multiple RPC providers (e.g., Helius/QuickNode/Triton; partners expanding). No vendor or facilitator lock-in. Pay-per-call via X402.
  • SDK in testing; integrating with chat UIs like Mallory for agent benchmarking vs. traditional subs; batch operations (discounted volume), WebSocket/live streaming on roadmap.
  • Token: Launching a utility/governance token to align early adopters/supporters and fund provider-side scaling (buybacks noted). Host re-stated the global no-financial-advice disclaimer.

Quantu (Cube)

• What: Mobile app to create agents by voice; building X402 discoverability and trust tools on Solana.
• Syntax discovery tool: Embedding-based search across X402 endpoints (query and description embeddings), surfacing relevant services.
• Reputation gap on Solana: Unlike EVM/ERC‑8004, Solana lacks standardized agent identity and reputation. Plan:
  • Port ERC‑8004 agent identity/verification concepts to Solana.
  • Wrap X402 endpoints into agents-as-entities; enable rating of entities (not just endpoints), mirroring how users rate entities in search ecosystems.
• Timeline: A first version of the ERC‑8004-equivalent for Solana targeted next week; open-source, audits planned; cross-chain (Ethereum/Base/Solana) agent tooling planned.

OpenKit X403 (Sam)

• What: X403 — HTTP-native authentication for Solana to standardize wallet-auth for web apps and agents. Concept tagline: “X402 moves the money; X403 moves the gates.”
• How: Client/server SDKs (TypeScript, Python), with LangChain support in-progress. Provides a common pattern for servers to verify the connected wallet and return a 200 when identity is verified (beyond a vanilla ‘connect wallet’ UX). Early adopters using it to token-gate bots/groups.

Misha

• Contributions: RFCs to improve Solana X402:
  • Payment timeout control: Today, buyer transactions effectively time out at ~80–90 seconds (blockhash expiry). Proposal introduces a deadline validator program + durable nonces to allow longer/explicit timeouts.
  • Smart wallet support: Current Solana X402 path is EOA-only; proposes support for smart wallets (e.g., Squads-style) without escrow workarounds to unlock broader adoption.
  • SATI (Solana Agent Trust Infrastructure): A Solana-native standard akin to ERC‑8004, enabling agent identity and cross-chain identity verification (e.g., verify Ethereum identity from Solana). Goal: unify standards in a fragmented Solana ecosystem.
• Ask: Community feedback on RFCs (linked via Coinbase X402 repo); open collaboration with Quantu and broader builders. Host pledged support and offered to connect parties.

Stage X Q&A Highlights (selected)

• To Relay AI: “What if I’m not a dev?” — Businesses can benefit; today’s focus is devs. Liquidity increase? — No immediate plans; not a priority at current market/cap.
• To Tapestry: Similar-IP suggestions? — AI-based; continuously training Willy, learning from customer behavior; strong focus on public-domain alternatives.
• To Quicksync/Stage X: “How do hosts earn?” — Tips/donations, a share of live volume, fundraising, super-questions/votes, booking hosts. Vision: stream on existing tokens and earn creator fees without minting new ones.
• To Dexfry: “What if an agent runs out of funds?” — Retry/reload; aiming for robust handling.
• To Osgoliath: Open-source auditability? — Yes; fully open for community review; multi-layer privacy stack in progress.

Notable Themes and Gaps

• X402 maturity: Rapid progress on server-side/merchant infra; client/buyer UX (e.g., Visor) remains crucial for seamless adoption.
• Identity and trust: Strong momentum to bring ERC‑8004-like agent identity and verifiable outputs/reputation to Solana (Quantu, Misha) to curb pricing spoofing and improve discovery.
• Privacy: Multi-layer privacy for agent payments and communications (Osgoliath; Radar.io tip; ZKPs) is a continuing need.
• Composability: Builders envision chaining micro-agents/endpoints into complex workflows (MemePewter, x402scan compose layer, host interest in discoverability UX).
• Creator economy: Stage X is pioneering monetizable, action-driven live spaces (buy-in-space, super-interactions, creator fees on live volume), aiming to avoid fragmented “creator token” models.
