SEABW 2026 Vibe Coding Hackathon submission — ICONSIAM Bangkok, May 20–21 2026. Solo build by @ss251, pair-programmed with Claude Opus 4.7.
A public Telegram bot. Any Thai service provider — tuk-tuk driver, market vendor, tour guide, freelancer — texts the bot in Thai. In ~10 seconds they become a Solana mainnet AI agent registered on agent-registry-8004 with an x402-payable HTTP endpoint listed on Pay.sh. Foreign AI assistants (Claude Code, Codex, Gemini) discover the agent, pay in real Tether USDT on Solana mainnet over x402, and receive a booking. The merchant gets a Telegram push notification and a one-tap Bitkub off-ramp.
One Thai message → one foreign AI assistant → real USDT settles in 400ms → THB lands in a Thai bank. No app installs. No middlemen.
Note on the messaging layer: the original plan was LINE (40M Thai users, SCBX-aligned distribution). LINE Official Account creation now requires Thai-issued SMS verification, which a foreign solo builder can't satisfy from inside a 19h hackathon window. The bot package is intentionally generic — Telegram is the live demo channel; the LINE adapter is ~30 lines of code (telegram.ts ↔ line.ts is the only file that differs) and the entire downstream stack is identical. Distribution target remains the Thai LINE user base; SCBX gets the same on-chain data layer regardless of input channel.
| Sponsor | Real integration |
|---|---|
| Solana Foundation | agent-registry-8004 mainnet program (Quantu Labs, ERC-8004 on Solana) + Pay.sh marketplace publish |
| AWS | Lambda (every endpoint) + Kiro (AI-co-authored commits) + Bedrock Claude 4.7 once model access approves; Anthropic API as the active fallback path |
| SCBX / SCB 10X | Typhoon API (api.opentyphoon.ai/v1) for native Thai LLM intent parsing |
| Tether | USDT-SPL mainnet mint Es9vMFr… — every x402 settlement is real Tether |
| Bitkub | Public ticker API + real on-chain SPL transfer to merchant's Solana-USDT deposit address |
| Hashed / ShardLab | Direct alignment with the 2026 Protocol Economy thesis (stablecoins as rails + autonomous AI agents + on-chain credit) |
