説明

Tabline lets a user open a "tab" — a wallet-granted spending permission (ERC-7715/7710) capped per period —

instead of signing an unlimited token approval. Merchants get a billing layer on top: plans (fixed subscriptions

or metered pay-per-use), verified on-chain settlement, idempotent retries, and subscriber-initiated cancel.

Tabline never custodies funds; every charge is a direct wallet-to-merchant transfer the contract verifies after

the fact.

Built for recurring SaaS-style billing and pay-per-call AI agent spend, both of which are awkward to do safely

on-chain today: deposits lock up capital, and unlimited approvals are a standing security risk.

ハッカソンの進行状況

- Tabline.sol: plan registry + settlement ledger (Foundry), 29/29 tests passing including fuzz - Keeper: billing engine + HTTP API (Node/TS) handling scheduling, retries, webhooks — 38/38 tests passing against a real local chain - @tabline/sdk: wallet-integrated client (connect, subscribe, cancel, on-chain plan creation) — 17/17 tests - Reference app (Next.js): Shop (checkout), My Tabs (subscriber view), Merchant dashboard, Agent (pay-per-call demo) — builds clean, 7/7 smoke tests passing - Deployed to Arbitrum Sepolia testnet - Still open: a live wallet-permission run end-to-end on testnet, and a real pilot subscriber/merchant
