Open a tab, not an approval. Recurring and pay-per-use payments on Arbitrum, built on scoped, revocable wallet permissions instead of unlimited token approvals.
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.
