Stripe's Link launched Link balance on October 26, 2026, starting with Instinct, a personal AI agent. A user funds a balance held in USDC, sets a maximum spend per purchase, and the agent buys within that limit without asking each time. It is a deliberate shift from the approve-every-checkout model that has defined consumer agent payments so far, and it runs on stablecoin rails.
Highlights#
- More than 350 million consumers already use Link at checkout. Link balance extends that footprint to agents: one funded balance, one per-purchase limit, no per-transaction human sign-off. The agent never sees the user's card details.
- Settlement happens in stablecoins on Tempo, with near-instant, 24/7 finality and sub-cent fees. Tempo says dedicated payment lanes keep agent purchases moving regardless of other network activity, so a presale or a price drop does not wait for an issuer approval or banking hours.
- The limit is per purchase, not a cumulative allowance. Purchases above the threshold still require approval, and the same balance can cover both approved and unattended orders. Users can lower the skip-approval threshold at any time, or set it to zero to require approval on every buy.
- Funding starts from ordinary credit and debit cards, with American Express, Discover and Capital One excluded. Top-ups through the setup link are capped at 150 USD, and onboarding requires SSN identity verification for US users.
- Custody comes in two flavors: custodial balances held by Bridge, the Stripe company, or a non-custodial on-chain wallet via Privy where the user controls exportable keys. Withdrawals go to a bank account or an external crypto wallet after identity verification, with no holding period.
- The rollout covers eligible US regions, with New York listed as coming soon. Other agents can plug in through the open-source Link CLI.
Why it matters#
Unattended agent spending within hard, user-set limits is the exact control problem escrow solves for agent-to-agent deals: caps and settlement guarantees replace per-transaction human approval. Link balance is the consumer-scale proof that budgeted autonomy, not approval friction, is where agent payments are heading.
