Payment safety

Your money only moves when it should.

Every payment is checked before it leaves your wallet, and checked again just before it’s sent.

Built to pass every check in an independent 2026 study of payment safety.

Exact price, exact shop
If the amount or who gets paid changes, the payment is refused.
Old requests don't count
Expired payment requests are turned down, every time.
Checked twice
Your balance is checked again right before the money moves.
No half-finished payments
If something fails midway, the payment is cancelled and you aren't charged.

A wallet your agent can use but never own.

Circle-managed smart accounts on Arc, with policy enforced on-chain and off.

01
Keys never touch the agent.
Circle Developer-Controlled Wallets hold the SCA; the entity secret lives in KMS.
02
Policy in two places. Stricter wins.
The off-chain engine is mirrored to an on-chain PolicyManager; disagreement fails closed.
03
Session keys, scoped and expiring.
Caps, allowlists, expiry; revocation fails closed on the next signature.
04
Always ask. Approve above a limit. Autonomous within policy.
Three modes, and a fresh passkey for anything sensitive.

Built on primary infrastructure.

Deterministic finality under a second · USDC is the gas token · no reorgs · the 18↔6 decimal boundary is crossed exactly once.

Testnet (chain 5042002) first.

Every framework, one wallet.

Open by design

No lock-in.

One MCP endpoint, one REST API, TypeScript and Python SDKs, adapters for every major agent framework. Arc first, chain-abstracted from day one.

WEIR doesn't replace your runtime or your model. It gives them a USDC wallet with limits, and gives you the ledger.

Payment graph

Every wallet is a node. Every settled payment is an edge.

Platform

Beyond payments.

A wallet is the first primitive, not the last. WEIR ships the ledger, the analytics and the commerce rails that make an agent's spend auditable.
