Is it safe?

Safer than handing your AI a credit card, less forgiving than one — and both halves matter. The protections: the allowance you set is enforced by the wallet itself, not by the AI's good judgment, so your AI structurally cannot spend more than you allowed. Every payment has to be signed by your wallet and only your wallet — payments can't be forged or copied by someone watching. And the default state is that nothing moves: an ignored payment request just expires. The less-forgiving half: these payments are final, like cash. There's no bank to call and no dispute line. The system compensates by being careful before money moves instead of forgiving after — small limits, and escrow arrangements where the money automatically comes back to you if what you paid for isn't delivered. Our own habit is publishing the security audits, because trust should come from specifics rather than promises. Start with small amounts while you learn the feel; that advice would be identical for any new payment method.
