Settlement, treasury and cross-chain at agent speed — on WiKey, the trust boundary for AI agents. The Bridge takes the human off the hot signing path: the agent asks, the boundary decides, and it never holds the key. The on-ramp to OST — the native WiKey token that powers agent payments and the X402 economy. Buy or swap with stablecoins, or pay with a credit card.
The WiKey Marketplace & Bridge lets users and AI agents acquire OST, the native WiKey token, in the way that fits them best. Swap stablecoins (USDC, USDT, DAI) for OST, bridge from any supported chain, or simply pay with a credit / debit card and receive OST directly through your WiKey identity — the agent asks and the boundary decides, so the human is off the hot signing path and the agent never holds the key, while the policy gateway vets every transfer. It's the same settlement and treasury layer replacing Safe (Gnosis) multi-sig and Anchorage custody in our live pilots. OST powers agent identity, agent transactions, X402 micropayments, and access to the WiKey security stack.
