Settlement at agent speed, on the universal identity & security layer for autonomous agents. The on-ramp to OST — the native WiKey token that powers agent payments and the X402 economy, where the agent requests a signature and never holds the key. 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 requests a signature and never holds the key, while the compliance engine checks every transfer. OST powers agent identity, agent transactions, X402 micropayments, and access to the WiKey security stack.
Pick your path — the experience is tailored for each.
Buy OST with your credit card or swap from stablecoins — in a few clicks, no seed phrases.
