Vastlink

Vastlink is an open-source digital asset operating system designed to help people, organizations, and AI manage digital assets across multiple blockchains. Its platform supports keyless wallets powered by multi-party computation (MPC), reducing reliance on a single point of failure while enabling self-custody and enterprise-grade security. Customers can deploy Vastlink on their own infrastructure or use a cloud-based setup, with controls that include multi-factor authentication, spending limits, and multisignature approvals. A developer-focused SDK, APIs, documentation, and live examples support integration into applications and workflows.

Vastlink serves individuals, teams, treasuries, and funds with tools for cross-chain asset management, treasury operations, payouts, and AI-powered earning options. Its services also cover payments, on- and off-ramping, identity and transaction checks including KYC, KYB, and KYT, and compliant cross-border business payments. For real-world asset projects, the platform offers setup and user onboarding, token issuance, and token management. Vastlink uses a pay-as-you-go model, with charges based on consumption rather than fixed subscriptions or upfront fees.
