Gemini stated that adoption and transaction volumes continue to grow. Its MPC system can handle near instantaneous withdrawals while maintaining custom policy approval logic for each team.Customers can now transact on several new networks. These include Tron, SUI, MON, Hype, Arbitrum, and XRPL. Gemini added that the service now supports newer signature schemes. As a result, the platform can keep pace with changes across the crypto market.How the MPC Design WorksIn the MPC system used by Gemini Custody, key shares are distributed across several parties. Gemini wrote that the complete private key is never assembled, “not in storage, not during signing.” The company added that “each share alone reveals nothing.”Every transfer is also verified end to end at the signer level. Furthermore, each MPC signer undergoes separate upgrades and operates under independent governance. This process includes cryptographic attestations to the software running in the environment. Gemini said this gives customers the most secure experience possible.The company noted that its current multi-signature setup already protects against any single point of failure. According to Gemini, MPC adds to that protection. The firm also pointed to lower-cost transactions and custody addresses that look like any other. The company stated that this approach modernizes the technology behind its custody service while preserving the custodial relationship.Passkey Approvals and What Stays the SameGemini Custody customers now authorize address-book changes and withdrawals with their own passkey. Gemini said this method is “phishing-resistant because it’s bound to the genuine Gemini site.” A customer may sign in with one passkey and approve transfers with a separate hardware key. Gemini said the approval policy remains under the customer’s control.Existing customers will move to new custody accounts. Each network will have new deposit addresses. Gemini said customers will receive details of the transition in a separate communication. Meanwhile, every net-new Gemini Custody account already opens on MPC infrastructure.Several elements of the service remain unchanged. Assets stay with Gemini Trust Company, LLC, a New York State-chartered trust company and qualified custodian. Client assets remain segregated on-chain in unique, independently verifiable addresses. Account policies such as Multi-User Approval also stay available and configurable. In addition, the company said custody infrastructure must keep up with the market. Gemini described the update as the start of Gemini 2.0.The post Gemini Custody Adopts MPC Technology to Speed Up Crypto Withdrawals appeared first on Blockonomi.
