Challenges faced by Slingshot

Slingshot Finance required a non-custodial key management solution that could ensure a decentralized experience where users were the only party to control access to user accounts. Slingshot was specifically interested in a design that leverages TSS MPC cryptography, because TSS MPC provides a secure design that is truly non-custodial.

‍

Slingshot Finance also required an API-based solution for key management. Slingshot Finance’s focus is high frequency on-chain trading, so they desired a high degree of control over the user experience.

Solution offered by Portal

Slingshot chose Portal for:

• API-based integration: Portal was the only solution on the market to offer TSS MPC API-based wallets-as-a-service. With APIs, Slingshot has greater control over the trading experience because the wallet service is implemented on the backend.
• TSS MPC Cryptography: Portal's transparent 2 of 2 TSS MPC architectural design ensures that the key management is truly non-custodial, such that Slingshot is not a custody of user's funds and users themselves control access to the wallet.
• ‍Fast signing speeds: Signing speeds measured in seconds allows Slingshot to facilitate high frequency on-chain trading for its users without compromising the experience
