- [Cactus MPC Wallet](https://thegrid.id/profiles/cactus_custody): Cactus MPC Wallet is a self-custody solution using MPC-TSS technology where private key shares are held collaboratively by the user and Cactus, with no complete key accessible to either party. Key shares are isolated within Intel SGX Trusted Execution Environments, and asset transfers require co-signatures from both parties. The product includes withdrawal whitelists, user permission controls, and AML tooling from the Cactus Custody risk control system. (Wallet, Live)
- [Cactus Oasis](https://thegrid.id/profiles/cactus_custody): Cactus Oasis is an off-exchange settlement solution that holds institutional digital assets in segregated buffer accounts during trading with centralized exchanges, OTC venues, or market makers. Assets remain isolated until trade settlement is confirmed, removing counterparty exposure from insolvency or fund misappropriation at trading venues. The product monitors positions in real time and notifies users when settlement requirements or risk thresholds are not met. (Custodian, Live)
- [Cactus OTC Desk](https://thegrid.id/profiles/cactus_custody): Cactus OTC Desk is an over-the-counter trading service for institutional clients facilitating large-volume cryptocurrency transactions through licensed OTC partners.
