Umbra and Streamflow launch confidential token vesting on Solana
Umbra and Streamflow have introduced a confidential token vesting solution on the Solana blockchain. This integration allows projects to distribute tokens to stealth addresses, ensuring recipient identities remain private during the vesting process. The solution aims to address privacy concerns associated with traditional public vesting schedules, particularly for team allocations, advisor grants, and investor distributions.
- ▪The integration combines Streamflow’s vesting infrastructure with Umbra’s stealth address framework.
- ▪Tokens are distributed to Umbra-generated stealth addresses, keeping recipient identities disconnected from on-chain transactions.
- ▪This solution allows for private recipients while maintaining the auditability of the vesting schedule.
