Projects

In addition to working with our amazing clients, ScopeLift regularly builds publics goods, open source projects. These projects provide an opportunity to experiment with new tooling and processes, then bring those learnings back to our clients. It's also simply an opportunity for us to build cool stuff we see as missing in the ecosystem!

Privacy Preserving Payments for the EVM

Umbra is an open source protocol for stealth payments on EVM blockchain networks. It enables privacy preserving transactions where the receiver's identity is only known to the sender and receiver.

Think of it like this: before anyone sent you funds, you sent them a brand new, never before used address. Only the sender would know you control that address. Payments via Umbra work similarly, but are non-interactive - the sender can generate an address they know only you will be able to access.

Stealth Address Standards

ERCs Authored

ScopeLift is working with developers and researchers across the ecosystem to advance two ERCs that standardize stealth addresses on the EVM, making privacy accessible to all.

Together, ERC-5564 and ERC-6538 create a lightweight, flexible and powerful set of tools for developers to adopt stealth addresses. The ERCs are designed to be interoperable and completely permissionless - a true public good.

Use Cases

An extension to OpenZeppelin Governor — now part of the OpenZeppelin governance standard library — that enables novel voting schemes. Delegates can split their voting weight across For/Against/Abstain options for a given proposal.

This building block unlocks new use cases: voting with tokens while earning yield in DeFi, voting with tokens bridged to L2, shielded privacy preserving voting, and crosschain voting powered by Wormhole.

Used by: Compound, ZKSync, Wormhole, Gitcoin, PoolTogether, Frax, Obol, Rarible, AGLD
