Relic Protocol

The first provably secure source of historical data on-chain

Relic Protocol enables dApps to access all of Ethereum’s historical data with maximal security and minimal gas costs.

About

Relic

Relic allows attestations to be generated about historic blockchain states, producing digital relics for the user to show off or present to other DeFi applications.

For more information about how relics are created and how you can use them, see our docs.

Certificates

Stand the test
of time

Birth
Certificate

Birth certificates are Relics, provable soul-bound tokens, that record the age of an Ethereum account. Show off how long you have been using Ethereum, or use them in your smart contract to provide benefits to long-standing community members.

Claim

Attendance

Attendance certificates are Artifacts, attested soul-bound tokens, that record your participation in real world and virtual events. Build your personal on-chain reputation, or provide on-chain benefits to active community members.

Build

Let’s make history

Historical
State Oracle

Provably and securely access any historical Ethereum state, including accounts, blocks, events, storage and transactions. Build unique dApps using data that is now available on-chain for the first time.

Off-chain
Attestations

Access attestations of off-chain data. We partner with event organizers to provide certificates of attendance, and will soon offer reputation attestations to assist with security and on-chain compliance.

Cryptographic
Security

Built by a team of Web3 security experts and open source for anyone to review. Historical state attestations are proven using zk-SNARKs, while off-chain attestations are cryptographically signed by Relic.

Use Case:
Airdrop

Reduce the complexity of airdrops by using Relic to verify eligibility on-chain. For example, establish an account's age or possession of tokens at any point in time. All completely transparent and provable.

Use Case:
Engagement

Provide benefits to active members of the Ethereum community, such as promotions and early access to new features. Reduce risk by limiting access from new accounts without an established history.
