Spark Assets
Create and transact with custom privacy-preserving tokens on the Firo blockchain — stablecoins, utility tokens, and even privacy-preserving NFTs.
What Are Spark Assets?
Spark Assets extend Firo's Lelantus Spark protocol to allow anyone to create custom tokens that inherit the same strong privacy properties as FIRO itself. This means:
Hidden Asset Types
Observers cannot tell which type of asset is being transferred in a transaction — it could be FIRO, a stablecoin, or any custom token.
Hidden Amounts
Just like Spark transactions, the amount transferred is cryptographically hidden from anyone except the sender and receiver.
Shared Anonymity Set
All Spark Assets share a single anonymity pool with FIRO, meaning every transaction strengthens privacy for all assets.
Privacy-Preserving NFTs
The protocol can support non-fungible tokens with privacy features — ownership and transfers can be hidden from the public.
Use Cases
Private Stablecoins
Issue stablecoins pegged to USD or other currencies with full transaction privacy. Businesses and individuals can transact without exposing their financial activity.
Tokenized Real-World Assets
Represent ownership of real-world assets (real estate, commodities) on-chain with privacy. Investors can hold and trade without public exposure.
Community & DAO Tokens
Create governance or utility tokens for DAOs with private voting and holdings. Members can participate without revealing their stake.
Confidential Fundraising
Run token sales or crowdfunding where contribution amounts and participant identities remain private.
How It Differs From Other Platforms
Most token platforms (Ethereum ERC-20, Solana SPL) create tokens with fully transparent transactions — anyone can see who sent what to whom. Even "privacy tokens" on these platforms typically only hide the identity, not the amounts or asset types.
Spark Assets are fundamentally different because they're built on top of a privacy-first protocol. The asset type itself is hidden, meaning an observer can't even tell whether a transaction involves FIRO or a custom token.
Key advantage: Because all Spark Assets share the same anonymity pool as FIRO, creating a new token doesn't fragment privacy — it increases it for everyone.
Development Status
Spark Assets are on Firo's mid-term roadmap. The protocol design is complete and implementation is underway. Follow the roadmap for the latest updates.
