Warptoad Cross-Chain Privacy Token Standard
A crosschain private token standard for aztec and EVM rollups.
Warptoad enables fully shielded transfers for both cross and regular transfers
What is Warptoad?
Warptoad is a private cross-chain token standard. It aggregates commitments from multiple chains into a unified "Giga Root" on Ethereum, enabling assets to move between networks without revealing sender, recipient, or origin chain. Integrate it as a composable privacy layer for your dApp, L2, or cross‑chain protocol.
Fully private transfers where everything is private: sender, recipient, which token, amount.
A root that contains all commitments of all chains!
Sending to a warptoad-address will automatically bridge the tokens to the preferred chain while keeping that chainId private!
How it works
Read the source →Warptoad asynchronously creates a merkle tree with all commitments from all chains using the GigaBridge. Proving against this tree allows us to keep the destination chain private.
Warptoad commitments contain the chainId of the destination chain and the recipient is forced to spend/nullify that commitment only on that chain. This allows us to only bridge the commitment tree roots and we can do that asynchronously.
The protocol will automatically disconnect from a warptoad instance, if the contract detects that the rollup code changed.
The security council can prevent this disconnection if the change is deemed secure, but only before the change goes through.
The user can always exit during the exit window.
- Noir circuits and Aztec PXE integration
- Simple private wallet API (WIP)
- Composable adapters for L1/L2s bridge interfaces (WIP)
- Trustless settlement on Ethereum
- No custodial bridge contracts
- Only uses the native rollup bridges
Why it matters
The size of the anonymity set directly affects how private a system is. A unified Giga Root means users on small chains benefit from the same privacy guarantees as those on Ethereum mainnet.
No more worrying about getting front-run on new chains. With Warptoad, no one can see which chain you came from, or where you're bridging your funds to.
Most privacy solutions require a siloed setup or custom logic. Composability allows Warptoad to be added to existing systems.
