Summary

Core Advantages

Zero Slippage

Direct burn-and-mint transfers with exact output amounts; no pooled liquidity or wrapped assets.

Single Transaction UX

Users sign once with relayer quote data embedded; Cashmere relayers complete destination minting.

MEV Resilience

Guaranteed outputs remove sandwich and frontrunning vectors.

Programmable Fees

Real-time quotes exposed via API, signed, and verified on-chain for predictable fee management.

​
Transfer Flow

1

Quote

Client requests a signature from the Gas API. Response includes fee, deadline, and signature (ECDSA or Ed25519).
2

Burn

User calls the Cashmere contract on the source chain, burning native stablecoins and emitting an event.
3

Attest

Relayer retrieves the issuer attestation, verifies signatures, and prepares destination calldata.
4

Mint

Relayer submits the mint transaction on the destination chain; recipient receives the exact amount minus relayer fee (if paid in USDC).
