About
Breeja is a cross-chain stablecoin settlement network built for both humans and autonomous agents. It lets a payer send USDC or another stablecoin across chains without needing gas tokens on the destination network, and without forcing the recipient to manually manage the transfer flow. The flow is simple: the payer signs an EIP-3009 transfer authorization, a relayer submits the deposit on the source chain and pays gas, and a router selects the best route based on live conditions like gas cost, destination liquidity, and user preference. The funds then arrive at the recipient on the destination chain as a single, seamless payment rather than a fragmented bridge experience. The platform is designed around one shared settlement layer for multiple front doors. A human can use the web app, while an agent or developer can integrate through the SDK, MCP tooling, or an x402-compatible flow. The SDK is the core product, with the browser app serving as just one client interface. Under the hood, Breeja treats each supported chain as both a source and a destination, using a relayer to provide liquidity and a routing engine to balance fast settlement against trust-minimized alternatives. It supports two main settlement modes: a fast custodial route backed by relayer-controlled liquidity, and a more trust-minimized CCTP-based route for users who want lower custodial risk. Breeja is therefore not just a token bridge; it is a programmable cross-chain payment layer for real-world settlement, with gas abstraction, route optimization, and agent-friendly integration built in. This makes Breeja especially well suited to ETHGlobal-style demos: it combines consumer UX, agent tooling, developer APIs, and blockchain infrastructure in one coherent product. The value proposition is that payments can be initiated from a natural-language prompt, a browser wallet, or an SDK call, while the underlying settlement remains deterministic, reusable, and consistent across client surfaces.
How it's made
Breeja is a cross-chain stablecoin settlement network for humans and autonomous agents. It lets a payer send USDC across chains without holding gas on the destination network, using signed transfer authorizations and a relayer that submits the payment and pays gas. A routing layer selects the best path based on gas price, liquidity, and user preferences, with either a fast custodial route or a more trust-minimized CCTP route. Breeja is built as a unified system: Solidity smart contracts for settlement, a TypeScript relayer for execution and liquidity coordination, a Next.js frontend for human UX, and an SDK that exposes the same payment flow to agents, MCP tools, and x402-style integrations. Partner technologies like CCTP, The Graph, Privy, ENS, and Ledger improve trust, identity, and infrastructure. The key design choice is that the AI layer interprets intent and explains the route, but does not authorize settlement or control the trust boundary.
