Starknet Bridge is the gateway connecting Ethereum, Bitcoin, Solana, and more to Starknet — a high-performance Layer 2 network powered by advanced STARK cryptography.
Starknet Bridge was built with a single goal in mind: to make it effortless for anyone to move digital assets onto Starknet. Whether you're a developer exploring the ecosystem, a DeFi user chasing low fees, or a newcomer taking your first step into Layer 2 — Starknet Bridge provides a secure, intuitive, and trustless path to Starknet.
Developed by StarkWare Industries, the team behind Starknet itself, Starknet Bridge is more than just a bridge — it is the canonical infrastructure that connects Starknet to the broader blockchain universe.
We believe that decentralized finance should be fast, affordable, and secure. By leveraging STARK proof technology, Starknet Bridge delivers all three without compromise.
Starknet Bridge combines multiple bridge protocols into a unified, elegant interface. Every feature is engineered to give you the best possible bridging experience.
Built on STARK cryptography with withdrawal limits and multi-party audits protecting every transaction.
Transfer assets to Starknet in approximately 5 minutes, with Solana and OFT token bridges completing in under 2 minutes.
Bridge from Ethereum, Solana, and over 150 chains via integrated Hyperlane, LayerZero, and CCTP protocols.
A clean, unified UI brings all bridge types together — no switching between platforms or navigating complex flows.
Your keys, your assets. Starknet Bridge never takes custody of your funds — all transfers are fully trustless and on-chain.
Monitor every transaction in the Activity tab with live updates, explorer links, and actionable status indicators.
Starknet Bridge integrates four distinct bridge technologies, each optimized for different use cases and asset types. Together they form the most comprehensive gateway to Starknet available today.
The official Ethereum ↔ Starknet bridge for ETH and ERC-20 tokens. Built on STARK proofs and operated by StarkWare, it is the most secure and battle-tested path to Starknet. Supports permissionless token enrollment via the StarkGate Registry contract.
Enables cross-chain bridging between Starknet and 150+ networks including Solana, Arbitrum, Base, Optimism, and Polygon. Hyperlane's modular security model allows each chain to customize its trust assumptions while maintaining fast, permissionless transfers.
Supports Omnichain Fungible Token (OFT) standard assets like WBTC and SolvBTC. LayerZero handles minting and burning across chains to maintain a unified token supply, offering high speed and strong security for supported assets.
Circle's Cross-Chain Transfer Protocol enables native USDC bridging by burning on the source chain and minting on the destination. Supports both Standard Transfers and Fast Transfers via CCTP V2, bringing native USDC liquidity directly to Starknet.
Every architectural decision in Starknet Bridge prioritizes user safety. Withdrawal limits, formal audits, STARK cryptographic proofs, and a public bug bounty program through Immunefi ensure that security is never an afterthought.
All Starknet Bridge bridge contracts are open source and verifiable on-chain. Anyone can inspect the code, audit the logic, and interact with the contracts directly — no permission required.
Developers can enroll new ERC-20 tokens directly through the StarkGate Registry contract without requiring approval. This permissionless design reflects our commitment to open, censorship-resistant infrastructure.
From automatic withdrawal options to real-time activity tracking and clear fee breakdowns, every feature in Starknet Bridge is designed to reduce friction and give users confidence in every transfer they make.
By making it easy to bridge into Starknet, Starknet Bridge plays a foundational role in growing the Starknet ecosystem — bringing liquidity, developers, and users to one of the most powerful Layer 2 networks in existence.
Starknet Bridge is developed and maintained by StarkWare Industries — the pioneering team behind STARK proof technology and the Starknet Layer 2 network. Founded by world-class cryptographers and engineers, StarkWare has been at the forefront of blockchain scalability since 2018.
StarkWare's mission is to bring the benefits of ZK-proofs to the entire blockchain ecosystem. Starknet Bridge is central to that mission — serving as the primary on-ramp for users and liquidity into the Starknet ecosystem.
With offices across the globe and a distributed team of passionate engineers, StarkWare continues to push the boundaries of what's possible on Ethereum and beyond.
