List of Bridge projects on Starknet (2026)

Starkgate is the canonical bridge between Ethereum and Starknet. It locks assets on the source chain and mints equivalents on the destination chain, with LayerZero integration for cross-chain messaging on select routes. Users move assets in either direction using a single canonical contract rather than relying on third-party bridges.

Nostra Bridge facilitates asset transfers between Starknet and external blockchain networks. The protocol ensures secure cross-chain transactions through verified bridge contracts.

Warp Routes is a modular cross-chain asset bridge built on the Hyperlane messaging protocol, using lock-and-mint and collateral mechanisms to move tokens between blockchains. It lets developers permissionlessly deploy routes that support fungible and non-fungible tokens as well as native gas assets, with each route configurable for its own security model. Users interact with deployed routes through a bridging interface to transfer assets across a wide range of connected blockchain environments.

Orbiter Finance is a cross-rollup bridge for transferring assets across Layer 2 networks. It helps users move funds efficiently while reducing costs and reliance on intermediaries.

rhino.fi Bridge transfers tokens between multiple blockchains using Layer 2 technology. Users move digital assets across 30+ blockchains with standard transaction times of under 60 seconds.

Owlto Bridge is a cross-chain bridge that transfers assets such as ETH and stablecoins across multiple blockchain networks. It uses an intent-centric Maker and User model combined with AI-driven route optimization and zero-knowledge proof verification, allowing Makers to fulfill transfers on destination chains without centralized custody. The system evaluates gas prices, liquidity depth, and route availability to complete most transfers within seconds. Users also earn points for completed transfers, daily check-ins, and referrals, which serve as a loyalty and incentive mechanism tied to bridge usage.

Onramp Money is a fiat-to-crypto payment infrastructure that lets individuals and businesses convert between local currencies and cryptocurrencies. It processes fiat purchases and sales of digital assets through local payment methods, and also lets users swap between supported tokens across multiple blockchains, spend crypto through gift cards at a range of merchants, and move value through stablecoin-based payouts. The service is accessible through a website widget, mobile applications, and an API or SDK that other wallets and exchanges embed for their own users. Identity verification and compliance checks are built into the transaction flow across the countries it serves.

Garden Bridge provides intents-based cross-chain Bitcoin swaps through solver networks, enabling transfers between Bitcoin and multiple blockchain ecosystems including Ethereum, Arbitrum, Base, Solana, Berachain, and Starknet.

strkbtc.io is a bridge that moves native BTC into Starknet, minting strkBTC backed one-to-one by Bitcoin locked on the Bitcoin network. Built by StarkWare and powered by Atomiq, it lets Bitcoin holders bring BTC onto Starknet to access DeFi and optional privacy. The bridge runs a federated model operated by the strkBTC Federation, with a roadmap toward a trust-minimized architecture.

ChainRails is a merchant payment gateway that lets businesses accept cryptocurrency and fiat payments from any supported blockchain, token, or currency through a single integration. It processes transactions with an intent-based architecture that escrows funds on-chain, automatically routes and swaps or bridges them, and settles to the recipient's preferred chain, token, or bank account. Businesses integrate through an embeddable payment modal, direct API and SDK calls, or contract-level integration, and can generate shareable payment links, manage deposits and withdrawals, and sponsor network fees for end users through a paymaster feature. A dashboard provides visibility into volume, revenue, and API configuration. Fiat conversion and identity verification are handled through integrated ramp and KYC flows.

tBTC is a decentralized Bitcoin bridge that enables native BTC holders to mint a 1:1 backed ERC-20 token across multiple blockchains without a central custodian. The protocol uses threshold cryptography with a rotating 51-of-100 node operator model to secure deposited Bitcoin, distributing control so no single entity can act unilaterally on user funds. Users can mint tBTC directly across multiple chains

Train Protocol uses PreHTLC atomic swaps through intent-solver architecture, enabling trustless cross-chain asset transfers. The system includes a bridging interface, solver agent software for liquidity providers, and coordination infrastructure that operates through local verification and cryptographic protocols without requiring third-party intermediaries.

Clober DEX is a decentralized exchange running a fully on-chain central limit order book for spot and derivative trading. It uses the LOBSTER matching algorithm with a book manager and segmented segment tree data structures to process limit and market orders at low gas cost, and issues order positions as NFTs. The app also aggregates quotes from external swap routers, offers liquidity vaults where users provide capital to market-making strategies, and includes a bridging interface for moving assets between supported chains. Perpetual futures trading is available alongside spot markets, and the platform runs an points-based rewards program tied to trading and liquidity activity.
