List of Bridge projects on Bitcoin (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.

Mt Pelerin Exchange is an on/off-ramp service for buying, selling, and swapping cryptocurrencies using bank transfers or card payments, delivered directly to a user's own wallet. It supports transactions up to certain limits without requiring identity verification and settles in a range of fiat currencies. A built-in cross-chain bridge lets users transfer supported assets between multiple blockchains with guaranteed delivery, and an embeddable version of the same exchange functionality can be integrated into third-party websites and apps through direct links, an embedded frame, or a mobile package. The service also lets users pay everyday invoices and bills, including rent, insurance, taxes, and utilities, directly with cryptocurrency, with automatic conversion and settlement to the recipient. It operates as a non-custodial intermediary that never holds user funds itself.

PowPeg facilitates two-way asset transfers between Bitcoin and Rootstock networks through specialized hardware security modules and multi-signature protocols. The system uses merge-mining consensus and tamper-proof PowHSM devices to secure Bitcoin deposits without human intervention.

Rootstock Token Bridge enables ERC-20 token transfers between Ethereum and Rootstock networks through federation-secured smart contracts. The system locks original tokens and mints equivalent Side Tokens maintaining 1:1 ratios with support for various stablecoins and ERC-20 assets.

Relay Bridge is a cross-chain bridging and swapping product that moves assets between blockchains through relayer-based intent settlement. Users submit a transfer request and receive a quote, after which a relayer fills the transaction on the destination chain before funds are released on the origin chain, enabling fills in a few seconds. It supports same-chain and cross-chain swaps across a wide range of blockchains and is used by wallets and applications seeking fast, low-cost transfers.

BOB Mainnet is a hybrid rollup that combines Bitcoin security guarantees with Ethereum Virtual Machine compatibility. It settles transaction proofs while checkpointing state to Bitcoin and inherits additional security from a Bitcoin-secured fraud-proof bridge design, allowing native Bitcoin to be used directly in smart contracts without a wrapped intermediary. Developers deploy standard EVM smart contracts on the network, and users access decentralized applications, staking, and lending services built on top of it through a dedicated web application.

bridge.eco provides DeFi swaps across multiple blockchains while channeling all protocol fees into regeneration and enables direct retirement of verified eco-credits on multiple chains.

B2 Bridge is a cross-chain bridge that transfers the native token and other assets between the primary network and additional connected blockchains. Users lock assets on the source chain and receive equivalent tokens on the destination chain through the bridge's smart contracts. It enables asset movement between the network and other supported chains for use across decentralized applications.

BTC Bridge is a Bitcoin-focused bridge that moves Bitcoin and related assets from the Bitcoin mainnet into the network's ecosystem. Users connect a Bitcoin wallet and deposit funds, which are confirmed on Bitcoin before being credited on the destination network. The bridge is the primary entry point for bringing native Bitcoin liquidity into applications built on the network.

Hemi Tunnel is a bridge protocol enabling secure transfer of Bitcoin and Bitcoin-native assets between the Bitcoin network, Ethereum, and Hemi. Assets are locked in custodianship vaults and representative tokens are minted on Hemi after six Bitcoin confirmations, with withdrawals verified against the rollup state root submitted to Ethereum. The protocol uses hVM to monitor UTXO tables and custodianship vault activity, with misbehaving custodians subject to slashing to prevent unauthorized transfers.

interBTC is a trustless Bitcoin bridge that lets users lock native BTC with decentralized vault operators and mint iBTC at a 1:1 ratio on the Interlay Polkadot parachain. Vault operators deposit overcollateralized assets such as DOT or USDT as insurance, with collateral slashed to reimburse depositors in the event of vault failure. iBTC is redeemable for native BTC on the Bitcoin blockchain at any time without reliance on a central intermediary.

Kintsugi is the experimental Bitcoin bridge and DeFi network running as a Kusama parachain, serving as the canary deployment for Interlay's interBTC protocol. Users lock native BTC with overcollateralized vault operators to mint kBTC, a 1:1 Bitcoin-backed token redeemable for native BTC at any time. The network also includes an integrated AMM, borrowing, and lending interface accessible at kintsugi.interlay.io, governed by KINT token holders.

Utexo Bridge is a cross-chain bridge for atomic swaps between Bitcoin (RGB and Lightning) and other blockchains such as Ethereum, enabling private transfers with instant settlement on Bitcoin.

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.

TeleSwap Bridge is a decentralized bridge protocol that moves Bitcoin and Bitcoin-based tokens to and from multiple EVM-compatible chains and TON. It uses light-client verification to validate Bitcoin transactions on-chain, removing reliance on oracles or centralized validators, while custodial nodes post collateral that is slashed if they act dishonestly. Users can bridge assets, swap Bitcoin assets directly against other tokens through an integrated automated market maker, and stake the protocol's utility token to earn a share of network fees.

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

Omnity Hub implements fully on-chain Bitcoin interoperability through trust-minimized verification, enabling cross-chain asset transfers and contract interactions. The system connects Bitcoin with multiple blockchains while maintaining security through on-chain verification.

Clementine implements BitVM-based two-way peg architecture between Bitcoin and Citrea, facilitating trust-minimized BTC transfers through zero-knowledge proof verification. The system enables capital-efficient operator mechanisms and single-round fraud proofs for Bitcoin settlement.

Secure bridge facilitating asset transfers between Bitcoin and Yona networks, enhancing Bitcoin's programmability.
