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

Allbridge Core is a cross-chain bridge for transferring dollar-pegged stablecoins between blockchains. It connects independent liquidity pools on each supported chain through a virtual stablecoin reference asset, using stable-swap mathematics to execute transfers without wrapping tokens. Smart contracts on every chain hold the liquidity and enforce the pooling mechanism non-custodially, so funds are never controlled by a central operator. Selected routes can alternatively use native burn-and-mint or omnichain token standards, liquidity providers earn a share of transfer fees, and a software development kit lets other protocols embed the same cross-chain transfer functionality directly.

Allbridge Next is a cross-chain bridge that moves stablecoins and native gas tokens across a set of supported blockchains with low, predictable fees and fast settlement. It automatically routes each transfer over whichever underlying mechanism settles fastest for the asset pair, including omnichain token standards, native burn-and-mint flows, or intent-based execution, removing the need for users to manage liquidity pools directly. The bridge also allows users to top up native gas on the destination chain in the same transaction as a token transfer. A privacy-preserving transfer option using zero-knowledge proofs is in development.

Allbridge Classic is a cross-chain bridge that transfers both native and wrapped tokens between EVM and non-EVM blockchains. It supports mint-and-burn transfers for large amounts alongside native token transfers, and a dynamic fee system lets stakers of the platform token reduce their transfer fees. The bridge covers a wider set of blockchains and tokens than the company's newer bridge products. This product is deprecated and scheduled to be discontinued in favor of the company's newer bridge offerings.

Transfers settle atomically via a Verifier Smart Contract on NEAR Protocol, with automatic refunds on failure. An SDK is available for developer integration of cross-chain stablecoin transfers.

MoonPay Trade is a decentralized exchange aggregation and routing service that finds pricing for token swaps across multiple blockchain networks. It combines aggregation of external liquidity sources with a first-party router to execute trades, supporting gasless transactions, stablecoin routing through custom decentralized exchanges, and a multicollateral bridge for cross-chain transfers. Wallets, exchanges, and applications integrate its APIs or smart contracts directly to offer users swaps, cross-chain transfers, and conversion of tokens back to fiat, including access to prediction market positions from any source token.

Pheasant Bridge is an intent-centric cross-chain bridge protocol that transfers ETH and USDC between Ethereum and EVM-compatible Layer 2 networks using an optimistic mechanism. Users submit bridge requests on the source chain; a relayer fulfills the request on the destination chain while a disputer monitors for fraudulent transactions. AI-powered intent logic selects cross-chain routes based on current network conditions. USDC transfers are also available via Circle's Cross-Chain Transfer Protocol (CCTP). Developers can embed bridging functionality into applications through the Bridge-as-a-Service (BaaS) offering, which includes an SDK and an embeddable widget.

deBridge DLN is a cross-chain liquidity network implementing intent-based architecture for asset transfers between blockchain networks. Users specify desired cross-chain outcomes through intents, which professional market makers fulfill competitively by providing tokens on destination chains immediately and claiming source tokens afterward. The system operates on a zero-TVL model without traditional liquidity pools, enabling transfers to settle within 1-2 seconds with guaranteed rates and tight spreads across supported networks.

CryptoRoute is a self-custodial swap engine that lets users exchange crypto assets across blockchain networks without creating an account. Users pick a source and destination asset and network, receive a live quote with fees and a minimum receivable amount, and send funds to a one-time deposit address after address validation. The swap itself routes wallet-to-wallet through an intent-based settlement layer, with a live status page tracking progress until the destination asset arrives. It supports a wide range of assets and networks, including major blockchains and stablecoins, without CryptoRoute ever holding user funds or keys.

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.

Mayan is an intent-based cross-chain swap and bridge protocol that moves tokens between blockchains without wrapped assets. It routes transfers through several underlying methods, including an auction-driven model where drivers compete to fulfill orders using liquidity already on the destination chain, a USDC-based path leveraging a third-party cross-chain transfer protocol, and a message-based bridging path, automatically selecting the optimal route by asset, size, and destination chain. This lets users and integrators swap assets across EVM and non-EVM ecosystems in as little as one second with guaranteed output amounts. Mayan supports transfers across a wide range of blockchains and integrates with numerous wallets and third-party platforms as a routing layer.

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.

Across Bridge is a crosschain interoperability protocol that moves tokens and executes swaps between blockchain networks. It operates through an intent-based architecture in which user requests are fulfilled by a competitive network of relayers who front capital, with an optimistic verification system settling and repaying relayers afterward. The protocol delivers fills in about two seconds on supported chains and combines bridging with embedded crosschain actions, allowing a swap, transfer, and destination-chain contract call to be composed into a single transaction. It also uses a modular settlement layer that lets other exchanges and applications route intent-based orders through the same relayer network for crosschain execution.

ChainPort is a cross-chain bridge enabling token transfers across multiple blockchain networks through wrapped asset bridging, native token bridging, external cross-chain protocol integrations, hybrid bridging for wrapped blue-chip tokens, and stablecoin bridging. The protocol stores up to 98% of assets in multi-signature cold storage via Fireblocks MPC encryption and Gnosis Safe, maintaining a small hot contract balance for active bridging. Users pay a fee per port in the ported token, PORTX, or the chain's native gas token.

ChainPort Private Bridge is a managed bridge service for token issuers providing shared vault custody through a 3-of-5 multi-signature structure, splitting control between ChainPort's team, the token issuer, and an optional third-party trustee. Token issuers can customize bridging fees, configure address whitelisting and blacklisting, restrict porting directions, set per-transaction and per-address transfer limits, and enable automated 24/7 emergency freeze monitoring for their bridge integration.

Hyperbridge Protocol is a cross-chain interoperability protocol that verifies consensus and state proofs from connected blockchains for secure message passing. It aggregates cross-chain messages into cryptographic proofs that any connected chain can verify, and provides messaging primitives that let applications send verified instructions and read remote chain state directly. The protocol operates as a coprocessor on Polkadot, with permissionless relayers submitting proofs and light-client contracts validating them on destination chains. It also underpins per-token bridging contracts that burn, mint, or wrap assets across chains with the same proof-based verification.
