Interchain Connectivity Companies

Orbit Chain is a cross-chain blockchain project built around its Orbit Bridge, which enables asset and data transfers across multiple heterogeneous blockchain networks. The protocol operates its own chain with a governance token (ORC) that holders use for on-chain voting, staking, and delegation to shape protocol decisions. Orbit Bridge supports connections to networks including XRP and a range of EVM and non-EVM chains, with a validator set drawn from partner organizations.

Rainbow Bridge is a cross-chain bridge protocol enabling token transfers between Ethereum, NEAR Protocol, and Aurora (an EVM-compatible layer built on NEAR). Users connect wallets such as MetaMask, Rabby, Brave, or Coinbase Wallet to initiate transfers, with the app providing a transfer history scanner and address-routing options. The protocol is closely associated with Aurora, NEAR's EVM environment, and serves retail users moving assets across these three networks. The site includes explicit security warnings about wallet compatibility with the Aurora network, reflecting a focus on user-safety transparency.

Sig.Network is a cross-chain messaging and execution layer that enables smart contracts deployed on one blockchain to execute native transactions on other blockchains without bridging or wrapping assets. The core architecture uses a decentralized MPC validator set to produce threshold signatures, converting cross-contract calls into standard signed transactions that are submitted directly to destination chain mempools, supporting Ethereum, Solana, Polkadot, and Bitcoin. The primary users are DeFi application developers who want to access liquidity and assets across ecosystems from a single deployment, without migrating contracts or adopting new tooling. Sig.Network launched its Ethereum mainnet in March 2025 and Solana mainnet in August 2025, with Polkadot and Bitcoin integrations on the roadmap.

Stargate Finance is a cross-chain liquidity bridge protocol that facilitates asset transfers across multiple blockchain networks within a single transaction. The protocol supports transfers of assets including USDC, USDT, ETH, and BTC. It is built on LayerZero's messaging infrastructure and employs a unified liquidity pool model to address liquidity fragmentation issues present in traditional bridge architectures. The protocol offers both standard and advanced transfer modes and includes staking functionality for its native STG token. Users can execute cross-chain asset movements without token wrapping or multiple sequential bridge operations.
