What bridge does Squid use?
Squid uses a multi-protocol approach to cross-chain routing, selecting the best available bridge or messaging layer for each transaction. This ensures broad chain and token coverage without dependency on any single interoperability protocol.
Circle Cross-Chain Transfer Protocol (CCTP)
Circle's CCTP facilitates USDC transfers securely between blockchains networks via native burning and minting. CCTP is operational between the Noble blockchain and other CCTP-compatible networks such as Avalanche, Arbitrum, Ethereum, and Optimism. Consequently, users can move USDC across both EVM-compatible and Cosmos chains without any slippage.
Inter-Blockchain Communication (IBC)
Within the Cosmos ecosystem, Squid leverages existing liquidity (for example, from platforms like Osmosis) to perform token swaps. Additionally, Squid uses the Packet-Forward Middleware for optimizing asset routing over the IBC protocol. This strategy minimizes issues related to liquidity fragmentation, enhancing the efficiency of swaps not only between EVM and Cosmos chains but also across various Cosmos networks.

Chainflip
Chainflip connects different blockchains, like Bitcoin, Ethereum, and Solana, enabling direct asset swaps with minimal slippage through its unique Just-In-Time (JIT) Automated Market Maker (AMM) design. Squid leverages Chainflip for native swaps to, from, and across Bitcoin and Solana.
Axelar
Squid uses Axelar's general message passing for connections where other protocols don't apply, providing additional coverage across EVM and Cosmos chains.
