Squid Router

Squid Router is a cross-chain liquidity and routing protocol that enables users and developers to swap any token across more than 100 blockchains in a single transaction. Founded in February 2022 and launched on mainnet in January 2023, Squid has processed over $6 billion in volume across more than 4 million transactions for more than one million unique users, and its infrastructure powers cross-chain functionality in over 1,000 applications.

What Squid Does

Squid's core product is a routing engine that finds the optimal path for moving value between chains, aggregating liquidity from 130+ DEXs and, through its CORAL layer, from offchain market makers as well. A user who wants to move assets from one chain to another submits a single transaction; Squid handles the routing, intermediate swaps, and cross-chain settlement without requiring the user to sign additional transactions or hold wrapped intermediate assets.

The protocol's developer surface includes a drop-in widget for rapid integration, a REST API suitable for any programming language, and a JavaScript/TypeScript SDK. All integrators must obtain an Integrator ID before accessing the production API. Squid's own consumer-facing bridge at squidrouter.com is powered by the same infrastructure it exposes to third parties.

Protocol Architecture and Evolution

Squid launched as an Axelar-native protocol. In its first version, every cross-chain swap was coordinated through Axelar's General Message Passing (GMP) layer, with axlUSDC serving as the hub asset connecting source and destination chains. Smart contracts deployed on each supported chain acted on behalf of users — executing swaps, deposits, and other on-chain actions — while Axelar's validator set provided the underlying security. The protocol's design minimized attack surface by ensuring contracts never held special permissions or locked tokens.

Squid 2.0, released during 2024, replaced this single-protocol architecture with a graph-based routing engine that aggregates multiple bridge and messaging protocols simultaneously. Alongside Axelar, the system now routes through Circle's Cross-Chain Transfer Protocol (CCTP), the Cosmos IBC protocol, Chainflip, and LayerZero, selecting the most efficient path for each transaction. Quote response times fell to approximately 500 milliseconds with the 2.0 engine.

In December 2024, Squid introduced CORAL — the Cross-Chain Order Routing and Auction Layer. CORAL adds a request-for-quote (RFQ) mechanism on top of the existing AMM routing. Market makers receive user RFQs and fill orders immediately on the destination chain; they are subsequently reimbursed through the slower on-chain settlement layer. This separation of execution from settlement reduces end-user gas costs by up to 90% on supported routes, eliminates MEV exposure, and enables near-instant transaction finality. CORAL's architecture also allows for batching multiple user intents destined for the same asset on the same chain, reducing gas costs further for all participants. The current Squid Intents layer runs on Trusted Execution Environment (TEE) infrastructure, and Axelar functions as one of several execution layers rather than the sole settlement backbone.

Chain and Token Coverage

Squid supports over 100 blockchains spanning multiple ecosystems: EVM chains including Ethereum, Arbitrum, Base, Avalanche, Polygon, and BNB Smart Chain; Cosmos chains via IBC, including Osmosis, Injective, Celestia, and more than a dozen others; Bitcoin via Chainflip integration; Solana; Hedera; XRPL; and emerging L2s and appchains. The protocol routes between more than 20,000 tokens across 130+ integrated DEXs.

The Chainflip integration, added during 2024, was a technical milestone that enabled multi-protocol hopping. A single transaction can now traverse IBC, then Axelar, then Chainflip in sequence to connect ecosystems that previously had no common interoperability path — for example, moving assets from a Cosmos chain to Bitcoin natively without wrapping.

Pre- and post-hooks in Squid's API allow developers to attach arbitrary smart contract calls to any swap. A user can swap a source token, bridge to a destination chain, and deposit into a yield protocol as a single signed transaction, without holding intermediate assets or signing additional approvals.

Integrations and Use Cases

Squid's infrastructure is embedded in MetaMask, Brave, Keplr, Ledger Live, and Opera's MiniPay mobile wallet, among more than 1,000 third-party integrations. The protocol supports enterprise use cases through bespoke implementations: Circle integrated Squid for cross-chain FX flows involving its USDC and RLUSD stablecoins, while MiniPay uses Squid for tokenized asset access on the Celo network. A Tempo adapter enables autonomous cross-chain payment flows for machine-to-machine settlement. An MCP (Model Context Protocol) adapter released in 2025 allows AI agents to execute cross-chain swaps through natural language commands, extending Squid's routing capabilities into agentic workflows.

Squid also exposes a Squid Wallet View product that lets users see their cross-chain portfolio across all supported chains and wallets from a single interface.

Funding and Security

Squid raised a $3.5 million seed round in January 2023, led by North Island Ventures with participation from Distributed Global, Fabric Ventures, Chapter One, and angels including Stani Kulechov and Zaki Manian. A $4 million strategic round followed in January 2024, led by Polychain Capital with participation from Nomad Capital, Maelstrom, Chorus One, Binary Builders, and others. The protocol has completed nine external security audits, including reviews from Ackee Blockchain and Consensys Diligence, and reports 99.99% uptime since mainnet launch.

In May 2026, a separate third-party module named SquidRouterModule was exploited for approximately $3.2 million across Gnosis Safe wallets due to a verification flaw in its contract code. Squid stated publicly that this module has no official affiliation with its contract suite and that none of its own users were affected. Squid's own router contracts were not involved in the exploit.

$QUID Token

Squid launched its $QUID governance token in mid-2026. The token has a fixed supply of one billion with no further minting possible. A public sale ran from June 30 to July 3, 2026, offering 50 million tokens — 5% of total supply — at $0.045 per token, implying a $45 million fully diluted valuation. The sale was conducted through Legion for non-US/UK participants and Kraken for US/UK participants. Public sale tokens unlocked 100% at the token generation event with no vesting, while investor and team allocations carry a twelve-month cliff with no tokens released at TGE. Circulating supply at the TGE was approximately 143 million tokens.
