LI.FI, Across and deBridge Lead Multi-Chain Stablecoin Routing

In 2026 LI.FI, Across and deBridge route billions of dollars a day across more than 30 blockchains. Market participants move stablecoin liquidity across Ethereum, Arbitrum, Base, Optimism, Solana, Polygon, BNB Chain and other networks. Global stablecoin supply is on track to reach about $420 billion by year-end 2026.

Cross-chain aggregators evaluate multiple bridge and DEX routes for each transfer and combine them into multi-step executions. Aggregated routing compares liquidity and fees across options rather than sending funds through a single bridge with fixed fees and pools. Aggregator routes deliver materially lower effective cost on many transfers, often reducing execution cost by a range cited by market participants of roughly 30% to 70% compared with using one bridge alone. Aggregators also expose APIs that enable programmatic routing for protocols, custodians and payment services.

LI.FI provides bridge and DEX aggregation across more than 30 chains and offers REST APIs and SDKs for developers. It can construct routes that bridge and swap in a single execution. Jumper Exchange is a consumer interface that uses LI.FI’s routing engine; the routing logic is the same across both products. Because LI.FI supports wide coverage and multiple integrations, its routing contracts and integrations increase the overall smart contract surface exposed in a transfer.

Across focuses on transfers between Ethereum mainnet and major layer-2 networks. It uses a relayer model that fronts liquidity to recipients and is reimbursed after canonical verification, shortening settlement times on optimistic rollup corridors. ETH and major L2 transfers through Across typically settle in under two minutes. Across relies on UMA’s optimistic oracle for verification and charges a low relayer fee that varies with network conditions.

deBridge routes native liquidity between EVM chains and Solana using a decentralized validator network instead of wrapped-token pools. That design avoids the slippage that can occur when destination pools are thin. deBridge settlements on supported routes commonly complete in under two minutes. Its security model includes slashing conditions for validator misbehavior. Chain coverage prioritizes depth and speed on supported corridors rather than the widest possible coverage.

Other protocols serve specific requirements. Stargate uses LayerZero and unified liquidity pools to move native assets across supported EVM chains at a transparent 0.06% fee. Socket returns detailed route metadata for integrators that want to implement custom routing logic. Squid, built on Axelar’s General Message Passing, enables single-transaction cross-chain swaps that execute arbitrary logic on the destination chain.

Security considerations include the layered smart contract exposure introduced by the routing layer above underlying bridges. Vulnerabilities in an aggregator contract can affect multiple routes. Industry practices cited by developers include independent audits for routing contracts, configurable slippage limits, and fallback mechanisms for failed routes. Integrating a single aggregator reduces engineering work but concentrates counterparty and contract exposure, which parties assess alongside audit histories and fee and speed requirements when choosing a routing service.
