About
Picasso, built by the Composable Foundation, extends the Cosmos IBC protocol to chains outside Cosmos, becoming the first to connect Ethereum to Cosmos via IBC and later extending to Solana and Polkadot/Kusama. It provides trust-minimized cross-chain transfer of assets and data, including stablecoins, with security stronger than conventional bridges.

Across Protocol
Intent-based optimistic cross-chain bridge
Across is an intents-based bridge where users deposit on the origin chain and relayers fill on the destination in seconds, settling via UMA's optimistic oracle. It co-authored the ERC-7683 cross-chain intents standard and offers fast, low-cost stablecoin bridging across major L2s.

Avalanche ICM / Teleporter
Native cross-L1 messaging for Avalanche
Interchain Messaging (ICM) and its Teleporter contracts are Avalanche's native cross-chain messaging layer built on Avalanche Warp Messaging. The TeleporterMessenger contract lets dApps and assets, including stablecoins, move and invoke functions across Avalanche L1s with relayer incentives, replay protection and a standard developer interface.

Axelar
Universal interoperability network
Axelar is a proof-of-stake interoperability network with a permissionless validator set and slashing, providing General Message Passing (GMP) and cross-chain token transfers across 70+ chains. It connects Cosmos and EVM ecosystems and underpins aggregators like Squid Router.
Bungee
Consumer bridge aggregator by Socket
Bungee is the consumer-facing cross-chain bridge aggregator built by Socket that finds the cheapest and fastest route across many bridges and DEXs in one click. It is a popular front-end for stablecoin and token transfers across EVM chains.
Cata Labs
Cross-chain liquidity protocol (Catalyst)
Cata Labs was a New York-based team building Catalyst, an open-source permissionless cross-chain liquidity protocol for modular blockchains that used a 'unit of liquidity' abstraction to enable atomic swaps of native assets across rollups and app-chains. The Catalyst AMM wound down and Cata Labs was acquired by LI.FI in February 2025.
cBridge / Multichain alternatives — Allbridge
Cross-chain stablecoin transfer protocol
Allbridge is a cross-chain bridge focused on stablecoin transfers between EVM and non-EVM chains (including Solana, Tron, Stellar, and Sui), offering Allbridge Core stable pools and Allbridge Classic wrapped-asset bridging.
