Strengths and weaknesses
Pros	Dual compatibility with EVM and CosmWasm smart contracts Audited by Hacken in March 2026 Native 24/7 liquidity orchestration for Latin American fiat stablecoins Self-custodial FX routing without intermediary counterparty custody	Typical transaction fees average approximately $0.002 per transfer Settlement finality completes in roughly 1.8 seconds Full EVM execution environment supports standard Solidity tooling and libraries Processed over 8 billion transactions across more than $3.0 trillion in cumulative volume
Cons	Suffered an upstream Cosmos EVM exploit draining 148 million KII in August 2026 Required an emergency validator halt that paused block production at block 9,355,723 Cross-chain transactions rely on external bridge infrastructure such as Hyperlane	Relies on sidechain checkpoints rather than native Layer 2 zero-knowledge rollups Bridge smart contracts on Ethereum introduce third-party settlement and locking risks Past smart contract vulnerability resulted in the loss of 801,601 tokens in 2021 Separate Polygon zkEVM sequencer suffered an operational halt in July 2026
Best for	Emerging market remittance platforms, Institutional cross-border payment processors, EVM and Cosmos cross-chain developers	High-frequency stablecoin payment providers, Fintech developers seeking EVM compatibility, DeFi apps requiring sub-cent fees
