Strengths and weaknesses
Pros	Average execution speed of one second across supported networks No wrapped tokens used, settling directly in native destination assets Average transaction fee sits below $0.01 plus network gas Connects over 85 networks without pooled treasury lock-in	Connects non-EVM chains like Bitcoin, Solana, and TON directly with EVM networks Requires no account creation or KYC identity verification to bridge Processed more than $10B in cumulative volume across 50+ supported blockchains Smart routing compares multiple external liquidity sources to minimize slippage
Cons	Verification hub depends on an authorized oracle signer architecture Solver capacity limits maximum transfer size during volatile market conditions Relay Vaults retired in late 2026, requiring manual user balance withdrawals	Suffered a $336,000 unbacked mint exploit on its Bitcoin bridge in September 2026 Cross-chain transactions remain vulnerable to network congestion delays on non-EVM chains High-volume routes depend heavily on protocol-owned pool liquidity
Best for	Fast native multi-chain transfers, Cross-chain stablecoin settlements, Developers building cross-chain checkout	Swapping between EVM networks and non-EVM chains, DeFi traders moving native Bitcoin and Solana assets, Developers integrating cross-chain swaps via SDK
