CrossCurve
Cross Chain Bridge · Taiko, xDai, BNB Chain +17
CrossCurve, formerly EYWA, is a cross-chain swap and bridge protocol that combines Curve-style pools with a multi-messenger design. It suffered a bridge exploit in early 2026, and its TVL is now very small, so caution is warranted.
ScoreScore 4.5 out of 10TVL $34.7K−4.3% - 19
Allbridge Core
Cross Chain Bridge · Sui, Solana, Stellar +11
Allbridge Core is a cross-chain bridge that swaps dollar stablecoins such as USDT and USDC between blockchains using liquidity pools on each network. It suits users moving stablecoins between supported chains, but the team has reported a $1.65M withdrawal from its pools, which should weigh heavily on any decision to use it.

RelayChain
Cross Chain Bridge · Optimism, Polygon, Ethereum +10
RelayChain is a crypto bridge described as connecting users to cross-chain opportunities across multiple networks. Its listed network coverage is broad, but current availability, fees and security details need careful verification.

How we ranked them
Reviewed dApps come first. Each DappsAtlas review scores security, ease of use, fees and features from 0 to 10 using public facts such as audits, documentation and on-chain data; the overall score orders the list, with total value locked as the tie-breaker. Projects we have not reviewed yet follow, ordered by total value locked. Scores are never sold.
