Major cross-chain messaging protocol with 30+ chains but marred by a $320M exploit in 2022.

Portal Bridge, powered by Wormhole's cross-chain protocol, is one of the most widely integrated bridges in crypto despite its $320M hack history, now backed by the W token and enhanced guardian security model.

High-performance cross-chain bridge with intent-based architecture — growing rapidly in the Solana corridor with strong tech but nascent token economics.

Pioneer of xERC20 and noncustodial bridging, now Everclear clearing layer — strong technical contributions but rebrand and competitive pressure create uncertainty.

Pioneer L2-to-L2 bridge using Bonders and AMMs — built for Ethereum's rollup-centric future.

Fast L2-to-L2 bridge using a Maker model — heavily used for rollup transfers but no token yet and centralized Maker infrastructure.

Bridge aggregator and chain abstraction middleware — well-adopted infrastructure layer but competes in a crowded aggregator market.

Axelar-powered cross-chain router enabling one-click any-to-any token swaps across chains — strong UX built on solid infrastructure.

Union brings ZK-verified IBC to connect Cosmos and Ethereum trustlessly — technically impressive and addresses a real gap, but adoption is early and the bridge market is fiercely competitive.

The W token for Wormhole cross-chain messaging protocol -- massive adoption but haunted by the $320M exploit and a token with unclear value capture.

Permissionless interoperability protocol with modular security — anyone can deploy it on any chain, and applications choose their own security model. Strong design with growing reach.

Veteran cross-chain infrastructure with cBridge and messaging — technically solid but struggling for differentiation in a consolidating bridge market.

Trustless Bitcoin bridge on Polkadot using over-collateralized vaults — technically impressive but hampered by Polkadot's ecosystem limitations.

Bridge + DEX aggregator routing across all major protocols — strong adoption as backend infrastructure, but aggregation adds its own smart contract risk layer.

Atomic swap stablecoin bridge — cryptographically trustless design with broad chain support, but niche focus and limited token utility.

Mid-tier cross-chain bridge with AMM-based swaps and messaging — functional but facing intense competition and bridge-sector security risks.

Socket's bridge aggregator finding optimal cross-chain routes. Best-rate guarantee across multiple bridges but inherits each bridge's risks.

Rebuilt after the infamous $620M Lazarus Group hack — improved security but the historical exploit demands permanent caution.

ZK-proof-based multi-chain aggregation protocol with a novel Layer 3 approach -- technically ambitious but early-stage with limited adoption and unproven tokenomics.

Biconomy's instant bridge — fast and cheap cross-chain transfers via liquidity pools, but centralized operation and growing competition from intent-based bridges.

Router Protocol's fast bridge using forwarder model — near-instant transfers with decent multi-chain coverage, but centralized forwarder infrastructure and competitive market.

Native cross-chain swaps with JIT AMM — technically impressive decentralized bridge enabling BTC↔ETH without wrapped tokens, one of the most ambitious bridge designs.

Cross-chain swap protocol with solid UX and multi-chain coverage — functional product with growing volume but centralized relayers and modest scale.

Instant cross-chain bridge using relayer fills — fastest bridge UX in crypto with strong security model, avoiding the lock-and-mint risks that have plagued bridges.

StarkEx-powered bridge and DeFi aggregator — validity proof security is a genuine advantage, but rebrand confusion and modest adoption limit growth.

Stablecoin-focused multi-chain bridge — useful niche product but small scale, prior exploit, and centralized operation.

L2-focused cross-chain bridge with fast transfers between Ethereum rollups. Strong adoption but centralized bridge model.

Token porting bridge focused on security and simplicity — custodial but functional, helping projects expand tokens cross-chain without a meaningful native token.

Cross-chain IBC infrastructure aiming to unify Polkadot, Cosmos, and Ethereum — technically ambitious but adoption has not materialized.

Cosmos-Ethereum bridge chain that merged with Althea Network — technically sound but low adoption and an uncertain future after pivoting to ISP infrastructure.

Intent-based cross-chain trading via competitive market makers — technically superior to lock-and-mint bridges with no pooled liquidity risk, but adoption is still growing and maker competition is limited.

Kusama canary network for Composable Finance's IBC bridging — experimental cross-chain infrastructure with negligible adoption and thin liquidity.

Bringing Cosmos IBC to Ethereum rollups — technically elegant approach to L2 interoperability leveraging the most proven cross-chain protocol, but very early stage with minimal live usage.

Cross-chain swap aggregator with 60+ chain support — one of the more comprehensive bridge aggregators. Real usage, real product, but thin margins in a commoditized space.

Cross-chain route optimizer — aggregates bridges and DEXs to find best cross-chain swap rates. Useful service but the bridge aggregator space is crowded and commoditized.

Cross-chain bridge destroyed by a $190M exploit caused by a routine upgrade error — a defining cautionary tale of bridge security failures in crypto.

Cross-chain bridge infamous for the $611M hack (funds returned) and a second 2023 exploit — trust destroyed, minimal usage, a bridge security cautionary tale.

DEAD bridge — $130M+ drained in 2023 collapse following CEO arrest. Complete failure. Do not interact. Irrecoverable loss for users.

Dead cross-chain bridge — associated with defunct BridgeMutual insurance protocol, no meaningful activity or development remaining.

Harmony's bridge hacked for $100M by North Korea's Lazarus Group through a 2-of-5 multisig compromise. The hack killed Harmony's DeFi ecosystem and stands as a defining bridge security failure.
