Cross-chain bridges are essential infrastructure, and 2025–2026 reshaped the field: Stargate was acquired by the LayerZero Foundation, Synapse handed its protocol to a community DAO while its team pivoted away, and intent-based designs made raw TVL a misleading yardstick on its own. As of July 2026, Wormhole's Portal bridge holds by far the most value — roughly $2.44B per DefiLlama — while Across and deBridge move tens of billions in volume with almost no locked capital. Axelar anchors the Cosmos-style interop camp, and veterans Hop and Synapse illustrate how quickly bridge liquidity migrates.
How we picked
- TVL from DefiLlama, fetched July 12, 2026 — the primary metric, as before.
- Cumulative volume — protocol-reported figures from official sites and explorers, flagged as self-reported; for intent-based bridges (Across, deBridge) volume outweighs TVL, which their designs keep near zero.
- Audit and security record — audit firms from official docs, plus every major exploit or averted incident, stated plainly.
- Operational status through 2025–2026 — acquisitions, pivots and wind-downs verified against primary announcements.
Comparison table (July 2026)
| Protocol | TVL / volume (Jul 2026) | Chains | Audits | Key mechanism |
|---|---|---|---|---|
| Wormhole Portal | $2.44B TVL · $68B lifetime | 45+ | 29 audits: Trail of Bits, Zellic, OtterSec, Neodyme, Halborn + | 19 Guardians sign VAAs (13/19 quorum) |
| Stargate | ~$82M TVL · $63B+ cumulative | ~26 pools, 80+ reachable | Zellic, OtterSec (V2) | Unified liquidity pools + Hydra OFT over LayerZero |
| Across | ~$21M TVL · $36B+ cumulative | 27 | OpenZeppelin | Intents: relayers front funds, UMA optimistic settlement |
| Axelar | ~$135M TVL · ~$13.3B cumulative | 70+ | NCC Group, Cure53, Ackee, CertiK, Least Authority + | Cosmos PoS validator chain + GMP |
| deBridge | ~$2M TVL · $20B+ cumulative | 25+ | 26+ audits: Halborn, Zokyo, Ackee, Neodyme | Zero-TVL intents; solvers fill per order |
| Synapse | ~$12M TVL · $50B settled | 19 | Not named in official docs | nUSD/nETH pools + optimistic guards; now Cortex DAO |
| Hop | ~$3M TVL · $6B+ cumulative | 7 | Solidified, Monoceros Alpha | Bonders front liquidity; hTokens + AMMs |

Wormhole (Portal)
$2.44B TVL (Jul 2026)
Generalized cross-chain messaging network whose Portal token bridge holds the deepest locked liquidity of any bridge. 19 Guardian nodes observe events and a 13-of-19 quorum signs the VAA attestations that move assets.
Portal's ~$2.44B TVL (DefiLlama, July 2026) and wormhole.com's claimed $68B lifetime volume across 45+ chains put it first on scale. The security history is double-edged: in February 2022 an attacker minted 120,000 wETH (~$325M) via a deprecated signature check — Jump Trading replaced the funds — and Wormhole has since accumulated 29 third-party audits (Trail of Bits, Zellic, OtterSec, Neodyme and others) plus a $5M Immunefi bounty. Its 2025 release was Wormhole Settlement (February), an intent-based transfer suite.

#2
Stargate
~$82M TVL · $63B+ volume
LayerZero-based unified-liquidity bridge using shared pools. v2 introduced the Hydra design — native assets locked in core pools mint OFT representations on connected chains, with fee tiers and fast or economy paths.
Stargate's pooled TVL is now modest — about $72M in V2 plus $10M in V1 as of July 2026 (DefiLlama) — but throughput remains heavyweight: over $63B cumulative across 50M+ transactions, with roughly $4B in July 2025 alone. Zellic and OtterSec audited V2, and the protocol reports no serious security incident since its March 2022 launch. The big 2025 event was corporate: the LayerZero Foundation acquired Stargate for $110M in a STG-to-ZRO swap, approved by the DAO in August 2025 over Wormhole's $120M counter-bid, dissolving the Stargate DAO into LayerZero.

#3
Across Protocol
$36B+ volume · ~$21M TVL
Intent-based bridge from the UMA team: competitive relayers front capital on the destination chain, and a Dataworker bundles fills into settlement proposals verified by UMA's Optimistic Oracle. Powers bridging inside Uniswap and Coinbase Wallet.
Across is the strongest proof that intent designs need almost no locked capital: about $21M sits in its Ethereum hub pool while cumulative volume passed $36B across 5M users (across.to, July 2026). Every major contract release — V2, V3 and incrementals — was audited by OpenZeppelin, and the protocol advertises zero exploits since its November 2021 launch. Across Prime, published with Paradigm in May 2025, proposes bonded relayers to cut capital costs further.

#4
Axelar
~$135M TVL (Jul 2026)
Proof-of-stake interoperability chain built on the Cosmos SDK. Its validator set secures Gateway contracts on each connected chain, and General Message Passing (GMP) routes arbitrary data and contract calls, not just tokens.
Axelar holds about $135M TVL (DefiLlama, July 2026) with roughly $13.3B in cumulative volume per its Axelarscan explorer ($6.3B GMP plus $7.0B token transfers). Its public audit repository spans NCC Group, Cure53, Ackee, CertiK, Least Authority, Halborn and more. The February 2025 Cobalt upgrade burned 98% of network gas fees to offset validator rewards as connections scale. In June 2026 Secret Network's Axelar-connected IBC bridge suffered a $4.67M infinite-mint exploit; the flaw was in Secret's modified contract and Axelar's core was unaffected — a reminder of integration risk at the edges.

#5
deBridge
$20B+ volume · ~$2M TVL
Intent-based cross-chain liquidity protocol. DLN (deBridge Liquidity Network) fills orders through competitive solvers with no shared pools — "pipes, not pools" — plus generic messaging via deBridge Messaging.
deBridge's ~$2M TVL is the design working as intended: solvers provide liquidity per order, and cumulative volume tops $20B on 25+ chains (official docs, July 2026). The team reports 26+ audits — including Halborn, Zokyo, Ackee and Neodyme — and zero security incidents since launch. On mainnet since early 2022, its notable 2025 move was a Reserve Fund routing 100% of protocol revenue (~$10M annualized) into open-market DBR buybacks.

#6
Synapse Protocol
~$12M TVL · $50B settled
Multi-chain liquidity router. Synapse Bridge handles canonical wrapping, stablecoin swaps via nexus tokens (nUSD/nETH backed by Ethereum pools), and a native CCTP router for USDC, with optimistic guard-based fraud proofs.
Synapse settled over $50B for 2M+ users during its run (official docs) and its validators averted an ~$8M exploit in November 2021 with no user funds lost — though its docs never named audit firms, a transparency gap worth knowing. The decisive 2025 change was governance: under SIP-43 (November 24, 2025), Synapse Labs transferred the protocol to the community-run Cortex DAO, while the core team pivoted to Hypercall, an options venue on Hyperliquid. The bridge still operates (~$12M TVL, July 2026, DefiLlama), but active development has moved on — hence its position here.

#7
Hop Protocol
~$3M TVL (Jul 2026)
L2-native rollup-to-rollup bridge using bonders and AMMs (hToken pools). Optimized for moving canonical assets like ETH and USDC between Ethereum and L2s with low latency.
Hop's design — bonders front destination liquidity against 110% collateral with a 24-hour challenge window — has run without a reported exploit since July 2021, with audits by Solidified and Monoceros Alpha and over $6B bridged lifetime per its DAO's January 2025 report. But it is in wind-down-and-rebuild mode: V1 incentives are being phased out, V2 remains on testnet awaiting external audits, and the newer "Hop Rails" design repo was still active in January 2026. At ~$3M TVL (DefiLlama, July 2026) it closes the list — a clean security record, minimal current liquidity.
