Wanchain

Wanchain is a decentralized blockchain interoperability platform that enables direct cross-chain communication between otherwise siloed blockchain networks. Founded in 2017, it describes itself as the industry's first decentralized cross-chain bridge provider. Rather than routing transfers through a central hub or relay chain, Wanchain builds direct bridges between networks — secured entirely by cryptography and economic staking, not by a trusted third party.

How It Works

Wanchain bridges use a lock-mint-burn-unlock mechanism. When a user sends an asset from a source chain, it is locked in a smart contract on that chain; an equivalent wrapped or native representation is minted on the destination chain. When the user redeems, the destination-chain token is burned and the original asset is released. For native asset transfers — where no wrapping is desired — Wanchain's XFlows protocol handles native-to-native transformations, so users receive the actual native token rather than a wrapped derivative.

The security underpinning this mechanism is Wanchain's use of Secure Multiparty Computation (sMPC) combined with a Threshold Signature Scheme (TSS). Private keys controlling locked assets are never held by a single party; instead, they are split across a distributed group of bridge nodes using Shamir's Secret Sharing. A valid signature can only be produced when a sufficient threshold of nodes cooperate, meaning no single node — nor any small coalition below the threshold — can move locked funds unilaterally.

Bridge nodes are permissionless and non-custodial: anyone can operate one. Node sets are rotated and re-elected on a monthly basis to prevent entrenchment. Operators are required to stake WAN coins as overcollateral for the cross-chain assets their node group manages, creating an economic deterrent against dishonest behavior. If a node acts maliciously, its staked collateral is at risk.

Wanchain's own blockchain runs on Galaxy Consensus, a Proof of Stake protocol derived from Cardano's Ouroboros with enhancements to random number generation and block production. A Random Number Proposer (RNP) group uses commitments, zero-knowledge proofs, and distributed secret sharing to produce unpredictable randomness that drives the Unique Leader Selection algorithm for block production.

Products and Services

WanBridge is the primary interface for cross-chain asset transfers, supporting fungible tokens and NFTs across Wanchain's full network of 40+ connected blockchains.

XFlows is Wanchain's native-to-native bridging protocol. Rather than issuing wrapped tokens, XFlows delivers the actual native asset on the destination chain. At launch with Solana, XFlows initially supported USDC across 13 blockchains — eliminating the wrapped USDC problem that has historically fragmented liquidity.

XStake is a staking platform built on top of the cross-chain infrastructure, allowing users to stake xWAN and earn rewards denominated in BTC, ETH, USDT, and USDC — assets that originate on other chains and flow through Wanchain's bridge network.

NFT bridges are also supported, with attribute preservation for non-fungible tokens moving between chains.

Solana Integration

Wanchain launched its Solana bridge in September 2024, with full USDC XFlows support rolling out on October 15, 2024. The integration was technically significant because Solana's non-EVM architecture — specifically its account-based model versus Cardano or other UTXO chains, and its distinct program structure — required Wanchain to handle model conversion that EVM-to-EVM bridges do not face. The Solana bridge connects to all 35+ other chains in Wanchain's network.

Wanchain CEO Temujin Louie cited Solana's ecosystem momentum as motivation for the integration. The broader Solana ecosystem was experiencing strong growth in daily active users through 2024, with major payment providers entering the network. Wanchain followed its earlier Cardano and Polkadot integrations — which contributed to observable ecosystem activity including a 40% increase in Cardano on-chain activity — with Solana as the next major non-EVM addition.

The initial asset supported was native USDC via XFlows, with native USDT planned as a subsequent addition.

Network Coverage

As of 2025, Wanchain connects more than 40 blockchains. These include major Layer 1s (Bitcoin, Ethereum, Solana, Cardano, XRP Ledger, Avalanche, Polkadot), Ethereum Layer 2s (Arbitrum, Polygon), and other ecosystems (BNB Chain, Fantom, Moonbeam, Moonriver, Litecoin, Sonic, Unichain, VeChain). In May 2025, VeChain partnered with Wanchain to launch a first-ever cross-chain bridge connecting VeChain to Ethereum, Bitcoin, and Solana.

WAN Token

WAN is Wanchain's native coin. Its total supply is 210 million tokens, distributed across team (10%), foundation (30%), node rewards (40%), and ecosystem development (20%). WAN is used to pay transaction fees on the Wanchain blockchain, and bridge node operators must stake WAN to participate in bridge security. Delegators who back node operators also earn WAN rewards. WAN holders can participate in governance.

Security Track Record

Wanchain claims a security record of more than seven years of operation without a hack or exploit affecting its bridge infrastructure. The platform has operated without downtime across this period. Third-party audits are conducted for specific new deployments — the VeChain bridge launch in 2025, for example, included a comprehensive audit by an external firm prior to launch — though specific audit firm names and report links are not prominently published on the main website.

Background

Wanchain was founded in 2017, making it one of the earliest dedicated cross-chain interoperability projects in the blockchain industry. The project predates most of the interoperability solutions that emerged during the 2020–2021 DeFi expansion and has positioned the longevity of its infrastructure as a differentiator. Temujin Louie serves as CEO.
