Wanchain

Wanchain is a decentralized blockchain interoperability protocol that connects 40+ independent networks -- including Bitcoin, Ethereum, Solana, Cardano, Polkadot, VeChain, XRP Ledger, and a wide range of EVM-compatible L2s -- through a network of permissionless bridge nodes secured by Secure Multiparty Computation (sMPC). Founded in 2017, it claims to have built the blockchain industry's first decentralized cross-chain bridge and has operated without a recorded exploit or significant downtime since launch.

How It Works

Wanchain's cross-chain transfers follow a lock-mint-burn-unlock model. When a user sends an asset from a source chain, it is locked in a smart contract controlled by the bridge node network. An equivalent representation is minted on the destination chain. When the user returns the asset, it is burned on the destination chain and unlocked on the source chain. No centralized custodian holds the assets at any point.

The security of the locked assets rests on a combination of sMPC and Threshold Signature Scheme (TSS), underpinned by Shamir's Secret Sharing cryptography. The private keys controlling locked funds are distributed across the bridge node set; no single node can unilaterally access them. Bridge nodes are re-elected monthly through a randomized process, which limits the window for long-term collusion and prevents any group of actors from permanently controlling the signing keys.

Nodes are also economically bonded: operators must stake WAN tokens in an amount that overcollateralizes the cross-chain assets they help secure. Malicious behavior results in stake slashing, aligning node incentives with honest operation.

Key Products

WanBridge is the core cross-chain transfer interface, supporting 40+ mainnets and 50+ bridgeable assets including ETH, BTC, USDT, USDC, DOT, SOL, WAN, and chain-native tokens. It handles both EVM chains (via standard Solidity bridges) and non-EVM chains such as Solana, Bitcoin, and XRP Ledger, which require specialized integrations.

XFlows enables native-to-native stablecoin transfers without creating wrapped intermediaries. The product integrates Circle's Cross-Chain Transfer Protocol (CCTP) on eight chains and supports native USDC on five additional networks. For Solana users, XFlows launched native USDC bridging in September 2024, connecting Solana's large USDC market to the rest of the Wanchain-connected ecosystem.

XStake is a multi-asset staking mechanism that allows participants to earn rewards denominated in BTC, ETH, USDT, and USDC -- not just WAN -- by delegating stake to bridge nodes or running nodes themselves.

XPort is a token porting solution for projects that want to distribute their token across multiple chains without managing separate bridge deployments.

On-chain DeFi applications built within the Wanchain ecosystem include WanSwap (an AMM DEX), WanLend (a lending protocol), and ZooKeeper Finance (a yield farming and NFT platform).

WAN Token

WAN is the native asset of the Wanchain L1 blockchain, a separate proof-of-stake chain that underpins the bridge infrastructure. It serves three primary functions. First, gas: WAN pays transaction fees on the Wanchain network. Second, bridge security: bridge node operators stake WAN to overcollateralize cross-chain locked assets; delegators can also stake WAN to earn rewards alongside node operators. Third, token burns: Wanchain's Convert n' Burn system routes a portion of bridge fees into the protocol treasury, which is used to periodically buy and burn WAN, creating deflationary pressure.

WAN is itself a bridgeable asset and can be moved across any network in the Wanchain ecosystem.

Solana Ecosystem Fit

Solana's non-EVM architecture historically made it difficult to connect to EVM-centric bridge networks. Wanchain integrated Solana in 2024, making it one of relatively few decentralized bridges to support native cross-chain flows to and from Solana. The initial integration launched with USDC XFlows, enabling native USDC transfers between Solana and 35+ connected chains without going through a wrapped-token intermediary.

The VeChain integration, relaunched in August 2026, also includes Solana as one of its bridge endpoints, allowing VET, VTHO, B3TR, ETH, BTC, USDC, USDT, SOL, XRP, and WAN to move between VeChain, Ethereum, Bitcoin, Solana, Wanchain, and XRP Ledger.

For Solana-native users, Wanchain provides a decentralized route to move assets out of or into the Solana ecosystem without relying on centralized exchange withdrawals or custodial bridge providers.

Security Track Record

Wanchain's most frequently cited credential is its security track record: more than seven years of mainnet operation since late 2017, with no recorded exploit or material downtime. The sMPC + TSS security model was specifically designed to eliminate single points of failure that have caused major losses in other bridge architectures.

Bridge node rotation through monthly, randomized re-election and the overcollateralization requirement are structural controls that distinguish Wanchain's model from bridges that use fixed multisig key holders or rely on a small number of validator sets.

No major third-party audit reports are highlighted prominently in the public documentation, though the protocol's longevity and lack of exploits are the primary security arguments made by the team.

Background

Wanchain was founded in 2017 and is backed by the Wanchain Foundation. The project predates the cross-chain bridge boom of 2020-2022 and has maintained development continuity through multiple market cycles. The codebase is open-source and maintained on GitHub. The team's EVM-compatible L1 supports Solidity development and is accessible via standard developer tooling, lowering the barrier for application developers who want to build cross-chain functionality on top of the protocol.
