Bridge Assets.
Zero Custody.
Full Control.
ZeroFi Bridge is a permissionless cross-chain protocol that wraps native assets like XMR and BTC into zAssets on EVM-compatible networks. No intermediaries. No custody risk. Just trustless transfers secured by zero-knowledge proofs.
// How it works
Three Steps. That's It.
ZeroFi Bridge wraps your native assets into ERC-20 zAssets on EVM networks. The process is fully trustless — no one holds your funds at any point.
Step 02
Send Native Asset
Transfer your native asset (XMR, BTC, or others) to the generated deposit address. The bridge waits for the required confirmations on the source network.
Step 03
Receive zAsset
Once confirmations are complete, the equivalent zAsset (zXMR, zBTC) is minted directly to your wallet on the destination chain. Fully backed 1:1.
// Bridge interface
Simple Interface. Powerful Protocol.
Mint zAssets from native assets or burn zAssets back to native — all from a single unified interface.
Deposit XMR, receive zXMR
Sign a deposit request, send Monero to the address the cluster returns, then claim your zXMR on-chain once the deposit is batched.
Step 1 of 3 — sign and request a deposit address

Everything you need to know about ZeroFi Bridge, zAssets, and cross-chain transfers.
ZeroFi Bridge is a non-custodial cross-chain bridge protocol that enables users to transfer assets like XMR and BTC across multiple networks. It wraps native assets into ERC-20 representations called zAssets (such as zXMR and zBTC), allowing them to be used across EVM-compatible ecosystems. The protocol is fully permissionless — no KYC, no account creation, no intermediaries. Every transfer is secured by zero-knowledge proofs and a distributed validator cluster.
ZeroFi Bridge operates in three steps. First, you connect your wallet and sign a deposit request — the protocol generates a unique deposit address on the source network. Second, you send your native asset (for example, XMR) to that address. Third, once the required confirmations are reached on the source chain, the equivalent zAsset (zXMR) is minted directly to your wallet on the destination network. The entire process is trustless — no intermediary ever holds your funds.
zAssets are 1:1 backed ERC-20 representations of native assets on EVM-compatible networks. For example, zXMR is a wrapped version of Monero's XMR on Ethereum, and zBTC is a wrapped version of Bitcoin's BTC. Each zAsset is fully collateralized — the total supply of zXMR always equals the amount of XMR held in the bridge reserve. zAssets can be transferred, traded, and used across any EVM-compatible protocol that supports ERC-20 tokens.
ZeroFi Bridge currently supports Monero (XMR) and Bitcoin (BTC) as source networks, with Ethereum as the primary destination network for zAssets. Additional EVM-compatible destinations — including Polygon, Arbitrum, and Base — are on the roadmap and will be added through community governance. The protocol is designed to be extensible, allowing new source and destination networks to be integrated over time.
Yes, completely. ZeroFi Bridge is fully non-custodial at every step. Your assets are secured by on-chain contracts and a distributed validator cluster — no team member, administrator, or third party has access to your funds at any point. You sign every transaction with your own keys and can redeem zAssets back to native assets at any time without permission from anyone.
Transfer speed depends on the source network's confirmation requirements. For XMR, the bridge requires 10 source-chain confirmations plus 10 sweep confirmations. For BTC, the confirmation count follows standard network requirements. Once all confirmations are reached, the zAsset is minted on the destination chain within seconds. Most transfers complete in under 30 minutes depending on network conditions.
ZeroFi Bridge charges a minimal, transparent bridge fee that is displayed before every transaction. Network fees on the source and destination chains apply separately and are set by the respective networks, not by ZeroFi. There are no hidden fees, no withdrawal fees, no deposit fees, and no management fees on any operation. All costs are clearly visible in the bridge interface before you confirm.
The minimum deposit varies by asset. For XMR, the minimum deposit is 0.01 XMR. Minimum amounts for other assets are displayed in the bridge interface next to the "Amount limits" section. These minimums ensure that the bridge fee does not represent a disproportionate cost relative to the transfer amount.
Yes. ZeroFi Bridge supports both minting (wrapping native assets into zAssets) and burning (redeeming zAssets back to native assets). To burn, switch to the "Burn" tab in the bridge interface, enter the amount of zXMR or zBTC you want to redeem, provide your native asset destination address, and confirm. The native asset will be sent from the bridge reserve to your address once the transaction is processed.
ZeroFi Bridge uses multiple layers of security: zero-knowledge cryptographic proofs for transaction verification, a distributed validator cluster with no single point of failure, fully audited open-source contracts, and a transparent on-chain reserve system. There are no admin keys or privileged upgrade mechanisms. All protocol changes go through governance and timelock processes.
No. ZeroFi Bridge is a fully permissionless protocol. No KYC, no account creation, no email address, no personal information of any kind. Just connect a compatible wallet and start using any feature immediately. Access is available to anyone with an EVM-compatible wallet and the native assets they want to bridge.
ZFI is the native governance and utility token of the ZeroFi protocol. ZFI holders can vote on protocol upgrades, fee parameters, new network integrations, and treasury allocations. ZFI is also used for validator staking and protocol incentives. Details about distribution and tokenomics are published through official ZeroFi channels.
For destination chains (EVM networks), ZeroFi Bridge supports MetaMask, WalletConnect-compatible wallets, and any EVM-compatible wallet. For source transactions, you can use any standard wallet for the respective network — for XMR, that includes the official Monero GUI/CLI wallet, Cake Wallet, and Monerujo. For BTC, any standard wallet supporting native transactions works.
ZeroFi Bridge transfers are designed to be atomic — they either complete or the funds remain on the source chain. If a transfer takes longer than expected due to network congestion, you can track its status on the ZeroFi Dashboard using your source transaction hash. The protocol includes recovery mechanisms for edge cases, and the community on Discord and Telegram can assist with any issues.
ZeroFi Bridge is unique in its focus on bringing non-EVM assets — particularly privacy-focused assets like XMR — into EVM ecosystems without centralized custody. Most bridges only connect EVM networks to each other. ZeroFi specifically solves the harder problem of bridging native non-EVM assets with zero-knowledge security, permissionless access, and full reserve transparency. There is no equivalent protocol offering this combination.
ZeroFi Bridge requires 10 source-chain confirmations and 10 sweep confirmations before minting any zAsset. This finality policy ensures that deposits are fully confirmed and irreversible on the source network before the corresponding zAsset is issued on the destination chain. Both deposit and payout operations wait for this depth on the source chain.
Yes — bridging XMR to Ethereum is ZeroFi's flagship route. You deposit XMR and receive zXMR (an ERC-20 token) on Ethereum, fully backed 1:1 by the XMR held in the bridge reserve. You can then use zXMR across any EVM-compatible protocol that supports ERC-20 tokens. This is the first permissionless, non-custodial way to bring Monero into the EVM ecosystem.
Yes. ZeroFi Bridge contracts and core protocol code are open-source and available on GitHub. The community is encouraged to review, audit, and contribute to the codebase. A bug bounty program rewards security researchers who find and responsibly disclose vulnerabilities. Transparency and verifiability are core principles of the ZeroFi protocol.
Yes. ZeroFi provides SDK documentation, API access, and integration guides for developers who want to embed cross-chain bridging capabilities into their own applications. The protocol offers permissionless API access — no application process, no approval needed. Full developer resources are available on GitHub and the ZeroFi documentation site.
Full documentation, developer APIs, SDK reference, and integration guides are available at docs.zerofi.io. ZeroFi also maintains an open-source GitHub repository, an active community on Discord and Telegram, and a blog on Medium with protocol updates and deep dives. For security inquiries, the bug bounty program details are available in the documentation.
