As on-chain privacy and seamless interoperability become cornerstones of DeFi, Manta Bridge has emerged as the premier protocol for confidential, non-custodial transfers of tokens, NFTs, and arbitrary data across multiple blockchains. By combining zero-knowledge proofs (zk-SNARKs) with a decentralized relayer network, Manta Bridge shields transaction details while preserving strict 1:1 asset parity.

Manta Bridge Key Features

Zero-Knowledge Privacy
Complete confidentiality for transaction amounts and participant addresses, with optional selective disclosure for auditing.

Multi-Chain Support
Native interoperability across EVM chains (Ethereum, BNB Chain, Polygon), Polkadot parachains, and Cosmos zones via IBC adapters.

NFT & Data Bridging
Transfers ERC-721/1155 and SPL NFTs with metadata preservation, plus arbitrary messaging for cross-chain governance and DeFi composability.

High Throughput & Low Gas
zk-Rollup batching handles thousands of shield events per minute, minimizing on-chain gas costs.

Decentralized Relayers
Permissionless nodes stake MANTA tokens; honest participation earns fees, and misbehavior leads to stake slashing.

Developer Tooling
Comprehensive JavaScript/TypeScript SDK, Rust SDK, REST APIs, and CLI utilities for seamless integration.

How to Use Manta Bridge

Connect Your Wallet
Navigate to the Manta Bridge portal and connect via MetaMask (EVM), Polkadot.js (parachains), or WalletConnect.

Choose Source & Destination
Select your source chain (e.g., Ethereum) and destination chain (e.g., BNB Chain).

Select Asset & Amount
Pick an ERC-20 token or NFT and enter the shielded quantity. The client creates a zk-SNARK proof locally.

Approve & Submit Shield
Authorize the shield contract and submit the lock transaction on the source chain. Wait for confirmations; then relayers generate the proof.

Redeem on Destination
Once the zk-SNARK proof is available, click “Redeem” to mint or release your asset on the destination chain.
