# ChainPort

> The ultimate cross-chain bridge

ChainPort lets users bridge tokens across multiple blockchains using a security-focused architecture with cold storage and multi-signature protection.

ChainPort is a cross-chain bridge that allows users to port tokens across multiple blockchain networks without reverting to the original chain. Users can bridge assets via wrapped asset, native token, stablecoin, and hybrid methods, while token issuers can access a private bridge with shared custody and customizable fee controls. Assets are secured through multi-signature cold storage vaults and MPC encryption.

## Products

- [ChainPort](https://thegrid.id/profiles/chainport): ChainPort is a cross-chain bridge enabling token transfers across multiple blockchain networks through wrapped asset bridging, native token bridging, external cross-chain protocol integrations, hybrid bridging for wrapped blue-chip tokens, and stablecoin bridging. The protocol stores up to 98% of assets in multi-signature cold storage via Fireblocks MPC encryption and Gnosis Safe, maintaining a small hot contract balance for active bridging. Users pay a fee per port in the ported token, PORTX, or the chain's native gas token. (Bridge, Live, Main Product)
- [ChainPort Private Bridge](https://thegrid.id/profiles/chainport): ChainPort Private Bridge is a managed bridge service for token issuers providing shared vault custody through a 3-of-5 multi-signature structure, splitting control between ChainPort's team, the token issuer, and an optional third-party trustee. Token issuers can customize bridging fees, configure address whitelisting and blacklisting, restrict porting directions, set per-transaction and per-address transfer limits, and enable automated 24/7 emergency freeze monitoring for their bridge integration. (Bridge, Live)
- [ChainPort Whitelabel Bridge](https://thegrid.id/profiles/chainport): ChainPort Whitelabel Bridge is an interoperability solution for EVM-compatible blockchains combining real-time exploit detection via predictive analytics and machine learning, generating a dynamic malicious actor exclusion list. The service provides automated emergency chain freeze capabilities, external insurance integration, DeFi and DEX security audits, OFAC-compliant address blocking, and multi-signature cold wallet freeze mechanisms for partner blockchain networks. (Cross-chain Infrastructure, Live)

## Assets

- [ChainPort Token (PORTX)](https://thegrid.id/profiles/chainport): PORTX is the utility token of ChainPort. It is used for paying discounted bridging fees when staked and earning a share of protocol fees collected across multiple blockchains. The token applies a deflationary mechanism where a portion of porting fees funds token buybacks, DEX liquidity provision, and staking rewards for holders. (Utility)
- [Wrapped ADA (WADA)](https://thegrid.id/profiles/chainport): WADA is a wrapped version of Cardano's ADA token issued by ChainPort. It is used for accessing ADA value in DeFi protocols and DEXs on EVM-compatible blockchains. Each token is backed 1:1 by ADA held in multi-signature cold storage vaults, with the original ADA released when WADA is burned through the ChainPort bridge. (Wrapped Tokens)
- [Wrapped STRAX (WSTRAX)](https://thegrid.id/profiles/chainport): WSTRAX is a wrapped version of Stratis's STRAX token issued by ChainPort. It is used for accessing STRAX value on Ethereum, BNB Chain, and Polygon, enabling trading on DEXs across those networks. Each token is backed 1:1 by STRAX held in ChainPort's cold storage vaults, redeemable by bridging WSTRAX back to the Stratis blockchain. (Wrapped Tokens)
- [Wrapped IRON (WIRON)](https://thegrid.id/profiles/chainport): WIRON is a wrapped version of Iron Fish's IRON token issued by ChainPort. It is used for accessing IRON value on EVM-compatible blockchains supported by ChainPort. Each token is backed 1:1 by IRON held in multi-signature cold storage vaults, redeemable by bridging WIRON back to the Iron Fish network through the ChainPort bridge. (Wrapped Tokens)
