XP.network
Project Description
The first of the kind NFT multi-chain bridge connecting a wide range of EVM to a number of Non-EVM chains. At the moment of writing, the bridge allows transferring NFTs to and from:
Ethereum
Binance Smart Chain
Avalanche
Polygon
Algorand
Fantom
Tron
Elrond
Tezos
Velas
IoTeX
xDai
Fuse
Problem / Solution
Secret Network is becoming an important player in the blockchain industry. Its token already occupies #86th place in the coin ranking. But much more importantly, Secret Network is developing a rich NFT ecosystem populated with professionally developed Marketplaces, promising NFT projects, and talented content providers.
However, they will all be detached from the global NFT market and will require a gateway for their assets for entering and exiting the blockchain. XP Network NFT Bridge is the Silk Road or the Spice trade route of today's NFT industry. We connect the otherwise isolated markets whose potential is limited to the insular communities of individual chains.
The bridge makes cross-chain marketplaces, NFT oriented games, and defi projects possible. It integrates Secret Network to the global NFT ecosystem opening it for otherwise impossible possibilities of development and growth.
Detailed product description
Our groundbreaking technology has several advantages. We support a wide range of EVM and Non-EVM protocols at once
The intuitive interface of the applications ensures a pleasant user experience
We have developed a cross-chain NFT listing tool
Our JavaScript API library allows partnered dApps to use our instruments from any programming language behind the scenes (TypeScript, Python, C#, Java, C++, Swift, etc.)
We work with multiple token standards and conveniently convert one standard to another while transferring assets across networks.
We allow our users to select the tokens they want to pay the transaction fees with, taking the burden of currency conversion.
We support transfers in batches to save on transaction fees.
We have set up a layered security system around our solutions to provide maximal protection of the assets of our users.
We allow transferring NFTs with the smart contract logic they had in the original chain.
Go-to-Market plan
The bridge has been built to satisfy the needs of different groups of users on Secret Network. Therefore, it consists of several components.
The Bridge User Interface is available at https://bridge.xp.network. It is designed for non-coding users such as NFT owners, traders, investors, collectors, and artistic content creators.
The cross-chain games with teams of players spread across the blockchains whose raging armies of militant invaders or peaceful treasure hunters and gold miners can travel from one blockchain to another, either gaining value or getting annihilated by superior forces of the aborigen inhabitants.
Cross-chain marketplaces save hundreds of thousands of dollars and developer-hours by using the ever-growing library allowing the users to buy Solana NFTs from Elrond and pay for the assets and the transaction fees with a currency of the customer's choice.
NFT Projects preferring global over local presence expose the freshly minted collections with groundbreaking logic or breathtaking design to tens or, eventually, hundreds of communities at once enjoying previously unprecedented demand and sales volumes.
The bridge REST API service supports developers in Python, Java, C#, C++, or any other programming languages to use the functionality of the bridge by calling POST requests with the function call parameters stored in the body of the requests. In return, the service returns valid for the chain of interest but unsigned transactions the users can sign and submit from the application of the third parties.
Value capture for Secret Network ecosystem
XP Network NFT Bridge is the only NFT gateway for several chains (Elrond, Algorand, Tezos, Velas, Fuse) and by keeping integrating more and more chains we're becoming a one-stop solution for the global NFT ecosystem.
In order for wrapped NFTs to be treated as "native" on foreign chains, they must be minted according to the standard of the target chains. The bridge converts Native NFTs of the chain of departure to the following standards on the chain of destination:
ERC-721/BEP-721/TRC-721/HRC-721 in the EVM compatible blockchains
ERC-1155/BEP-1155/TRC-1155/HRC-1155 in the EVM compatible blockchains
The currently functioning NFT Bridge is a living example of the team's maturity and readiness for integrating Secret Network into the global NFT family.
Our team has already bridged 10+ chains. For many chains our bridge is the only one allowing to transfer NFTs to/from:
We will develop smart contracts that will: 0. Research about Secret Network standards and other factors & protocols that distinguish it from other chains 1. Support Singe & Batch transfers 2. Freeze/Unfreeze Native NFTs 3. Mint/Burn wrapped NFTs 4. Withdraw the TX fees on the target chain in native tokens
Milestone 2 — Smart Contract Development
Length
Deliverable
Specification
0.5 months
Smart Contracts
We will develop smart contracts that will: 5. Trust the multisig of the bridge oracle validators 6. Whitelist NFT smart contracts 7. Pause/Unpause for maintenance or if compromised 8. Reimburse the bridge validators their expenses
Milestone 3 — Testing & Documenting
Length
Deliverable
Specification
0.5 month
Tests & Documentation
1. We will provide both inline documentation of the code and a basic tutorial that can interact with the deployed smart contracts and backend service. 2. The code will have proper unit-test coverage of 85% to ensure functionality and robustness. In the guide, we will describe how to run these tests preparing for auditing 3. Deploying and testing the contracts in the testnet environment
Milestone 4 — Integrating into the Live Bridge
Length
Deliverable
Specification
1 month
Validators, Backend, Frontend
1. Developing validation logic relevant for the Secret Network part of the bridge 2. Adding Secret Network to the Bridge NFT-Indexer 3. Integrating TX fee estimation 4. Plugging Secret Network in the heartbeat 5. Integrating with a Secret Network RPC node 6. Integrating Secret Network in the bridge UI 7. Deploying smart contracts 8. Adding Secret Network to the bridge JS library 9. Adding access to Secret Network from the REST API 10. Adding Secret Network to the bridge widget
We would be willing to consider part payment in SCRTs, up to 100%.
Future Plans
Our long term plans include:
Mainnet integration to Cardano, Solana, Polkadot ecosystem, other Cosmos ecosystem chains, EOS compatible chains, NEO
Forged NFT detection on all the bridged chains
NFT explorer for finding NFT’s with deleted storage
NFT meta backup to secure transactions
Distributed NFT’s hosting (better than IPFS)
NFT Search (search by any parameter)
Retention protection tool
