A Step-by-Step Guide for Developers Building Multi-Chain Crypto Apps

In today's fast-paced blockchain world, building a crypto application that seamlessly interacts with multiple networks shouldn't take hours or require juggling endless APIs.

In today’s rapidly evolving crypto landscape, building an application that seamlessly integrates with multiple chains shouldn’t be a time-consuming or complex process. Yet, many developers still face this challenge, juggling various APIs and spending hours to achieve seamless multi-chain support.

However, with OmniBit API, you can effortlessly power up your project with Ethereum, Solana, Tron, and over 20 other networks in a flash. This step-by-step guide will take you through the process in an engaging, concise, and developer-focused manner.

As you embark on selecting the optimal API for your crypto application, several key capabilities are crucial. These include:

1. Aggregated Data: Effortlessly access data from multiple blockchains and exchanges in one centralized location.

2. Up-to-Date Mapping: Continuously update token and contract mapping in real-time, going beyond traditional aggregators.

3. Low Latency: Enjoy blazing-fast and reliable responses for efficient integration and optimal performance.

OmniBit API ticks all these boxes with its single, high-performance solution. It integrates over 20 blockchains and both centralized and decentralized exchanges, all covered by a comprehensive token mapping system.

Getting started is incredibly easy:

1. Create an Account: Quickly register for free at https://omnibit.aio.exchange/.

2. Generate Your API Key: Instantly unlock access to aggregated, real-time blockchain data through your account dashboard.

3. Start Building: Begin integrating and scaling your multi-chain crypto application within minutes, not hours.

2. Exploring Supported Networks

To discover which networks are supported by OmniBit API, you can use the following endpoint to retrieve a list of available blockchains:

Endpoint:

GET /v1/blockchain/networks

Response Example:

{

“data”: [

{ "network": "ETH", "description": "Ethereum" , ... },

{ "network": "SOL", "description": "Solana" , ... },

{ "network": "TRX", "description": "Tron" , ... }

// ... additional networks

],

...

}

This simple call provides all the necessary network identifiers for subsequent requests, keeping your multi-chain support as streamlined as possible.

At the time of writing, the following networks are supported with abstraction under a single endpoint: Ethereum, Binance Smart Chain, Polygon, Avalanche C-Chain, Solana, TRON, Bitcoin Segwit, Bitcoin, Bitcoin Cash, Litecoin, Litecoin Segwit, Ripple, Sonic, Optimism, Mantle, HTX Eco Chain, Flare, Filecoin, Chiliz, Celo.

3. Selecting Tokens with Confidence

Token symbols can sometimes be ambiguous. For instance, one token symbol, like HOT, might have multiple contracts on different exchanges. However, OmniBit API allows for contract-address queries that accurately map to token symbols.

To quickly demonstrate, let’s use this endpoint:

Example Request:

GET /v1/tokeninformation/symbols/SOL

Example Response:

{

"data": {

"tokenId": 38105,

"name": "Solana",

"symbol": "SOL",

"marketCap": 68434965207.68254,

"description": "Solana (SOL) is a cryptocurrency launched in 2020...",

"logoURL": "https://source1.com/token/img/32x32/solana.png",

"website": "https://solana.com",

"rank": 6,

"dilutedMarketCap": 83260303222.58763,

"aioConnectedExchanges": 12,

"networks": [

{

"network": "SPL",

"networkName": "Solana",

"contractAddress": "SOLANA",

"isAvailable": true

}

],

"isFiat": false

},

...

}

This endpoint ensures that your application supports the right tokens with precision.

4. Retrieving Transaction Details

With OmniBit API’s standardized transaction endpoint, fetching details about transfers, native coins, or NFTs is straightforward. One universal call works across networks.

Example Request:

GET /v1/blockchain/transactioninfo/ERC20/0x8f1191513d568aba769063985ace4b2acce621bd90a41a02f7cf956
