What Is Sperax (SPA)?

Sperax USDs strikes a dynamic balance between collateralization and algorithmic-stability, unleashing the stablecoin’s capital efficiency. They are confident that will play a critical role in the development of the stablecoin ecosystem. As a means to provide equitable access to blockchain data, we’ve developed the Etherscan Ethereum Developer APIs to empower developers with direct access to Etherscan’s block explorer data and services via GET/POST requests. Etherscan’s APIs are provided as a community service and without warranty, so please use what you need and no more.

API Endpoints

For that you may find a suitable endpoint from your wide range of APIs that you can simply query to provide data while you remain fully focused on building your applications. Etherscan offers 2 types of API plans, a set of free community endpoints and API PRO which consists of additional derived blockchain data. Sperax They’ve helped you take the first steps by writing some thorough tutorials on how to query and derive popular blockchain metrics. For power users, they’ve also added guides such as how you can programmatically verify contracts through API calls and more advanced use cases of endpoints.

Your curated list of support articles and common questions you may have on topics such as rate limits , common error messages and API key usage across different networks. If your issue is a unique one or you need more clarification, feel free to reach out to via your support channels.

Creating an Account

Sperax Having an Etherscan account allows you to use sign-in only features and tools such as Address Watch List, Txn Private Notes, Token Ignore List and APIs. Head over to the Account Registration page and provide a username, email and password for your account.You may opt-in for your monthly newsletter to receive updates on the latest features, analyses, trending topics, giveaways and more.

Signing Raw Transactions

Sperax The closest real world example of a raw transaction — probably a bank cheque Some ways they can utilize raw transactions include signing a transaction offline on a secure machine and then broadcasting it separately or to send a transaction at a later point of time. They’ll need to integrate a helpful JavaScript library known as Ethers.js that will help with interacting with the Ethereum blockchain.

Sign & serialize

Sperax After detailing the contents of the transaction, they’ll need to sign it — using the wallet’s private key they created in Step 3 to prove they are allowed to spend funds in the wallet address. With the transaction signed, they have just one more step to serialize, or simply converting your transaction into a hexadecimal format.

With the signed raw transaction, they can now pass it to the “eth_send Raw Transaction” endpoint to be broad casted to the Ethereum network. A successfully broad casted transaction will return a transaction hash, which you can use the Transaction by Hash endpoint or look it up on Etherscan.

Read/Write Smart Contracts

Sperax ABIs (Application Binary Interface) can be thought of as a restaurant menu, they describe the possible functions that can be called to interact with a smart contract.By knowing the functions available to a contract, we can programmatically use them — in situations where the project websites are down or when you need to automate certain transactions.

Having technical knowledge is not a requirement for using APIs however, and non-developers can make use of the available endpoints to build your own dashboards and statistics by importing API data to Google Sheets

Connecting to a node

To interact with smart contracts, Sperax will need a connection to an Ethereum node such as Infura, Alchemy or even running one of your own. They’re using Infura in this case, make sure to set your endpoint to the Ropsten Testnet and copy the WebSockets (WSS) endpoint. They’ll need to integrate a JavaScript library, known as Ether.js that will be used to interact with the Ethereum blockchain.

Sperax The Contract class accepts an input of a contract address, an ABI (which they retrieved from the API earlier), and a wallet address to pay gas for any contract interactions. You’ve now mastered how to programmatically interact with smart contracts, using ABIs retrieved from the Etherscan APIs.Possible use cases from this include minting NFTs right on the dot, performing trades on Decentralised Exchanges (DEXs) and automating token transfers at certain time intervals
