Question 1

How do I send a payment transaction with AlgoSDK?

Accepted Answer

Use functions like `algosdk.makePaymentTxnWithSuggestedParams` to construct the transaction, sign it with a private key, and submit via an `Algodv2` client. Detailed examples are in the documentation, but require a local node for testing.

Question 2

AlgoSDK vs community wrappers for Algorand?

Accepted Answer

AlgoSDK is the official library with guaranteed protocol compatibility and full feature support, while community wrappers might offer simpler APIs but lack official updates and comprehensive coverage, such as indexer integration.

Question 3

How to connect to Algorand testnet using js-algorand-sdk?

Accepted Answer

Instantiate an `Algodv2` client with testnet endpoints like 'https://testnet-api.algonode.cloud' and a token (often empty for public nodes). Public endpoints and setup guides are on Algorand's developer portal.

Question 4

What are the breaking changes in AlgoSDK v3?

Accepted Answer

Breaking changes include altered API signatures, new class structures, and deprecated functions, detailed in the migration guide. This affects transaction building and client initialization, requiring code updates.

Question 5

Can I use AlgoSDK in a React app?

Accepted Answer

Yes, by including the browser bundle via CDN or installing via npm for build tools. However, client-side key management must be handled securely, and TypeScript compilation may add build complexity.

Question 6

How do I compile TEAL contracts with this SDK?

Accepted Answer

Use `algosdk.compileProgram` to compile TEAL code to bytecode for deployment. This requires access to an algod client with the compile endpoint enabled, typically on a local or remote node.
