Transaction Management API

Interacting with on-chain programs typically involves constructing transactions with the correct instructions, signers, and account addresses. Nyvo’s internal API simplifies this through a transaction builder layer. In the front-end code generated by Nyvo, instead of manually using new Transaction().add(...) with raw TransactionInstruction, developers find higher-level functions. For example, if using Nyvo’s SDK in the frontend, you might see calls like NyvoApi.marketplace.createListing(tokenMint, price) or NyvoApi.staking.stake(amount). These functions internally know which program ID to target and how to format the instruction data. They likely utilize an IDL or schema to encode instruction arguments and to specify which accounts need to be passed in (for instance, the staking function will automatically include the PDA of the staking pool and the user’s token account).

This abstraction extends to error handling and simulation: Nyvo’s transaction API could integrate Solana’s simulateTransaction under the hood to predict whether an action will succeed. For instance, calling NyvoApi.launchpad.buy(amount) might first simulate the purchase to ensure you’re not exceeding the available token supply or hitting any program constraints; if simulation is successful, it then sends the real transaction for signing. The developer can enable verbose mode to see logs from simulation (which include the program’s msg! outputs and any error codes). Using simulation not only helps catch errors early, but also aids in gas cost prediction: by examining the simulation result, Nyvo can estimate how many compute units the transaction consumedsolana.com. This allows it to adjust the compute budget if necessary (e.g., if the default 200k compute units per instruction might be exceeded, Nyvo’s API can automatically attach a SetComputeUnitLimit instruction to request more, up to the 1.4M maximumsolana.com).

Nyvo also manages transaction batching when a single user action necessitates multiple on-chain instructions. Suppose a user triggers an action that involves multiple programs (maybe buying from a marketplace and immediately staking the purchased item). Normally this would be two separate transactions, but Nyvo’s transaction manager can bundle them into one transaction with two instructions, so the user signs once and execution is atomic. The API might expose a way to compose such multi-step workflows easily, without the developer manually copying account inputs between instructions.
