Read From Contract

For read-only contract calls that don't modify state.

Process Composition

This pipeline chains the following processes:

1. P_BuildTransaction — Creates the transaction

2. P_SimulateTransaction — Simulates and extracts return value

Usage

import { PIPE_ReadFromContract, NetworkConfig } from "@colibri/core";
import { Operation } from "stellar-sdk";

const network = NetworkConfig.TestNet();

const pipeline = PIPE_ReadFromContract.create({
  networkConfig: network,
});

const operation = Operation.invokeContractFunction({
  contract: "CABC...",
  function: "balance",
  args: [
    /* ScVal arguments */
  ],
});

const returnValue = await pipeline.run({
  operations: [operation],
});

console.log("Balance:", returnValue);

When to Use

Use this pipeline when:

• Reading contract state (balances, metadata, etc.)

• No transaction submission is needed

• You only need the simulated return value
