Economics Basics

8 examples to get you started with Economics on Agave 4.1.1 - 5 basic and 3 intermediate.

Prerequisites

solana config set --url devnet
npm install @solana/kit@7.0.0

Basic Examples

1. Inspect via RPC

import { createSolanaRpc } from "@solana/kit";
const rpc = createSolanaRpc("https://api.devnet.solana.com");
const slot = await rpc.getSlot().send();
console.log(slot);

• Confirms RPC connectivity and cluster reachability
• Use devnet before mainnet-beta integration

2. CLI Verification

solana slot
solana balance

• Solana CLI 3.0.10 shares config with Anchor provider
• Match solana config get URL with client RPC

3. Read On-Chain Logs

solana confirm -v <SIGNATURE>

• Logs expose program msg! output and CU consumed
• Decode errors before retrying transactions

4. Simulate First

const sim = await rpc.simulateTransaction(encodedTx, { sigVerify: false }).send();
console.log(sim.value.err, sim.value.logs);

• Preflight catches most failures without landing fees
• Essential during Anchor 0.32.1 program development

5. Anchor Program Hook

use anchor_lang::prelude::*;
#[program]
pub mod example {
    use super::*;
    pub fn touch(_ctx: Context<Touch>) -> Result<()> { Ok(()) }
}
#[derive(Accounts)]
pub struct Touch {}

• Programs execute in Sealevel with explicit account lists
• Stateless logic + separate data accounts

Intermediate Examples

6. Build Version 0 Transaction

import { createTransactionMessage, pipe } from "@solana/kit";
const msg = pipe(createTransactionMessage({ version: 0 }), (m) => m);

• v0 transactions support address lookup tables
• Prefer @solana/kit 7.0.0 transaction builders

7. Set Compute Budget

# Client adds ComputeBudgetProgram instructions for CU limit and price

• Request enough CU under load
• Priority fees use microlamports per CU

8. Test Locally

npx surfpool@0.12.0 run anchor test

• Surfpool provides Agave-compatible local validation
• LiteSVM 0.6.x suits lightweight unit tests
