!pump Pump.fun Anchor SDK


An unofficial Pump.fun Solana program SDK written in Rust and Anchor.

Features

- Typescript Anchor IDL for building pump transactions with code completion and minimum account inputs required.
- Rust API for building pump transactions with structured accounts and arguments.
- Rust CPI methods for building your own on-chain program on top of pump.

Usage

$3

Install npm package pump-anchor-idl:

``bash
npm install --save pump-anchor-idl
`

#### Example

`typescript
import { Program } from "@coral-xyz/anchor";
import idl from "pump-anchor-idl";

const pumpProgram = new Program(idl, anchorProvider);

const FEE_RECIPIENT_ADDRESS = new PublicKey(
"CebN5WGQ4jvEPvsVU4EoHEpgzq1VV7AbicfhtW4xC9iM"
);

async function pumpBuy(wallet: Keypair, mint: PublicKey, amount: BN, maxSolCost: BN) {
const tokenAccount = getAssociatedTokenAddressSync(mint, wallet.publicKey, true);
const createTokenAccountInstruction = createAssociatedTokenAccountInstruction(
wallet.publicKey,
tokenAccount,
wallet.publicKey,
mint,
);

return await pumpProgram.methods
.buy(amount, maxSolCost)
.accounts({
mint,
associatedUser: tokenAccount,
feeRecipient: FEE_RECIPIENT_ADDRESS,
program: pumpProgram.programId,
})
.preInstructions([createTokenAccountInstruction])
.signers([wallet])
.rpc();
}
`

$3

Add dependencies in Cargo.toml:

`toml
[dependencies]
pump = { git = "https://github.com/s6nqou/pump-anchor", package = "pump", features = ["cpi"] }

for on-chain program

anchor-lang = { version = "0.30.1" }

for client

anchor-client = { version = "0.30.1" }
`

#### Example: Cross-program invocations (CPI)

`rust
pub fn custom_pump_buy(ctx: Context, amount: u64, max_sol_cost: u64) -> Result<()> {
pump::cpi::buy(
CpiContext::new(
ctx.accounts.pump_program.to_account_info(),
pump::cpi::accounts::Buy {
global: ctx.accounts.global.to_account_info(),
fee_recipient: ctx.accounts.fee_recipient.to_account_info(),
mint: ctx.accounts.mint.to_account_info(),
bonding_curve: ctx.accounts.bonding_curve.to_account_info(),
associated_bonding_curve: ctx.accounts.associated_bonding_curve.to_account_info(),
associated_user: ctx.accounts.associated_user.to_account_info(),
user: ctx.accounts.user.to_account_info(),
system_program: ctx.accounts.system_program.to_account_info(),
token_program: ctx.accounts.token_program.to_account_info(),
rent: ctx.accounts.rent.to_account_info(),
event_authority: ctx.accounts.event_authority.to_account_info(),
program: ctx.accounts.pump_program.to_account_info(),
},
),
amount,
max_sol_cost,
)?;
}
`
