JetForge — on-chain program
The Solana program behind JetForge, a fair-launch token launchpad:
launch an SPL token in one transaction, trade it on a bonding curve, and graduate it to
Raydium automatically.
This repository publishes the program's source so anyone can read exactly what the
deployed program does. It contains only the on-chain program; the website, backend, API and MCP server
are not part of it.
How it works
Launch. create_token creates the mint, its Metaplex metadata and its bonding curve in
one transaction. Mint authority and freeze authority are revoked and the metadata is
immutable, so supply can never grow, holders can never be frozen, and the name, symbol and
image can never change. There is no presale and no free team allocation: every token,
including any the creator buys, comes from the bonding curve at the same price as everyone
else's. (The jetforge.io launch form lets the creator add a first buy of up to 5% of the
supply in the same transaction; that limit is set by the website, not by the program.)
Supply. 1,000,000,000 tokens (6 decimals): 700,000,000 are sold on the bonding curve,
300,000,000 are reserved for the Raydium pool.
Bonding curve. Constant product (x · y = k) over virtual reserves that start at
30 SOL and 947,058,823.529412 tokens. Everyone buys and sells against the same formula.
Fees. 1% on every buy and sell, split on-chain in the same instruction:
| Recipient | Share |
|---|
Token creator (per-token vault, withdrawable any time via withdraw_creator_fees) | 40% |
| Platform treasury | 40% |
| Per-token buyback-and-burn vault | 20% |
Buyback and burn. execute_buyback is permissionless once a token's buyback vault holds
0.1 SOL: it buys the token back from the curve and burns it. Keeping each burn small makes
it unprofitable to sandwich.
Graduation. When the curve has raised 85 SOL, graduate_to_raydium migrates the token
to a Raydium CPMM pool in a single transaction:
- 90% of the raised SOL (plus any leftover buyback SOL) and the matching tokens seed the
pool, sized so it opens at the curve's final price; excess reserve tokens are burned;
- 5% of the raised SOL goes to the creator and 5% to the treasury;
- the LP tokens are burned in the same transaction, so the liquidity is locked forever;
- the pool address is a program-derived address, so nobody can front-run the canonical pool.
Graduation funds never pass through a wallet with a private key: the transaction either
completes entirely or does nothing.
graduate is a legacy fallback, callable only by the multisig above.
Instructions
| Instruction | Who can call it |
|---|
create_token | anyone |
buy / sell | anyone |
graduate_to_raydium | anyone, once the curve is complete |
execute_buyback | anyone, once the buyback vault holds ≥ 0.1 SOL |
withdraw_creator_fees | the token's creator |
graduate (legacy fallback) | the 2-of-3 multisig only |
For bots and AI agents
Bots and AI agents can trade JetForge tokens with no API key. No endpoint or tool can move
funds: trades come back as unsigned transactions, which the caller's own wallet signs and
broadcasts. JetForge never receives private keys.

| Tool | What it does |
|---|
list_markets | Active tokens with live price, reserves and graduation progress |
get_quote | Prices a buy or sell from the live bonding curve |
prepare_trade | Builds an unsigned buy or sell transaction |
get_wallet | Returns a wallet's SOL and token balances |
REST API: https://jetforge.io/api/v1, limited to 300 requests per minute per IP. See the
API docs and examples and the
OpenAPI spec.
Never give a private key to an MCP server, including this one. Limit how much an agent's
wallet holds, and check each transaction before it's signed.
Building
The mainnet program is built with no cargo features:
cargo-build-sbf --manifest-path programs/token-launch/Cargo.toml
Toolchain used for the deployed build: Solana CLI / cargo-build-sbf 3.1.11 (Anza), stable Rust.
Cargo features select test builds and change the program ID, treasury and Raydium program:
| Feature | Use |
|---|
| (none) | mainnet |
devnet | devnet build (devnet program ID, treasury and Raydium CPMM) |
e2e | local end-to-end tests only |
devnet-low-threshold | devnet only: graduation at 3 SOL (refuses to compile without devnet) |

Security
Please report vulnerabilities privately; see SECURITY.md.
The program has not been formally audited by a third party. Token trading is risky:
only trade what you can afford to lose.
