Status: in audit — mainnet paused

The launchpad
that ships the code first,
the token second.

A Solana bonding-curve launcher with a three-way fee split, Meteora DLMM graduation, and a hard 5 SOL per-launch cap in beta. Every line of the on-chain program is public, MIT-licensed, and waiting for its audit before it touches your wallet.

01

Bonding curve, not a lottery

Constant-product x·y = k pricing with token-favorable rounding. Same math as pump.fun; different economics: 1.236B virtual token reserves, 55 SOL graduation target, ceiling on buys, floor on sells.

02

Three-way fee split

Every trade: 33.33% creator · 33.33% DINO buyback · 33.34% treasury. Creation fee 0.02 SOL, graduation fee 1 SOL, both split 50/50 between DINO and treasury. Nothing goes to a hidden admin key.

03

Graduation to Meteora DLMM

When a curve fills, 200M tokens and the vault balance seed a Meteora DLMM pool. LP is held in treasury, not burned — governance-recoverable if a pool needs migration.

04

Capped, on purpose

Beta enforces MAX_REAL_SOL_RESERVES = 5 SOL at the program level. Not a UI check — an on-chain require!. You physically cannot lose more than 5 SOL to a single launch until we lift the cap post-audit.

Roadmap

What ships, in what order.

  1. v0.5 — Beta program

    Complete

    Bonding curve, fee split, graduation, seal-graduation, 5 SOL hardcap. Full end-to-end lifecycle passing on local validator. Source public on GitHub, MIT-licensed.

  2. v0.6 — Independent audit

    In progress

    Sec3 Pro engagement (~1–2 weeks). Findings triaged in the open on GitHub Issues. Program key rotates to a 2-of-3 multisig before any mainnet deployment.

  3. v0.7 — Mainnet beta

    Next

    Deploy to Solana mainnet with the 5 SOL cap still active. Meteora DLMM live. Buyback bot and indexer running. Bug bounty escrow funded.

  4. v1.0 — Cap lifted

    Later

    Threshold raised to 55 SOL (~$42k mcap graduation). Public leaderboard, portfolio, docs site. Referral revenue share for creators.

Security

Assume nothing. Read everything.

5SOL
On-chain per-launch cap

Hardcoded in state/token_launch.rs. Reverts with error 6021 (BetaCapExceeded) if exceeded.

3bugs
Found in self-testing

Stack overflow, curve accounting, vault ownership. All fixed in v0.5 — documented in BONDING_CURVE_DIFF.md.

0.1–10SOL
Bug bounty by severity

Private disclosure via SECURITY.md. Payout scales with severity. Escrow funded before mainnet.
