How Foundry works
Foundry is a bonding-curve token launchpad on Robinhood Chain. Launch a token for free, trade it on a transparent on-chain curve, and — once it collects enough ETH — it graduates into a pool whose liquidity is locked forever. Fees favour creators the most while a coin is small.

The bonding curve
Every Foundry coin is a fixed-supply 1,000,000,000 (1B) token, 18 decimals, minted once to its curve contract — no owner, no mint function, no transfer tax. Price is set by a constant product over virtual reserves:
price = (vETH₀ + collected) / (vTokens₀ − sold)
| Parameter | Value |
|---|---|
| Virtual ETH (vETH₀) | 1.2 ETH |
| Virtual tokens (vTokens₀) | 1.073B |
| Sellable on the curve | ~800M tokens |
| Reserved for graduation LP | ~200M tokens |
| Launch FDV (~$3k ETH) | ~$3,600 |
| Graduation threshold | 3.5 ETH collected (~$10.5k in) |
| Graduation FDV analog | ~$45,000–55,000 |
The graduation threshold is fixed per launch at deploy time — it can never be changed on a live curve by anyone, including us.
Fees
- Launch fee: 0. Launching is free.
- Curve trading fee: 1%, taken on every buy and sell into the fee vault. Creator fees accrue from the very first trade.
- After graduation: the 1% pool tier, collected by the FeeLocker for the life of the coin.
Market-cap-scaled creator share
Your cut of the 1% fee is highest while your coin is small (the discovery band) and tapers as it matures — the protocol carries more only once a coin is large. The split is looked up deterministically from the current price (curve state before graduation, pool price after) — no oracle. Whatever the creator does not receive goes to the protocol treasury.
| Market cap (FDV) | Creator share of the 1% | Protocol |
|---|---|---|
| < $100k | 0.95% (95% of the fee) | 0.05% |
| $100k – $300k | 0.80% | 0.20% |
| $300k – $1M | 0.50% | 0.50% |
| $1M – $5M | 0.25% | 0.75% |
| $5M – $20M | 0.10% | 0.90% |
| > $20M | 0.05% | 0.95% |
Creators can claim accrued fees at any time and route them across up to 10 payout wallets by weight. After graduation the pool split defaults to 50/50 creator/protocol on collected liquidity-pool fees, fixed per launch.
Graduation & locked liquidity
When a curve reaches 3.5 ETH collected, anyone can trigger graduation (a small ETH bounty is paid to the caller, so it always happens without trusting a keeper):
- A pool is created on Foundry's own Uniswap-style DEX fork at the 1% tier, and the collected ETH plus the reserved tokens are minted as a full-range position.
- The liquidity-pool NFT is transferred to the FeeLocker, which has no withdraw function — the liquidity is provably locked forever.
- Curve trading is disabled; the token is already freely transferable, so trading continues seamlessly on the DEX.
Unique tickers, forever
Each ticker can only be launched once on Foundry — case-insensitive, permanently. If a symbol has been used, it can never be launched again. This is enforced at the contract/factory level, not just in the interface.
Anti-snipe protection
- For the first 3 blocks after launch, a single transaction can buy at most 1% of supply (10M tokens).
- No buying and selling in the same block on the curve — this blocks bundled snipe-and-dump bots.
These rules are enforced inside the curve's buy/sell functions and cannot be bypassed by bundling calls through a multicall.
Immutability & audits
The novel money-holding code — the curve and the locker — is deliberately small and non-upgradeable. Immutability is the trust model: contracts cannot be changed after deploy, and factories are versioned rather than migrated (a new factory version never affects coins launched under an older one).
