Trading and the AMM

Every token trades against its own pool inside Tribe.run's Solana program, from the moment it launches. The AMM is native: there is no external exchange, no graduation, and no migration. The pool that opens at launch is the pool forever.

USD trading and pool settlement

The app uses canonical USDC as wallet cash. You enter a dollar amount on a buy; a sell starts in USD and can be switched to the token quantity without changing the tokens selected. Sells pay out USDC. The route crosses between USDC and the pool's SOL leg inside the submitted trade, so the pool itself still prices and accounts in SOL. The quote and slippage protection cover the route you sign; converting the cash boundary to USDC does not change the AMM or its market-cap and fee calculations.

Order sizes have a floor: currently a $5 minimum buy and a $3 minimum sell, on every kind of token. The sell floor is absolute, so a position worth less than it cannot be sold until it is worth more.

Network fees

You do not need SOL to use Tribe.run. Tribe pays the Solana network fee on trades, on withdrawals, and on converting USDC into SOL, and launch costs are charged in USDC. Converting SOL into USDC pays its own network fee from your SOL balance, and the rent deposit for a withdrawal recipient's brand-new token account also comes from your balance.

The pool

The pool is a constant-product AMM seeded with 35 SOL of virtual liquidity against nearly the full 1 billion token supply. Virtual liquidity gives the market depth from the first trade and can never be withdrawn.

The last 2,500,000 tokens of the supply, worth about 0.08 SOL at launch, can never be sold back to the pool.

Price and market cap

The pool sets the price. A buy pulls tokens out and adds SOL, so the price rises; a sell does the opposite. The bigger the trade relative to the pool's depth, the more the price moves.

A token's market cap is the current price times the 1 billion token supply, quoted in SOL. Market cap drives the fee schedule and how quickly buying opens beyond the app.

Launch protection

A fresh launch is the easiest target on a DEX: the first buyer gets the best price the token will ever offer. Tribe.run counters snipers in three ways.

First, the creator can attach a first buy that is placed right after the token goes live.

Second, for the first 60 seconds after launch every buy pays a dynamic anti-sniping fee. It starts at 99% of the trade and decays linearly down to the token's normal fee rate as the window closes. The full anti-sniping fee is paid to the token's creator at trade time. Sells never pay it, and the creator's own buys are exempt.

Third, a new token can only be bought through Tribe.run at first. Buys open to any Solana wallet directly on the program once the token's market cap reaches 420 SOL or the token is 24 hours old, whichever comes first. Once open, buying stays open even if the market cap later falls. Selling is open to everyone from the first second.

Liquidity providers

Anyone can add real liquidity on top as a liquidity provider (LP). LP positions are NFTs, start from 0.01 SOL, and lock for 48 hours after every deposit.

LPs earn up to 0.20% of every trade. The LP rate scales with the share of pool liquidity that real LPs provide, and fees accrue to your position until you claim them.
