How BARN works

The 2021 yield-farming playbook, rebuilt on Solana without the rugs.

1. Launch

Pick a name, a ticker, a logo and your links. Choose how much of the supply goes to farm rewards (5–80%) and for how long.
Your token is minted with a fixed supply of 1,000,000,000 and the mint authority is revoked in the same transaction: nobody can mint more.
Three pools open on Meteora DAMM v2: TOKEN/SOL, TOKEN/USDC and TOKEN/$BARN. They are single-sided: you put no SOL. The protocol sets the starting price so the three pools start at the same dollar price.
The initial liquidity is locked forever. You can never pull it.

Every buy and sell pays a fixed 2.5% fee. During the first 60 seconds of a pool the fee starts at 50% and drops every second to 2.5%, so bots that snipe the opening pay for it.
Of the 2.5%, Meteora keeps 0.5%. The rest goes 50% to the creator and 50% to the protocol; half of the protocol's part buys back and burns $BARN.

Add liquidity to any of the three pools and put the position in the farm. You can zap with a single coin: half buys the token and both halves become your position.
While your position is in the farm, you earn the token from the reward reserve, every second, proportionally to your share of the farm.
The trading fees of farm positions go to the creator and the protocol, not to the farmer. That is the deal: you farm the token, the pool's fees pay the creator and burn $BARN.
Withdraw any time: you get your rewards and your LP position back.

APR = rewards per year × token price ÷ value in the farm. Right after a launch there is very little in the farm, so the APR is huge. As more liquidity comes in, it goes down.
When nobody is farming yet, we show the APR the first $1,000 would get.

Rewards are paid in the token itself. If farmers sell their rewards, the price falls, and the APR in dollars falls with it.
Each pool starts single-sided at its launch price, which acts as a floor: a pool cannot buy back more tokens than were bought from it. When a pool reaches its floor, selling there fails until someone buys; you can still sell in the other two pools.
Providing liquidity has impermanent loss: if the price moves, your position ends with more of the asset that fell.
Farm positions do not earn trading fees; they earn only the farmed token.
Anyone can launch a token. A token being on BARN is not an endorsement. Do your own research.
Smart contracts can have bugs. BARN uses Meteora's audited pools, and its own program is audited before mainnet, but no audit removes all risk.
