The contract

One file, contracts/src/Flock.sol, Solidity 0.8.26. No owner, no admin, no proxy, no fee of ours. The only external dependencies are the Pons factory (address fixed at deployment) and the curve it creates.

Constants

State

struct Info {
  address creator; State state;      // Open, Launched, Cancelled
  uint64 deadline; uint96 minTotal; uint96 size; uint96 maxPerWallet;
  uint128 total; uint128 used; uint128 reserve;
  uint256 launchConfigId; uint256 minTokensPerEth;
  bytes32 paramsHash; address token; address curve; uint256 tokensOut; uint128 reserveLeft;
}
mapping(uint256 => Info) public flocks;
mapping(uint256 => mapping(address => uint256)) public deposits;
uint256 public count;

Functions

What launch does, in order

1. checks the state, the deadline, the grace, the minimum and the params hash
2. reads the Pons launch fee and checks the reserve covers it
3. computes used, sets the state to Launched before any external call
4. calls factory.launchToken with itself as snipe-tax exemption
5. calls curve.buy(used, minOut, this)
6. reads its own balance of the new token and checks it against the floor (PriceFloor)
7. stores the token, the curve and the tokens bought

Events

Opened(uint256 indexed id, address indexed creator, bytes32 paramsHash, Terms terms, bytes encodedParams)
Joined(id, who, amount, total)        Left(id, who, amount, total)
Launched(id, token, curve, total, used, tokensOut)
Claimed(id, who, tokens, refund)      Refunded(id, who, amount)      Cancelled(id)
