Public-sale distributor (tokenomics §2)#17
Merged
Conversation
Fixed-price sale of the 15% public allocation. Immutable terms — no owner, no upgrade path, all actions (buy/finalize/claim/refund) permissionless. - Buyers pay a stablecoin at a fixed price for $CSIG during [start, end], up to a hard cap and per-wallet cap; the contract must hold >= hardCap CSIG. - finalize() (after end, or early on hard cap): soft cap met -> proceeds to treasury, unsold CSIG burned to 0xdead (§2), buyers claim(). Soft cap missed -> buyers refund() their stablecoin and the allocation returns to treasury. - Claim-based delivery so a failed sale refunds cleanly; SafeERC20 + nonReentrant + CEI throughout; ceil-rounded pricing. CountersigPublicSale.t.sol: 17 tests (success/burn/claim, failure/refund, caps, funding, early finalize, guards). DeployPublicSale.s.sol deploys the immutable sale. Full suite 149.

The last token-side launch contract: sells the 15% / 150M public allocation.

DeployPublicSale.s.soldeploys the immutable sale. Full suite 149, slither clean, deploy dry-run clean.Note: this is the plain-fixed-price design. If you want vested delivery of purchased tokens (my earlier recommendation to soften day-1 float/optics), that's a deliberate follow-on — say so and I'll layer it in.
