A creator's identity is a hash, not an account:

routeKey = keccak256(abi.encodePacked(platform, handle))

Handles are lowercased and stripped of their prefix first, so @Vitalik and vitalik resolve to the same route. The contract exposes computeRouteKey() so you can verify any route yourself.

Applied identically in the browser, the API and the contract. Any difference would produce a route nobody could ever claim.

Claiming is gated by an EIP-712 signature over this struct, signed by the attestor key after Privy confirms the logged-in account owns the handle:

Claim {
  bytes32 routeKey
  address wallet
  uint256 nonce
  uint256 deadline
}

Domain is PopsFeeRouter v1, bound to the chain ID and the FeeRouter address. Nonces are single-use and the deadline is ten minutes, so an attestation can't be replayed or banked for later.

The UI is a thin wrapper over one adapter call. Compute the routeKey, then:

LaunchAdapter.launch(
  string  name,
  string  symbol,
  bytes32 routeKey,
  uint16  creatorCutBps,   // 0–9000
  bytes   tokenData,       // (description, link, image, extra)
  bytes32 salt
)

It emits CoinLaunched with the token address. Anything launched directly against the adapter is picked up by the indexer, so it shows up here without touching this site's API.

Authenticated routes expect Authorization: Bearer <privy access token>.

Logos are square-cropped to 400px WebP in the browser, capped at 512 KB, and stored server-side. The resulting URL is written into the token's on-chain metadata as well as the index, so it travels with the coin rather than living only here. PNG, JPEG, WebP and GIF are accepted; animated GIFs are kept as-is.
