THE FIELD
GUIDE

Every verified FortMint coin is paired with one public Fortnite island. A share of creator fees flows into a coin-specific fund that can pay only for tournaments, updates, giveaways and promotion.

1. Find a public island code.
2. Add the coin name, ticker and art.
3. Set the fee share and allocations to exactly 100%.
4. Connect a wallet, review and sign.

Codes are three groups of four digits. FortMint accepts digits, dashed codes, or URLs containing a code.

The launch prepares pump.fun's create, fee-sharing configuration and immutable shareholder instructions. All shares use integer basis points and must total 10,000.

launcherBps = 10_000 - fundBps
fundBps + launcherBps === 10_000

New mints receive a random, isolated System Program fund account. Its per-market key is encrypted at rest with a production-only secret; one market key cannot derive any other market key. Legacy launcher-controlled seed accounts remain supported read-only.

Collections are permissionless: any wallet can pay the network fee, while pump.fun distributes the configured share to the fund. Requests are rate-limited, fingerprinted and idempotent, and confirmed signatures are written to the ledger.

Only the launch authority can approve payouts. Requests include nonce, expiry, recipient, amount and purpose. The server enforces the budget and exact transaction bytes. The isolated fund signs only the transfer while the launcher approves the transaction in Phantom.

purposePool = collected × (10_000 - creatorShareBps) / 10_000
available = floor(purposePool × purposeBps / 10_000) - spent

GET /api/islands/{code} returns real public Epic Data API metrics or a clear upstream error.

POST /api/launch/prepare validates the island and metadata, uploads metadata, builds transactions and stores their fingerprints. Signed bytes are accepted only by the confirm endpoint.

GET /api/coins/{mint}/fund returns persisted balances, allocations and transaction ledger entries.

GET /api/creators/{code} exposes public, ledger-derived balances. Epic sign-in binds a creator code to a Phantom payout wallet. New automatic matches wait 24 hours, and each request atomically reserves and pays up to five coin funds. Submitted signatures remain reserved until reconciliation so a timeout cannot create a double claim.

FortMint is independent from Epic Games and pump.fun. Tokens are speculative and blockchain transactions are irreversible.
