Open Loot

01Description

Web3 gaming distribution platform from Big Time Studios: custody, fiat + crypto checkout, KYC/AML, an integrated NFT marketplace, a PC game launcher, and a developer REST API. The native $OL token (live since Nov 2024) powers fee discounts and the upcoming OL Chain. Open Loot abstracts wallets and gas behind player accounts so games can mint, distribute, and trade in-game items without bespoke Web3 infrastructure.

05Prompt snippet
Open Loot has no first-party JS SDK — integrate via the REST API at `https://api.openloot.com` (see developers.openloot.com). From your game backend authenticate with `Authorization: Bearer $OPENLOOT_API_KEY` and call endpoints like `GET /v1/users/{id}/inventory`, `POST /v1/items/grant` (distribute items to a player), `POST /v1/marketplace/list` (create listings), and the launcher entitlement endpoints to verify ownership at game start. For desktop titles, integrate the Open Loot Launcher SDK so the launcher passes a signed session token into your game on boot. Player wallets are custodial (Open Loot Vault) — withdrawals to self-custody go through an explicit cross-chain redemption flow.
06Gotchas
  • Open Loot wallets are fully custodial via the Vault; players don't hold keys, and asset withdrawal to a self-custody wallet is a deliberate UX (and sometimes throttled / KYC-gated) rather than the default — design for an in-platform economy.
  • Listing on the Open Loot marketplace is gated by Big Time Studios — you must apply and be approved as a partner studio, not just hit the API; integration timelines run weeks, not hours.
  • OL Chain (the dedicated gas + utility chain) is rolling out alongside the legacy Ethereum/Polygon contracts; collection canonical chain may shift, so resolve contract addresses from the Open Loot API rather than hardcoding.
  • Peer-to-peer transfers happen inside Open Loot's ledger (off-chain-ish) until withdrawal — secondary sale royalties and bans are enforced platform-side, and bypassing the platform with on-chain transfers is restricted by the Vault model.
  • Gas is paid by the platform (not the player) for in-platform actions, but withdrawals incur on-chain fees in ETH/MATIC/$OL depending on destination chain — surface this fee clearly before users initiate a withdrawal.
  • The Launcher integration for PC games requires a code-signed Windows binary and an entitlement check on boot; running the dev SDK from an unsigned build will fail on user machines but not on local dev VMs.
