INJ is the native token of Injective, a layer 1 blockchain built for finance and one of the largest on-chain derivatives ecosystems in decentralized finance (DeFi). The chain runs an on-chain order book instead of an automated market maker, and 60% of the exchange fees it collects go into a weekly burn auction where the winning bid is paid in INJ and burned.

At Polkastarter, INJ holders can shop for physical collectibles, including rare trading cards, sealed products, and video games. New users can claim a free mystery pack when signing up.

One of the more useful options is travel. CoinBooking lets you use INJ to book hotels and flights at prices up to 30% lower than Booking.com. New users can claim $25 off their first booking.

1. Buy Physical Collectibles With INJ on Polkastarter

Through Polkastarter, INJ holders can put their crypto toward something they can physically own. The marketplace offers authenticated trading cards, sealed products, physical video games, and other premium collectibles. Each purchase comes with on-chain proof of ownership.

Physical items stay in secure custody while ownership changes hands digitally. Holders can have their collectibles shipped to them later or sell them back through Polkastarter.

INJ isn't currently supported as a direct payment method, so holders need to swap it for a supported cryptocurrency first. From there, they can browse the available Lootboxes and collectibles, with details like contents, values, and odds shown before purchase.

New users can also claim a free mystery pack after they sign up. Browse Polkastarter's collectibles marketplace to see what's currently available.

2. Book Discounted Hotels and Flights With INJ on CoinBooking

Instead of leaving INJ sitting in your wallet, you can use it to book travel on CoinBooking, a leading Dubai-licensed crypto travel broker. You can book your next trip through CoinBooking at prices up to 30% lower than Booking.com. CoinBooking gives INJ holders access to more than 2 million hotels and flights across 190+ countries.

You can pay for bookings directly with INJ without converting it to fiat first, helping you avoid the extra fees and markups often associated with crypto-focused travel platforms. CoinBooking also supports 200+ other cryptocurrencies, along with Visa, Mastercard, Apple Pay, and Google Pay.

CoinBooking is also offering new users $25 off their first booking.

3. Use INJ Across the Injective Ecosystem

INJ has several roles inside Injective. It pays gas on the chain, secures the network through proof-of-stake staking, and gives holders a vote on governance proposals.

The token is also the only bidding asset in Injective's burn auction. Every week, 60% of the exchange fees collected on the protocol go into a basket that users bid on with INJ, and the winning bid is burned.

That deflation has been tightened more than once. INJ 3.0 tied issuance to the share of INJ staked on-chain and raised the deflation rate by 400%, and proposal IIP-617 later passed with 99.9% approval to double it again.

Monthly Community BuyBack rounds work differently: participants commit INJ, receive a pro rata share of ecosystem revenue in USDT and other tokens, and the committed INJ is burned on-chain. The chain's native EVM layer went live on November 11, 2025, with more than 30 projects launching on it on day one, next to the Helix exchange and the rest of the MultiVM ecosystem.

4. Spend INJ With a Crypto Card

INJ can be used for everyday purchases through crypto payment cards. Depending on the provider, you can use a card to pay online, shop anywhere Visa or Mastercard is accepted, or make mobile payments through Apple Pay and Google Pay.

The options differ by region. RedotPay is available across Europe, Asia, Latin America, and the Middle East, but not to US residents. KAST offers both virtual and physical cards for Solana users, while Ether.fi combines self-custody with cashback on eligible purchases.

To get started, choose a provider available in your country, fund the account with INJ, and order a card. Check each provider's fees, features, and availability before signing up.

6. Access Early-Stage Token Sales Through CoinTerminal

INJ holders can use their tokens to take part in early-stage crypto projects through CoinTerminal. The launchpad gives users access to token sales before they are listed on exchanges, with contributions starting at $100 and no staking requirements.

Because INJ isn't accepted directly for contributions, holders first need to swap it for USDT. Once the USDT is in their wallet, they can use it to participate in an eligible sale. CoinTerminal also offers a full-refund guarantee on its launches, giving users an added layer of protection when investing in early-stage projects.
