Kraken Lists SUN and WINkLink’s WIN Tokens, Launches $90,000 Airdrop

Kraken cryptocurrency exchange has officially listed two key tokens from the TRON ecosystem—SUN and WIN—for spot trading. Trading for SUN/USD and SUN/EUR pairs began on April 8, while WIN/USD and WIN/EUR trading pairs were added shortly after. 

$90,000 Airdrop Announced Through Reef Program

To encourage adoption and boost community engagement, a $90,000 airdrop campaign—called the Reef Program—was launched alongside the token listings. The program will distribute SUN and WIN tokens to selected users as part of TRON’s strategy to grow its ecosystem.

This airdrop aims to accelerate TRON’s growth and is designed to attract both retail and institutional investors. However, geographic restrictions may apply, meaning not all users will be eligible to participate.

WINkLink (WIN) is TRON’s first decentralized oracle network. It acts as a bridge between TRON-based smart contracts and external real-world data like market prices or random numbers.

The WIN token (TRC-20) powers the WINkLink ecosystem. It’s used to pay for oracle services, reward node operators, and participate in governance decisions. WINkLink has been central to many of TRON’s latest blockchain innovations, including its Verifiable Random Function (VRF) system.

SUN, on the other hand, is central to TRON’s DeFi ecosystem. It powers Sun.io, a platform that enables token swaps, liquidity mining, and yield farming on TRON’s blockchain. By listing SUN, Kraken enhances SunSwap’s reach with institutional-grade trading infrastructure and security.

WINkLink’s Oracle and VRF Systems Bring Real-World Data to TRON

One of WINkLink’s most advanced features is VRF, which generates secure and decentralized random values needed by blockchain applications such as lotteries, gaming platforms, and DeFi tools. The process starts when a user initiates a request through a consumer contract. This triggers a token transfer to a middleware contract called WinkMi.

Once the transfer is complete, the WinkMid contract sends the request to the VRFV2Wrapper contract. The wrapper then forwards the request to the VRFV2Coordinator. At this point, the coordinator emits a blockchain event called ‘RandomWordsRequested’.

The WINkLink node, which monitors the blockchain for such events, picks up the signal and generates random words. These are then returned to the coordinator through a callback. The coordinator passes the results back to the wrapper, which completes the process by calling the original consumer contract. Finally, the consumer contract confirms the delivery of the random values.
