NFTmall X Chainlink

We are excited to announce the integration of Chainlink Verifiable Random Function (VRF) into the NFTmall ecosystem on Ethereum and Binance Smart Chain (BSC) and soon Avalanche main nets. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to help mint genesis NFTs with provably random traits and help ensure that each user has a chance to receive the rarest items from blind boxes.

The integration of Chainlink VRF leads to a more exciting, transparent, and fraud-proof user experience as users have on-chain proof that rare NFT traits and the most collectible items from blind boxes were generated in an unbiased manner, meaning each user has an equal chance to receive the most collectible NFTs and items.

NFTmall will be using Chainlink VRF for provable randomness in our upcoming Founder NFT series “Angry Eaglets” and also in all of our upcoming NFT & GameFi-related products.

Instead of using centralised price feed, NFTmall will use Chainlinks tamper proof 100% uptime on-chain price feed for pairs like AVAX/USD, BNB/USD, ETH/USD


NFTmall is a multi-standard, multi-chain, Physically redeemable NFT platform where talented artists (creators) produce and display their skills while earning incentives without third-party interference. It also allows collectors and affiliates to earn while having fun. NFTmall is also the world’s first physically-redeemable NFT marketplace where users can redeem various NFTs for their physical, real-world equivalents and get them delivered to their doorsteps! Options range from Canvas, Framed Canvas, Digital Frames, and more. The redemption feature is soon to go LIVE as well, bringing new functionality to NFTs worldwide. NFTmall is not just a marketplace but a community where there is a governance token known as GEM that helps empower creativity and a community-focused approach to NFT production, yielding, and staking.

Why NFTmall Choose Chainlink VRF?

In order to help ensure our NFT mints and blind boxes are tamper-proof and unbiased for all participants, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof about the integrity of the process.

After reviewing various solutions, we selected Chainlink VRF because it’s based on cutting-edge academic research, supported by a time-tested oracle network, and secured through the generation and on-chain verification of cryptographic proofs that prove the integrity of each random number supplied to smart contracts.

Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. The NFTmall smart contract will only accept the random number input if it has valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This provides our users with automated and verifiable assurances directly on-chain that our genesis NFTs and blind boxes are provably random and were not tampered with by the oracle, outside entities, or the NFTmall team.

“Chainlink VRF is the game-changing technology we needed to bring NFTmall to the next level,” stated MD Rakib Ahamed, Founder and CEO of NFTmall. “We look forward to further integrating Chainlink decentralized services to enhance the functionality of our NFT marketplace.”
