Decentralized advertising platform Alkimi has partnered with the Sui blockchain to move its entire digital ad supply chain onchain, signaling a major shift in how advertising is executed, verified, and monetized in the Web3 era.
The partnership brings together Alkimi’s decentralized ad infrastructure and Sui’s high-performance technology stack, including the Sui blockchain, Walrus, Nautilus, and Seal. The collaboration is already live, with major brands such as AWS, TikTok, Currys, and Polestar actively participating on Alkimi’s onchain ad network.

The initiative aims to eliminate opaque intermediaries in digital advertising by using blockchain to ensure transparency, verifiability, and faster settlements. Sui acts as the coordination layer for transactions between advertisers and publishers, while Walrus records ad delivery data onchain at scale—currently exceeding 25 million impressions daily.
Nautilus further strengthens the system by running real-time validation and financial reconciliation through trusted execution environments (TEEs). This ensures that advertisers pay only for verified impressions, and publishers are compensated accurately and quickly. Seal, the final layer, encrypts and decentralizes sensitive data, removing the need for centralized servers and protecting client confidentiality.
“Alkimi is fixing a broken digital and advertising ecosystem by bringing it onchain,” said Christian Thompson, Managing Director at Sui Foundation. “We’re proud to be the network enabling this transformation.”
Alkimi CEO Ben Putley emphasized that the goal is not to replicate legacy ad systems on blockchain but to redesign them entirely for speed, fairness, and efficiency.
With full transparency into ad spend, faster payment cycles, and a significant reduction in fees, the partnership marks a critical moment for the commercialization of blockchain technology in real-world industries. It also sets the stage for new monetization models, including data licensing and the rise of AdFi.
Meanwhile, Bluefin, the leading decentralized exchange (DEX) by trading volume on the Sui blockchain, has launched Bluefin7K, a Sui-native aggregator designed to provide users with the best trading rates and access to deep liquidity. By routing trades across multiple DEXs within the Sui ecosystem, Bluefin7K continuously identifies the most favourable pricing and liquidity sources in real-time.
