Tower

Tower is a stablecoin trading aggregator on Arc that pools liquidity from several decentralised venues into one entry point, ranks routes by net output and merges bridging with swapping into a single execution for cross-chain cases. Routing first generates candidate paths through a model and then filters them by live depth and fees, aiming to find the cheapest combination across fragmented liquidity; the developer interface is open so wallets and payment apps can request quotes without maintaining their own venue lists.

It addresses liquidity fragmentation in a young chain: the same stablecoin pair can differ by tens of basis points across venues, manual comparison is impractical, and splitting orders adds gas and confirmation time. The aggregator automates comparison and order splitting, reducing slippage accumulated across hops, and deducts each venue's fee directly in the quote. On 9 September 2026 the project disclosed its selection for the Arc accelerator programme, which expanded from 8 to 12 teams, and took part in a Demo Day co-hosted by Encode Club and Arc. Its narrative role is the liquidity routing layer for Arc.
