Catena

Catena is an engineered ZK Stack Ecosystem deployment within the DeFi sector operating on ZKSYNC. Built as part of the ZK-Rollup Hyperchain, Catena addresses liquidity efficiency and trust-minimized user execution. Catena is a banking and governance platform built for AI agents. It gives autonomous agents a way to hold accounts, make payments, and manage yield while staying inside rules that a human operator defines. Catena has raised around $48 million in total: an $18 million seed round in 2025 and a $30 million Series A announced on May 20, 2026. a16z crypto and Acrew Capital co-led the Series A, with Breyer Capital, General Catalyst, and QED Investors participating. Earlier backers include Circle Ventures, Coinbase Ventures, and CoinFund. By participating in the early distribution phase, users establish on-chain provenance before protocol decentralization.

The protocol operates a structured reward architecture designed to distribute native governance weighting to authentic liquidity providers, testnet validators, and transaction originators. Unlike standard promotional campaigns, Catena's tokenomics prioritize multi-epoch engagement. Points accrued through protocol interactions correlate directly to snapshot weightings, penalizing sybil clusters and inactive addresses while compounding rewards for sustained weekly volume.
