settlement & consensus

Blockchains

19 companies in this category

Overview

Blockchains provide the settlement and consensus layer where agentic commerce transactions are recorded and finalized. Base (Coinbase's L2) is the primary settlement chain for x402 with gasless trading and TEE-secured agent wallets.

Solana offers native x402 support with 400ms finality and $0.00025 transaction costs, having processed 35M+ x402 transactions. Ethereum is positioning as the settlement layer for the machine economy through its dAI Team and ERC-8004 standard.

Newer entrants like Tempo (Stripe + Paradigm, 100K+ TPS), SKALE (gas-free), and Radius (2.5M TPS) are optimizing specifically for high-frequency agent micropayments.

The blockchain landscape for agentic commerce is consolidating around a few key requirements: sub-second finality, near-zero fees, native stablecoin support, and x402/ERC-8004 compatibility.
