Agentic Index
Causa Prima vs Circuit And Chisel (2026)
Two takes on agents transacting with each other rather than with people, at 8 and 4 of 14.
Causa Prima is an agent to agent network for B2B finance where buyer and supplier agents settle invoices, disputes and payment terms directly in real time, aiming to retire fixed net payment terms entirely. Circuit and Chisel is building ATXP, an open web wide protocol for agents to discover, negotiate and settle instant low cost micropayments, connecting agentic commerce, stablecoins and payments into one rail. Causa Prima solves a specific expensive problem in accounts payable; Circuit and Chisel is building general infrastructure. Both are pre commercial and should be evaluated as bets rather than purchases.
Choose Causa Prima if
- Documented coverage is materially broader and the use case is concrete and expensive today.
- Net payment terms and dispute cycles are a real cost you can quantify.
- You want a network with counterparties, not a protocol you still have to adopt.
Choose Circuit And Chisel if
- General purpose micropayments beyond B2B invoicing is the scope you care about.
- An open protocol rather than a network avoids depending on who else joined.
- Stablecoin settlement is part of how you expect agent commerce to work.
