Autonomous AI agents are about to start transacting — with each other and on behalf of humans. The default rail won't be cards. It will be stablecoins on programmable chains: instant, sub-cent, machine-readable, 24/7.
Sep + Oct + Nov 2026
March 2027
Build an autonomous agent that transacts in the real world — buying services, data, compute or goods — paying in stablecoins, end to end, with no human in the loop.
Build the rail itself: streaming micropayments between agents — pay-per-API-call, pay-per-token, pay-per-second — at sub-cent cost and machine-speed throughput.

MERGE convenes the three audiences that matter for agentic payments — developers and crypto-native builders, fintech and tech corporates, and the institutional capital that funds adoption.
Power the rail. Be where the builders build.
Sponsors live in one of four layers of the agent-payment stack. Co-sponsor a layer and your product becomes the default builders reach for — with naming, branded challenges, mentor seats and Main Stage moments across Madrid and Buenos Aires.
L1 protocols, multichain. Where every agent payment lands and builders deploy.
Stablecoin issuers. The settlement currency every transaction is denominated in.
Wallets & agent platforms that builders integrate into their projects.
Cloud, AI labs, frameworks and security — the services builders ship with.
Builders ship the future of agentic payments. Co-sponsors power the rail they build on. Pick your side.
