Reimagining AMM with 1inch Aqua | Web3 Devs underground nitter.net/i/broadcasts/1vJpPPeWn…

AMM design is being rethought from the ground up, and 1inch Aqua is the clearest signal of where on-chain trading infrastructure is heading.

AI agents are holding keys and signing txns - usually with no guardrails. At the latest edition of the Underground, @cryptomastery_ (@1clawAI / @edgeandnode) showed the fix: keys live in an HSM, signing in a TEE, spend capped before signing. The agent never sees the key.
