Balancer
Programmable-liquidity AMM protocol included as a Base MCP skill for agent-driven swaps and liquidity actions.
Overview
Balancer is a programmable-liquidity AMM protocol supporting custom pool weightings and composable pool types across several EVM chains. It was included as a launch-day plugin in the now-archived Base MCP (Coinbase archived the repo in May 2026); agents today integrate through Balancer's own contracts and SDK for swap routing and liquidity provisioning. In November 2025, an exploit in Balancer's V2 vault resulted in roughly $128M in losses; the protocol continues operating.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
