Frax AMO Keeper Operational Runbook

The Frax AMO Keeper Operational Runbook defines the procedures and parameters for off-chain keeper bots that execute Algorithmic Market Operations (AMOs) on behalf of the Frax protocol. AMOs are autonomous, contract-controlled strategies that manage the protocol's collateral and FXS supply to maintain the FRAX peg and generate protocol revenue. Keepers are the operational link between on-chain AMO contracts and real-world market conditions, responsible for triggering rebalancing actions when predefined thresholds are met.

Each AMO contract—such as the Curve AMO, Uniswap V3 AMO, or Lending AMO—has distinct operational triggers, profit-cycling logic, and risk parameters. Keepers must monitor collateral ratios, pool imbalances, and oracle price deviations to determine when to mint or redeem FRAX, deploy idle collateral, or harvest profits. Misconfiguration or delayed execution can lead to peg instability, inefficient capital allocation, or missed revenue opportunities for veFXS holders. Operators must understand the specific rebalance() and mintRedeem() functions for each AMO type they support.

This runbook is essential for institutional operators, infrastructure providers, and protocol treasury managers who run keeper infrastructure for the Frax ecosystem. It complements the broader veFXS Keeper Network and Frax Oracle Keeper documentation by focusing specifically on the AMO strategy layer. Teams operating AMO keepers should validate their bot logic against the canonical Frax AMO contracts and maintain robust monitoring for trigger conditions, gas price volatility, and MEV exposure. Chainscore Labs can review keeper configurations, assess AMO-specific risk parameters, and provide independent verification of operational readiness before deploying capital to new AMO strategies.

Frax Algorithmic Market Operations (AMO) keepers are off-chain bots that execute permissioned strategy contracts, acting as the autonomic nervous system for the Frax stablecoin protocol. Unlike purely permissionless keeper networks, AMO keepers are operated by the Frax core team and authorized governance multisigs, as each AMO contract controls substantial protocol-owned liquidity and collateral. The keeper's primary function is to continuously monitor on-chain state—including FRAX price, collateral ratios, Curve pool balances, and lending market utilization—and submit transactions to AMO contracts when predefined thresholds are breached.

Each AMO contract implements a specific strategy with hardcoded trigger logic. For example, the Curve AMO monitors the FRAX/USDC pool balance and mints or redeems FRAX to maintain the pool's peg. The Fraxlend AMO monitors utilization rates and adjusts interest rates or supplies liquidity to keep borrowing costs within target bands. The Uniswap V3 AMO manages concentrated liquidity positions, rebalancing ranges when price moves outside active ticks. Keepers call workable() or equivalent view functions to check if a strategy requires action, then submit the appropriate execute() transaction. The operational risk lies in gas pricing, transaction ordering, and MEV exposure—a keeper that submits a rebalance too slowly or at unfavorable gas prices can leak value or fail to restore peg pressure.

Operators running AMO keepers must maintain reliable RPC connections to both Fraxtal and Ethereum L1, as many AMOs bridge liquidity across domains. Monitoring infrastructure should track not only keeper liveness but also strategy-specific metrics: Curve pool imbalance percentages, Fraxlend utilization rates, and Uniswap position range proximity. Chainscore Labs can review keeper configurations, gas strategies, and monitoring dashboards to ensure teams maintain protocol stability without introducing operational blind spots. For teams integrating with AMO-managed liquidity, understanding these trigger patterns is essential for predicting liquidity depth and slippage during volatile market conditions.
