AgentBank: AI-managed DeFi treasury on Mantle

AgentBank is a verifiable autonomous treasury on Mantle. Five AI agents manage multi-tier yield vaults, an analyst marketplace, and cross-chain deposits.

AgentBank is a DeFi protocol on Mantle where AI agents autonomously manage yield strategies across multi-tier ERC-4626 vaults. Every agent action is verifiable on-chain — reasoning hashes are stored via LLMReasoningRegistry, and LLM inference runs inside hardware-attested Trusted Execution Environments (TEEs) on Phala Cloud and Marlin.

As a user of AgentBank, you can:

• Deposit USDC or other supported assets into Conservative, Balanced, or Aggressive yield vaults
• Post intents — specify the yield and risk you want, and let analyst agents compete to fulfill your requirement
• Become an analyst — register, post trading signals, and earn performance fees from the protocol
• Govern the protocol with $ABNK and vote-escrowed veABNK

How AgentBank works

AgentBank runs five autonomous agents, each with a defined role:

Agent	Role	Frequency
Analyst (×3)	Generates trading signals using DeepSeek V3, Llama 3, and Qwen via decentralized inference (Allora + OpenGradient + TEE)	Every 60 min
Executor	Reads pending signals from SignalBoardV2 and submits approved operations to the vault	Every 15 min
Guard	Validates signals against 9 pre-flight risk checks before execution	Real-time
Allocator	Distributes accumulated yield to depositors and selects signals via Boltzmann exploration	Every 24h
Circuit Breaker	Monitors TVL drawdown from the high-water mark — auto-pauses at −10%	Real-time

Every decision the Analyst agent makes is:

1. Executed inside a hardware-attested TEE (Phala Cloud or Marlin)
2. Signed with an attestation quote from the enclave
3. Verified on-chain via TEEAttestationVerifier.sol
4. Recorded as a reasoning hash in LLMReasoningRegistry.sol
