Open standard for connecting AI models to external tools and data sources. Gotts Safe exposes 154 tools via MCP. | | V2 | Uniswap V2. Constant product AMM (x\*y=k) with pair-based pools. | | V3 | Uniswap V3. Concentrated liquidity with tick-based positions. Currently the most liquid version. | | V4 | Uniswap V4. Hook-based pool customization with singleton architecture. Enables vault share pools with NAV-aware pricing. | | UniswapX | Dutch auction order system with off-chain fillers. Provides MEV protection for swaps. | | Permit2 | Uniswap's universal token approval contract (`0x000000000022D473030F116dDEE9F6B43aC78BA3`). Replaces per-contract approvals with a single approval + signature-based permits. | | ERC-8004 | Agent identity standard (mainnet Jan 29, 2026). Provides on-chain identity and reputation for autonomous agents. Co-authored by MetaMask and Google. | | ERC-4626 | Tokenized vault standard. Defines a standard API for yield-bearing vaults with deposit/withdraw/redeem functions and share accounting. | | am-AMM | Auction-Managed AMM. Harberger lease auction mechanism where vault management rights are continuously auctioned. The winning manager pays rent to depositors as real yield. | | CCA | Continuous Clearing Auction. Uniswap's token launch mechanism for fair price discovery. | | Hook | A V4 customization contract deployed at a specific address (mined via HookMiner). Hooks intercept pool lifecycle events (swap, modify position, donate) to add custom logic. | | Tick | Price boundary in V3/V4 concentrated liquidity. Liquidity providers set a lower and upper tick to define their position's active price range. | | TVL | Total Value Locked. The aggregate dollar value of assets deposited in a protocol, pool, or vault. | | Slippage | The difference between expected and actual execution price of a trade, caused by price movement or insufficient liquidity. | | IL | Impermanent Loss. The opportunity cost of providing liquidity versus simply holding the assets. Becomes permanent when the LP exits the position. | | LVR | Loss-Versus-Rebalancing. A measure of the cost imposed on LPs by arbitrageurs who trade against stale AMM prices. Approximately 2.5x lower on Base than Ethereum mainnet due to faster block times (sqrt(12/2) = sqrt(6) ≈ 2.45). | | TEE | Trusted Execution Environment. Hardware-isolated compute environment (e.g., Intel SGX, AWS Nitro). Used by Privy for key management and signing policy enforcement. | | Circuit Breaker | Automatic safety mechanism that halts operations when anomalous conditions are detected. Used in vaults (NAV deviation), protocol fees, and withdrawal monitoring. | | TokenJar | Uniswap protocol fee collection contract (`0xf38521f130fcCF29dB1961597bc5d2B60F995f85`). Accumulates protocol fees for governance distribution. | | Firepit | UNI token burn contract (`0x0D5Cd355e2aBEB8fb1552F56c965B867346d6721`). Permanently removes UNI from circulation. | | PolicyCage | On-chain hard boundaries for AI agent strategy. Defines approved asset lists, max position sizes, strategy whitelists, drawdown tolerance, and rebalance frequency limits. Cannot be bypassed by prompt injection. | | Gotts Safe | The unified Uniswap MCP server (`@gotts.ai/safe`). Provides 154 tools across 30 categories for data, trading, liquidity, vault operations, identity, and safety. | | Gotts Vaults | Permissionless vault factory (`@gotts.ai/vault`). Agents deploy ERC-4626 vaults gated by ERC-8004 identity, with auto-created V4 share pools and am-AMM management auctions. | | Tool Profile | Configuration that controls which MCP tools are loaded by Gotts Safe. Profiles include `data`, `trader`, `lp`, `vault`, `full`, and others. Set via `TOOL_PROFILE` env var. | | Agent Proxy | Time-delayed execution proxy (`@gotts.ai/agent-proxy`). All write operations pass through an announce-wait-execute lifecycle with a mandatory cancellation window. | | MonitorBot | Standalone monitoring process that watches all announced Agent Proxy transactions and can veto suspicious activity during the delay window. | | CancelAuthority | Address or contract authorized to cancel announced transactions during the Agent Proxy delay window. Typically held by the MonitorBot or a multisig. | | NAVAwareHook | V4 hook that prices vault shares at Net Asset Value. Enables depositors to exit a vault by swapping shares on the auto-created V4 pool instead of waiting in a withdrawal queue. | | Delegation DAG | Directed Acyclic Graph of agent-to-agent delegation. Agents can delegate to other agents but cycles are prohibited (A delegates to B delegates to A is invalid). Terminal agents (safety-guardian, risk-assessor) never delegate. | | Session Key | ERC-7715 scoped key that grants limited, time-bound permissions to an agent. Allows agents to execute specific operations without full wallet access. |
