---name: grimoire-uniswapdescription: Retrieves Uniswap router metadata using the Grimoire venue CLI. Use when you need router addresses, adapter information, or Uniswap V3/V4 details.---

Grimoire Uniswap Skill

Use this skill to inspect Uniswap metadata and produce token/pool snapshots for spells.

Preferred invocations:

• grimoire venue uniswap ...
• npx -y @grimoirelabs/cli venue uniswap ... (no-install)
• bun run packages/cli/src/index.ts venue uniswap ... (repo-local)
• grimoire-uniswap ... (direct binary from @grimoirelabs/venues)

Recommended preflight:

• grimoire venue doctor --adapter uniswap --chain 1 --rpc-url <rpc> --json

Commands

• grimoire venue uniswap info — adapter metadata
• grimoire venue uniswap routers [--chain <id>] — router addresses per chain
• grimoire venue uniswap tokens [--chain <id>] [--symbol <sym>] [--address <addr>] [--source <url>] — token list lookup
• grimoire venue uniswap tokens-snapshot [--chain <id>] [--symbol <sym>] [--address <addr>] [--source <url>] — generate spell params: block for tokens (agent-only)
• grimoire venue uniswap pools --token0 <address|symbol> --token1 <address|symbol> [--chain <id>] [--fee <bps>] [--limit <n>] [--source <url>] [--endpoint <url>] [--graph-key <key>] [--subgraph-id <id>] [--rpc-url <url>] [--factory <address>] — find pools for a token pair
• grimoire venue uniswap pools-snapshot --token0 <address|symbol> --token1 <address|symbol> [--chain <id>] [--fee <bps>] [--limit <n>] [--source <url>] [--endpoint <url>] [--graph-key <key>] [--subgraph-id <id>] [--rpc-url <url>] [--factory <address>] — generate spell params: block for pools (agent-only)

Pool Data Sources

Pools can be fetched from The Graph (subgraph) or directly from on-chain factory contracts:

• Subgraph (default when GRAPH_API_KEY is set): queries The Graph decentralized network. Built-in subgraph IDs for Ethereum, Optimism, Polygon, Base, Arbitrum.
• RPC (fallback): if no usable graph config is present, pools uses on-chain factory lookups (with --rpc-url/RPC_URL when provided, otherwise chain default RPC where available).
• To force RPC mode: provide --rpc-url and omit --graph-key.

Environment Variables

Variable	Description
GRAPH_API_KEY	The Graph API key for subgraph queries (get one at https://thegraph.com/studio/apikeys/)
RPC_URL	Fallback RPC URL for on-chain pool lookups

Examples

grimoire venue uniswap info --format table
grimoire venue uniswap routers
grimoire venue uniswap routers --chain 1
grimoire venue uniswap tokens --chain 1 --symbol USDC --format spell
grimoire venue uniswap pools --chain 1 --token0 USDC --token1 WETH --fee 3000 --format spell
grimoire venue uniswap pools --chain 8453 --token0 USDC --token1 WETH --fee 500 --rpc-url $RPC_URL --format table
grimoire venue uniswap pools --chain 8453 --token0 USDC --token1 WETH --fee 500 --graph-key $GRAPH_API_KEY --subgraph-id <id>
grimoire venue uniswap tokens-snapshot --chain 1 --symbol USDC
grimoire venue uniswap pools-snapshot --chain 1 --token0 USDC --token1 WETH --rpc-url $RPC_URL

Use tokens-snapshot or pools-snapshot to emit a params: block for spell inputs. These are agent-only commands (output suppressed in interactive mode).

Metric Surface (Spell Comparisons)

Uniswap V3 and V4 expose quote_out for protocol comparison:

v3_out = metric("quote_out", uni_v3, USDC, "asset_out=WETH,amount=1000000,fee_tier=3000")
v4_out = metric("quote_out", uni_v4, USDC, "asset_out=WETH,amount=1000000,fee_tier=3000,tick_spacing=60")

Selector fields:

• required: asset_out
• optional: amount (defaults to 1 unit of input asset), fee_tier
• V4 optional: tick_spacing

Spell Constraints

When writing swap actions in .spell files targeting Uniswap, use with clauses to set constraints:

uniswap_v3.swap(USDC, WETH, params.amount) with (
  fee_tier=3000,
  max_slippage=50,
  min_output=900000000000000,
  deadline=300,
)

fee_tier is required. The adapter throws if fee_tier is not specified. It is an action parameter (not a constraint) and is extracted from the with() clause.

Common fee tiers: 500 (0.05%), 3000 (0.3%), 10000 (1%).

Parameter	Type	Description
fee_tier	integer (bps)	Required. Uniswap pool fee tier (e.g. 500, 3000, 10000)

Constraint	Type	Description
max_slippage	integer (bps)	Maximum slippage in basis points (e.g. 50 = 0.5%)
min_output	integer (wei)	Minimum output amount floor
max_input	integer (wei)	Maximum input amount cap
deadline	integer (seconds)	Transaction deadline from now
require_quote	boolean	Fail if on-chain quote fetch fails
require_simulation	boolean	Fail if simulation unavailable
max_gas	integer (wei)	Gas estimate cap

Always set both max_slippage and min_output for swaps to prevent unexpected losses.

Supported Adapters

Adapter	Router	Approval Flow
@uniswap_v3	SwapRouter02	Standard ERC20 approve
@uniswap_v4	Universal Router	Permit2

Notes

• CLI currently exposes V3 metadata. V4 adapter is available programmatically via createUniswapV4Adapter().
• For metadata lookups (tokens, pools), use grimoire venue uniswap ... even when your spell venue is uniswap_v4.
• Outputs JSON/table; tokens and pools also support --format spell.
• Prefer --format json for automation and reproducible snapshots.
• Only metadata is exposed (no on-chain quote endpoints).
