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 spellparams: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 spellparams: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_KEYis 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_URLwhen provided, otherwise chain default RPC where available).
- To force RPC mode: provide
--rpc-urland 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.

Notes
- CLI currently exposes V3 metadata. V4 adapter is available programmatically via
createUniswapV4Adapter().
- For metadata lookups (
tokens,pools), usegrimoire venue uniswap ...even when your spell venue isuniswap_v4.
- Outputs JSON/table;
tokensandpoolsalso support--format spell.
- Prefer
--format jsonfor automation and reproducible snapshots.
- Only metadata is exposed (no on-chain quote endpoints).
