Grimoire Across Skill

Use this skill to query Across Protocol bridge data for cross-chain strategy inputs.

Preferred invocations:

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

Recommended preflight:

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

Commands

• grimoire venue across info — adapter metadata and supported chains
• grimoire venue across chains — list supported bridge chains
• grimoire venue across quote --asset <symbol|address> --from <chainId> --to <chainId> --amount <wei> [--recipient <address>] — get a bridge quote with fees and limits
• grimoire venue across status --tx-hash <hash> [--api-url <url>] — check deposit status by origin tx hash
• grimoire venue across routes --asset <symbol> — list available bridge routes for an asset

Examples

grimoire venue across info
grimoire venue across chains
grimoire venue across quote --asset USDC --from 1 --to 8453 --amount 1000000000
grimoire venue across quote --asset WETH --from 42161 --to 1 --amount 500000000000000000
grimoire venue across status --tx-hash 0xabc123...
grimoire venue across routes --asset USDC
grimoire venue across routes --asset WETH

Supported Chains

Quote Response

The quote command returns:

• inputAmount / outputAmount — amounts in smallest unit (wei)
• estimatedFillTimeSec — expected bridge time
• isAmountTooLow — whether the amount is below minimum
• limits.minDeposit / limits.maxDeposit / limits.maxDepositInstant
• fees.lpFee / fees.relayerGasFee / fees.relayerCapitalFee / fees.totalRelayFee
• route.spokePoolAddress — spoke pool contract used

Metric Surface (Spell Comparisons)

Across exposes quote_out for bridge output comparisons:

across_out = metric("quote_out", across, USDC, "to_chain=8453,amount=1000000")

Selector fields:

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

Spell Constraints

When writing bridge actions in .spell files targeting Across, use with clauses:

across.bridge(USDC, params.amount, 8453) with (
  max_slippage=50,
  require_quote=true,
)

Notes

• Amounts are always in the token's smallest unit (wei). For USDC (6 decimals): 1000 USDC = 1000000000.
• The status command queries the Across public API (https://app.across.to/api/deposits/status).
• Routes are computed from the built-in token registry; use raw addresses for unlisted tokens.
• Prefer --format json in automation; the CLI defaults to toon format for interactive use.
