A token-swap tool for exchanging digital tokens across supported blockchain networks. It can compare or use on-chain swaps, gasless orders, and cross-chain transfers.

Getting swap quotes, comparing swap types, executing trades through a connected wallet, and creating unsigned transaction data for signing elsewhere.

It removes the need to manually find a route, build transaction data, and handle each approval step separately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.00792
Opus 5	$0.00030	$0.00396
Sonnet 5	$0.00012	$0.00158
Haiku 4.5	$0.00006	$0.00079

Security

Grade A, and why

1inch-swap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1inch Swap

Use the authenticated MCP tool swap. Do not hand-build calldata for normal flows.

Recommended: connect the user's wallet first (WalletConnect)

Unless the user explicitly wants to sign with their own tooling (private key, cast, viem), offer WalletConnect before executing: pair via the walletconnect tool (see the 1inch-walletconnect skill), then call swap. With an active session, execute defaults to true — the tool handles approve txs, EIP-712 signing, submission, and native escrow sends through the connected wallet, and the user simply approves each prompt in their wallet app. No key handling, no manual signing steps.

Set execute: false only when the user wants unsigned calldata / typed data to sign elsewhere.
Set execute: true explicitly to require a wallet session (errors if not connected).

Modes

Classic — on-chain via aggregation router; user pays gas. preferredType: "classic".
Fusion — gasless intent; resolvers fill. preferredType: "fusion".
Cross-chain — set dstChain; preferredType: "crosschain".

Approaches

Wallet-first (recommended): connect via walletconnect, then call swap with src, dst, amount, chain, from (the connected wallet address). The user approves in their wallet.
Shortcut: call swap directly. Omit preferredType to let the server recommend, or set it explicitly.
Full flow: quoteOnly: true → compare quotes / recommended → execute with chosen preferredType.
Manual Fusion/cross-chain submit (no wallet session): after signing typed data locally, call again with signedOrder + orderHash.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
