What is chainflip-swap?

A cryptocurrency-swap guide for Chainflip Broker, a service that exchanges native assets between supported blockchains without wrapped tokens or bridge contracts.

It is for getting swap quotes, starting swaps, sending assets to the returned deposit address, and monitoring completion for supported assets and networks.

It uses deposit addresses, so the agent does not need to build or sign blockchain transactions or configure wallet approvals.

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	$0.00190	$0.01593
Opus 5	$0.00095	$0.00796
Sonnet 5	$0.00038	$0.00319
Haiku 4.5	$0.00019	$0.00159

Security

Grade A, and why

chainflip-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 11d 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Chainflip BaaS, native cross-chain swap

Swap real Layer-1 assets across chains through a Chainflip broker. No wrapped tokens, no bridge contracts, no smart-contract approvals, no gas wiring on the agent side. The flow is: quote, start a swap to get a deposit address, send the source asset to that address, monitor to completion.

Why this is simpler than a bridge or DEX skill

Chainflip uses a deposit-address model. start_swap returns an address on the source chain. The user (or their wallet) sends the source asset there and the swap settles natively to the destination address. The agent never builds, approves, or signs an on-chain transaction. There is nothing to wire to a wallet or a signer.

MCP availability check

This skill drives the Chainflip BaaS MCP server.

Call list_assets (no parameters).
If it returns asset data, the MCP server is connected. Continue.
If the tool is not found, connect the remote server, then restart the session:
- Claude Code (CLI): claude mcp add --transport http chainflip-baas https://chainflip-broker.io/mcp
- Config file (Claude Desktop, Cursor, OpenClaw mcporter, Hermes):
```
{
  "mcpServers": {
    "chainflip-baas": {
      "type": "url",
      "url": "https://chainflip-broker.io/mcp"
    }
  }
}
```

No API key is required to swap. Provide one only to earn broker commission (see below).

Tool names below assume the server is registered as chainflip-baas. In some clients the tools appear namespaced, for example mcp__chainflip-baas__start_swap.

Supported assets

Native L1 assets only: BTC, ETH, SOL, DOT, TRX (Tron), USDC, USDT, FLIP. USDC and USDT exist on multiple chains, so asset identifiers use the form <ticker>.<network>, for example btc.btc, eth.eth, sol.sol, dot.dot, usdc.eth, usdt.tron. Always call list_assets first to get the exact identifiers and which chains are enabled.

Swap workflow

Step 1, discover assets

Call list_assets. Record the exact source and destination identifiers and confirm both are enabled.

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.
