A skill that connects AI agents to Sera Protocol, a service for exchanging stablecoins—digital tokens designed to track currencies—and settling payments in different currencies.

Use it to quote or execute currency swaps, pay invoices in local currencies, value multi-wallet treasuries, find foreign-exchange deals and manage settlement operations.

It provides one agent interface for currency quotes, swaps, treasury values and invoice payments across supported stablecoins and fiat currencies.

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	$0.00090	$0.00638
Opus 5.5	$0.00036	$0.00255
Sonnet 5.5	$0.00018	$0.00128
Haiku 4.5	$0.00009	$0.00064

Measured 2mo ago against content hash d2a5e73359f0, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

sera 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 2mo 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.

What it actually says

Sera — multi-currency settlement skill

Multi-currency settlement infrastructure for AI agents. Connects OpenClaw to Sera Protocol — stablecoin FX with on-chain non-custodial settlement.

Setup

Build the Sera MCP locally (one-time):

git clone https://github.com/sera-cx/sera-mcp
cd sera-mcp && npm install && npm run build

Add Sera to your openclaw.json mcpServers block:

{
  "mcpServers": {
    "sera": {
      "command": "node",
      "args": ["/absolute/path/to/sera-mcp/dist/index.js"],
      "env": {
        "SERA_NETWORK": "mainnet",
        "POLICY_PRESET": "standard"
      }
    }
  }
}

Restart your OpenClaw agent. The sera.* tools are now available.

Verify

In any agent session:

@sera doctor

Expect overall_ok: true with checks for sera_health, network_sanity, tokens_registry, signer_mode, policy.

Common patterns

Pay an invoice in any local currency: sera.pay_invoice finds the cheapest source asset in your treasury.
Treasury value across multiple wallets: sera.treasury_value aggregates and reports in any target currency.
Find FX deals: sera.find_deals scans markets in parallel, diffs against external mid, ranks results.
Maker spread calculator: sera.maker_quote_ladder shows earnings at 5/10/15/25/50/100/200 bps for any pair + notional.

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.
