What is swapper-toolkit CLAUDE.md?

Repository guidance for the Swapper AI Agent Toolkit, a collection of skills for depositing funds, swapping tokens, and managing wallets in decentralized finance, where financial services run on blockchain networks. It explains Swapper Finance and the current deposit skill.

Use it when working on the deposit skill, its deeplink parameters, or the planned token-swap and wallet-management skills.

It gives agents the exact structure and flow for creating a deposit link, including the wallet, blockchain network, and token details. This reduces errors when connecting a user to a DeFi deposit.

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	$0.00599	$0.00599
Opus 5.5	$0.00240	$0.00240
Sonnet 5.5	$0.00120	$0.00120
Haiku 4.5	$0.00060	$0.00060

Security

Grade A, and why

swapper-toolkit CLAUDE.md 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.

Swapper AI Agent Toolkit

This repository contains the Swapper AI Agent Toolkit — skills that give AI agents the ability to deposit funds, swap tokens, and manage wallets in DeFi.

What is Swapper Finance?

Swapper Finance is the payment infrastructure layer for Web3. It lets users and agents deposit funds into DeFi protocols via payment cards (Mastercard, Visa, Apple Pay, Google Pay), crypto transfers, and wallet connections. Supports 170+ countries. Cross-chain via Chainlink CCIP. End-to-end orchestration via Chainlink CRE. Card processing via Mastercard.

How the deposit skill works

Agent calls /swapper-deposit with wallet address, chain, token
Skill generates a Swapper deposit deeplink with correct parameters
Deeplink opens in user's browser
User completes deposit via Swapper widget (card, transfer, or wallet)
Funds land in the target wallet or protocol on the target chain

The skill does NOT execute transactions — it generates a link. The user always confirms.

Deeplink format

integratorId is always d6e438dfa14e80709b19 (hardcoded)

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.
