Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00058 | $0.01921 |
| Opus 5 | $0.00029 | $0.00960 |
| Sonnet 5 | $0.00012 | $0.00384 |
| Haiku 4.5 | $0.00006 | $0.00192 |
Grade A, and why
wallets 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 yesterday.
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.

Wallets on Ethereum
What You Probably Got Wrong
EIP-7702 is live. Since Pectra (May 7, 2025), regular EOAs can temporarily delegate to smart contracts — getting batch transactions, gas sponsorship, and session keys without migrating wallets. This is NOT "coming soon." It shipped.
Account abstraction status: ERC-4337 is growing but still early (Feb 2026). Major implementations: Kernel (ZeroDev), Biconomy, Alchemy Account Kit, Pimlico. EntryPoint v0.7: 0x0000000071727De22E5E9d8BAf0edAc6f37da032.
Safe secures $100B+. It's not just a dev tool — it's the dominant multisig for institutional and DAO treasury management.
EIP-7702: Smart EOAs (Live Since May 2025)
EOAs can temporarily delegate control to a smart contract within a single transaction.
How it works:
- EOA signs an authorization to delegate to a contract
- During transaction, EOA's code becomes the contract's code
- Contract executes complex logic (batching, sponsorship, etc.)
- After transaction, EOA returns to normal
What this enables:
- Batch 10 token approvals into one transaction
- Gas sponsorship / meta-transactions for EOA users
- Session keys with limited permissions
- Custom authorization logic
- Eliminates "approval fatigue" (approve + execute → one step)
Status (Feb 2026): Deployed on mainnet. MetaMask, Rainbow adding support. Still early for production agents — use standard EOAs or Safe until tooling matures.

Safe for AI Agents
Pattern: 1-of-2 Safe
- Owner 1: Agent's wallet (hot, automated)
- Owner 2: Human's wallet (cold, recovery)
- Threshold: 1 (agent can act alone)
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.

wallets is a skill published in the GitHub repository ObolNetwork/obol-stack (11 stars, last pushed 2d ago), licensed Apache-2.0. It adds 58 tokens to every session and 1,921 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
