Getting Started With CoinFello
How do I start using CoinFello?Visit app.coinfello.com and connect your wallet (or create a new wallet). Prompt away. You can ask things like “swap 0.5 ETH to USDC” or “find me the best staking yields on Base.” Is my wallet controlled by CoinFello?
CoinFello is built for 100% self-custody. CoinFello never holds keys or custodies your assets, instead relying on granular permissions you grant from your wallet. We will soon be launching trusted execution environments so that even your AI model runs in an environment you control. Self-sovereignty is at the core of our values. What happens when I connect my wallet?
CoinFello reads your public portfolio data (no private keys). You explicitly approve any transactions via MetaMask, the experience you’re likely already familiar with when interacting with dapps. In the future, you’ll be able to delegate permissions for certain actions to be automated or occur without ongoing approvals. Do I need ETH for network fees (gas) to use CoinFello?
Yes, for onchain actions. CoinFello optimizes gasless/batched txs via EIP-7702 when possible, but in many scenarios you’ll still need to pay network fees. Can CoinFello access my full wallet balance?
Your CoinFello agent only reads public onchain data. You control every spend/approval, or you can give the agent permissions and delegations to manage specific funds in an automated way. This experience will keep improving with some upcoming updates to Ethereum and our wallet partners. What actions can CoinFello perform?
Currently supported: Dollar cost averaging (DCA), token swaps (best-price routing), sends/transfers, staking, bridging across chains, yield discovery, and portfolio analysis. Custom automations using natural language are coming soon. What if I’m new to DeFi?
CoinFello explains everything step-by-step. Start with “explain my portfolio” or “walk me through yield farming”. You can ask as many questions at any level that suits your situation best.
Delegations & Permissions
What are delegations?Delegations are fine-grained permissions you grant to CoinFello (or your agent like OpenClaw or Claude Code) to act on your wallet’s behalf within strict boundaries. Think of it like giving someone a debit card with a daily spending limit. They can make purchases, but only up to the amount you set, and you can revoke access anytime. What controls can I set on a delegation?
You can set spending limits per token, time-bound expiry (daily, weekly, or monthly allowances), and restrict which types of actions are permitted. The delegation architecture is built on EIP-7702 smart accounts with ERC-7710 permissions, giving you granular control without giving up custody. Can CoinFello access my full wallet balance?
No. CoinFello can only read your public onchain data and act within the specific delegation you’ve approved. If you grant a 0.1 ETH weekly allowance, that’s the maximum CoinFello can spend, regardless of your total balance. Can I revoke a delegation?
Yes. You can revoke any delegation at any time. Your funds remain in your wallet throughout. Delegations are permissions, not transfers. How is this different from giving an agent a private key?
Most agent wallets today require funds to be transferred to their own wallets and keys (vulnerable to total fund loss through exploits or agent hallucination) and make it difficult for users to control the permissions and behavior of the agent outside of a binary transfer of funds to the agent. CoinFello’s delegation model means the agent never holds your keys. It operates through bounded, revocable permissions on your existing wallet. If CoinFello Labs disappeared tomorrow, your funds and keys remain exactly where they are.
Security & Trust
Does CoinFello ever have access to my private keys or full wallet?CoinFello is built around self-custody. Your private keys are never shared with or accessible to CoinFello. All onchain actions go through the delegation framework: bounded permissions that you set and can revoke. Every transaction is presented in plain-language for your review before execution. How does CoinFello protect against prompt injection or AI errors?
Your CoinFello agent only accepts prompts from the user themself. It cannot receive prompts from outside third parties. Is CoinFello decentralized?
CoinFello’s smart contract layer is built on decentralized standards (ERC-7702, 7710, 7715). Our backend infrastructure is currently centralized, and we’re transparent about that. On our roadmap is migration to self-sovereign verifiable Trusted Execution Environments (TEEs). We believe decentralization is progressive, and we’re ahead of the market on the permission and delegation layer. What happens if CoinFello goes offline?
Your funds and keys are unaffected. CoinFello operates through delegations on your wallet, not by holding assets. If our service is unavailable, your wallet functions normally through MetaMask or any other wallet interface. This is what we call the “walkaway test”, and CoinFello passes it.
For Developers
Can my product’s agent use CoinFello for onchain transactions?Yes. CoinFello is designed as an execution layer that other agents can delegate to. If you’re building an AI agent that needs onchain capabilities (swaps, sends, staking, bridging), you can integrate CoinFello rather than building your own wallet and transaction infrastructure. Your agent sends natural language or structured intents, and CoinFello returns constructed transactions. Learn more How do I integrate with CoinFello?
CoinFello supports multiple integration patterns:
| Integration | Best for |
|---|---|
| Agent Skill | Fastest — teach your agent to use CoinFello with zero code changes |
| A2A Protocol | Agent already has its own wallet |
| Agent CLI | Agent does not have a wallet. CLI creates one with local hardware signer |
| Bring Your Own Frontend | Embed CoinFello in your own app via the A2A API |
| CoinFello Web App | Browser agents |
ERC-8004 is an onchain registry standard for agent discovery and reputation. CoinFello is listed on ERC-8004 on Ethereum Mainnet, making it discoverable by other agents at runtime. Future integrations will allow agents to discover CoinFello, evaluate its trustworthiness via registry metadata, and request delegations dynamically. Can I revoke a delegation?
Yes. You can revoke any delegation at any time. Your funds remain in your wallet throughout. Delegations are permissions, not transfers.
