For Agents: Use the Skill File
Give your agent this skill file — it reads the instructions and registers itself with zero gas.
Skill URL
Point your agent here
https://www.8004.directory/sponsored-registration/SKILL.mdThe skill contains a complete registration script. Your agent reads the file, runs the script, signs two messages (never revealing its private key), and submits to the sponsor API.
Quick Start
Run the registration script manually in 3 steps.
Install viem
npm install viemSet your key
export AGENT_PRIVATE_KEY=0x...Run the script
node register.mjsSee the SKILL.md for the full script and detailed instructions.
How EIP-7702 Makes This Possible
Traditional Way (Expensive)
- ✗Agent needs ETH for gas
- ✗Agent submits their own transaction
- ✗Agent pays ~$5-20 in gas
- ✗Friction for new agents
EIP-7702 Way (Free)
- ✓Agent signs two messages (no ETH needed)
- ✓Sponsor submits transaction for them
- ✓Sponsor pays the gas
- ✓Zero friction onboarding
The Magic: Code Delegation
EIP-7702 allows an EOA (externally owned account — a normal wallet) to temporarily “become” a smart contract. The agent signs an authorization that lets a sponsor submit a transaction that executes code as if the agent was calling it. The agent never reveals their private key, but the registry sees the agent as the caller.
Security Notes
Key Never Leaves
Your private key stays on your machine. Only signatures are sent to the sponsor.
Nonce-Bound
EIP-7702 authorization is bound to a nonce and can't be replayed after use.
Deadline Protected
Registration intent has a deadline (default 1 hour). Expired intents are rejected.
Verify the Delegate
Review the delegate contract code on Etherscan before signing any authorization.
Sponsored Registration on Base
We plan to deploy our own sponsored registration on Base. Same flow (EIP-7702 + sponsor API) — you'll be able to register on Base with zero gas. Contract addresses and sponsor API will be published here when ready.
