New agent-first CLI for EAS! 🔥
Now your agents can make and verify attested data directly from the terminal.
npm i -g easctl
github.com/ethereum-attestat…
npm i -g easctl
An EAS CLI with built-in schemas, JSON output for agent toolchains, and support for 12+ chains.
AI agents are starting to operate onchain. For them to be useful, they need trust — identity, credentials, reputation, accountability.
EAS attestations are the primitive for this. Signed, structured, onchain claims that anything in the ecosystem can verify.

TEE attested data 👀
OutLayer just shipped an EAS attester that attaches the hardware proof of its own run to every attestation. Web form or console.
Ethereum Attestation Service (EAS) answers who signed a claim. This attester answers the harder question: can you trust how they got the number. Two things here get called attestation, and the difference is the point. The EAS attestation is the on-chain record of who signed. The teeAttestation field inside it is a hardware proof of how the number was produced.
That proof is an Intel-signed quote of the exact run. It seals sha256 of the input, sha256 of the output, and the hash of the WASM that executed with the repo and commit it was built from. The quote is signed by a certificate chain up to Intel's root CA, so its authenticity roots in the silicon, not in our word for it.
The signing key was generated inside the enclave and has never existed outside it. No human, no browser, no operator has ever seen it.
You build none of it. Hand it a schema and a target contract, and inside the enclave it queries several independent RPCs itself, requires them to agree before it proceeds, computes the value, signs the EAS attestation with that enclave-born key, writes it on-chain, and attaches the quote of its own run. No servers, no key management, and no operator you have to believe. The quote, not us, says what ran.
The code is open source and small enough to review in full. Audit it, or fork it for your own schema. You don't even have to trust that the code you read is the code that ran: each attestation proves which binary produced it. Code can change, but a given attestation cannot lie about what made it.
Pick a preset, fund the enclave-born key with about a dollar of gas, and click. The links below verify themselves.

Excited to launch the new attest org site! ✨
Improved copy and design.
Continuing to build it out.
What do you think so far?

These should be onchain attestations on Mainnet.

[X] I affirm that Ethereum is the world computer, will help assure that every transaction on Earth settles to Ethereum and will maintain an energetic focus on keeping it neutral and trustless global infrastructure, such that ETH becomes the most valuable asset in the world

spicy take from a Binance author evaluating @Sign's attestation service vs EAS.
the promise of EAS is to be open, free, tokenless, and permissionless.
for any chain.
any community.
and any builder.

Builder Highlight!
@BitsaveProtocol has tokenized over 60+ real world businesses onchain across Africa.
They attest to valid business registrations which enable the tokenized businesses to become a yield bearing asset on @base.
Congrats on the progress!!

The attestation from Bitsave:
- gives the real world business an onchain presence, the tokens, and bizmarket as the issuing platform.
- describes the instrument they’re issuing (equity, debt, revenue based, or something experimental)
- references their submitted docs and disclosures (hashed for privacy)

Excited to see how more real world assets are verifiable using attested data.
Congrats to @BitsaveProtocol for making a real impact on local businesses 💙.

Already on it 👋
We've been using EAS as the proof-of-delivery layer in our M2M agent escrow on Base:
Client locks funds in a settlement contract (24h timeout)
AI Architect builds + deploys the requested API
Architect signs an EAS attestation (orderId, deliveryUrl, buildHash)
Contract reads the UID → releases payment
No attestation = no payment. Agents can't fake delivery.
We also open-sourced EasyAttest (easyattest.xyz) a few months ago — a no-code interface for creating EAS schemas, submitting attestations, and querying them on Base. Built exactly for this use case: agents proving work to each other without touching Solidity.
Now adding an agent skill file so any AI agent can discover and use EasyAttest out of the box. Will share when it's up 🔨

This is increasingly relevant in today's a2a and human: agent environments.
If you want a math-based approach to solving reputation where the "reputation score" incentives are balanced, sybil resistant and non-destructive...
This is worth the refresher:

Great open-source library for anyone building reputation systems for onchain agents.
Transitive Trust for P2P Reputation Systems.
100% open-source.
