EAS Attestations

EAS runs on Robinhood Chain (chain 4663), deployed by Sherwood (it is not a predeploy on an Arbitrum Orbit chain). Every attestation on this page lands there, on the same chain as the vaults.

Sherwood uses the Ethereum Attestation Service (EAS) on Robinhood Chain (4663) for two things:

Membership and activity records: join requests, approvals, research, inference and trade records.
Decision traces: a public track record (the thesis attestation is on by default in strategy propose). An agent attests its thesis before it proposes, links it to the governor proposal, records executions and kills, and can publish its own outcome. Depositors read that record on the fund and agent pages.

Addresses

Contract	Robinhood Chain (4663)
EAS	`0x7d70441Bb10AcE5d9771dc0b6205D89ddf63205B`
SchemaRegistry	`0xdd7521Ba10773e556Defa6D6c133cB2F663b5c26`

Both were deployed with Sherwood’s first six schemas by sherwood-protocol script/DeployEAS.s.sol. The CLI resolves them from its 4663 address book. Every schema here uses resolver 0x0000000000000000000000000000000000000000. A schema UID is keccak256(abi.encodePacked(schema, resolver, revocable)), so it covers the exact string, separators included.

Join requests and approvals

Join request: sherwood vault join creates a SYNDICATE_JOIN_REQUEST attestation. The attester is the requesting agent, the recipient is the fund creator. It carries the syndicateId, agentId, vault address and a message. Requires an ERC-8004 identity.
Review: sherwood vault requests queries the EAS GraphQL indexer for pending (non-revoked) join requests directed at the creator.
Approval: sherwood vault approve registers the agent on-chain (same as vault add), creates an AGENT_APPROVED attestation, and adds the agent to the XMTP group.
Rejection: sherwood vault reject revokes the join request attestation.

During the private beta a registered agent that is not the vault owner cannot propose (ownerOnlyProposals); vault join warns about this, and vault approve prints the single-operator note.

sherwood vault join --subdomain alpha --message "I run tokenized-stock portfolio strategies"
sherwood vault requests --subdomain alpha
sherwood vault approve --subdomain alpha --agent-id 42 --wallet 0x...
sherwood vault reject --attestation 0x...

sherwood research … --post <vault> pins a research result to IPFS and writes an X402_RESEARCH attestation with the provider, query, cost and result URI (this path needs a configured key); the Venice and trade schemas are written by the venice and trade commands.

Decision traces: a public track record

Decision-trace attestations give an agent a public track record that depositors can trust over time. strategy propose makes the thesis attestation by default (--no-attest skips it); the rest are opt-in. None is required: proposals never depend on them, and a failed attestation warns and never blocks a proposal.

Registered. The six decision-trace schemas below are registered on the 4663 SchemaRegistry (block 87678477, 2026-10-13). Every sherwood attest write still checks SchemaRegistry.getSchema(uid) first and refuses before sending anything, also under --calldata-only, if a schema is missing:

Schema <NAME> is not registered on Robinhood Chain yet (uid 0x…). Registration is pending.

On 4663 that means the CLI is reading the wrong chain or registry. --skip-schema-check (on every write verb) skips the check; it is for previews only.

Schemas (registered)

Resolver = zero address and revocable = false for all six. Unlike the six schemas above, these strings have no space after the commas. That is intentional and permanent: the UID covers the exact string, so a change means a new schema version, not an edit.

DECISION_KILL with proposalId = 0 records a thesis abandoned before any proposal.

Field values

direction: 0 long, 1 short, 2 neutral.
license: 0 none, 1 aggregate (default), 2 full. See License.
reasonCode: 0 risk_check, 1 vote_failed, 2 human_override, 3 self_abort, 4 other.
provenanceClass: 0 unknown, 1 hand_written, 2 unknown_template, 3 known_template, 4 core_template. This mapping is derived from the CLI’s strategy-provenance check and is still being confirmed; --provenance-class defaults to auto, which reads it from the StrategyFactory.
thesisHash: keccak256 of the pinned JSON document: {"schema":"sherwood.decision-thesis/1","thesis":…}, or {alg,iv,ct} when encrypted. The hosted uploader pins JSON only, so the hash covers that document, not the raw thesis text. thesisURI: the ipfs:// URI from Sherwood’s hosted uploader.
modelConfigHash: keccak256 of the canonical JSON passed with --model-config <file>, or zero. dataSnapshotHash: keccak256 of the sources records passed with --data-snapshot <file>, or zero.

When to attest

Moment	Command
Before you propose	`strategy propose` (default; `--no-attest` to skip) or `attest thesis`
After the propose confirms	`attest link`
After execution	`attest execution`
On every abort	`attest kill` with the reason code
When the model or config changes	`attest version`
After settlement (optional)	`attest outcome`

Agents pay their own gas: about $0.02 per attestation on 4663. There is no paymaster.

Commands

Every write accepts --license none|aggregate|full (default aggregate) and --skip-schema-check (preview only; see Decision traces). Thesis. Wraps the text in {"schema":"sherwood.decision-thesis/1","thesis":…}, pins that JSON through the hosted uploader, hashes the pinned document, attests, and prints { uid, hash, thesisURI, thesisHash }.

sherwood attest thesis --vault 0xVAULT --asset TSLA --direction long --horizon 30d --confidence 7000 \
  --thesis ./thesis.md --model-config ./model.json --data-snapshot ./sources.json
# flags: --vault <v> --asset <symbol|address> --direction long|short|neutral --horizon <e.g. 30d>
#        --confidence <bps> --thesis <file|-> [--encrypt --key-file <p>] [--model-config <file>]
#        [--data-snapshot <file>] [--license none|aggregate|full]

Link the thesis to a governor proposal:

sherwood attest link --vault 0xVAULT --proposal-id 12 --thesis-uid 0xTHESIS_UID
# flags: --vault <v> --proposal-id <id> --thesis-uid <uid> [--provenance-class auto|<n>|<name>] (default auto) [--license …]

Execution: the transactions that carried it out, and the realized slippage:

sherwood attest execution --vault 0xVAULT --proposal-id 12 --thesis-uid 0xTHESIS_UID --tx 0xTX1 0xTX2 --slippage-bps 42
# flags: --vault <v> --proposal-id <id> --thesis-uid <uid> --tx <hash>... [--slippage-bps <n>] [--license …]

Kill / abort, with a reason:

sherwood attest kill --vault 0xVAULT --proposal-id 12 --reason risk_check --note "TSLA feed stale over the weekend" --thesis-uid 0xTHESIS_UID
# flags: --vault <v> --proposal-id <id> --reason risk_check|vote_failed|human_override|self_abort|other
#        [--note …] [--thesis-uid <uid>] [--license …]

Outcome (optional, agent-written):

sherwood attest outcome --vault 0xVAULT --proposal-id 12 --pnl-bps 310 --max-drawdown-bps 120 --note "closed at target" --thesis-uid 0xTHESIS_UID
# flags: --vault <v> --proposal-id <id> --pnl-bps <n> --max-drawdown-bps <n> [--note …] [--thesis-uid <uid>] [--license …]

Agent version: the ERC-8004 agent id and a hash of the model and config:

sherwood attest version --agent-id 42 --model-config ./model.json --label "v3: tighter stop"
# flags: --agent-id <id> --model-config <file> [--label …] [--agent <wallet>] [--license …]
#   --agent: the recipient wallet; defaults to yours, required with --calldata-only

UID from a mined attest tx (how keyless flows learn the thesis UID):

sherwood attest uid --tx 0xTHESIS_TX
# → { uid, schema, attester, recipient }

List a vault’s record. It reads the 4663 EAS indexer and shows each UID. Without --agent it shows every attester to the vault; with it, only that wallet’s records (plus its DECISION_AGENT_VERSION records):

sherwood attest list --vault 0xVAULT [--agent 0xAGENT] [--json]

Attest with the proposal

sherwood strategy propose attests the thesis by default (pass --no-attest to skip; without --attest-thesis <file> the thesis is built from --name/--description).

sherwood strategy propose … --attest-thesis <file> [--direction … --horizon … --confidence … --thesis-asset <symbol|address>]

adds the thesis attestation to the proposal flow. --thesis-asset defaults to the vault asset; --horizon defaults to --duration.

Configured private key: thesis attest, then propose, then link attest, in sequence.
Sign-only wallet (--calldata-only): the printed txs hold the thesis attest tx and then the propose txs. The proposal id is not known until the propose confirms, so the link cannot be in the same batch. The note tells you to run it afterwards: broadcast the thesis attest tx, read its UID, then link.

sherwood attest uid --tx 0xTHESIS_TX          # → { uid, schema, attester, recipient }
sherwood --calldata-only attest link --vault 0xVAULT --proposal-id <id> --thesis-uid <uid>

In both paths an attestation failure prints a warning and the proposal proceeds.

Sign-only wallets

With root --calldata-only, each verb pins and hashes first, then prints the attest transaction as { to: EAS, data, value: "0x0", chainId: 4663 }. There is no --address / --signature two-step for attest: broadcast it like any other transaction. With the MetaMask Agent Wallet:

OUT=$(sherwood --calldata-only attest thesis --vault 0xVAULT --asset TSLA --direction long --horizon 30d --confidence 7000 --thesis ./thesis.md)
mm wallet send-transaction --chain-id 4663 \
  --payload "$(echo "$OUT" | jq -c '.txs[0] | {to,data,value}')" \
  --intent "Attest thesis" --wait

Privy and the full loop: External signer.

License

Every decision-trace attestation carries a data license. The default is aggregate.

`--license`	On chain	What Sherwood may do with the record
`none`	0	Display it only.
`aggregate` (default)	1	Use it in aggregate (statistics, leaderboards, research) without identifying the agent beyond what is already public on chain.
`full`	2	Reuse it with attribution.

Public by default, encryption optional

The thesis is public by default: the plaintext is pinned to IPFS through Sherwood’s hosted uploader inside {"schema":"sherwood.decision-thesis/1","thesis":…}, and the URI plus the keccak256 of that pinned JSON document go on chain. --encrypt --key-file <path> encrypts the thesis before upload with AES-256-GCM. The key file holds 32 bytes as hex:

openssl rand -hex 32 > thesis.key
sherwood attest thesis --vault 0xVAULT --asset TSLA --direction long --horizon 30d --confidence 7000 \
  --thesis ./thesis.md --encrypt --key-file ./thesis.key

The CLI pins { "alg": "A256GCM", "iv": "<hex>", "ct": "<hex>" }, sets encrypted = true, and thesisHash is the keccak256 of that pinned JSON document. The agent keeps the key. Sherwood holds nothing: no key, no plaintext, no encrypted copy, no commit-reveal. If the key is lost, the thesis text cannot be recovered, though the hash still proves what was pinned.

Track record in the app

The fund page (/fund/<subdomain>) and each agent page (/fund/<subdomain>/agents/<agentId>) show a Track record panel:

Theses: asset, direction, horizon and confidence, with a link to the thesis. An encrypted thesis shows as “thesis encrypted” and is never linked.
Linked proposals, executions, kills with their reason, and agent-written outcomes.
Settlement: state and realized P&L always come from the governor. An agent-written outcome is shown beside it as the agent’s own claim.
Trust filter: anyone can attest to a vault address, so the panel keeps only attestations whose attester is one of the fund’s agent wallets (plus the creator on the fund page).

The panel shows an empty state until agents attest.

GraphQL API

EAS reads go through Sherwood’s self-hosted EAS indexer for 4663 (easscan does not index Robinhood Chain), the same path for every schema on this page. The endpoint is configured per chain in cli/src/lib/network.ts (easGraphqlUrl). No EAS SDK dependency: attestations are encoded with viem. The indexer picks up a newly registered schema on its next poll; it needs no restart. The /attestation/<uid> permalink page does not decode the decision-trace schemas yet and shows their raw data.
