Web3 profile

The Web3 profile standardizes chain-aware identity and actions without making a blockchain, token, wallet, or economic system mandatory for a Hodos world.

Scope

The profile defines:

• chain identifiers;
• account identifiers;
• wallet/provider session discovery;
• explicit account access;
• typed signing requests;
• transaction requests and lifecycle events;
• asset references;
• verifiable receipts.

Private keys, seed phrases, unrestricted wallet providers, and custody objects MUST NOT cross the Host ABI.

Identifiers

Implementations SHOULD use chain-agnostic identifiers where available:

chain:   eip155:1
account: eip155:1:0x...

The exact standards adopted by a stable profile revision will be listed in its normative references. Adapters MAY support Ethereum, other chains, or non-chain signing systems while presenting the same Hodos capability boundary.

Capabilities

Chain read

:chain/read permits bounded read-only queries on declared chains and methods.

Account access

:wallet/account requests one or more explicit accounts. A grant MUST identify the selected accounts and chains and MUST be revocable.

Signing

:wallet/sign requests a typed or explicitly labelled payload:

{:effect/capability :wallet/sign
 :effect/operation :wallet/sign
 :effect/arguments
 {:chain/id "eip155:1"
  :account/id "eip155:1:0x..."
  :sign/method :personal-sign
  :sign/payload "0x..."
  :sign/purpose "Publish a Hodos world receipt"}}

The host MUST present enough context for meaningful user consent. Generic opaque signing SHOULD be disabled unless an adapter profile explicitly permits it.

Transactions

:wallet/transact requests construction, review, submission, and tracking of a transaction. Submission is a separate user-authorized step from preparation. The world receives transaction identifiers and state changes, never signing material.

Receipts

A Web3 receipt can attach signatures or immutable chain references to the Core receipt format. Chain anchoring proves inclusion or ordering according to the selected chain; it does not by itself prove that the underlying world action was correct, fair, or authorized.

Non-goals

The profile does not define token economics, marketplaces, NFTs, governance, asset custody, legal ownership, or a universal reputation system. Those systems can be built above the profile as world-specific applications.
