Summary

  • Adds ens-agent-identity skill: ENS-based identity layer for Bankr agents
  • Human-readable names via NameStone (gasless offchain subnames, CCIP-Read)
  • Structured metadata via agent:* text records (type, capabilities, chains, a2a endpoint, etc.)
  • ENSIP-25 verification linking ENS names to ERC-8004 on-chain identity on Base
  • Three scripts: set-agent-records.sh, resolve-agent.sh, verify-agent-registration.sh

Why

Bankr agents are currently API keys + wallet addresses — no names, no discoverability, no portable reputation. This skill gives agents human-readable ENS names with structured metadata, and bridges them to ERC-8004 on-chain identity via ENSIP-25 verification.

Tested end-to-end on mainnet

  • Registered alpha-go.bankrtest.eth via NameStone (CCIP-Read resolution confirmed)
  • Registered agent #19327 in ERC-8004 Identity Registry on Base (tx)
  • ENSIP-25 full verification: ENS name linked to ERC-8004 identity confirmed

Context

Part of a broader ENS x Bankr integration proposal covering three phases:

  1. ENS subnames via NameStone (this PR)
  2. Agent metadata via text records (this PR)
  3. ERC-8004 identity & reputation (roadmap)

Infrastructure: NameStone for gasless subname management (built by slobo.eth, ENS Ecosystem steward). Namespace uses mainnet ENS + CCIP-Read (chain-neutral, not pinned to Base).

Test plan

  • Review SKILL.md prompt guide
  • Review agent:* text record schema
  • Review ENSIP-25 verification spec and ERC-7930 encoding
  • Run set-agent-records.sh with a NameStone API key
  • Run resolve-agent.sh against alpha-go.bankrtest.eth
  • Run verify-agent-registration.sh against agent #19327 on Base

ENS-based identity layer for Bankr agents: human-readable names,
structured metadata via text records, and ENSIP-25 verification
linking ENS names to ERC-8004 on-chain identity on Base.

Includes:
- SKILL.md with agent identity prompt guide
- agent:* text record schema (type, capabilities, chains, etc.)
- ENSIP-25 verification spec with ERC-7930 cross-chain encoding
- NameStone integration guide for gasless offchain subnames
- Scripts: set-agent-records, resolve-agent, verify-agent-registration

Tested end-to-end on mainnet:
- Registered alpha-go.bankrtest.eth via NameStone (CCIP-Read)
- Registered agent #19327 in ERC-8004 Identity Registry on Base
- ENSIP-25 full verification: ENS name ↔ ERC-8004 identity confirmed

Pass all user-supplied values ($ENS_NAME, $AGENT_ID, $TEXT_RECORD_KEY)
via environment variables instead of interpolating into inline Node.js
strings. A crafted ENS name could break out of the JS string context
and execute arbitrary code, leaking env vars (NAMESTONE_API_KEY, etc.).

Also: validate AGENT_ID as numeric, URL-encode curl query params,
emit JSON output via JSON.stringify, consolidate redundant Node.js
invocations, merge duplicate case blocks, fix stale llamarpc RPC URL,
and add node_modules/ to .gitignore.

Code review

Found 1 issue:

  1. ABI decoding offset bug in verify-agent-registration.sh permanently breaks ERC-8004 verification. hex.slice(130, 194) reads the first 32 bytes of string data as the length field, instead of the actual length at hex.slice(66, 130). For a tokenURI(uint256) return, the ABI layout after the 0x prefix is: offset (chars 2-65), length (chars 66-129), data (chars 130+). The current code interprets URI bytes as a huge integer for length, then reads past the end of the buffer. Result: REGISTRY_RESULT is always empty, ERC8004_VERIFIED is always false.

Fix:

const length = parseInt(hex.slice(66, 130), 16);
if (length > 0) {
  const str = Buffer.from(hex.slice(130, 130 + length * 2), 'hex').toString('utf8');

hex.slice(130, 194) was reading string data as the length field.
The actual ABI layout for a string return is: offset (chars 2-65),
length (chars 66-129), data (chars 130+). Corrected to slice(66,130)
for length and slice(130, 130+len*2) for data.
