feat: Zetta B20 Intelligence V1 — token indexer, profiles, activity, Luca skill#130
Merged
Conversation
Financial intelligence layer for B20 tokens, issuers, and agent-linked assets on Base.
Not a token launcher — a token indexer, profiler, and attribution tracker.
Architecture layer added:
ERC-8004 = agent identity
.agent/wallets.json = wallet attribution
B20 = token / asset layer ← this commit
Zetta Books = financial analysis
Luca = explanation layer
Files added:
migrations/2026-06-23_b20-tables.sql
b20_tokens: address, name, symbol, issuer, linked_agent, link_method,
manifest_status, luca_summary
b20_activity: mint/burn/transfer events with tx_hash + log_index unique key
src/lib/b20-client.ts
fetchB20TokenIdentity() — alchemy_getContractMetadata + eth_call fallbacks
fetchB20Activity() — mint scan (from 0x0) + burn filter via alchemy_getAssetTransfers
linkTokenToAgent() — known_token > manifest > candidate matching
deriveManifestStatus() — attributed | candidate | none
buildLucaSummary() — Luca read with data integrity statements baked in
src/lib/b20-db.ts
upsertB20Token(), getB20Tokens(), getB20Token()
upsertB20ActivityBatch(), getB20Activity()
getB20Stats(), buildActivitySummaryFromDb()
src/app/api/admin/index-b20/route.ts (internalAuth)
POST — modes: from_registry | single | activity_only
dry run support, activity scan toggle
src/app/api/b20/tokens/route.ts (public)
GET — list all indexed tokens + stats
src/app/api/b20/tokens/[address]/route.ts (public)
GET — token profile + activity summary
src/app/api/luca/skills/b20-token-analysis/route.ts (v1Auth)
POST — 7th Luca Skill: token identity, issuer, agent link, activity,
luca_read, limitations, data_integrity_warnings
src/app/b20/page.tsx
Public B20 Intelligence page — stats bar, token table, data integrity callout
src/app/b20/[address]/page.tsx
Token profile page — identity, attribution, financial readiness grid,
mint/burn activity, Luca read
src/app/luca-admin/b20-intelligence/page.tsx
Admin indexer UI — mode selector, dry run toggle, activity scan toggle, results table
Data integrity enforced throughout:
token contracts → never books-eligible
token transfers → not operating revenue
issuer wallets → not attributed unless manifest-confirmed
B20 activity → excluded from Agent GDP
SQL migration: run migrations/2026-06-23_b20-tables.sql in Supabase before indexing.

Replace BigInt literals (0n, 10n) with BigInt() constructor calls to target ES2019 compatibility. Fix .select() call with invalid second argument by removing it and using rows.length for the insert count.
