…ution Profiles give a wallet a public username, name, picture and bio, shown wherever the wallet appears (trades, holders, comments, "launched by", fee recipients, the community feed) and on /u/<username> with a link card. Every write is a wallet signature over a message that spells out every field (EOA, ERC-1271 and ERC-6492 all verify), checked before its single-use nonce is spent. Usernames are a-z 0-9 _, brand / chain / staff names and routes are reserved, a dropped name is held 30 days for its old wallet, and a name changes once per 30 days (free on the first day, and always to claim your own verified X handle from an unverified squatter). The tick needs one public post on X carrying a one-time code bound to the wallet and the handle it signed for, so a copied code is useless from any other account. The post is read from X's oEmbed and embed endpoints plus fxtwitter, no API key; one X account belongs to one wallet; the claimed handle stays hidden until verified; posts are re-read about weekly and a deleted one pauses the tick. If X answers nobody, an admin approves it from /admin. The post earns nothing by itself. Swaps were credited to tx.from, which for ERC-4337 smart wallets is the bundler: their trades would never show their name. The indexer now credits the wallet that actually took or paid the token when the sender never touched it (attribution.ts), keeps tx_from for the record, and drains existing history a batch per poll.
… code, admin queue, holds, soft delete) Attribution no longer reads token transfers: anyone can buy and have the tokens sent to someone else's wallet, which credited the trade to them (and counted them as an outside trader). A swap now moves off tx.from only with proof the account authorized the call: an ERC-4337 EntryPoint transaction credits the sender of the UserOperationEvent that closes the operation containing the swap; a relayed EIP-7702 call credits the delegating account. It is decided at index time, so the receipt-path race that marked smart-wallet swaps as the bundler's is gone. History is checked behind LAUNCH_ATTRIBUTE_BACKLOG=1: a set-based pass marks swaps whose sender moved the token itself, the rest get the on-chain evidence. Profiles: - verifying needs the issued code: a stranger can no longer probe the claimed handle, spend someone's rate limit or push a post into review - the admin queue is a signed read, shows the exact code issued for each pending claim, approves only that claim, refuses a handle another wallet has verified, and can remove a tick - a dropped name is held only if it was kept a day or more; holds yield to the verified owner of that X handle; retired names stay retired - delete keeps the row, so moderation flags, created_at and the rename clock survive a re-create - the weekly re-check confirms the post is still by the bound account (a rename on X updates the handle; another account pauses the tick) - signatures verify on the chain where the wallet's code lives - the code must be its own word in the post; X ids must be decimal - editing keeps a pending X claim known to this browser
…ution, bounded backlog) - signatures: a plain wallet is recovered locally (no RPC); a smart wallet is checked on the chain it signed on (Coinbase Smart Wallet and Safe bind the chain id), only where it is deployed or nowhere yet; deployed only elsewhere → "switch your wallet to <chain>". Round 1 verified on the first chain with code, which locked out wallets signing elsewhere. - attribution: a swap counts for a 4337 account only inside its operation's execution (after the EntryPoint's BeforeExecution, before its UserOperationEvent); a swap made during bundle validation stays on the sender. The 7702 rule is dropped (relayers keep the trade, as before this branch). Checked on live Base v0.6 / v0.7 / v0.8 traffic. - backlog: the last day is always retried (a failed live lookup heals without the flag); full history still needs LAUNCH_ATTRIBUTE_BACKLOG=1; a row whose evidence stays unreadable for 3 tries is marked 'unread' so it cannot stall the queue. - deleting no longer restarts the rename clock; coming back follows the same clock as a rename. Moderation reaches deleted profiles. - the username check never treats the retired-name placeholder as you. - migrate: SET LOCAL lock_timeout 10s, so an ALTER never queues behind a long read (and blocks reads behind it); a timeout fails the release.
…picture Same mark the site shows (WalletAvatar), so the card under a verification post and the profile page read as one person.
…block-bounded retry, spaced tries) - codeChains: a chain whose getCode fails could be where the wallet lives; treating it as "deployed nowhere" let an old owner sign through an ERC-6492 wrapper on another chain. Any failed read now answers "try again", and only complete answers are cached. - the last-day attribution retry is bounded by block number (lowest block with a swap in the last day), so the partial index is scanned as a range instead of walking every unchecked history row each poll. - an unreadable row is retried at most every 10 minutes and retired after three such tries, so a short RPC outage never freezes a smart wallet's trade on its bundler. - the admin queue signs on the connected chain; a failed smart-wallet signature says to switch to Base; a deleted profile has no username to retire.

391-393: 🚀 Performance & Scalability | 🔵 TrivialPlan the first deploy around two blocking index builds on
bb_launch_swaps.
migrate.mjsapplies this schema in one transaction, so these indexes cannot useCREATE INDEX CONCURRENTLY. A plainCREATE INDEXholds a SHARE lock onbb_launch_swapsfor the whole build. That lock blocks the indexer's swap inserts and updates until the build ends.The new
lock_timeout = '10s'limits only the wait to acquire the lock. It does not limit the build time. Right afterADD COLUMN trader_via, every row hastrader_via IS NULL, so the "partial" index covers the full table on its first build.IF NOT EXISTSmakes later deploys cheap, but the first release pays for two full builds.If the table is large, use one of these options:
- Create both indexes with
CREATE INDEX CONCURRENTLYin a separate step outside the transaction, before the release.- Schedule the first deploy for a period when a pause in indexing is acceptable.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
A stranger can use the public X code to spend or redirect the owner's verification attempt.
verifyXPost treats the code as a secret. The code is not a secret after the owner posts it:
- Every
postTextsvariant puts the code in a public post. - The same post links to
/u/<username>, and that page shows the wallet throughCopyChip.
Anyone who reads the post therefore has both wallet and code for POST /api/profile/x. The route needs no signature. Two consequences follow:
- Line 366 spends the
xverify:wallet:${me}bucket (10 per hour) before any judging. A bot that scans X forOL-codes can send 10 badpostUrlvalues and block the owner for an hour. It can repeat this every hour. - When no X source answers (
j.review), the stranger only has to sendx.com/<handle>/status/<any id>. Line 375 then marks the owner's codereview = 'pending'with the stranger'spost_id. The owner's own submission then getsNO_CODE, and the admin reviews a post that the stranger chose.
This breaks the guarantee in the header comment and in api/profile/x/route.ts: "nobody else can probe or spend someone's attempt". Require a wallet signature for verify by running it through admit with a message that names the code and the post id. The rate-limit bucket is then spent only after the wallet is proven, as admit already does for saves.
Proposed direction
-export async function verifyXPost(r: { wallet: unknown; postUrl: unknown; code: unknown }): Promise<...> {
+export async function verifyXPost(r: Signed & { postUrl: unknown; code: unknown }): Promise<...> {
...
- if (rateLimited(`xverify:wallet:${me}`, 10, 60 * 60_000)) return fail("too many tries, wait a bit", 429);
+ const a = await admit(db, r, (wallet, nonce, ts) => buildProfileVerifyMessage({ wallet, nonce, ts, code: code.code, postId: post.id }));
+ if (!a.ok) return a;
+ if (rateLimited(`xverify:wallet:${me}`, 10, 60 * 60_000)) return fail("too many tries, wait a bit", 429);Add buildProfileVerifyMessage to auth.ts. In ProfileSheet.verify(), sign that message and send chain, nonce, ts and signature.

…t text, docs) - X verify: the code goes into a public post, so anyone who read it held the wallet and the code and could spend the owner's tries or, during an X outage, push a post of their choosing into the admin queue. Saving now also returns a private verify key (16 random bytes, stored as sha256, compared in constant time) that only the signer's browser receives and that never appears in the post; verifying requires it, and a request without it spends nothing and says nothing. One signature, as before. - readJson enforces the size cap before buffering: a declared length over the cap is refused, and the stream is read in bytes and cancelled the moment it passes the cap (route handlers have no body limit). - oembedText (CodeQL incomplete multi-character sanitization): after tags are dropped and entities decoded, every remaining angle bracket goes, so no markup can survive in the text (it is only matched, never rendered). - One-line doc comments on the functions this PR adds or changes.

Use p.x_state === "verified" for the verified tick and handle.
shape() sets x for every non-none X state, including pending and reverify. The p.x checks can therefore show the verified tick and expose the handle before verification.

Update the `p.x` checks in this page to require `p.x_state === "verified"`
before rendering the verified tick or exposing the X handle; pending and
reverify states must not be treated as verified.

Prevent the transfer shortcut from finalizing receipt-pending EntryPoint swaps.
When traderOf reads an EntryPoint transaction but the receipt lookup fails, it returns the bundler as trader with trader_via = null. Before the retry logic runs, the set-based update marks the row as tx_from when the bundler appears in a same-transaction token transfer. This can permanently credit the bundler without EntryPoint evidence.
traderOf already reads tx.to; the issue is that the backlog update does not use or persist that information. Persist a distinct pending-receipt state, keep those rows eligible for receipt retries, and exclude them from the transfer shortcut. Do not use token-transfer participation as attribution evidence.

Make the pending-review transition atomic and preserve the profile lock order.
A concurrent saveProfile can consume the code before the current profile update. The profile can then become pending_review without a pending code, so the review queue excludes it.
Acquire the profile advisory lock before the code update. saveProfile acquires this lock before updating the profile and consuming codes. This lock order also prevents the proposed transaction from deadlocking with saveProfile.
Suggested fix
- await db`UPDATE bb_x_codes SET post_id = ${post.id}, submitted_at = now(), review = 'pending' WHERE code = ${code.code} AND used_at IS NULL AND review IS NULL`;

Make the pending-review transition in the review branch atomic: acquire the same
profile advisory lock used by saveProfile before updating the code, then update
the profile in that transaction only if the code update succeeds. If no eligible
code was updated, return the existing NO_CODE conflict response instead of
reporting pending_review.

What people get
/u/<username>with what they launched, their trades, and on-chain counts, plus a link card for X / Telegram / Discord.How it stays safe
_only (no look-alike letters). Brand, chain and staff names and every route are reserved. A name kept for a day or more is held 30 days for its old wallet when dropped. A name can change once per 30 days (free on the first day). A verified X owner can take their own handle from an unverified squatter. Deleting a profile keeps its row, so moderation flags and the rename clock survive a re-create./adminfor a person to approve.Indexer: smart-wallet trades
Swaps were credited to
tx.from. For ERC-4337 smart wallets (Coinbase / Base App) that is the bundler, so those trades never showed the person and never counted as theirs.A swap now moves off the sender only with on-chain proof the account authorized it. The transaction must go to an EntryPoint, and the swap log must sit inside one operation's execution: after the bundle's
BeforeExecution, before that operation'sUserOperationEvent. That event'ssenderis the trader. This was checked on live Base traffic for EntryPoint v0.6, v0.7 and v0.8.Token transfers are never the evidence, because anyone can buy and have the tokens sent to someone else's wallet. Everything else (EOAs, routers, aggregators, relayers) stays on the sender, as before.
Each row keeps
tx_fromand atrader_viamark. Unchecked swaps from the last day are always retried. Full history runs only withLAUNCH_ATTRIBUTE_BACKLOG=1; switch it on after the deploy is verified. A row whose evidence stays unreadable for 3 tries, at least 10 minutes apart, is kept on the sender and markedunread.Schema (idempotent, applied by the release command)
