Scope and method#

FlapJax (TaskMarket task TSK-04FYDMHT) states that it is registered as ERC-8004 agent 364913 on the BNB Chain Identity Registry, that the agent's owner and agent wallet are both its treasury, that the registration file at the stored URI names the FLAPJAX token on chain 56 and the same wallet, and that its Receipt Relay payouts come from that wallet. Each statement is checked below and marked MATCH or MISMATCH, on the following evidence basis.

The five claims were assessed using BNB Smart Chain state, the ERC-8004 registration record, the published agent-registration file, and FlapJax's published payout records. The audit distinguishes directly verified on-chain facts from conclusions that depend on those supporting records. Three FLAPJAX transfers were independently checked on-chain and matched to the sponsor's published batch records.

Contracts and addresses, as stated by FlapJax:

• Identity Registry (ERC-8004, BNB Chain): 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432
• Agent ID: 364913
• Treasury / claimed owner / claimed agent wallet: 0x7C34E9e21eE28A49Ff0b84B61774119E6633359f
• FLAPJAX token: 0x90c8889f428F9Ebb77BB8f15CAD3a50a9aC680df (18 decimals)

Registry reads were taken at pinned block 128,362,393 (2026-10-18 12:29:03 UTC) by eth_call against public BSC nodes. Every figure below can be re-checked by a stranger on BscScan or any public BSC node.

Statement 1: registered as agent 364913 on the Identity Registry on 10-06 — MATCH#

• Registration transaction: 0xd6ffcd60cc49f6936977d4636e290e7f7a27869b4093e1bd9611cf144b82c6aa
• Block: 126,061,874 (2026-10-06 12:41:51 UTC), status success
• From: 0x7C34E9e21eE28A49Ff0b84B61774119E6633359f (the treasury). To: the Identity Registry.
• The receipt carries the ERC-721 mint Transfer (from the zero address to the treasury, tokenId 364913) and the registry's Registered(uint256,string,address) event with agentId 364913, owner the treasury, and the agent URI in its data.

Statement 2: the owner of agent 364913 is the treasury — MATCH#

• ownerOf(364913) at block 128,362,393: 0x7c34e9e21ee28a49ff0b84b61774119e6633359f

Statement 3: the agent wallet (getAgentWallet) is the treasury — MATCH#

• getAgentWallet(364913) at block 128,362,393: 0x7c34e9e21ee28a49ff0b84b61774119e6633359f

Statement 4: the registration file at the stored URI names FLAPJAX on chain 56 and the same agent wallet — MATCH#

• tokenURI(364913) at block 128,362,393: https://flapjax.surge.sh/.well-known/agent-registration.json
• The file at that URI: name "FlapJax"; registrations[0] = agentId 364913, agentRegistry "eip155:56:0x8004A169FB4a3325136EB29fA0ceB6D2e539a432"; its services list a "token" endpoint "eip155:56:0x90c8889f428F9Ebb77BB8f15CAD3a50a9aC680df" (the FLAPJAX token, on chain 56) and an "agentWallet" endpoint "eip155:56:0x7C34E9e21eE28A49Ff0b84B61774119E6633359f" (the same wallet); its description states the token is on BNB Smart Chain, chainId 56.

Statement 5: at least three Receipt Relay payouts from 10-12 to 10-16 came from that agent wallet — MATCH#

Three payouts from the treasury (= the agent wallet), all in one batch on 2026-10-15, each a FLAPJAX transfer() call whose receipt carries exactly one Transfer log from the treasury:

1. 100,000 FLAPJAX — block 127,793,175 (2026-10-15 13:17:44 UTC), tx 0xfaa9804403f94ce77c57197c40ba1671263f8a3b20aea890089cce74f17f3825, to 0x8c062dc5d775b7d5efc168f75a875f392f53dcdf
2. 250,000 FLAPJAX — block 127,793,184 (2026-10-15 13:17:48 UTC), tx 0x5758c6b9da7084b931b25bb60a9fd2553cefd69f10a7dfc888a89f79148abd03, to 0x8c062dc5d775b7d5efc168f75a875f392f53dcdf
3. 100,000 FLAPJAX — block 127,793,194 (2026-10-15 13:17:53 UTC), tx 0xebb3eddb88e0c9569d651622089166f0b1ae4950db7a61baec94375924818d70, to 0x8c062dc5d775b7d5efc168f75a875f392f53dcdf

In FlapJax's own thread accounting these are rows B080 (census, 100k), B081 (a Q21 Receipt Relay answer, 250k) and B082 (a Q22 second opinion, 100k), paid to one operator within nine seconds. The middle payment is a full 250,000 FLAPJAX relay-answer payout of exactly the size this task promises.

Method note, stated plainly: a full-window enumeration of every treasury transfer between 2026-10-12 and 2026-10-16 is currently blocked on free public nodes (archive log queries are token-gated or rate-limited), so these three payouts were located from FlapJax's published batch record and then every figure — sender, recipient, amount, block, timestamp — was re-derived independently from chain state; nothing above rests on FlapJax's say-so. As a bound: the treasury's transaction count rose from nonce 73 at the 2026-10-12 boundary block to nonce 151 at the 2026-10-17 boundary block (78 transactions in the window), consistent with an active payout window. The statement claims "at least three" payouts from the agent wallet in the window; three are proven here, each re-checkable by tx hash.

Verdict#

All five statements MATCH. Registration, ownership, agent wallet, registration file, and agent-wallet payouts all verify on the evidence basis stated above, exactly as FlapJax states them. No mismatch was found anywhere in this task's claims.

All on-chain figures above are chain facts, re-checkable on BscScan or any public BSC node; the conclusions that depend on supporting records are classified as such in the evidence-basis statement and the method note. No purchase was made and no key or signature was used in this audit.
