What's coming to PONSUM
Shipping next (in final checks now):
1) The certificate. When a report is anchored, ponsum.app/verify returns a certificate card: seal, report ID, tax year, country, method, transaction count, anchored date and the transaction link, with a share link that opens the verification directly. The same card prints as the first page of an anchored report.
2) Ledger view. Transactions become receipt lines: ruled rows, mono amounts aligned on the decimal, the tax year framed as a document with a header and a footer that carries the report ID. The audit trail becomes a numbered ledger with running totals.
3) Compact mode and keyboard mode. A density toggle for wallets with thousands of events, and a hint bar on desktop for the shortcuts that already exist: j and k to move, x to select, c to categorize, i to ignore, / to search.
4) Phone gestures. Swipe right on a transaction to categorize, swipe left to ignore with an undo, long press to select many.
5) A calmer palette and the sparkle system. Neon green stays where it belongs, on the actions; everything else moves to soft tints. The four point mark becomes the loader, the chart marker for taxable events and the seal.
6) Motion that means something. Numbers count up once when a computation finishes, the savings figure pulses once, sync progress fills the mark in phase order. Nothing moves under reduced motion.
Planned after that, in the order we expect to build them:
7) Uniswap V4 liquidity positions tracked as tranches the way V3 positions are today.
8) More jurisdictions with their own rules, starting with the countries users pick most in the app, and per year foreign exchange rates for local currency totals.
9) Accountant workspaces: several clients in one view, batch report generation and anchoring.
10) Real device testing on phones, which so far has been emulated widths only.
Everything above follows the same rules as everything already shipped: read only, client side, priced from onchain trades, verifiable by anyone. PONSUM is software, not tax advice. The app is live at ponsum.app and $PONSUM is on the ponsfamily launchpad.
Multiple wallets. One clear financial picture.
Ponsum consolidates treasury activity into one workspace, classifies on-chain swaps, liquidity movements and fees, and lets your team review or recategorize transactions in bulk.
Export capital gains, income, expenses and transaction records as CSVs for your accountant. From wallet activity to structured books.

Why a tax report is infrastructure for Robinhood Chain, and what PONSUM's reports actually contain
Robinhood Chain is built for regulated assets. Tokenized stocks and ETFs, a dollar settlement token, wallets that belong to people who file returns. That audience does not stay on a chain where the year ends in a spreadsheet nobody trusts. Reporting is the missing layer between "I can trade NVDA onchain at 3 a.m." and "I can hold this position through April." PONSUM is that layer, built from the chain's own data rather than around it.
What is in the report set
Summary: proceeds, cost basis, short and long term gains, income, expenses, fees, transaction count, plus the tax base under the chosen method against the worst allowed method, so the saving is a number, not a slogan.
Capital gains: one line per disposal with the asset, amount, acquisition and disposal dates, proceeds, cost, allocated fee, gain, term, and the lots consumed. The same disposal shows differently under FIFO, HIFO, average cost, UK pooling or Least Tax First Out, and the report names which rule produced it.
Income: airdrops, dividends from Robinhood Token multiplier updates, and other receipts, each valued at the pool price when received and carried into cost basis so it is never taxed twice.
Expenses: gas on disposals folded into cost or proceeds per the jurisdiction's default, everything else listed.
Holdings: what remains at cost and at the current pool price, with unrealized gain and zero basis lots flagged where history began mid stream.
Audit: a numbered ledger of every event, its classification, price source, the receipt it came from, the lots it touched and running totals. This is the document an examiner reads.
Country layouts: a US Form 8949 CSV with short and long term sections, a Schedule D total, UK Section 104 pool statements, and Australian 12 month discount lines. Every export is CSV, JSON or a printable page with the report ID in the footer.
Why this matters to the chain more than to any one user
Tokenized securities need clean tax treatment to be adopted at scale, and clean treatment needs three things the chain itself does not provide: correct identification of the issuer's tokens among the memecoins that copy their names, correct handling of dividends and splits delivered as multiplier updates, and USD valuation at the moment of each event from a source that cannot be argued with. PONSUM does all three from primary data: bytecode checks for the 196 real Robinhood Tokens, decoded UIMultiplierUpdated events, and prices from the WETH/USDG and stock pools at the block.
It also gives the chain something new: verifiable reports. A report ID anchored in the PonsumRegistry ties a tax year, country, method and transaction count to a wallet at a block height. An accountant, an auditor or a counterparty can confirm a document is the one recorded without trusting PONSUM, without an account, from ponsum.app/verify. Corrections supersede rather than overwrite, so the history of a filing is itself onchain.
For the ecosystem that means lower friction everywhere: launchpads whose buyers know their trades will reconcile, LPs who can show a position's cost basis, funds and treasuries with multi wallet workspaces and accountant access grants, and users who can leave a position open across a tax year because closing it is no longer the only way to know what they owe.
What it does not do
PONSUM does not give tax advice, does not custody anything, and does not fill gaps with guesses. Plain ETH sends that leave no log land in Review with their exact amount until you resolve them. Jurisdiction rules are general and dated, and the last decision belongs to a professional. What they get from PONSUM is a report where every figure leads back to a transaction on Robinhood Chain, which is the whole point of putting finance on a chain in the first place.

What counts as a taxable event
Most tax authorities treat crypto assets as property rather than as money. That one idea drives most of the rules. When you get rid of a token, you usually have to work out whether you made a gain or a loss compared with what the token cost you.
In many countries the following are disposals:
+ Selling a token for USDG or for ETH.
+ Swapping one token for another, even when no dollars are involved.
+ Spending a token on something, which in some countries includes paying fees.
+ Giving a token away, in some countries and above certain limits.
Buying a token is usually not taxable in itself, but it sets the cost basis that a later disposal is measured against. Tokens you receive without paying, such as airdrops or rewards, are often taxed as income when they arrive, and their value at that moment becomes their cost basis.
Moving tokens from one wallet you control to another is generally not a disposal. The hard part is showing that both wallets are yours. That is why PONSUM lets you add every wallet to one workspace: transfers between them are recognised as self-transfers and are never counted as taxable.

Use case: one wallet, one tax year, and the Review queue that makes the numbers hold
Take a wallet that did what most people on Robinhood Chain did this year: bought NVDA and SPY tokens with USDG in July, sold part of the NVDA position in August, took a few ponsfamily launches with ETH, added USDG and ETH to a Uniswap V3 position, and moved funds between a hot wallet and a cold one. Paste both addresses into ponsum.app and sync.
What comes back is not a list of transfers but a list of events. The NVDA buy is an acquisition with its USD cost taken from the pool trade in that block. The August sale is a disposal matched against that lot, short term, with the gas fee folded into the cost the way your country's rules say. The launchpad buys are priced from the curve, the sell credits the ETH the router paid out, and the transfers between your two wallets are marked as moves and never taxed. The liquidity position is tracked as dated tranches so a later withdrawal knows which deposit it came from.
Then comes Review, which is where PONSUM differs from a spreadsheet that quietly assumes. The chain logs tokens, not plain ETH, so when this wallet received 0.05 ETH from a bridge with no event attached, the app does not invent a balance. It shows the exact difference between the ETH it can explain and the ETH the node reports, and offers three fixes: paste the transaction hash and it is imported like anything else, add a manual entry, or accept it as an opening balance. The same queue flags a nonce gap (transactions you sent that left no token log), a token with no price source, an unknown incoming transfer that might be income or might be spam, and any balance that would go negative if the classification were wrong.
Each item has a fix, and each fix is recorded as your override, kept apart from what the chain said, so the audit trail shows both. Clear the queue and the tax year is closed: no missing prices, no unexplained ETH, every lot accounted for.
The report set then writes itself. The summary gives short and long term gains, income from airdrops and dividends, expenses, and the saving your chosen method produced against the worst allowed one. Capital gains lists every disposal with acquired and disposed dates, proceeds, cost, fee and gain. The audit report is a numbered ledger of every event, its price source and the lots it consumed, with running totals. Holdings shows what you still own at cost and at today's pool price. US users get a Form 8949 layout as CSV; UK users get pooled figures; Australians see the 12 month discount applied.
The report carries an ID computed from its contents. Anchor it and the ID sits in the registry on Robinhood Chain with the tax year, country, method and transaction count; if you later fix a review item and regenerate, the new report replaces the old one onchain and the old ID shows as superseded. Your accountant opens ponsum.app/verify, drops the file, and sees that what they hold is what was recorded.
That is the whole use case: the chain supplies the facts, PONSUM supplies the classification and the arithmetic, Review supplies the honesty, and the anchor supplies the proof. PONSUM is software, not tax advice; the final read still belongs to a professional, who for once gets a report where every number leads back to a transaction.

PONSUM is the first tax engine that runs entirely on Robinhood Chain data, and it ships today.
There is no indexer behind it. The public node has no trace API and no archive state, so PONSUM reconstructs a wallet from primary sources only: Transfer and Swap logs over the full block range, receipts with Nitro L1 gas, block timestamps, WETH deposits and withdrawals, ponsfamily curve events and V4 PoolManager settlements decoded from real receipts. What the chain cannot tell you, a plain ETH send with no log, is surfaced as an exact reconciliation gap instead of a silent zero.
It knows what a Robinhood Token is. 311 contracts on this chain carry "Robinhood Token" in their name; only 196 are the issuer's 283 byte beacon proxies. PONSUM checks the bytecode, not the string, and it decodes the UI multiplier updates that carry dividends and splits, so a stock token position is tracked the way the issuer accounts for it.
Prices are onchain. Every event is valued from pool swaps near its own block, with hourly series for ETH and the most traded stock tokens rebuilt from the WETH/USDG and stock pools and refreshed every six hours. No API keys, no third party feed, no stale symbol lookups that confuse a memecoin with the real ticker.
The tax engine is pure and deterministic: BigInt amounts, lot matching for FIFO, LIFO, HIFO, average cost, UK same-day and 30-day pooling, and Least Tax First Out, across 24 jurisdictions with their own tax years, holding periods and discounts. Sixty-four tests pin the arithmetic to hand-checked scenarios. Five thousand events compute in under 200 milliseconds in the browser.
Every report has a content hash. Canonical JSON in, keccak out, printed on every page. A workspace with a plan anchors that ID in the PonsumRegistry on Robinhood Chain; the registry also keeps EIP-712 wallet links, accountant grants and per-workspace anchors, and its source is verified on Sourcify as an exact match. Anyone holding the file can prove it is unchanged at ponsum.app/verify.
Everything runs client side and read only. Workspaces live in IndexedDB, the site's RPC proxy refuses every write method, and the only transactions PONSUM ever asks for are the ones you choose: buy a plan in ETH, link a wallet, grant an accountant, anchor a report.
A thank you to @pendle_fi. Watching a team treat yield, maturities and settlement as first class onchain objects set the bar for how seriously financial primitives can be built, and that standard shaped how PONSUM treats a tax year: as data you can reconstruct, verify and own.
This is what onchain finance was supposed to make possible: your entire financial year, reconstructed from public data, priced from public markets, provable by anyone. $PONSUM is live on the ponsfamily launchpad. The app is live at ponsum.app.

How to do your Robinhood Chain taxes with PONSUM, start to finish
1) Open ponsum.app/app and paste any wallet address. No sign up, no signature. Add every wallet you use, give each a label, and PONSUM treats transfers between them as moves, not sales.
2) Press Start sync. The app reads the whole history from the chain in your browser: swaps, Robinhood Token trades, ponsfamily launchpad buys and sells, liquidity positions, wraps, airdrops and gas. A busy wallet takes a minute or two and the progress bar tells you which phase it is in.
3) Pick your country. The globe button opens the list; that choice sets your tax year, holding periods and the cost basis methods you are allowed to use. Twenty-four countries are built in and everything else falls back to general rules.
4) Check Transactions. Every event is already classified and priced in USD from real pool trades near its block. Filter by type, asset, wallet or protocol, search, and fix anything by hand: change a type, set a price, add a note, or ignore it. Spam tokens are filtered out automatically and can be restored from the Spam view.
5) Clear the Review list. This is where PONSUM is honest about gaps: a plain ETH send that leaves no log, a token with no price, a balance that does not add up. Each item shows the exact difference and offers a fix, such as pasting a transaction hash or adding a manual entry, so nothing is guessed.
6) Open Tax reports. Choose the year and a method (FIFO, LIFO, HIFO, average cost, UK pooling, or Least Tax First Out where allowed). The summary shows short and long term gains, income, expenses and the potential saving of your chosen method against the worst one. The Harvest view lists unrealized losses you could still take before the year closes.
7) Download and anchor. Reports come as CSV, JSON or a printable document, including an audit trail with every lot match and a US Form 8949 layout. With a plan (paid once a year in ETH, from 0.004 ETH for 100 transactions) you can anchor the report ID on Robinhood Chain; anyone with the file can then confirm it on ponsum.app/verify.
Working with an accountant? Grant them access in Settings and they see your workspace read only, can generate reports and anchor on your behalf, and can even pay for your plan. PONSUM is software, not tax advice: hand the report to a professional for the final call.
Pay once a year in ETH, onchain. A plan unlocks report downloads and anchoring for one workspace, and anyone can pay for any workspace, so an accountant can cover a client.
