# Points Program
Hold supported tokens in your own wallet and earn ZeroDelta Points. How it works, how points are calculated, and the rules.
Hold supported stablecoins and tokenized assets in **your own wallet**, sign a commitment, and earn **ZeroDelta Points** for as long as you keep holding. Nothing is deposited, locked or bridged — your funds never leave your wallet.
{% hint style="info" %}
Points are a record of participation. They carry no promise of any future distribution, value or entitlement.
{% endhint %}
> The ZeroDelta app and API use the internal name **Stakeflow** for this program. The names refer to the same thing.

### At a glance
| | |
| -------------- | ------------------------------------------------------------------------------------- |
| **What earns** | The supported tokens you commit, held in your wallet on a supported chain |
| **Rate** | Currently **1 point per US dollar of value held, per day**, for every supported token |
| **Minimum** | **$10** of each committed token — to join, and to keep earning |
| **Custody** | None. No deposit, no lock, no Points contract. Move your funds whenever you like |
| **Leaving** | Revoke at any time with a signature. Points already earned are never taken away |
| **Wallets** | EVM wallets (including ERC-1271 smart-contract wallets) and Solana wallets |
The live list of supported tokens and chains, with each token's rate, is shown in the [ZeroDelta app](https://www.zerodelta.glacislabs.com/stakeflow).

#### Commit
In the [ZeroDelta app](https://www.zerodelta.glacislabs.com/stakeflow), choose a supported token on a supported chain and the amount you intend to hold. You sign a short statement — EIP-712 typed data on EVM, a signed message on Solana. It is a signature, not a transaction: it costs no gas and moves nothing. The full terms are shown before you sign.
{% endstep %}
{% step %}
#### Hold
Keep the tokens in the same wallet. The Points service reads your balance of each committed token from the public blockchain at times that are not announced in advance.
{% endstep %}
{% step %}
#### Earn
Each reading credits points for the time since the previous reading.
{% endstep %}
{% step %}
#### Revoke (optional)
Sign a revocation for a token whenever you want. Earning on that token stops; everything already earned stays.
{% endstep %}
{% endstepper %}

### How points are calculated
Points accrue per wallet, per chain, per committed token. For each period between two consecutive readings:
```
points = min(balance at previous reading, balance at this reading, committed amount)
× token USD price × rate × days in the period
```
* **The lower balance counts.** A balance earns for a period only if it was there at both ends. Tokens added part-way start earning from the next period; tokens removed stop earning straight away. A token's first reading after it is committed therefore earns nothing — it starts the first period.
* **The commitment is a cap, not a lock.** Hold less than you committed and you earn in proportion to what you hold. Hold more and the excess earns nothing until you sign a new commitment for the larger amount, which replaces the old one. A new commitment or a revocation applies to the whole period in progress.
* **Valued in dollars.** Every token, stablecoins included, is valued at its market USD price, so a dollar of one supported token earns the same as a dollar of another.
* **Weighted by time.** Points scale with the time elapsed in each period.
* **Precise.** Points are computed in high-precision decimal arithmetic and kept at full precision. Each chain's total is shown rounded down to whole points, and a wallet's total adds those chain totals together.
#### Worked example
A wallet commits **1,000 USDC** (price $1.00, rate 1). Readings are shown one day apart to keep the numbers simple — real reading times are not published.
| Reading | Balance | Earning basis | Points for the period |
| --------- | ------- | ------------------------------------ | --------------------- |
| 1 | 1,000 | — first reading | 0 |
| 2 | 1,200 | min(1,000, 1,200, cap 1,000) = 1,000 | 1,000 |
| 3 | 400 | min(1,200, 400, cap 1,000) = 400 | 400 |
| 4 | 1,000 | min(400, 1,000, cap 1,000) = 400 | 400 |
| **Total** | | | **1,800** |

### Rules
Every rule applies **per token and per chain**. The same token on two chains is two separate commitments.
#### Joining
* **You join per chain.** Commit on each chain where you want your balances read; the same address on another chain is not read until it commits there.
* When your signed commitment is submitted, the wallet must hold at least **$10** of that token on that chain, and the committed amount must also be at least $10. For this check a stablecoin counts as $1 per token; other assets use their USD price.
* You can commit several tokens on the same chain. Signing again for a token replaces its previous commitment.
* Sign-ups on a chain, including rejoining after dropping out, are subject to a program-wide daily limit.
#### What is read
Only the tokens you have committed are read. Holding other tokens in the same wallet costs nothing and earns nothing:
| Token on that chain | Read? | Earns on |
| ----------------------------------------------- | ------------------------- | --------------------------------------- |
| Committed | Yes | its balance, up to the committed amount |
| Not committed | No | nothing |
| Revoked, or ended by dropping below the minimum | No, from the next reading | nothing, until it is committed again |
#### Staying eligible
* At every reading, **each committed token** must be worth **$10 or more** in the wallet on that chain. Balances of different tokens are never added together.
* If a committed token is below that, its final period is still paid in proportion to what was held, and that commitment ends. Your other commitments on the chain are not affected.
* To earn on that token again, commit it again. A **24-hour cooldown** applies before recommitting a token that dropped out. If it was your last commitment on that chain, the cooldown covers every token there.
#### Leaving
* Revoke a token at any time by signing a revocation. Earning on that token stops, and the period in progress is not credited for it.
* When no commitment remains on a chain, the wallet stops being read there.
* **Points are never deducted** — not when you revoke, not when you drop below the minimum, and not when you move your funds.
#### Wallet notes
* **Smart-contract wallets** must already be deployed on the chain you commit on.
* **Solana:** balances are read from the wallet's associated token account for each token, which is where modern wallets keep them. Tokens held in any other token account are not counted.

### Architecture
The program runs entirely **off-chain**. There is no Points smart contract: the service only verifies signatures and reads public blockchain state.

| Component | What it does |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Enrolment** | Issues a single-use, short-lived challenge carrying the terms, verifies the signature for the address, checks the minimum, and records the commitment or revocation. |
| **Snapshot engine** | Reads each participating wallet's committed token balances from chain nodes at unannounced times, values them in USD, and credits the period since the previous reading. |
| **Points ledger** | An append-only record of every credited period. Nothing in it can reduce a total, and credited periods are never recalculated. |
| **ZeroDelta API** | Serves points, rates and commitments to the app and to integrators — see the Stakeflow endpoints in the [API reference](/zero-delta/integration-guide/api.md). |

### Fair play
* **Unannounced readings.** Reading times are not published, so a balance cannot be timed around them.
* **Both ends must hold.** Only the lower of two consecutive readings earns, so a short-lived top-up earns nothing.
* **Real funds per commitment.** The $10 minimum applies to every committed token, and the cooldown stops a token from cycling in and out.
* **Your signature only.** Committing and revoking both require the wallet's own signature, and each challenge can be used once.
* **Changes are forward-only.** Rates, supported tokens and minimums may change over time. A change applies from the next reading — including to existing participants when the minimum changes — and points already credited stay as they are.
