**Question:** How much money has gone into spot XRP and Solana ETFs, and other altcoin ETFs, since they launched?

- Kind: Dashboard in Voltfin Vantage
- Topic: [Markets and trading](https://voltfincrypto.com/topics/trading)
- Chains: Multi-chain, XRP Ledger, Solana
- Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is.

Spot ETFs now hold assets beyond bitcoin and ether, including XRP and SOL, and this dashboard adds each newer altcoin fund, such as those on DOGE, LTC or LINK, as it begins trading. Each fund launched on its own date, so their flows only compare fairly when each is measured from its own first trading day.

It records each fund's published holdings, shares outstanding and NAV every trading day, computes its net flow and adds the flows up from its launch. Holdings are also shown as a share of each asset's circulating supply, read from the XRP Ledger and Solana, so the funds' weight in each market can be seen.

Several SOL funds stake the SOL they hold and pass the rewards into the fund after fees, so the fund list notes each fund's fee, launch date and staking terms from its filings.

## Blueprint

### Overview

Cumulative and daily flows by asset.

- **XRP ETFs, flows since launch** (USD): Net flows into all spot XRP ETFs, summed from the first fund's launch to the latest report.
- **SOL ETFs, flows since launch** (USD): Net flows into all spot SOL ETFs, summed from the first fund's launch to the latest report.
- **Share of XRP supply** (%): XRP held by spot XRP ETFs as a share of XRP's circulating supply on the latest reported day.
- **Share of SOL supply** (%): SOL held by spot SOL ETFs as a share of SOL's circulating supply on the latest reported day.
- **Daily net flows by asset** (USD): Net flow per trading day, stacked by asset, over the selected period.
- **Cumulative flows by asset** (USD): Net flows summed from each asset's first fund launch, one line per asset.

### Funds

Every fund, measured from its own launch.

- **Funds tracked** (count): US spot ETFs on assets other than bitcoin and ether that have started trading.
- **Net flow, latest day** (USD): Net flows into every covered altcoin ETF on the latest reported trading day.
- **Flows by days since launch** (USD): Each fund's cumulative flows against trading days since its own launch, so funds of different ages compare.
- **Funds compared**: Each fund's asset, issuer, launch date, fee, staking terms, holdings, flows since launch and latest file date.

Filters: Asset (XRP, SOL or any other asset with a US spot ETF); Period (Last 30 or 90 days, or since launch).

## How it will be measured

- Each fund's daily net flow is the change in shares outstanding times NAV per share, from its issuer's published files, starting on the fund's first trading day.
- Cumulative flows add each fund's daily net flows from its own launch; asset totals add up the funds that hold that asset.
- Share of supply divides each asset's ETF holdings by its circulating supply on the matching day, read from the XRP Ledger and Solana where those reads exist.
- Tickers, launch dates, fees and staking terms come from fund filings, with the filing date; a fund that has not published for a day is shown as pending, never as zero.

## Data it needs

- `etf_holdings_daily` (to build): Holdings and daily flows of spot crypto ETFs per fund, from issuer-published holdings, matched to custody addresses where they are disclosed.
- `market_caps_daily` (to build): Market capitalization of major assets as circulating supply times a reference price, and each asset's share of the total, per day.
- `staking_networks_daily` (to build): Staked supply, staking ratio, validators and nominal rewards per proof-of-stake network per day.
- Source: Issuer-published daily holdings and shares outstanding for spot XRP, SOL, DOGE, LTC, LINK, HBAR, AVAX and HYPE ETFs (off-chain)
- Source: Daily NAV per share per fund (off-chain)
- Source: Fund tickers, launch dates, fees and staking flags from fund filings (off-chain)
- Source: XRP and SOL circulating supply from the XRP Ledger and Solana reads, for share of supply

## Questions

### What are XRP ETF flows?

They are the net value of shares created or redeemed in spot XRP ETFs on each trading day. Inflows mean the funds grew and took in more XRP; outflows mean shareholders redeemed.

### Do Solana ETFs stake their SOL?

Some do. Funds whose filings allow staking stake part of their SOL with validators and pass the rewards into the fund after fees. The fund list shows each fund's staking terms from its latest filing.

### Which altcoins have spot ETFs?

The fund list shows every US spot ETF on an asset other than bitcoin and ether that has started trading, with its launch date. New funds are added on their first trading day.

### Why compare flows from each fund's launch?

Funds launched on different dates, so totals over the same calendar period favor the older funds. Measuring from each launch shows how fast each fund grew in its own first days, weeks and months.

## Glossary

- **Spot ETF**: An exchange-traded fund that holds the asset itself rather than futures on it.
- **Days since launch**: The count of trading days since a fund's first day, used to compare funds that launched at different times.
- **Staking ETF**: A fund whose filings let it stake the coins it holds and add the rewards, after fees, to its assets.
