Most "early" plays in your feed have no funding and no product. We filtered for one signal: real capital behind the project. This week that means Paradigm, a16z, Polychain, Hack VC and Foresight Ventures. Six live activities, with links and steps.

PopDEX · Perp DEX

A perpetuals DEX that opened its public beta on October 19. Instead of a points program it runs MegaPop: every week an on-chain draw, settled by a Bitcoin block hash, pays traders from a public prize pool funded by 40% of net trading fees. PopDEX seeded the pool with 150,000 USDT and adds another 100,000 USDT once traders reach 300,000 tickets.

Backers: Foresight Ventures (lead) · $30M seed

How to join:

1. Open app.popdex.xyz and connect a wallet.

2. Trade perps. Eligible trades earn Pop Tickets automatically, and tickets count double for the first six weeks.

3. Every ticket enters the weekly Pop Draw on its own. Full rules: popdex.xyz/docs/product-docs/rewards/megapop

GTE · Perps Exchange

A high-speed onchain exchange that The Block described as a bid for the "world's fastest" DEX. Its founder called October 19 "game start" after more than two years of building. The waitlist is open and hands out points.

Backers: Paradigm (lead) · $15M Series A

How to join:

1. Go to waitlist.gte.xyz, sign in with your email and add a username.

2. Connect X and follow @GTE_XYZ (Instagram works too). Points activate after 24 hours.

3. Share your referral link. Waitlist updates and launch access arrive by email.

Zodl Vault · Privacy Wallet

A self-custody vault for long-term shielded ZEC savings, built by ZODL, the Zcash Open Development Lab. More than 4,100 people signed up for the beta in its first days.

Backers: Paradigm, a16z, Coinbase Ventures, Winklevoss Capital, Balaji Srinivasan · $25M

How to join:

1. Go to vault.zodl.com and enter your email.

2. Wait for the invite. Beta access opens 100 people at a time.

3. You need a Mac: the beta is macOS only.

Fhenix · Encrypted L2

Fhenix brings fully homomorphic encryption (FHE) to Ethereum, so contracts can compute on data that stays encrypted. Ahead of its mainnet it opened OnlyFhens, a contributor hub: earn credits, collect badges, climb the leaderboard.

Backers: Hack VC (Series A lead) · $15M Series A + $7M seed

How to join:

1. Open onlyfhens.fhenix.io and connect your wallet.

2. Complete tasks to earn credits and collect badges.

3. Climb the leaderboard. Fhenix hasn't tied credits to any token.

Doma · DomainFi

Doma, built by D3, tokenizes internet domains. Its Frontier program gives priority for names in the 1,000+ new top-level domains coming in ICANN's 2026 round, like .sol, .agent and .btc. Frontier has 66,537 members and $3.2M deposited.

Backers: Paradigm (lead), Coinbase Ventures · $25M Series A (D3)

How to join:

1. Open frontier.d3.com and deposit into a Frontier vault. Every $1 earns 1 point a day, times the epoch rate (4x in Epoch 1).

2. For 8x points, use the SOL vault powered by Loopscale and Sanctum.

3. Use your points to back the extensions you want and get priority on names. Deposits sit with a third-party vault provider, not D3.

DogeOS · Dogecoin L2

An app layer that brings EVM smart contracts to Dogecoin. Its public testnet went live on October 1, and the Grand Heist quest campaign has passed 1 million completed quests. Community boss battles drop limited-time loot.

Backers: Polychain Capital (lead) · $6.9M

How to join:

1. Go to quest.dogeos.com and join the heist by picking a faction.

2. Complete the chapter quests and track your progress there.

3. Join the community boss battles at cctv.dogeos.com. DogeOS says it has no token, so play for the loot, not an airdrop.

Not financial advice. Points, waitlists and testnets don't guarantee a token.
